NSE 7 — Enterprise Firewall — Question 69

An administrator must optimize the performance of real-time voice and video applications across a WAN link with high packet loss.

Which combination of IPSec phase 1 parameters must the administrator configure to reduce errors and boost application reliability?

Answer options

• A. fec-ingress and fsc-egrsss
• B. dpd and dpd-retryinterval
• C. fragmentation and fragmentation-mtu
• D. keepalive and keylive

Correct answer: A

Explanation

The correct choice, A, involves configuring fec-ingress and fsc-egrsss, which are crucial for Forward Error Correction, thus improving the reliability of real-time applications over lossy links. Options B and D relate to monitoring and maintaining connections but do not directly address packet loss, while option C, fragmentation, is more about handling packet sizes rather than enhancing reliability.
