PCNSE · Question #855
Which configuration change will improve network reliability and ensure minimal disruption during tunnel failures?
The correct answer is B. Set up a backup tunnel and reduce the tunnel monitoring interval and threshold to detect failures. For IPsec VPN reliability, Option B enhances failover speed by adding a backup tunnel and tuning tunnel monitoring. Reducing the interval (e.g., to 2 seconds) and threshold (e.g., to 3 retries) ensures quick detection and failover to the backup tunnel, minimizing disruption.
