Exam 350-801 topic 1 question 339 discussion

Wording stuff: question looks not asking to do SRTP, but to configure.In the related link https://www.cisco.com/c/en/us/support/docs/unified-communications/telepresence-video-communication-server-vcs/118877-config-vcs-00.html#anc12 , there is only None, Mandatory and Best Effort. So only apply what matched the answers. Typical Cisco questions ;-)

It must say "Media Encryption Options" Reference: "Secure RTP between CUCM and VCS or Expressway Configuration Example" https://www.cisco.com/c/en/us/support/docs/unified-communications/telepresence-video-communication-server-vcs/118877-config-vcs-00.html#anc12

Media Encryption Options None Mandatory Best effort

https://www.cisco.com/c/en/us/support/docs/unified-communications/telepresence-video-communication-server-vcs/118877-config-vcs-00.html#anc12 Media Encryption Options None Mandatory Best effort

D,E is correct https://www.cisco.com/c/en/us/support/docs/unified-communications/telepresence-video-communication-server-vcs/118877-config-vcs-00.html#anc12

D and E. Mandatory, none, and "Best effort"

The final answer is D (mandatory) and A (optional). These are the two appropriate media encryption options when configuring SRTP between Cisco Unified Communications Manager (UCM) and Cisco VCS Expressway. It is important to use encryption whenever possible to ensure the security and integrity of the communication, and mandatory and optional are the recommended options in this context. Option E, "none," is not an appropriate media encryption option when configuring SRTP between these two systems.

D and E
