Measure (B): This field type would provide the weight of the links between the nodes, representing the number of objects or the risk score associated with each application1.
These two field types are essential for creating a Sankey visualization as they define the structure and flow of data between different stages or categories within the visualization.

質問 # 43
Review the exhibit.

You installed Directory Importer and configured it to import specific groups ot users into your Netskope tenant as shown in the exhibit. One hour after a new user has been added to the domain, the user still has not been provisioned to Netskope.
What are three potential reasons for this failure? (Choose three.)

• A. Directory Importer does not support ongoing user syncs; you must manually provision the user.
• B. The server that the Directory Importer is installed on is unable to reach Netskope's add-on endpomt.
• C. The user is not a member of the group specified as a filter
• D. The default collection interval is 180 minutes, therefore a sync may not have run yet.
• E. Active Directory integration is not enabled on your tenant.

正解：B、C、D

解説：
The three potential reasons for the failure of a new user not being provisioned to Netskope an hour after being added to the domain could be:
B . The server that the Directory Importer is installed on is unable to reach Netskope's add-on endpoint: If the server cannot connect to Netskope's endpoint, it cannot sync the user data. This could be due to network issues, incorrect configuration, or firewall restrictions1.
C . The user is not a member of the group specified as a filter: The Directory Importer may be configured to import users from specific groups only. If the new user is not a member of these groups, they will not be imported into Netskope1.
E . The default collection interval is 180 minutes, therefore a sync may not have run yet: The Directory Importer may be scheduled to sync every 180 minutes. If only an hour has passed, the sync process might not have occurred yet, and the user would not be provisioned until the next sync interval1.

Review the exhibit.

You created an SSL decryption policy to bypass the inspection of financial and accounting Web categories. However, you still see banking websites being inspected.
Referring to the exhibit, what are two possible causes of this behavior? (Choose two.)

• A. An incorrect category has been selected
• B. The policy is in a "disabled" state.
• C. An incorrect action has been specified.
• D. The policy is in a "pending changes" state.

正解：A、C

解説：
The issue described in the exhibit is that banking websites are still being inspected despite creating an SSL decryption policy to bypass the inspection of financial and accounting web categories.
Possible Causes:
An incorrect category has been selected (Option B):
If the SSL decryption policy is configured to bypass the wrong category (e.g., not the actual financial and accounting category), it won't effectively exclude banking websites from inspection.
An incorrect action has been specified (Option D):
If the action specified in the policy is not set to "Bypass," it won't achieve the desired behavior. The policy should explicitly bypass SSL inspection for the selected category.
Solution:
Verify that the correct category (financial and accounting) is selected in the policy, and ensure that the action is set to "Bypass."

質問 # 47
You are implementing a solution to deploy Netskope for machine traffic in an AWS account across multiple VPCs. You want to deploy the least amount of tunnels while providing connectivity for all VPCs.
How would you accomplish this task?

• A. Use IPsec tunnels from the AWS Virtual Private Gateway.
• B. Use IPsec tunnels from the AWS Transit Gateway.
• C. Use GRE tunnels from the AWS Virtual Private Gateway
• D. Use GRE tunnels from the AWS Transit Gateway.

正解：B

解説：
The best approach to deploy Netskope for machine traffic across multiple VPCs in an AWS account with the least amount of tunnels while providing connectivity for all VPCs is to use IPsec tunnels from the AWS Transit Gateway. This method allows you to use the same Site-to-Site VPN connection to Netskope for multiple VPCs, thus minimizing the number of tunnels required12. The AWS Transit Gateway acts as a network transit hub, enabling you to connect your VPCs and on-premises networks through a central point of management and control. Using IPsec tunnels with the AWS Transit Gateway ensures that all VPCs connected to it utilize the same IPsec tunnel between the transit gateway and Netskope POP1.

質問 # 48
Your company has a large number of medical forms that are allowed to exit the company when they are blank. If the forms contain sensitive data, the forms must not leave any company data centers, managed devices, or approved cloud environments. You want to create DLP rules for these forms.
Which first step should you take to protect these forms?

• A. Use Netskope Secure Forwarder to create EDM hashes of all forms.
• B. Use Netskope Secure Forwarder to create fingerprints of all forms.
• C. Use Netskope Secure Forwarder to create an MIP tag for all forms.
• D. Use Netskope Secure Forwarder to create an ML Model of all forms

正解：B

解説：
The first step to protect the medical forms containing sensitive data is to create fingerprints of all forms using Netskope Secure Forwarder. Fingerprints are unique identifiers that can be used to detect when a form contains sensitive data. By creating fingerprints, you can set up DLP (Data Loss Prevention) rules that will allow blank forms to exit the company but will prevent forms with sensitive data from leaving the protected environments. This method ensures that only forms without sensitive information are allowed to be shared externally.

質問 # 49
You recently began deploying Netskope at your company. You are steering all traffic, but you discover that the Real-time Protection policies you created to protect Microsoft OneDrive are not being enforced.
Which default setting in the Ul would you change to solve this problem?

• A. Remove the default steering exception for Cloud Storage.
• B. Disable the default Microsoft appsuite SSL rule.
• C. Disable the default certificate-pinned application
• D. Remove the default steering exception for domains.

正解：D

解説：
When deploying Netskope and steering all traffic, if you find that the Real-time Protection policies for Microsoft OneDrive are not being enforced, the likely issue is with the default steering exceptions. To resolve this, you should remove the default steering exception for domains . This is because the default exceptions may include domains related to Microsoft services, which could prevent the Real-time Protection policies from being applied to traffic directed towards OneDrive. By removing these exceptions, you ensure that all traffic, including that to OneDrive, is subject to the policies you have set up.

質問 # 50
You are attempting to merge two Advanced Analytics reports with DLP incidents: Report A with 3000 rows and Report B with 6000 rows. Once merged, you notice that the merged report is missing a significant number of rows.
What is causing this behavior?

• A. Visualizations have a system limit of 5000 rows.
• B. Netskope automatically deduplicates data in merged reports.
• C. Filters are applied differently to dimensions and measures
• D. Missing data is due to viewing limits.

正解：D

解説：
When merging two Advanced Analytics reports in Netskope, if the merged report is missing rows, it is likely due to viewing limits within the system. Netskope's Advanced Analytics platform has limitations on the number of rows that can be viewed at once, which can result in missing data when dealing with large reports. This viewing limit ensures performance and manageability of the data within the system.

Users at your company's branch office in San Francisco report that their clients are connecting, but websites and SaaS applications are slow When troubleshooting, you notice that the users are connected to a Netskope data plane in New York where your company's headquarters is located.
What is a valid reason for this behavior?

• A. The Netskope Client's default DNS over HTTPS call is failing.
• B. The Netskope Client's DNS call to Secure Forwarder is failing
• C. The Netskope Client's on-premises detection check failed.
• D. The closest Netskope data plane to San Francisco is unavailable.

正解：D

解説：
The reported issue of slow website and SaaS application access for users in the San Francisco branch office, despite being connected to a Netskope data plane in New York, can be attributed to the geographical distance between the user location and the data plane. The Netskope Security Cloud operates through a distributed network of data planes strategically placed in various regions. When users connect to a data plane that is geographically distant, it can result in latency due to longer network traversal times. In this case, the closest Netskope data plane to San Francisco might be unavailable or experiencing high load, leading to performance issues. To address this, consider optimizing data plane selection based on proximity to the user location or investigating any data plane availability or performance issues.

質問 # 52
A company's architecture includes a server subnet that is logically isolated from the rest of the network with no Internet access, no default gateway, and no access to DNS. New resources can only be provisioned on virtual resources in that segment and there is a firewall that is tunnel-capable securing the perimeter of the segment. The only requirement is to have content filtering for any server that might access the Internet using a browser.
Which two Netskope deployment methods would achieve this requirement? (Choose two.)

• A. Install the Netskope Client on the servers
• B. Deploy a mobile profile on the servers.
• C. Deploy IPsec or GRE tunnels in the segment to steer traffic from the servers to Netskope.
• D. Deploy Data Plane on Premises (DPoP) with a proxy configuration on the servers.

正解：C、D

解説：
For a server subnet that is isolated and requires content filtering for any server that might access the Internet using a browser, the two Netskope deployment methods that would meet this requirement are:
B . Deploy Data Plane on Premises (DPoP) with a proxy configuration on the servers: Deploying DPoP would allow the isolated servers to connect to the Netskope cloud for content filtering through a proxy configuration. This setup would enable the servers to have controlled access to the Internet for content filtering purposes without requiring direct Internet access1.
C . Deploy IPsec or GRE tunnels in the segment to steer traffic from the servers to Netskope: By deploying IPsec or GRE tunnels, the traffic from the servers can be securely directed to Netskope for content filtering. This method is suitable for environments where servers do not have direct Internet access, as the tunnel provides a secure path for traffic to reach Netskope's cloud services1.
These deployment methods are designed to work in environments with strict network isolation and provide the necessary content filtering capabilities for servers accessing the Internet.
