Cisco 300-815 Exam - Topic 7 Question 44 Discussion

The SIP session refresh timer allows the RTP session to stay active during an active call. The Cisco UCM sends either SIP-INVITE or SIP-UPDATE messages in a regular interval of time throughout the active duration of the call. During a troubleshooting session, the engineer finds that the Cisco UCM is sending SIP-UPDATE as the SIP session refresher, and the engineer would like to use SIP-INVITE as the session refresher. What configuration should be made in the Cisco UCM to achieve this?
C) Change Session Refresh Method on the SIP profile to INVITE.
A) Enable SIP ReMXX Options on the SIP profile.
B) Enable Send send-receive SDP in mid-call INVITE on the SIP profile.
D) Increase Retry INVITE to 20 seconds on the SIP profile.

A is also important for some setups, but C is definitely the main fix.

Wait, can you really switch it just like that? Seems too easy.

The /64 subnet mask seems like the obvious answer here. It's the default for IPv6 and should give us plenty of room to work with for the 10 subnets and 200 VMs per subnet.

I think the answer might be Symbolic Execution since it involves determining inputs that affect code paths, but I'm not entirely sure.

I'm a bit confused on this one. I know /etc/shadow has password information, but I'm not sure what the different values mean. I'll have to review my notes.

I'm a bit unsure about this one. The Script helper could potentially hold permission settings, automation version history, or timeout configuration, in addition to available commands. I'll need to think this through carefully before selecting an answer.
