Exam 300-430 topic 1 question 67 discussion

Actual exam question from Cisco's 300-430

Question #: 67
Topic #: 1

A Cisco CMX 3375 appliance on the 10.6.1 version code counts duplicate client entries, which creates wrong location analytics. The issue is primarily from iOS clients with the private MAC address feature enabled. Enabling this feature requires an upgrade of the Cisco CMX 3375 appliance in a high availability pair to version 10.6.3. SCP transfers the Cisco CMX image, but the upgrade script run fails. Which configuration change resolves this issue?

A. Upgrade the high availability pair to version 10.6.2 image first and then upgrade to version 10.6.3.
B. Save configuration and use the upgrade script to upgrade the high availability pair without breaking the high availability.
C. Break the high availability using the cmxha config disable command and upgrade the primary and secondary individuality.
D. Run root patch to first upgrade to version 10.6.2 and then migrate to version 10.6.3.

In CMX’s current format you have to disable HA in order to perform an upgrade. In order to disable HA from the command line, run cmxha config disable from the primary CMX
