Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 56

An administrator recently upgraded a Cisco Webex DX80 through its web interface but discovered the next morning that the unit has received to its previous version. What must the administrator do to prevent this from happening again?

Answer options

• A. Assign a phone security profile with secure SIP.
• B. Set the prepare cluster for rollback to pre-8.0 enterprise parameter to true.
• C. Confirm the phone load name in the phone configuration.
• D. Assign a universal device template to the phone.

Correct answer: C

Explanation

The correct answer is C because confirming the phone load name ensures that the correct firmware version is assigned to the device, preventing it from rolling back. Options A and D do not directly address the firmware versioning issue, while option B is related to rollback settings but does not ensure that the correct version is maintained.
