I believe we need to set up some sort of access control list, but I can’t remember the exact configuration steps for the Cisco UCM.

I’m a bit confused about the options. I think I need to recall the specific commands for allowing only SIP traffic.

This question feels similar to the practice scenarios we did last week. I think we had to configure SIP settings in one of them.

I remember we discussed toll fraud prevention in class, but I’m not sure if it was specifically about SIP connections.

I feel pretty confident about this one. Based on the details provided, it seems like the key is to configure the Cisco Unified Border Element to only allow SIP traffic, which would help prevent toll fraud. I'll carefully consider the options and select the one that best matches that requirement.

Okay, let's see here. The exhibit shows some network topology, but I'm not sure how that relates to the question. I'll need to really analyze the options and think through the best way to meet the stated requirements.

Hmm, I'm a bit unsure about this one. The question mentions toll fraud prevention, but doesn't give much detail on what that entails. I'll need to think carefully about the options and how they relate to the specific requirements.

This looks like a pretty straightforward question. I'll focus on the key details - the requirement to only allow SIP protocol through the Cisco Unified Border Element, and the need to implement toll fraud prevention on the Cisco UCM cluster.

Option A seems a bit too basic. Gotta go with Option B to really lock things down and prevent those pesky toll fraudsters.

I'm leaning towards Option C. Configuring SIP normalization and disabling unsecured RTP might be the best approach here.
