I vaguely recall that the client needs to trust the private CA certificate, so option D sounds familiar to me too.

I'm not entirely sure, but I feel like the Jabber client might need to register internally first, like in option B.

I think I saw a similar question where the device needed to trust a certificate. Could it be option D?

I remember something about certificates being crucial for secure connections, so maybe it's related to the CA certificate?

I'm not totally sure about this one. The question mentions Expressway-C and Expressway-E, so there might be some network configuration involved too. I'll have to review my notes on Expressway before deciding.

Okay, I think I've got it. The Jabber client needs to trust the private CA certificate, so the answer is D. The client has to download and trust that cert to be able to register.

Hmm, I'm a bit confused here. I know the certificates are the problem, but I'm not sure if the solution is to put the CA cert on the phone or have the client download it. I'll have to think this through carefully.

This one seems pretty straightforward. The issue is with the private certificates, so I'm guessing the answer is either A or D.

This is a good one. The key is recognizing that the issue is with the private certificates. I'd go with D - the client needs to download and trust the CA cert to be able to register successfully.

Hmm, I'm a bit unsure about this one. I know mysqli and PDO are both database interfaces, but I can't quite remember the specific differences. I'll have to think this through carefully.

Ah, the joys of playing 'Certificate Roulette' with Cisco devices. Gotta love it when you have to play 'Find the Secret CA' just to get a Jabber client to work. Where's the fun in using a public CA, right?

Ah, the old 'private CA certificate' problem. Classic Cisco exam question. Looks like the answer is to get that certificate on the device. Easy peasy, lemon squeezy!

Using a VPN? That's overkill for this problem. Plus, who wants to deal with the hassle of a VPN when you can just download the private CA certificate? Gotta keep it simple, you know?

Hmm, I don't think the Jabber client needs to register internally first. That's just adding an extra step. The key is to get the private CA certificate on the device, that should do the trick.

Ah, I see. The private CA certificate needs to be in the phone's trust store. Otherwise, the Jabber client won't trust the certificate and won't be able to register. Easy fix!
