質問 # 37
Which two use cases would be considered examples of Shadow IT within an organization? (Choose two.)

• A. an unsanctioned Google Drive account used by a corporate user to upload non-sensitive data
• B. an unsanctioned Microsoft 365 OneDrive account being used by a corporate user to upload 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 # 38
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. You can find DLP violations under Forensic profiles.
• C. You must create a forensic profile so that an incident is created.
• D. DLP incidents for a file are not visible when the file is deleted.

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 # 39
You want to prevent Man-in-the-Middle (MITM) attacks on an encrypted website or application. In this scenario, which method would you use?

• A. Use a proxy for the connection.
• B. Use certificate pinning.
• C. Use a stronger encryption algorithm.
• D. Use a weaker encryption algorithm.

正解：B

解説：
Explanation
To prevent Man-in-the-Middle (MITM) attacks on an encrypted website or application, one method that you can use is certificate pinning. Certificate pinning is a technique that restricts which certificates are considered valid for a particular website or application, limiting risk. Instead of allowing any trusted certificate to be used, operators "pin" the certificate authority (CA) issuer(s), public keys or even end-entity certificates of their choice. Certificate pinning helps to prevent MITM attacks by validating the server certificates against a hardcoded list of certificates in the website or application. If an attacker tries to intercept or modify the traffic using a fraudulent or compromised certificate, it will be rejected by the website or application as invalid, even if it is signed by a trusted CA. References: Certificate pinning - IBMCertificate and Public Key Pinning | OWASP Foundation

質問 # 40
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. Policy B is implemented before policy A.
• B. Policy A is implemented before policy B.
• C. The policy order is not important; policies are independent of each other.
• D. These two policies would actually not work together.

正解：A

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. References: Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 5: Real-Time Policies, Lesson 3:
Policy Order.

質問 # 41
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. device classification
• B. access method
• C. protocol version
• D. browser version

正解：A、B

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 # 42
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 a reverse proxy.
• B. Use an API connector
• C. Use a log parser.
• D. Use a forward proxy.

正解：A、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.

(Choose three.)

• A. It simplifies the administrator's job by limiting access to pre-defined availability zones.
• B. It includes direct peering with Microsoft and Google in every data center.
• C. It takes advantage of the public cloud by deploying security services on Google Cloud Platform.
• D. It delivers a single, unified network with no surcharges or reliance on public cloud infrastructure or virtual PoPs.
• E. It is a private security cloud network that is massively over provisioned, highly elastic, and built for scale.

正解：B、D、E

解説：
Explanation
Netskope's NewEdge Security Cloud Network Infrastructure is a global network that powers the Netskope Security Cloud, providing real-time inline and out-of-band API-driven services for cloud and web security.
Three statements that are correct about Netskope's NewEdge Security Cloud Network Infrastructure are:
It includes direct peering with Microsoft and Google in every data center. This means that Netskope has established high-speed, low-latency connections with these major cloud service providers, ensuring optimal performance and user experience for their customers. Direct peering also reduces the risk of network congestion, packet loss, or routing issues that may affect the quality of service.
It is a private security cloud network that is massively over provisioned, highly elastic, and built for scale. This means that Netskope owns and operates its own network infrastructure, without relying on third-party providers or public cloud platforms. Netskope has invested over $150 million to build the world's largest and fastest security private cloud, with data centers in more than 65 regions and growing.
Netskope can dynamically scale its network capacity and resources to meet the growing demand and traffic volume of its customers, without compromising on security or performance.
It delivers a single, unified network with no surcharges or reliance on public cloud infrastructure or virtual PoPs. This means that Netskope provides a consistent and transparent network service to its customers, regardless of their location or device. Netskope does not charge any additional fees or hidden costs for accessing its network services, unlike some other providers that may impose surcharges based on geography or bandwidth usage. Netskope also does not use virtual points of presence (PoPs) that are hosted on public cloud platforms, which may introduce latency, complexity, or security risks.

質問 # 44
Which two common security frameworks are used today to assess and validate a vendor's security practices?
(Choose two.)

• A. ISO 27001
• B. NIST Cybersecurity Framework
• C. Building Security in Maturity Model
• D. Data Science Council of America

正解：A、C

解説：
Explanation
The Building Security in Maturity Model (BSIMM) is a framework that measures and compares the security activities of different organizations. It helps organizations to assess their current security practices and identify areas for improvement. ISO 27001 is an international standardthat specifies the requirements for establishing, implementing, maintaining, and improving an information security management system. It helps organizations to manage their information security risks and demonstrate their compliance with best practices. Data Science Council of America (DASCA) is not a security framework, but a credentialing body for data science professionals. NIST Cybersecurity Framework (NIST CSF) is a security framework, but it is not commonly used to assess and validate a vendor's security practices, as it is more focused on improving the cybersecurity of critical infrastructure sectors in the United States. References: [BSIMM], [ISO 27001], [DASCA], [NIST CSF].

質問 # 45
What are two CASB inline interception use cases? (Choose two.)

• A. running a retroactive scan for data at rest in Google Drive
• B. using the Netskope steering client to provide user alerts when sensitive information is posted in Slack
• C. blocking file uploads to a personal Box account
• D. scanning Dropbox for credit card information

正解：B、C

解説：
Explanation
CASB inline interception use cases are scenarios where you need to apply real-time policies and actions on the traffic between users and cloud applications. For example, you may want to block file uploads to a personal Box account to prevent data leakage or exfiltration. You can use Netskope's inline proxy mode to intercept and inspect the traffic between users and Box, and apply granular policies based on user identity, device type, app instance, file metadata, etc. You can also use Netskope's inline proxy mode to provide user alerts when sensitive information is posted in Slack. For example, you may want to warn users when they share credit card numbers or social security numbers in Slack channels or messages. You can use Netskope's steering client to redirect the traffic between users and Slack to Netskope's inline proxy for inspection and enforcement. You can also use Netskope's DLP engine to detect sensitive data patterns and apply actions such as alerting or blocking. References: Netskope Inline Proxy ModeNetskope Steering Client [Netskope DLP Engine]

質問 # 46
You have an issue with the Netskope client connecting to the tenant.
In this scenario, what are two ways to collect the logs from the client machine? (Choose two.)

• A. from the Netskope client system tray icon
• B. from the command line using the nsdiag command
• C. from the Netskope client Ul About page
• D. from the Netskope client Ul Configuration page

正解：B、C

解説：
Explanation
To collect the logs from the client machine when you have an issue with the Netskope client connecting to the tenant, two ways that you can use are: from the Netskope client UI About page and from the command line using the nsdiag command. From the Netskope client UI About page, you can click on the "Collect Logs" button to generate a zip file containing all the relevant logs and configuration files from the client machine.
You can then send this zip file to Netskope support for troubleshooting. From the command line, you can use the nsdiag command with various options to collect different types of logs and diagnostic information from the client machine. For example, you can use nsdiag -l to collect all logs, nsdiag -c to collect configuration files, nsdiag -t to collect traffic statistics, etc. You can also use nsdiag -h to see all available options and usage instructions. You can then send the output files to Netskope support for troubleshooting. References: Netskope Client Configuration overviewInstall and Test the Client - Netskope Knowledge Portal

質問 # 47
Which two technologies form a part of Netskope's Threat Protection module? (Choose two.)

• A. DLP
• B. heuristics
• C. log parser
• D. sandbox

正解：B、D

解説：
Explanation
To protect your users from malicious scripts that may be downloaded from websites, you need to use technologies that can detect and prevent malware, ransomware, phishing, and other advanced threats in web traffic. Two technologies that form a part of Netskope's Threat Protection module, which is a feature in the Netskope platform that provides these capabilities, are sandbox and heuristics. Sandbox is a technology that allows Netskope to analyze suspicious files or URLs in a virtual environment isolated from the rest of the network. It simulates the execution of the files or URLs and observes their behavior and impact on the system.
It then generates a verdict based on the analysis and blocks any malicious files or URLsfrom reaching your users or devices. Heuristics is a technology that allows Netskope to identify unknown or emerging threats based on their characteristics or patterns, rather than relying on predefined signatures or rules. It uses machine learning and artificial intelligence to analyze various attributes of files or URLs, such as file type, size, entropy, metadata, code structure, etc., and assigns a risk score based on the analysis. It then blocks any files or URLs that exceed a certain risk threshold from reaching your users or devices. A log parser or DLP are not technologies that form a part of Netskope's Threat Protection module, as they are more related to discovering cloud applications or protecting sensitive data. References: [Netskope Threat Protection], Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 9: Threat Protection.

質問 # 48
You investigate a suspected malware incident and confirm that it was a false alarm.

• A. Add the hash to the file filter.
• B. Export the packet capture to a pcap file.
• C. In this scenario, how would you prevent the same file from triggering another incident?
• D. Quarantine the file. Look up the hash at the VirusTotal website.

正解：A

解説：
Explanation
A file filter is a list of file hashes that you can use to exclude files from inspection by Netskope. By adding the hash of the file that triggered a false alarm to the file filter, you can prevent it from being scanned again by Netskope and avoid generating another incident. Quarantining the file, exporting the packet capture, or looking up the hash at VirusTotal are not effective ways to prevent the same file from triggering another incident, as they do not affect how Netskope handles the file. References: Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 6: Data Loss Prevention, Lesson 2: File Filters.

質問 # 49
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. Netskope does not support GRE tunnels.
• B. The pre-shared key for the GRE tunnel is incorrect.
• C. The configured GRE peer in the Netskope platform is incorrect.
• D. The route map was applied to the wrong router interface.
• E. The corporate firewall might be blocking GRE traffic.

正解：C、D、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 # 50
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. Allow the user to browse uncategorized domains but restrict edit activities.
• B. Block known bad websites and enable RBI to uncategorized domains.
• C. Allow a limited amount of domains and block everything else.
• D. Block malware detected on download activity for all remaining categories.

正解：B、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 # 51
What are two reasons why legacy solutions, such as on-premises firewalls and proxies, fail to secure the data and data access compared to Netskope Secure Web Gateway? (Choose two.)

• A. Legacy solutions do not meet compliance standards.
• B. Legacy solutions are unable to see the user who is trying to access the application.
• C. The users accessing this data are not in one central place.
• D. The applications where the data resides are no longer in one central location.

正解：C、D

解説：
Explanation
Legacy solutions, such as on-premises firewalls and proxies, fail to secure the data and data access compared to Netskope Secure Web Gateway because they are designed for a perimeter-based security model, where the applications and the users are both within the corporate network. However, with the rise of cloud computing and remote work, this model is no longer valid. The applications where the data resides are no longer in one central location, but distributed across multiple cloud services and regions. The users accessing this data are not in one central place, but working from anywhere, on any device. Legacy solutions cannot provide adequate visibility and control over this dynamic and complex environment, resulting in security gaps and performance issues. Netskope Secure Web Gateway, on the other hand, leverages a cloud-native architecture that provides high-performance and scalable inspection of traffic from any location and device, as well as granular policies and advanced threat and data protection for web and cloud applications.

質問 # 52
You consume application infrastructure (middleware) capabilities by a third-party provider. What is the cloud service model that you are using in this scenario?

• A. PaaS
• B. SaaS
• C. MaaS
• D. DaaS

正解：A

解説：
Explanation
If you consume application infrastructure (middleware) capabilities by a third-party provider, then the cloud service model that you are using in this scenario is PaaS, which stands for Platform as a Service. PaaS is a cloud service model that provides customers with a platform to develop, run, and manage applications without having to deal with the underlying infrastructure or software. PaaS typically includes middleware capabilities such as databases, web servers, development tools, integration services, etc., that customers can use to build and deploy their applications faster and easier. MaaS, DaaS, and SaaS are not cloud service models that match this scenario, as they stand for different types of services. MaaS stands for Monitoring as a Service, which is a service that provides customers with tools to monitor and manage their cloud resources and performance.
DaaS stands for Desktop as a Service, which is a service that provides customers with virtual desktops that they can access from any device or location. SaaS stands for Software as a Service, which is a service that provides customers with software applications that they can use over the internet without installing or maintaining them. References: [PaaS], [MaaS], [DaaS], [SaaS].

質問 # 53
You want to use an out-of-band API connection into your sanctioned Microsoft 365 OneDrive for Business application to find sensitive content, enforce near real-time policy controls, and quarantine malware.
In this scenario, which primary function in the Netskope platform would you use to connect your application to Netskope?

• A. laaS API-enabled Protection
• B. DLP forensics
• C. SaaS API-enabled Protection
• D. Risk Insights

正解：C

解説：
Explanation
SaaS API-enabled Protection is a primary function in the Netskope platform that allows customers to connect their sanctioned SaaS applications to Netskope using out-of-band API connections. This enables customers to find sensitive content, enforce near real-time policycontrols, and quarantine malware in their SaaS applications without affecting user experience or performance. If you want to use an out-of-band API connection into your sanctioned Microsoft 365 OneDrive for Business application to achieve these goals, you should use SaaS API-enabled Protection as the primary function in the Netskope platform. DLP forensics, Risk Insights, and IaaS API-enabled Protection are not primary functions in the Netskope platform that can be used to connect your application to Netskope. References: [Netskope SaaS API-enabled Protection].

質問 # 54
What correctly defines the Zero Trust security model?

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

正解：D

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?
