Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 128

The EPLD update of the supervisor module has been scheduled for several Cisco MDS 9000 Series Switches. What will be the impact of the update?

Answer options

• A. All traffic is stopped for the duration of the EPLD update and the switch is rebooted after the upgrade is completed.
• B. The redundant supervisor takes over while the EPLD update is in progress and the switch is rebooted after the upgrade is completed.
• C. All control plane traffic is stopped for the duration of the EPLD update and the switch remains operational for the duration of the upgrade.
• D. The redundant supervisor takes over while the EPLD update is in progress and there is no service disruption.

Correct answer: A

Explanation

The correct answer is A because during the EPLD update, all traffic is temporarily halted and the switch must reboot once the update is complete. Options B, C, and D incorrectly suggest that the switch remains operational or that a redundant supervisor can maintain service, which is not the case during this specific update process.
