350-601 Question #64: Real Exam Question with Answer & Explanation

Question

Which two statements about the process at upgrading an EPLD on a Cisco MDS 9000 Series Switch are correct? (Choose two.)

Options

• AEPLDs can be upgraded only to the latest EPLD image.
• BEPLD upgrades can be completed without powering down the module during the upgrade.
• CAn upgrade verification identifies the impact of each EPLD upgrade.
• DThe EPLDs for all the modules on a switch must be upgraded at the same time.
• EEPLDs can be upgraded without replacing the hardware.

Explanation

When you upgrade or downgrade the EPLDs, observe the following guidelines and limitations: - You can upgrade each module only when it is online. The EPLD upgrade is only disruptive to the module being upgraded. - If you interrupt an EPLD upgrade or downgrade, the module must be upgraded again. - In Cisco MDS 9000 Director Switches, EPLD upgrade or downgrade can only be executed from the active supervisor module. To upgrade the supervisor EPLDs nondisruptively, upgrade the standby supervisor and then switchover. After the new standby supervisor is online, its EPLDs can be upgraded. - In Cisco MDS 9000 Series Fabric Switches, be sure to specify 1 as the module number. The switch must be power cycled for the EPLDs to start running the new code.
