NSK300 Netskope Certified Cloud Security Architect Exam Questions and Answers

To validate that the GRE tunnel is configured correctly and that traffic is flowing to Netskope, the correct statements are:

A: You can use your local router or network device to verify that keepalives are being received and traffic is flowing to Netskope. This is a standard method for checking the health and activity of a GRE tunnel.

C: You can verify that the tunnel is up and receiving traffic in the Netskope UI under Settings > Security Cloud Platform > GRE. This is a feature provided by Netskope to monitor the status of GRE tunnels directly from the Netskope interface12.

Statement B is incorrect because Netskope provides its own tools for monitoring the status of the tunnel. Statement D is incorrect because the Netskope Trust portal provides information on the overall service status and updates, not specific tunnel status3.

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 to allow 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.

To ensure that the web application using HTTPS on port 6443 is both reachable and decrypted by Netskope, the correct action is to enable “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 inconsistent results observed during User Acceptance Testing (where marketing users sometimes access gambling sites and sometimes are blocked) are likely due to the configuration of the Forward Proxy.

Cookie Surrogate: The Cookie Surrogate is a mechanism used in Forward Proxy deployments to maintain user context across multiple requests. It ensures that user-specific policies are consistently applied even when multiple users share the same IP address (common in VDI environments).

Issue: If the Forward Proxy is not configured to use the Cookie Surrogate, it may lead to inconsistent behavior. When different users log into the VDI server, their requests may not be associated with their specific user context, resulting in varying policy enforcement.

Solution: Ensure that the Forward Proxy is properly configured to use the Cookie Surrogate, allowing consistent policy enforcement based on individual user identities. References:

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.

A. Import the root certificate for your internal certificate authority into Netskope:

This step ensures that Netskope recognizes and trusts SSL certificates issued by your company’s internal certificate authority. By importing the root certificate, you enable proper SSL inspection and validation for internal sites.

B. Bypass SSL inspection for the affected site(s):

Since the intranet site uses your company’s internal certificate authority, bypassing SSL inspection for this specific site allows users to access it without encountering SSL errors.

D. Change the SSL Error Settings from Block to Bypass in the Netskope tenant:

Adjusting the SSL Error Settings to “Bypass” allows users to proceed past SSL errors, including self-signed certificate errors. This ensures uninterrupted access to the intranet site. References:

When a user is on-premises at the enterprise and accesses an application that is IP restricted, the source IP for traffic to this application is the Enterprise Egress IPv4 address.

The Enterprise Egress IP represents the external IP address of the enterprise network as seen by external services or applications.

This IP address is used for communication between the user’s device and external resources, including applications that are IP restricted. References:

The answer is based on general knowledge of networking concepts and how IP addresses are used in enterprise environments.

The appropriate rule type to use in the DLP profile for a document that is considered confidential when filled out is fingerprint 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.

To verify the previous value of a structured data field in Salesforce after an unauthorized change, you would use Skope IT with an Access Method of API Connector. This method allows you to search the Application Event Details for the ‘Old Value’ field. By filtering with the user details and the edit activity, you can pinpoint the exact change and retrieve the original value of the field.

The Fast Scan component of Netskope Threat Detection utilizes Machine Learning to quickly detect and block malware in real-time. This is part of Netskope’s multi-layered security approach, which includes various engines to defend against a wide range of threats. The Fast Scan capability specifically leverages machine learning-based detection for rapid analysis and response to potential threats1.

To accomplish the task of not steering specific domains to the Netskope Cloud while using the Explicit Proxy over Tunnel (EPoT) steering method, you would define exception domains in the PAC file (A). This is because the PAC file is used to specify which domains should bypass the proxy and connect directly, thus allowing for granular control over the traffic that is steered to Netskope1.

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.
