Exam 300-820 topic 1 question 106 discussion

A seems correct. The statement says routing is in place for URIs without a port, only A correctly strips the port so that the resulting URI can be routed.

It's "A" The question is saying "do not expect" a port. It's saying to strip the port off the end. So A is the correct one

The correct configuration to allow routing of calls with a port number of 5060 at the end of the URI would be: D. * transform with a pattern string of “(.*)@example.com(:5060)?" replace a string of \[email protected]\2 This configuration uses a regular expression to capture the URI with or without the port number (:5060). Then, it replaces it with the captured part (\[email protected]) and appends the port number (\2), if present, ensuring that the call routing accommodates URIs with or without the port number specified.
