Netskope Exam NSK101 Topic 5 Question 37 Discussion

To monitor IPsec tunnels to a Netskope data plane, it is essential to ensure the stability and responsiveness of the tunnels. The recommended steps involve enabling monitoring mechanisms that detect and respond to tunnel failures. Here's a detailed explanation of the two recommended steps:

Enable IKE Dead Peer Detection (DPD) for each tunnel:

Implementation: Configure DPD in the IPsec settings of the perimeter device. This ensures that if the Netskope data plane is unreachable, the tunnel is automatically terminated and re-negotiated.

Send ICMP requests to the Netskope location's Probe IP:

Implementation: Set up regular ICMP requests (ping) from the perimeter device to the Netskope Probe IPs. This allows for continuous monitoring of the tunnel's health and immediate detection of connectivity issues.
