Cisco Implementing Cisco Collaboration Hybrid and Cloud Technologies (CLHCT) v2.0 Sample Questions (Q53-Q58):

NEW QUESTION # 53
Which connection does the traversal zone configuration define?

A. Expressway-E and Collaboration Endpoints
B. Cisco UC and Cisco Unified Presence Server
C. Cisco Expressway-C and Cisco Expressway-E platforms
D. Cisco UCS E-Series and Cisco UCM

NEW QUESTION # 54
Which two statements about Mobile and Remote Access certificate are true? (Choose two.)

A. Expressway must generate certificate signing request.
B. Expressway Core can use private CA signed certificate.
C. You must upload the root certificates in the phone trust store.
D. Expressway Edge must use public CA signed certificate.
E. The Jabber client can work with public or private CA signed certificate.

Answer: B,D

Explanation:
Public vs. Private Certificate Authority (CA)
There are a number of options to sign certificates on the Expressway-C and E servers. You can opt to have the Certificate Signing Request (CSR) signed by a public CA such as GoDaddy, Verisign, or others, or you can sign it internally using your own Certificate Authority (CA) (can either be self signed using openSSL or an internal enterprise CA such as a Microsoft Windows server).
The only server that is really required to be signed by a public CA is the Expressway-E. This is the only server that clients will see the certificate from when singing in via MRA therefore using a public CA will ensure that users do not have to manually accept the certificate. Using an internal CA to sign the Expressway-E will work but first time users will be prompted to accept the untrusted certificate. MRA registration of 7800 and 8800 series phones also will not work with internal certificates because their certificate trust list cannot be modified. For simplicity it is suggested that your Expressway-C and Expressway-E certificates both be signed by the same CA however this is not a requirement as long as you properly configured the trusted CA lists on both servers.
