P-187

Refer to the exhibit. An engineer must implement toll fraud prevention on a Cisco UCM cluster. Only the SIP protocol
must be allowed for connections passing through Cisco Unified Border Element. What must be configured?

This one looks like D since configuring an inbound SIP ACL on the CUBE directly restricts protocols, matching the requirement to allow only SIP. It’s more precise than route groups here. D
It’s B for me too. Using standard local route groups is the straightforward way to keep the same route pattern but send calls out through the local gateway at each site. That way, the system automatically picks the right gateway based on the device’s location without messing with CSS or transforms. Options A and D seem more complex than needed here, and C isn’t about routing patterns—it’s about gateway permissions, which doesn’t solve the main issue.
Option B makes sense here since standard local route groups let you apply the same route pattern but direct calls locally based on the gateway assigned to each location. That fits the setup described.
A imo, because CSS alternate routing lets you define different routing behaviors for the same pattern, depending on the location. That fits the scenario better than just transforms.
Maybe D, transforms help modify route patterns per group. Makes sense here.
