Free Cisco 300-730 SVPN Actual Exam Questions - Question 3 Discussion

Option D, since DTLS reduces latency by using UDP instead of TCP for the VPN tunnel.

Maybe D. Enabling DTLS often helps with audio delays because it switches the VPN traffic to UDP, which is better for real-time communication like voice. A and B seem less relevant since 3DES is slower and shorter key lifetimes mainly affect security, not latency. Installing AnyConnect 2.3 (C) feels outdated and probably not the fix here unless the question mentioned version issues. So enabling DTLS is the usual go-to for improving call quality over VPNs by reducing delay.

B might help because shorter key lifetimes can reduce the chance of stale encryption slowing down the connection, which could improve call responsiveness without needing protocol changes.

Not A, because 3DES is outdated and slower, so switching to it wouldn't reduce delay. D looks better since DTLS handles real-time audio traffic more efficiently by using UDP instead of TCP.

Option D, DTLS reduces latency by handling real-time traffic better than TCP.

It’s B. Shortening the encryption key lifetime can help maintain a more secure and responsive connection, which might reduce delays during audio calls.

D, DTLS usually helps with audio/video latency over VPN.
