What is the limitation of using a legacy proxy compared to Netskope's solution?
- A. Legacy on-premises solutions fail to provide protection for traffic from on-premises users.
- B. Netskope architecture requires on-premises components.
- C. Legacy solutions offer higher performance and scalability for corporate and remote users.
- D. To enforce policies, traffic needs to traverse back through a customer's on-premises security stack.
正解：D
解説：
Explanation
A limitation of using a legacy proxy compared to Netskope's solution is that to enforce policies, traffic needs to traverse back through a customer's on-premises security stack. This creates latency, bandwidth, and scalability issues for remote users and cloud applications. Netskope's solution, on the other hand, leverages a cloud-native architecture that provides high-performance and scalable inspection of traffic from any location and device.

質問 # 35
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.

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. browser version
- B. access method
- C. protocol 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.

質問 # 37
What are two uses for deploying a Netskope Virtual Appliance? (Choose two.)
- A. as an endpoint for Netskope Private Access (NPA)
- B. as a log parser to discover in-use cloud applications
- C. as a Secure Forwarder to steer traffic
- D. as a local reverse-proxy to secure a SaaS application
正解：A、C
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].

質問 # 39
Which two traffic steering configurations are supported by Netskope? (Choose two.)
- A. all Web traffic including cloud applications
- B. Web traffic only
- C. browser isolation traffic only
- D. cloud applications only
正解：A、D
解説：
Explanation
The two traffic steering configurations that are supported by Netskope are cloud applications only and all Web traffic including cloud applications. These configurations allow you to control what kind of traffic gets steered to Netskope for real-time deep analysis and what kind of traffic gets bypassed. You can choose one of these options for both on-premises and off-premises scenarios, depending on your network environment and security needs. You can also create exceptions for specific domains, IP addresses, or certificate-pinned applications that you want to bypass or steer regardless of the configuration option.

質問 # 40
Which two cloud security and infrastructure enablement technologies does Secure Access Service Edge (SASE) combine into its unified platform? (Choose two.)
- A. Distributed Denial of Service Protection (DDoS)
- B. Zero Trust Network Access (ZTNA)
- C. Unified Threat Management (UTM)
- D. Cloud Access Security Broker (CASB)
正解：B、D
解説：
Explanation
Secure Access Service Edge (SASE) is a cloud-based architecture that combines various cloud security and infrastructure enablement technologies into a unified platform that delivers security and networking services from the edge of the network. Two of these technologies are Zero Trust Network Access (ZTNA) and Cloud Access Security Broker (CASB). ZTNA is a technology that provides secure access to private applications without exposing them to the internet or using VPNs. It uses identity-based policies and encryption to grant granular access to authorized users and devices, regardless of their location or network. CASB is a technology that provides visibility and control over cloud applications (SaaS) used by users and devices. It uses API connections or inline proxies to inspect and enforce policies on data and activities in cloud applications, such as data loss prevention, threat protection, or compliance. Distributed Denial of Service Protection (DDoS) and Unified Threat Management (UTM) are not technologies that SASE combines into its unified platform, although they may be related or integrated with some of its components.

質問 # 41
You want to block access to sites that use self-signed certificates. Which statement is true in this scenario?
- A. Self-signed certificates must be changed to a publicly trusted CA signed certificate.
- B. Certificate-related settings apply to each individual client configuration level.
- C. Certificate-related settings apply globally to the entire customer tenant.
- D. Certificate-related settings apply to each individual steering configuration level.
正解：D
解説：
Explanation
The statement that is true in this scenario is: Certificate-related settings apply to each individual steering configuration level. Certificate-related settings are the options that allow you to configure how Netskope handles SSL/TLS certificates for encrypted web traffic. For example, you can choose whether to allow or block self-signed certificates, expired certificates, revoked certificates, etc. You can also choose whether to enable SSL decryption for specific domains or categories. Certificate-related settings apply to each individual steering configuration level, which means that you can have different settings for different types of traffic or devices. For example, you can have one steering configuration for managed devices and another one for unmanaged devices, and apply different certificate-related settings for each one. This allows you to customize your security policies based on your needs and preferences. References: Netskope SSL DecryptionNetskope Steering Configuration
質問 # 42
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. Traffic with pinned certificates should be blocked.
- C. The domains used by certificate-pinned applications should be added to the authentication bypass list.
- D. The domains used by applications with pinned certificates should be allowed in an inline policy.
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.

質問 # 43
You need to provide a quick view under the Skope IT Applications page showing only risky shadow IT cloud applications being used.
In this scenario, which two filter combinations would you use to accomplish this task? (Choose two.)
- A. CCL = High. Under Research
- B. Sanctioned = No
- C. User Device Type = Windows Device
- D. CCL = Medium. Low, Poor
正解：B、D
解説：
Explanation
To provide a quick view under the Skope IT Applications page showing only risky shadow IT cloud applications being used, you can use two filter combinations: Sanctioned = No and CCL = Medium, Low, Poor. The Sanctioned filter allows you to select whether you want to see only sanctioned or unsanctioned apps in your organization. Sanctioned apps are those that are approved and managed by your IT department, while unsanctioned apps are those that are used without authorization or oversight by your employees. Shadow IT refers to the use ofunsanctioned apps that may pose security or compliance risks for your organization. The CCL filter allows you to select the Cloud Confidence Level (CCL) ratings of the apps you want to see. The CCL rating is a measure of how enterprise-ready a cloud app is based on various criteria such as security, auditability, business continuity, etc. The CCL rating ranges from Excellent to Poor, with Excellent being the most secure and compliant and Poor being the least. Risky cloud apps are those that have a low CCL rating, such as Medium, Low, or Poor. By applying these two filters, you can narrow down the list of apps to only those that are unsanctioned and have a low CCL rating, which indicates that they are risky shadow IT cloud applications being used in your organization.

質問 # 44
What is a benefit that Netskope instance awareness provides?
- A. It prevents the user from copying information from a corporate email and pasting the information into a GitHub repository.
- B. It differentiates between an IT managed Google Drive instance versus a personal Google Drive instance.
- C. It differentiates between an IT managed Google Drive instance versus a personal Dropbox account.
- D. It prevents movement of corporate sensitive data to a personal Dropbox account.
正解：B
解説：
Explanation
A benefit that Netskope instance awareness provides is that it differentiates between an IT managed Google Drive instance versus a personal Google Drive instance. Instance awareness 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 instance for your IT managed Google Drive instance (such as drive.google.com/a/yourcompany.com) and another 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 instance. This can help you prevent data leakage, enforce compliance, or improve visibility for your cloud application activities. Preventing movement of corporate sensitive data to a personal Dropbox account, preventing the user from copying information from a corporate email and pasting it into a GitHub repository, or differentiating between an IT managed Google Drive instance versus an IT managed Box instance are not benefits that Netskope instance awareness provides, as they are either unrelated or irrelevant to the instance awareness feature. References: Netskope Security Cloud Operation & Administration (NSCO&A) - Classroom Course, Module 5: Real-Time Policies, Lesson 4: App Instances.
質問 # 45
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 website is used for domain registration.
- C. The domain contains malicious algorithms.
- 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 # 46
Why would you want to define an App Instance?
- A. to differentiate between an enterprise Google Drive instance vs. a personal Google Drive instance
- B. to enable the instance_id attribute in the advanced search field when using query mode
- C. to differentiate between an enterprise Google Drive instance vs. an enterprise Box instance
- D. to create an API Data Protection Policy for a personal Box instance
正解：A
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.

In this scenario, which two CCI aspects in the Ul would be used in a real-time protection policy? (Choose two.)
- A. GDPR Readiness
- B. App Tag
- C. CCL
- D. App Score
正解：B、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 # 52
You have applied a DLP Profile to block all Personally Identifiable Information data uploads to Microsoft 365 OneDrive. DLP Alerts are not displayed and no OneDrive-related activities are displayed in the Skope IT App Events table.
In this scenario, what are two possible reasons for this issue? (Choose two.)
- A. A Netskope POP is not in your local country and therefore DLP policies cannot be applied.
- B. The Cloud Storage category is in the Steering Configuration as an exception.
- C. The destination domain is excluded from decryption in the decryption policy.
- D. DLP policies do not apply when using IPsec as a steering option.
正解：B、C
解説：
Explanation
If the Cloud Storage category is in the Steering Configuration as an exception, then Netskope will not steer any traffic to or from cloud storage applications, such as Microsoft 365 OneDrive, to its platform. This means that Netskope will not be able to inspect or apply any policies to this traffic, including DLP policies. Similarly, if the destination domain is excluded from decryption in the decryption policy, then Netskope will not decrypt any traffic to or from that domain, such as onedrive.com. This means that Netskope will not be able to inspect or apply any policies to this traffic, including DLP policies. The location of the Netskope POP or the use of IPsec as a steering option do not affect the application of DLP policies, as long as Netskope can steer and decrypt the relevant traffic.
