You are working with a large retail chain and have concerns about their customer data. You want to protect customer credit card data so that it is never exposed in transit or at rest. In this scenario, which regulatory compliance standard should be used to govern this data?

• A. ISO 27001
• B. SOC 3
• C. AES-256
• D. PCI-DSS

正解：D

解説：
Explanation
PCI-DSS stands for Payment Card Industry Data Security Standard, which is a set of security requirements for organizations that handle credit card data. It aims to protect cardholder data from unauthorized access, disclosure, or theft, both in transit and at rest. PCI-DSS covers various aspects of security, such as encryption, authentication, firewall, logging, monitoring, andincident response. If you are working with a large retail chain and have concerns about their customer data, you should use PCI-DSS as the regulatory compliance standard to govern this data. SOC 3, AES-256, and ISO 27001 are not specific to credit card data protection, although they may have some relevance to general security practices. References: [PCI-DSS], [SOC 3], [AES-256],
[ISO 27001].

質問 # 28
How do you provision users to your customer's Netskope tenant? (Choose two.)

• A. Use SCIM.
• B. Use the AD Connector.
• C. Use the Directory Importer.
• D. Use Microsoft Intune.

正解：B、C

解説：
Explanation
To provision users to your customer's Netskope tenant, two methods that you can use are: use the AD Connector and use SCIM. The AD Connector is a tool that allows you to synchronize users and groups from your Active Directory (AD) domain to your Netskope tenant. The AD Connector runs as a Windows service on a machine that has access to your AD domain controller. The AD Connector periodically queries your AD domain for any changes in users and groups and updates them in your Netskope tenant accordingly. The AD Connector also supports filtering users and groups based on attributes or organizational units (OUs). SCIM stands for System for Cross-domain Identity Management, which is a standard protocol for managing user identities across different applications and services. SCIM allows you to provision users and groups from your identity provider (IdP), such as Azure AD or Okta, to your Netskope tenant using APIs. SCIM also supports creating, updating, deleting, and searching users and groups in your Netskope tenant based on your IdP's configuration.

質問 # 29
Your company asks you to obtain a detailed list of all events from the last 24 hours for a specific user. In this scenario, what are two methods to accomplish this task? (Choose two.)

• A. Export the data from Skope IT Application Events.
• B. Use the Netskope reporting engine.
• C. Export the data from Skope IT Alerts.
• D. Use the Netskope REST API.

正解：A、D

解説：
Explanation
In this scenario, there are two methods to obtain a detailed list of all events from the last 24 hours for a specific user. One method is to export the data from Skope IT Application Events, which is a feature in the Netskope platform that allows you to view and analyze all the activities performed by users on cloud applications. You can use filters to narrow down your search by user name, time range, application, activity, and other criteria. You can then export the data to a CSV or JSON file for further analysis or reporting.
Another method is to use the Netskope REST API, which is a programmatic interface that allows you to access and manipulate data from the Netskope platform using HTTP requests. You can use the API to query for events by user name, time range, application, activity, and other parameters. You can then retrieve the data in JSON format for further analysis or integration with other tools. Using the Netskope reporting engine or exporting the data from Skope IT Alerts are not methods to obtain a detailed list of all events from the last 24 hours for a specific user, as they are more suited for generating summary reports or alerts based on predefined criteria or thresholds, rather than granular event data.

質問 # 30

Click the Exhibit button.
Referring to the exhibit, which statement accurately describes the difference between Source IP (Egress) and Source IP (User) address?

• A. Source IP (Egress) is the public IP address of your Internet edge router while Source IP (User) is the address assigned to the endpoint.
• B. You must always leave the source IP fields blank and configure the user identity as a source criteria.
• C. Source IP (Egress) is the IP address of the destination Web server while Source IP (User) is the IP address assigned to your network.
• D. Source IP (Egress) is the IP address assigned to the endpoint host IP address while Source IP (User) is the public IP address of your Internet edge router.

正解：A

解説：
Explanation
The statement that accurately describes the difference between Source IP (Egress) and Source IP (User) address is: Source IP (Egress) is the public IP address of your Internet edge router while Source IP (User) is the address assigned to the endpoint. Source IP (Egress) is the IP address that is visible to external networks when you send traffic from your network to the Internet. It is usually the IP address of your Internet edge router or gateway that performs NAT (Network Address Translation). Source IP (User) is the IP address that is assigned to your endpoint device, such as a laptop or a smartphone, within your network. It is usually a private IP address that is not routable on the Internet. You can use these two criteria to filter traffic based on where it originates from within your network or outside your network.

質問 # 31
Why would you want to define an App Instance?

• A. to differentiate between an enterprise Google Drive instance vs. an enterprise Box instance
• B. to differentiate between an enterprise Google Drive instance vs. a personal Google Drive instance
• C. to enable the instance_id attribute in the advanced search field when using query mode
• D. to create an API Data Protection Policy for a personal Box instance

正解：B

解説：
Explanation
An App Instance is a feature in the Netskope platform that allows you to define and identify different instances of the same cloud application based on the domain name or URL. For example, you can define an App Instance for your enterprise Google Drive instance (such as drive.google.com/a/yourcompany.com) and another App Instance for your personal Google Drive instance (such as drive.google.com). This way, you can differentiate between them and apply different policies and actions based on the App Instance. You would want to define an App Instance to achieve this level of granularity and control over your cloud application activities. Creating an API Data Protection Policy for a personal Box instance, enabling the instance_id attribute in the advanced search field, or differentiating between an enterprise Google Drive instance vs. an enterprise Box instance are not valid reasons to define an AppInstance, as they are either unrelated or irrelevant to the App Instance feature. References: Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 5: Real-Time Policies, Lesson 4: App Instances.

質問 # 33
A customer asks you to create several real-time policies. Policy A generates alerts when any user downloads, uploads, or shares files on a cloud storage application. Policy B blocks users from downloading files from any operating system (OS) other than Mac or Windows for cloud storage. In this case, policy A is least restrictive and policy B is more restrictive.
Which statement is correct in this scenario?

• A. These two policies would actually not work together.
• B. Policy B is implemented before policy A.
• C. Policy A is implemented before policy B.
• D. The policy order is not important; policies are independent of each other.

正解：B

解説：
Explanation
In this scenario, policy B is more restrictive than policy A, as it blocks users from downloading files from any OS other than Mac or Windows for cloud storage, while policy A only generates alerts when any user downloads, uploads, or shares files on a cloud storage application. Therefore, policy B should be implemented before policy A, as the policy order determines the order of evaluation and enforcement of the policies. If policy A is implemented before policy B, then policy B will never be triggered, as policy A will match all the download activities for cloud storage and generate alerts. The policy order is important; policies are not independent of each other, as they may have overlapping or conflicting conditions and actions. These two policies would actually work together, as long as they are ordered correctly.

In this scenario, which Netskope feature would you recommend to the customer?

• A. Netskope Advanced DLP and Threat Protection
• B. Netskope SaaS Security Posture Management (SSPM)
• C. Netskope Cloud Security Posture Management (CSPM)
• D. Netskope Secure Web Gateway (SWG)

正解：C

解説：
Explanation
If a customer wants to detect misconfigurations in their AWS cloud instances, the Netskope feature that I would recommend to them is Netskope Cloud Security Posture Management (CSPM). Netskope CSPM is a service that provides continuous assessment and remediation of public cloud deployments for risks, threats, and compliance issues. Netskope CSPM leverages the APIs available from AWS and other cloud service providers to scan the cloud infrastructure for misconfigurations, such as insecure permissions, open ports, unencrypted data, etc. Netskope CSPM also provides security posture policies, profiles, and rules that can be customized to match the customer's security standards and best practices. Netskope CSPM can also alert, report, or remediate the misconfigurations automatically or manually. References: Netskope CSPMCloud Security Posture Management

質問 # 35
There is a DLP violation on a file in your sanctioned Google Drive instance. The file is in a deleted state. You need to locate information pertaining to this DLP violation using Netskope. In this scenario, which statement is correct?

• A. You can find DLP violations under the Incidents dashboard.
• B. DLP incidents for a file are not visible when the file is deleted.
• C. You can find DLP violations under Forensic profiles.
• D. You must create a forensic profile so that an incident is created.

正解：A

解説：
Explanation
To locate information pertaining to a DLP violation on a file in your sanctioned Google Drive instance, you can use the Incidents dashboard in Netskope. The Incidents dashboard provides a comprehensive view of all the incidents that have occurred in your cloud environment, such as DLP violations, malware infections, anomalous activities, etc. You can filter the incidents by various criteria, such as app name, incident type, severity, user name, etc. You can also drill down into each incident to see more details, such as file name, file path, file owner, file size, file type, etc. The Incidents dashboard can show DLP violations for files that are in a deleted state, as long as they are still recoverable from the trash bin of the app. If the file is permanently deleted from the app, then the incident will not be visible in the dashboard. References: Netskope Incidents Dashboard

質問 # 36
You are creating a real-time policy for cloud applications.
In addition to users, groups, and organizational units, which two source criteria would support this scenario?
(Choose two.)

• A. protocol version
• B. access method
• C. browser version
• D. device classification

正解：B、D

解説：
Explanation
When creating a real-time policy for cloud applications, you can use access method and device classification as source criteria, in addition to users, groups, and organizational units. Access method refers to how the user accesses the cloud application, such as browser, sync client, mobile app, etc. Device classification refers to the type of device used by the user, such as managed or unmanaged, Windows or Mac, etc. These criteria can help you define granular policies based on different scenarios and risks. References: [Creating Real-Time Policies for Cloud Applications]

質問 # 37
Exhibit

A user is connected to a cloud application through Netskope's proxy.
In this scenario, what information is available at Skope IT? (Choose three.)

• A. account instance, URL category
• B. destination IP. OS patch version
• C. username. device location
• D. file version, shared folder
• E. user activity, cloud app risk rating

正解：A、C、E

解説：
Explanation
In this scenario, a user is connected to a cloud application through Netskope's proxy, which is a deployment method that allows Netskope to intercept and inspect the traffic between the user and the cloud application in real time. In this case, Netskope can collect and display various information about the user and the cloud application at Skope IT, which is a feature in the Netskope platform that allows you to view and analyze all the activities performed by users on cloud applications. Some of the information that is available at Skope IT are: username, device location, account instance, URL category, user activity, and cloud app risk rating.
Username is the name or identifier of the user who is accessing the cloud application. Device location is the geographical location of the device that the user is using to access the cloud application. Account instance is the specific instance of the cloud application that the user is accessing, such as a personal or enterprise instance. URL category is the classification of the web page that the user is visiting within the cloud application, such as Business or Social Media. User activity is the action that the user is performing on the cloud application, such as Upload or Share. Cloud app risk rating is the score that Netskope assigns to the cloud application basedon its security posture and compliance with best practices. Destination IP, OS patch version, file version, and shared folder are not information that is available at Skope IT in this scenario, as they are either unrelated or irrelevant to the proxy connection or the Skope IT feature.

質問 # 38
A company is attempting to steer traffic to Netskope using GRE tunnels. They notice that after the initial configuration, users cannot access external websites from their browsers.
What are three probable causes for this issue? (Choose three.)

• A. The pre-shared key for the GRE tunnel is incorrect.
• B. The corporate firewall might be blocking GRE traffic.
• C. The route map was applied to the wrong router interface.
• D. Netskope does not support GRE tunnels.
• E. The configured GRE peer in the Netskope platform is incorrect.

正解：B、C、E

解説：
Explanation
In this scenario, there are three probable causes for the issue of users not being able to access external websites from their browsers after attempting to steer traffic to Netskope using GRE tunnels. One cause is that the configured GRE peer in the Netskope platform is incorrect, which means that the Netskope POP that is supposed to receive the GRE traffic from the customer's network is not matching the IP address of the customer's router that is sending the GRE traffic. This will result in a failure to establish a GRE tunnel between the customer and Netskope. Another cause is that the corporate firewall might be blocking GRE traffic, which means that the firewall rules are not allowing the GRE protocol (IP protocol number 47) or the UDP port 4789 (for VXLAN encapsulation) to pass through. This will result in a failure to send or receive GRE packets between the customer and Netskope. A third cause is that the route map was applied to the wrong router interface, which means that the configuration that specifies which traffic should be steered to Netskope using GRE tunnels was not applied to the correct interface on the customer's router. This will result in a failure to steer the desired traffic to Netskope. The pre-shared key for the GRE tunnel is incorrect is not a probable cause for this issue, as GRE tunnelsdo not use pre-shared keys for authentication or encryption.
Netskope does support GRE tunnels, so this is not a cause for this issue either. References: [Netskope Secure Forwarder], Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module
3: Steering Configuration, Lesson 3: Secure Forwarder.

質問 # 39
You are deploying TLS support for real-time Web and SaaS transactions. What are two secure implementation methods in this scenario? (Choose two.)

• A. Support TLS 1.2 only when 1.3 is not supported by the server.
• B. Require TLS 1.3 for every server that accepts it.
• C. Bypass TLS 1.3 because it is not widely adopted.
• D. Downgrade to TLS 1.2 whenever possible.

正解：A、B

解説：
Explanation
If you are deploying TLS support for real-time Web and SaaS transactions, then you need to use secure implementation methods that ensure the highest level of encryption and security for yourtraffic. Two secure implementation methods in this scenario are: support TLS 1.2 only when 1.3 is not supported by the server and require TLS 1.3 for every server that accepts it. TLS stands for Transport Layer Security, which is a protocol that provides secure communication over the internet by encrypting and authenticating data exchanged between two parties. TLS 1.3 is the latest version of TLS, which offers several improvements over TLS 1.2, such as faster handshake, stronger encryption algorithms, better forward secrecy, and reduced attack surface.
Therefore, it is recommended to use TLS 1.3 whenever possible for real-time Web and SaaS transactions, as it provides better security and performance than TLS 1.2. However, some servers may not support TLS 1.3 yet, so in those cases, it is acceptable to use TLS 1.2 as a fallback option, as it is still considered secure and widely adopted. Bypassing TLS 1.3 because it is not widely adopted or downgrading to TLS 1.2 whenever possible are not secure implementation methods in this scenario, as they would compromise the security and performance of your traffic by using an older or weaker version of TLS than necessary. References: [TLS],
[TLS 1.3].

質問 # 40
According to Netskope. what are two preferred methods to report a URL miscategorization? (Choose two.)

• A. Tag Netskope on Twitter.
• B. Use www.netskope.com/url-lookup.
• C. Use the URL Lookup page in the dashboard.
• D. Email [email protected].

正解：B、C

解説：
Explanation
According to Netskope, two preferred methods to report a URL miscategorization are: use www.netskope.com/url-lookup and use the URL Lookup page in the dashboard. The first method allows you to visit www.netskope.com/url-lookup in your browser and enter any URL that you want to check or report for miscategorization. You will see the current category assigned by Netskope for that URL and you can submit a request to change it if you think it is incorrect. The second method allows you to use the URL Lookup page in the dashboard of your Netskope platform tenant and enter any URL that you want to check or report for miscategorization. You will see the current category assigned by Netskope for that URL and you can submit a request to change it if you think it is incorrect. Emailing [email protected] or tagging Netskope on Twitter are not preferred methods to report a URL miscategorization, as they are not designed for this purpose and may not be as efficient or effective as using the dedicated tools provided by Netskope. References: [Netskope URL Lookup], Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 8: Skope IT, Lesson 2: Page Events.

質問 # 41
You want to enable Netskope to gain visibility into your users' cloud application activities in an inline mode.
In this scenario, which two deployment methods would match your inline use case? (Choose two.)

• A. Use an API connector
• B. Use a forward proxy.
• C. Use a log parser.
• D. Use a reverse proxy.

正解：B、D

解説：
Explanation
To enable Netskope to gain visibility into your users' cloud application activities in an inline mode, you need to use a deployment method that allows Netskope to intercept and inspect the traffic between your users and the cloud applications in real time. Two deployment methods that would match your inline use case are: use a forward proxy and use a reverse proxy. A forward proxy is a deployment method that allows Netskope to act as a proxy server for your users' outbound traffic to the internet. You can configure your users' devices or browsers to send their traffic to Netskope's proxy server, either manually or using PAC files or VPN profiles.
A reverse proxy is a deployment method that allows Netskope to act as a proxy server for your users' inbound traffic from specific cloud applications. You can configure your cloud applications to redirect their traffic to Netskope's proxy server, either using custom URLs or certificates. Using an API connector or a log parser are not deployment methods that would match your inline use case, as they are more suitable for out-of-band modes that rely on accessing data and events from the cloud applications using APIs or logs, rather than intercepting traffic in real time. References: [Netskope Inline CASB], Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 3: Steering Configuration, Lesson 4: Forward Proxy and Lesson 5: Reverse Proxy.

質問 # 42
What are two uses for deploying a Netskope Virtual Appliance? (Choose two.)

• A. as a Secure Forwarder to steer traffic
• B. as an endpoint for Netskope Private Access (NPA)
• C. as a log parser to discover in-use cloud applications
• D. as a local reverse-proxy to secure a SaaS application

正解：A、B

解説：
Explanation
A Netskope Virtual Appliance is a software-based appliance that can be deployed on-premises or in the cloud to provide various functions and features for the Netskope Security Cloud platform. One use for deploying a Netskope Virtual Appliance is as an endpoint for Netskope Private Access (NPA), which is a service that allows users to securely access private applications without exposing them to the internet or using VPNs.
Another use for deploying a Netskope Virtual Appliance is as a Secure Forwarder to steer traffic from on-premises devices or networks to the Netskope platform for inspection and policy enforcement. Using a Netskope Virtual Appliance as a local reverse-proxy to secure a SaaS application or as a log parser to discover in-use cloud applications are not valid uses, as these functions are performed by other components of the Netskope Security Cloud platform, such as the Cloud Access Security Broker (CASB) or the Cloud XD engine. References: Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 2: Architecture Overview; [Netskope Private Access]; [Netskope Secure Forwarder].

Which three security controls are offered by the Netskope Cloud platform? (Choose three.)

• A. data loss prevention for SMTP
• B. cloud security posture management
• C. identity lifecycle management
• D. endpoint anti-malware
• E. threat protection

正解：A、B、E

解説：
Explanation
Three security controls that are offered by the Netskope Cloud platform are: C. cloud security posture management, E. threat protection, and B. data loss prevention for SMTP.
Cloud security posture management is a service that provides continuous assessment and remediation of public cloud deployments for risks, threats, and compliance issues. Netskope CSPM leverages the APIs available from cloud service providers such as AWS, Azure, and GCP to scan the cloud infrastructure for misconfigurations, such as insecure permissions, open ports, unencrypted data, etc. Netskope CSPM also provides security posture policies, profiles, and rules that can be customized to match the security standards and best practices of the organization or industry.
Threat protection is a capability to detect and block malware, ransomware, phishing, and other cyber threats that may compromise cloud data or users. Netskope threat protection uses advanced techniques such as machine learning, sandboxing, threat intelligence, and behavioral analysis to identify and prevent malicious activities in real time.Netskope threat protection also integrates with third-party solutions such as antivirus engines, firewalls, SIEMs, etc., to provide comprehensive defense across the cloud and web1.
Data loss prevention for SMTP is a feature that allows you to protect sensitive data that is sent or received via email. Netskope DLP for SMTP can scan email messages and attachments for predefined or custom data patterns, such as credit card numbers, social security numbers, health records, etc., and apply appropriate actions, such as block, quarantine, encrypt, notify, etc., based on the DLP policies.Netskope DLP for SMTP can also support multiple email domains and routing rules for different groups of users2.

質問 # 45
You are required to mitigate malicious scripts from being downloaded into your corporate devices every time a user goes to a website. Users need to access websites from a variety of categories, including new websites.
Which two actions would help you accomplish this task while allowing the user to work? (Choose two.)

• A. Block malware detected on download activity for all remaining categories.
• B. Allow the user to browse uncategorized domains but restrict edit activities.
• C. Allow a limited amount of domains and block everything else.
• D. Block known bad websites and enable RBI to uncategorized domains.

正解：A、D

解説：
Explanation
To mitigate malicious scripts from being downloaded into your corporate devices every time a user goes to a website, you need to use Netskope's threat protection features to block or isolate potentially harmful web traffic. Two actions that would help you accomplish this task while allowing the user to work are: block malware detected on download activity for all remaining categories and block known bad websites and enable RBI to uncategorized domains. The first action will prevent any files that contain malware from being downloaded to your devices from any website category, except those that are explicitly allowed or excluded by your policies. The second action will prevent any websites that are classified as malicious or phishing by Netskope from being accessed by your users and enable Remote Browser Isolation (RBI) to uncategorized domains, which are domains that have not been assigned a category by Netskope. RBI is a feature that allows users to browse websites in a virtual browser hosted in the cloud, without exposing their devices to any scripts or content from the website. Allowing the user to browse uncategorized domains but restrict edit activities or allowing a limited amount of domains and block everything else are not effective actions, as they may either limit the user's productivity or expose them to unknown risks. References: [Netskope Threat Protection],
[Netskope Remote Browser Isolation].

質問 # 46
Which two use cases would be considered examples of Shadow IT within an organization? (Choose two.)

• A. an unsanctioned Microsoft 365 OneDrive account being used by a corporate user to upload sensitive data
• B. an unsanctioned Google Drive account used by a corporate user to upload non-sensitive data
• C. a sanctioned Salesforce account used by a contractor to upload non-sensitive data
• D. a sanctioned Wetransfer being used by a corporate user to share sensitive data

正解：A、B

解説：
Explanation
Shadow IT is the term for the unauthorized use of IT resources and functions by employees within an organization. It can include cloud services, software, and hardware that are not approved or managed by the IT department. Two use cases that would be considered examples of shadow IT within an organization are: an unsanctioned Microsoft 365 OneDrive account being used by a corporate user to upload sensitive data and an unsanctioned Google Drive account used by a corporate user to upload non-sensitive data. In both cases, the corporate user is using a personal cloud storage service that is not sanctioned by the organization to store work-related data. This can introduce security risks, such as data leakage, data loss, compliance violations, malware infections, etc. The IT department may not have visibility or control over these cloud services or the data stored in them.

質問 # 47
Which two statements describe a website categorized as a domain generated algorithm (DGA)? (Choose two.)

• A. The website is used to hide a command-and-control server.
• B. The domain contains malicious algorithms.
• C. The website is used for domain registration.
• D. The domain was created by a program.

正解：A、D

解説：
Explanation
Two statements that describe a website categorized as a domain generated algorithm (DGA) are: The website is used to hide a command-and-control server and the domain was created by a program. A domain generated algorithm (DGA) is a technique used by cyber attackers to generate new domain names and IP addresses for malware's command and control servers. Executed in a manner that seems random, it makes it nearly impossible for threat hunters to detect and contain the attack. A command-and-control server is a server that communicates with malware installed on infected machines and sends commands or updates to them. A program is a piece of software that performs a specific task or function. A domain generated algorithm is implemented by a program that runs on the attacker's machine or the malware itself, and produces a large number of domain names based on some logic, such as date, time, seed, dictionary, etc. References: Domain generation algorithmAmong cyber-attack techniques, what is a DGA?

質問 # 48
What correctly defines the Zero Trust security model?

• A. double encryption
• B. least privilege access
• C. strong authentication
• D. multi-layered security

正解：B

解説：
Explanation
The term that correctly defines the Zero Trust security model is least privilege access. The Zero Trust security model is a modern security strategy based on the principle: never trust, always verify. Instead of assuming everything behind the corporate firewall is safe, the Zero Trust model assumes breach and verifies each request as though it originates from an open network. One of the core principles of the Zero Trust model is to use least privilege access, which means granting users or systems only the minimum level of access they need to perform their tasks, and only for a limited time. This helps reduce the attack surface and minimize the impact of a potential breach. References: Zero Trust Security - microsoft.comWhat is Zero Trust Security?
