NSK300 Exam Questions & Answers

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.

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.

To enable the Netskope Client to automatically determine whether it is on-premises or off-premises, you can use the following options in the Netskope UI:

Enable Dynamic Steering:

This option is available in theSteering Configurationsection of the UI.

By enabling dynamic steering, the Netskope Client can intelligently determine the appropriate data plane (on-premises or cloud) based on the user's location and network conditions.

It ensures that traffic is directed to the optimal data plane for improved performance and security.

On Premises Detection:

This option is available under theClient Configurationsection of the UI.

By configuring on-premises detection, the Netskope Client can identify whether it is connected to the local network (on-premises) or accessing resources from outside (off-premises).

It helps in applying relevant policies and steering traffic accordingly.

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.''

To prevent potential routing issues and ensure that the Netskope agent consistently sees the traffic first, it is recommended tomodify the VPN to operate in full tunnel mode at Layer 3.

In full tunnel mode, all traffic from the endpoint is routed through the VPN, including traffic destined for Netskope. This ensures that the Netskope agent can inspect and apply policies to all traffic, regardless of the destination.

Layer 3 full tunnel mode provides better visibility and control over the traffic flow, reducing the risk of routing conflicts or bypassing the Netskope inspection.Reference:

The answer is based on general knowledge of VPN configurations and their impact on traffic routing.
