B is the best answer, but the wording of the question and answer could be improved, since MRA isn't enabling CTI control via jabber; that already exists for onprem whether you have Expressway or not.

there is no VPN when it comes to MRA
B 2
Selected Answer: B
Worst question ever, typical Cisco trying to make questions "hard" and ending up just writing nonsense. Had to get that off my chest.
Anyway, that said:
A: MRA is not needed for internal endpoints to call other companies, that's B2B instead.
B: Only possible right answer. Jabber doesn't necessarily need MRA to use call control on CUCM, but it's the one that makes a little bit of sense.
C, D: The whole point of MRA is for clients to connect without using a VPN, so no.

Looks like C.. the rest are wrong

Not C.
MRA gives a secure connection for Jabber application traffic and other devices with the needed capabilities to communicate without having to connect to the corporate network over a VPN.
B is the correct answer:
MRA lets endpoints such as Cisco Jabber have their registration, call control, provisioning, messaging and presence services provided by Cisco Unified Communications Manager (Unified CM) when the endpoint is outside the enterprise network. The Expressway provides secure firewall traversal and line-side support for Unified CM registrations.

It's B.

Selected Answer: B
IT is B
A 1
Selected Answer: A
B doesn't require MRA and is possible internally with CUCM alone.
C is just false. MRA uses proxy secure firewall traversal and looks a bit like VPN functionality in some ways, but it's still NOT a VPN.
D... I don't even know what they're trying to say here. This just makes no sense.
Honestly, this question sucks. I'm almost inclined to say A because Expressway provides MRA which allows internal SIP calls to be routed from inside one organization, across an unsecure network to another (external) company using the B2B (Business to Business) methodology. Yes, it leaves some of the answer to the imagination, but the other answers just seem to much more wrong...
