Refer to the exhibit. A network engineer plans to upgrade the current software images of a Cisco Nexus switch. What is the impact of starting the EPLD upgrade?

Question

Exhibit

Options

• AThe switch reboots multiple times for the new EPLD versions to take effect.
• BThe switch reboots one time for the new EPLD versions to take effect.
• CThe switch skips the EPLD upgrade for MIFPGA and proceeds with the other EPLD devices.
• DThe switch skips the EPLD upgrade for each EPLD device of the switch.

• A
  2% (1)
• B
  8% (5)
• C
  3% (2)
• D
  87% (53)

Explanation

EPLD (Electronic Programmable Logic Device) upgrades on Cisco Nexus switches check current EPLD versions before proceeding. When the exhibit shows that all EPLD devices on the switch are already running the latest versions (i.e., current version equals the upgrade version), the switch will skip the EPLD upgrade for each EPLD device rather than performing an unnecessary re-flash. This is a built-in safety mechanism that prevents redundant updates. Options A and B are incorrect because a reboot is only required when an EPLD actually needs upgrading. Option C is incorrect because there is no special logic to skip only MIFPGA while processing others.
