NSK300 Practice Questions

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.

Reference: The deployment methods and their suitability for isolated server subnets are based on

Netskope’s documentation and resources, which detail various deployment options and their use

cases21.

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. Reference:

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.

Reference: 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.

To ensure that the Netskope Client is always up-to-date with the latest upgrades, two actions are

required. First, in the Client Configuration, the administrator should set the option to Upgrade Client

Automatically to Latest Release. This setting ensures that the client will automatically update to the

most recent version available. Second, during the original installation of the Netskope Client,

the autoupdate-on flag should be set. This flag enables the auto-update feature, allowing the client

to receive and apply updates as they are released.

Reference: The information is based on the Netskope Client deployment options and upgrade

process as detailed in the Netskope Knowledge Portal

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.

Reference: The

for these answers can be found in the Netskope Knowledge Portal, which

provides detailed guidance on configuring and validating GRE tunnels12. Additionally, the Netskope

Community Forum offers insights and solutions for deploying and monitoring GRE tunnels

In the scenario where users are unable to access an application through Netskope Private Access,

and after verifying that the Real-time Protection policy allows access, the application is steered for

the users, and it is reachable from internal machines, the next step is to verify the application’s

reachability through the Netskope Publisher. The two tools in the Netskope UI that would be used to

accomplish this task are:

A . Reachability Via Publisher in the App Definitions page - This tool allows you to check if the

application is reachable through the configured Publishers. It is essential to ensure that the

application’s connectivity is intact and that there are no issues with the Publishers themselves.

B . Troubleshooter tool in the App Definitions page - The Troubleshooter tool can help diagnose and

resolve issues related to application reachability. It provides insights into potential problems and

offers guidance on how to fix them.

These tools are designed to assist in troubleshooting and ensuring that applications are accessible

through Netskope Private Access.

Reference: The explanation is based on the standard procedures for managing private applications

and troubleshooting within the Netskope Private Access environment as outlined in the Netskope

Knowledge Portal

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. Reference:

In the given scenario, a user is attempting to upload a file containing sensitive PII and PCI data to

Microsoft OneDrive. The Netskope Security Cloud provides real-time data and threat protection

when accessing cloud services, websites, and private apps from anywhere, on any device. Based on

the exhibit provided, different DLP (Data Loss Prevention) profiles are triggered - DLP-SourceCode,

DLP-PCI, and DLP-PII. Each of these profiles has specific actions associated with them; for instance, an

alert is generated for Source Code while blocking actions are initiated for PCI and PII data. Since

multiple DLP profiles are triggered due to the sensitive nature of the content in the file being

uploaded, separate incidents will be generated for each matching profile ensuring comprehensive

security coverage and incident reporting.

To address the issue of a certificate-pinned application not being accessible due to certificate

pinning, while still steering the traffic to Netskope, the two methods that would satisfy the

requirements are:

B: Configure the SSL Do Not Decrypt policy to not decrypt traffic for domains used by the native

application. This ensures that the SSL traffic for the specified domains is not decrypted, thus avoiding

issues with certificate pinning.

C: Configure domain exceptions in the steering configuration for the domains used by the native

application. By setting domain exceptions, traffic to these domains will bypass SSL decryption,

allowing the certificate-pinned application to function as expected1.

These methods are in line with Netskope’s capabilities for handling certificate-pinned applications,

which often require bypassing decryption to prevent breaking the application’s functionality due to

its security features1.

Reference: The Netskope Knowledge Portal provides detailed information on managing certificate-

pinned applications, including how to configure SSL Do Not Decrypt policies and domain exceptions

in the steering configuration1. Additionally, the Netskope Community Forum offers insights and best

practices for handling certificate-pinned applications2.

When using IPsec tunnels, especially in the context of deploying Netskope for on-premises devices,

several factors must be considered to ensure a secure and efficient architecture:

Cipher support on tunnel-initiating devices (A): It is crucial to ensure that the devices initiating the

IPsec tunnels support the ciphers used by Netskope. This compatibility is necessary for establishing

secure connections.

Bandwidth considerations (B): The bandwidth available for the IPsec tunnels will affect the data

throughput and performance of the connection. Adequate bandwidth must be allocated to handle

the expected traffic without causing bottlenecks.

The impact of threat scanning performance (D): The performance of threat scanning can be affected

by the encryption and decryption processes in IPsec tunnels. It is important to consider how the

threat scanning capabilities will perform under the additional load of encrypted traffic.

These elements are essential for the successful implementation of IPsec tunnels in a Netskope

architecture plan for on-premises devices12.

Reference: The considerations for using IPsec tunnels are outlined in the Netskope Knowledge Portal

and Community discussions, which provide guidance on deployment and validation of IPsec tunnels,

including cipher support, bandwidth management, and maintaining threat scanning performance
