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.

質問 # 28
You just deployed the Netskope client in Web mode and several users mention that their messenger application is no longer working. Although you have a specific real-time policy that allows this application, upon further investigation you discover that it is using proprietary encryption. You need to permit access to all the users and maintain some visibility.
In this scenario, which configuration change would accomplish this task?
- A. Create a new custom cloud application using the custom connector that can be used in the real-time policy.
- B. Change the real-time policy to block the messenger application.
- C. Edit the steering configuration and add a steering exception for the messenger application.
- D. Add a policy in the SSL decryption section to bypass the messenger domain(s).
正解：D
解説：
Explanation
In this scenario, you have deployed the Netskope client in Web mode, which is a feature that allows you to steer your users' web traffic to Netskope for inspection and policy enforcement. However, some users report that their messenger application is no longer working, even though you have a specific real-time policy that allows this application. Upon further investigation, you discover that the messenger application is using proprietary encryption, which means that Netskope cannot decrypt or inspect the traffic from this application.
To resolve this issue, you need to permit access to all the users and maintain some visibility. The configuration change that would accomplish this task is to add a policy in the SSL decryption section to bypass the messenger domain(s). This will allow Netskope to skip the decryption process for the traffic from the messenger application and pass it through without any modification. However, Netskope will still be able to log some basic information about the traffic, such as source, destination, bytes, etc., for visibility purposes.
Changing the real-time policy to block the messenger application, creating a new custom cloud application using the custom connector, or editing the steering configuration and adding a steering exception for the messenger application are not configuration changes that would accomplish this task, as they would either prevent access to the application, require additional steps or resources, or reduce visibility.

質問 # 29
What are two fundamental differences between the inline and API implementation of the Netskope platform?
(Choose two.)
- A. The API implementation can only be used with sanctioned applications.
- B. The inline implementation can only effectively block a transaction in sanctioned applications.
- C. The inline implementation can effectively block a transaction in both sanctioned and unsanctioned applications.
- D. The API implementation can be used with both sanctioned and unsanctioned applications.
正解：A、C
解説：
Explanation
The inline and API implementation of the Netskope platform are two different ways of connecting cloud applications to Netskope for inspection and policy enforcement. Two fundamental differences between them are: The API implementation can only be used with sanctioned applications, which are applications that are approved and authorized by the organization for business use. The API implementation relies on using out-of-band API connections to access data and events from these applications and apply near real-time policies. The inline implementation can effectively block a transaction in both sanctioned and unsanctioned applications, which are applications that are not approved or authorized by the organization for business use.
The inline implementation relies on using in-band proxy or reverse-proxy connections to intercept traffic to and from these applications and apply real-time policies. The API implementation can be used with both sanctioned and unsanctioned applications and the inline implementation can only effectively block a transaction in sanctioned applications are not true statements, as they contradict the actual capabilities and limitations of each implementation method.

質問 # 30
You want to take into account some recent adjustments to CCI scoring that were made in your Netskope tenant.
In this scenario, which two CCI aspects in the Ul would be used in a real-time protection policy? (Choose two.)
- A. App Score
- B. GDPR Readiness
- C. CCL
- D. App Tag
正解：A、D
解説：
Explanation
To take into account some recent adjustments to CCI scoring that were made in your Netskope tenant, you can use the App Tag and App Score aspects in the UI to create a real-time protection policy. The App Tag is a label that indicates the level of enterprise readiness of a cloud app based on its CCI score. The App Score is a numerical value that represents the CCI score of a cloud app based on various criteria such as security, auditability, and business continuity. You can use these aspects to filter cloud apps by their CCI ratings and apply policies accordingly. For example, you can create a policy that blocks access to cloud apps with an App Tag of Poor or an App Score below 50.

質問 # 31
What are two pillars of CASB? (Choose two.)
- A. compliance
- B. cloud native
- C. SASE
- D. visibility
正解：A、D
解説：
Explanation
Two pillars of CASB are visibility and compliance. CASB stands for Cloud Access Security Broker, which is a solution that provides visibility and control over cloud services and web traffic, as well as data and threat protection for cloud users and devices. Visibility is thecapability to identify all cloud services in use and assess their risk factors, such as security, auditability, business continuity, etc. Compliance is the capability to ensure that cloud services and data meet the regulatory standards and policies of the organization or industry, such as GDPR, HIPAA, PCI DSS, etc. References: What Is a Cloud Access Security Broker (CASB)? | MicrosoftCASB Guide: What are the 4 Pillars of CASB? - Security Service Edge
質問 # 32
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. References: Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 5: Real-Time Policies, Lesson 3:
Policy Order.
質問 # 33
Which two common security frameworks are used today to assess and validate a vendor's security practices?
(Choose two.)
- A. Data Science Council of America
- B. Building Security in Maturity Model
- C. NIST Cybersecurity Framework
- D. ISO 27001
正解：B、D
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 # 34
When using an out-of-band API connection with your sanctioned cloud service, what are two capabilities available to the administrator? (Choose two.)
- A. to find sensitive content
- B. to allow real-time access
- C. to quarantine malware
- D. to block uploads
正解：A、C
解説：
Explanation
When using an out-of-band API connection with your sanctioned cloud service, two capabilities available to the administrator are: to quarantine malware and to find sensitive content. An out-of-band API connection is a method of integrating Netskope with your cloud service provider using the APIs exposed by the cloud service.
This allows Netskope to access the data that is already stored in the cloud service and perform retrospective inspection and enforcement ofpolicies. One capability that the administrator can use with an out-of-band API connection is to quarantine malware. This means that Netskope can scan the files in the cloud service for malware, ransomware, phishing, and other threats, and move them to a quarantine folder or delete them if they are found to be malicious. Another capability that the administrator can use with an out-of-band API connection is to find sensitive content. This means that Netskope can scan the files in the cloud service for sensitive data, such as personal information, intellectual property, or regulated data, and apply data loss prevention (DLP) policies to protect them. For example, Netskope can encrypt, redact, or watermark the files that contain sensitive content, or notify the administrator or the file owner about the exposure.

質問 # 35
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?

質問 # 36
Exhibit
Which portion of the interface shown in the exhibit allows an administrator to set severity, assign ownership, track progress, and perform forensic analysis with excerpts of violating content?
- A. Incidents -> DLP
- B. Reports -> New Report
- C. Skope IT-> Alerts
- D. API-enabled Protection -> Inventory
正解：A
解説：
Explanation
The portion of the interface shown in the exhibit that allows an administrator to set severity, assign ownership, track progress, and perform forensic analysis with excerpts of violating content is Incidents -> DLP. 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. You can also assign an owner to an incident, change its status and severity, add notes or comments, and view the excerpts of the violating content that triggered the DLP policy.

質問 # 37
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. References: [Netskope Skope IT Application Events],
[Netskope REST API].
質問 # 38
You need to create a service request ticket for a client-related issue using the Netskope client Ul. In this scenario, you generate the client logs by right-clicking on the system tray icon and choosing
- A. Help
- B. Troubleshoot
- C. Configuration
- D. Save logs
正解：B
解説：
Explanation
To create a service request ticket for a client-related issue using the Netskope client UI, you need to generate the client logs by right-clicking on the system tray icon and choosing Troubleshoot. This will open a window where you can select the option to Save Logs, which will create a zip file containing the client logs. You can then attach this file to your service request ticket and provide any relevant details about the issue. Choosing Save logs, Configuration, or Help will not generate the client logs, as they perform different functions, such as saving the current configuration, opening the settings menu, or opening the help page. References: [Netskope Client Troubleshooting].
質問 # 39
You investigate a suspected malware incident and confirm that it was a false alarm.
- A. Quarantine the file. Look up the hash at the VirusTotal website.
- B. Export the packet capture to a pcap file.
- C. Add the hash to the file filter.
- D. In this scenario, how would you prevent the same file from triggering another incident?
正解：C
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 # 40
Which three technologies describe the primary cloud service models as defined by the National Institute of Standards and Technology (NIST)? (Choose three.)
- A. Platform as a Service (PaaS)
- B. Identity as a Service (IDaaS)
- C. Software as a Service (SaaS)
- D. Cloud Service Provider (CSP)
- E. Infrastructure as a Service (laaS)
正解：A、C、E
解説：
Explanation
The three technologies that describe the primary cloud service models as defined by the National Institute of Standards and Technology (NIST) are Platform as a Service (PaaS), Software as a Service (SaaS), and Infrastructure as a Service (IaaS). These service models are based on the type of computing capability that is provided by the cloud provider to the cloud consumer over a network. According to NIST, these service models have the following definitions:
Platform as a Service (PaaS): The capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages, libraries, services, and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, or storage, but has control over the deployed applications and possibly configuration settings for the application-hosting environment.
Software as a Service (SaaS): The capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through either a thin client interface, such as a web browser (e.g., web-based email), or a program interface. The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Infrastructure as a Service (IaaS): The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls).

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 # 42
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.

質問 # 43
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 certificate pinning.
- B. Use a proxy for the connection.
- C. Use a stronger encryption algorithm.
- D. Use a weaker encryption algorithm.
正解：A
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 # 44
You are working with traffic from applications with pinned certificates. In this scenario, which statement is correct?
- A. An exception should be added to the steering configuration.
- B. The domains used by applications with pinned certificates should be allowed in an inline policy.
- C. Traffic with pinned certificates should be blocked.
- D. The domains used by certificate-pinned applications should be added to the authentication bypass list.
正解：A
解説：
Explanation
When working with traffic from applications with pinned certificates, you should add an exception to the steering configuration to bypass them. Pinned certificates are a security technique that prevents man-in-the-middle attacks by validating the server certificates against a hardcoded list of certificates in the application. If you try to intercept or inspect the traffic from such applications, they will reject the connection or display an error message. Therefore, you should add the domains used by certificate-pinned applications as exceptions in your steering configuration, so that they are not steered to Netskope for analysis and enforcement.
