Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 85

An engineer is deploying Mobile and Remote Access to allow external Cisco Jabber users to sign into a Cisco UCM cluster via Cisco Expressways. The users will sign-in in the format[email protected]. Contact photos for Jabber are hosted on a webserver with the FQDN of phonebook cisco.com. Which configuration must be completed to allow external Jabber users to see contact photos?

Answer options

• A. An HTTP allow list entry must be made on the Expressway-E for phonebook cisco.com.
• B. A SIP allow list entry must be made on the Expressway-E for .*@cisco.com.
• C. An HTTP allow list entry must be made on the Expressway-C for phonebook cisco.com.
• D. A SIP allow list entry must be made on the Expressway-C for .*@cisco.com.

Correct answer: C

Explanation

The correct answer is C because contact photos are accessed via HTTP requests, which must be allowed on the Expressway-C where the internal resources are located. Options A and B incorrectly reference the Expressway-E, which handles external requests, while D incorrectly applies a SIP configuration rather than an HTTP configuration for the contact photos.
