Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 65

Which statement is true about upgrading the firmware on a Cisco MDS storage switch with dual supervisors?

Answer options

• A. Supervisors can be upgraded independently to test the new firmware.
• B. The new firmware is loaded on the standby supervisor first.
• C. Both supervisors load the new firmware and then the active supervisor reboots.
• D. The standby supervisor must be offline before the firmware upgrade begins.

Correct answer: B

Explanation

The correct answer is B because during the upgrade process, the new firmware is first loaded onto the standby supervisor to ensure that it is functioning correctly before the active supervisor is updated. Option A is incorrect because the upgrade is typically coordinated rather than independent. Option C is misleading as it suggests both supervisors load the firmware simultaneously, which is not the case. Option D is incorrect as the standby supervisor does not need to be offline before the upgrade begins.
