質問 # 29
You are architecting a Netskope steering configuration for devices that are not owned by the organization The users could be either on-premises or off-premises and the architecture requires that traffic destined to the company's instance of Microsoft 365 be steered to Netskope for inspection.
How would you achieve this scenario from a steering perspective?
- A. Use explicit proxy and the Netskope Client
- B. Use reverse proxy.
- C. Use DPoP and Secure Forwarder
- D. Use IPsec and GRE tunnels.
正解：A
解説：
For devices not owned by the organization, using an explicit proxy along with the Netskope Client is the best approach to steer traffic for inspection. This method allows for granular control over the traffic, ensuring that only the traffic destined for the company's instance of Microsoft 365 is inspected by Netskope. The explicit proxy configuration can be applied regardless of whether the users are on-premises or off-premises, providing a consistent steering mechanism for all users.
質問 # 30
You built a number of DLP profiles for different sensitive data types. If a file contains any of this sensitive data, you want to take the most restrictive policy action but also create incident details for all matching profiles.
Which statement is correct in this scenario?
- A. Create a Real-time Protection policy for each DLP profile; each matched profile will generate a unique DLP incident.
- B. Create a single Real-time Protection policy and include all of the DLP profiles; all matched profiles will show up in a single DLP incident.
- C. Create a Real-time Protection policy for each DLP profile; all matched profiles will show up in a single DLP incident
- D. Create a single Real-time Protection policy and include all of the DLP profiles; each matched profile will generate a unique DLP incident
正解：B
解説：
When configuring a Real-time Protection policy with multiple DLP profiles, if the content matches multiple profiles, the policy performs the most restrictive action associated with the DLP profiles that match for that policy. The resulting incident lists all the profiles that matched along with their corresponding forensic information. This means that even though the most restrictive action is taken, details for all matching profiles are created and included in a single DLP incident12.
質問 # 31
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 DNS call to Secure Forwarder is failing
- B. The closest Netskope data plane to San Francisco is unavailable.
- C. The Netskope Client's on-premises detection check failed.
- D. The Netskope Client's default DNS over HTTPS call is failing.
正解：B
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 # 32
You have enabled CASB traffic steering using the Netskope Client, but have not yet enabled a Real-time Protection policy. What is the default behavior of the traffic in this scenario?
- A. Traffic will be allowed and logged.
- B. Traffic will be blocked and logged.
- C. Traffic will be blocked, but not logged.
- D. Traffic will be allowed, but not logged.
正解：A
解説：
In the scenario where CASB traffic steering is enabled using the Netskope Client without a Real-time Protection policy being activated, the default behavior of the traffic is toallow and log it (B). This means that the traffic will not be blocked; instead, it will be permitted to pass through and will be recorded for monitoring and analysis purposes.This default setting ensures visibility into the traffic and user activities without immediately enforcing a block, allowing for a period of observation and policy tuning before potentially more restrictive actions are taken1.
The default behavior of traffic steering in Netskope, including the logging of allowed traffic, is detailed in Netskope's best practices and community discussions on Real-time Protection policies1.
質問 # 33
Users in your network are attempting to reach a website that has a self-signed certificate using a GRE tunnel to Netskope. They are currently being blocked by Netskope with an SSL error. How would you allow this traffic?
- A. Ensure that the users add the self-signed certificate to their local certificate store.
- B. Configure a Real-time Protection policy with the action set to Allow.
- C. Set the No SNI setting in Netskope to Bypass.
- D. Configure a Do Not Decrypt SSL Decryption rule to allow traffic to pass.
正解：D
解説：
To allow traffic from a website with a self-signed certificate that is being blocked by Netskope with an SSL error, the correct action is to configure a Do Not Decrypt SSL Decryption rule. This rule will allow the traffic to pass without being decrypted, thus bypassing the SSL error caused by the self-signed certificate. This is a common practice for handling traffic from trusted internal applications or specific external sites that use self-signed certificates1.

質問 # 38
A hospital has a patient form that they share with their patients over Gmail. The blank form can be freely shared among anyone. However, if the form has any information filled out. the document is considered confidential.
Which rule type should be used in the DLP profile to match such a document?
- A. Use fingerprint classification.
- B. Use a dictionary rule for all your patient names.
- C. Use predefined DLP Rule(s) that match the patient name.
- D. Use Exact Match with patient names
正解：A
解説：
The appropriate rule type to use in the DLP profile for a document that is considered confidential when filled out isfingerprint classification. Fingerprinting is a method used to identify and protect sensitive data within documents. It works by creating a digital fingerprint of a file, which can then be used to detect any copies or derivatives of that file.In this case, fingerprinting would allow the hospital to differentiate between the blank patient form, which can be freely shared, and the same form with patient information filled out, which is confidential1.
Netskope's DLP rules can contain elements such as predefined data identifiers, custom data identifiers, keyword identifiers from a dictionary file, RegEx expressions, and exact match criteria1.For this specific use case, fingerprint classification is the most effective method as it can accurately detect the presence of filled- out information in the forms, which is crucial for maintaining patient confidentiality as per HIPAA regulations1.

You are asked to ensure that a Web application your company uses is both reachable and decrypted by Netskope. This application is served using HTTPS on port 6443. Netskope is configured with a default Cloud Firewall configuration and the steering configuration is set for All Traffic.
Which statement is correct in this scenario?
- A. Enable "Steer non-standard ports" in the steering configuration and create a corresponding Real-time Protection policy to allow the traffic
- B. Enable "Steer non-standard ports" in the steering configuration and add the domain and port as a new non-standard port
- C. Nothing is required since Netskope is steering all traffic.
- D. Create a Firewall App in Netskope along with the corresponding Real-time Protection policy to allow the traffic.
正解：B
解説：
To ensure that the web application using HTTPS on port 6443 is both reachable and decrypted by Netskope, the correct action is toenable "Steer non-standard ports" in the steering configuration and add the domain and port as a new non-standard port. This is because Netskope's default configuration steers standard HTTP
/HTTPS traffic, typically on ports 80 and 443.Since port 6443 is a non-standard port for HTTPS traffic, it requires explicit configuration to be steered through Netskope1.
The process for configuring non-standard ports in Netskope is detailed in the Netskope Knowledge Portal, which provides step-by-step instructions on how to steer HTTP(S) traffic over non-standard ports1. This includes adding the specific non-standard port number in the steering configuration to ensure that traffic to and from that port is properly handled by Netskope.
