An engineer is preparing to install a new line card in a Nexus switch. The switch is running a recent NX-OS version, but the line card requires an EPLD update. What is the primary purpose of the EPLD update?

To ensure the line card is compatible with the switch hardware.

To fix a bug in the line card's firmware.

To add new features to the switch.

To upgrade the NX-OS software on the switch.

A data center has a pair of Nexus 9000 switches in a vPC domain. The engineer needs to upgrade the NX-OS software on both switches. The maintenance window is limited, and the network must remain available for critical traffic. Which approach should the engineer take?

Upgrade both switches simultaneously during the maintenance window, accepting a brief total outage.

Upgrade one switch, verify it, then upgrade the second switch while the first carries traffic.

Upgrade the secondary switch first, then the primary, but do not verify the first upgrade before starting the second.

Upgrade the primary switch, then immediately upgrade the secondary switch in the same maintenance window.

A data center has a single Nexus switch that cannot be taken out of service during business hours. The engineer needs to apply a software update that requires a reload. What is the best approach?

Use ISSU to perform a nondisruptive upgrade.

Schedule the update during a maintenance window outside business hours.

Apply the update without a reload to avoid downtime.

Apply the update during business hours and accept the brief outage.

A data center has a pair of Nexus switches in a vPC domain. The engineer needs to upgrade the software and also update the EPLD on both switches. The upgrade is disruptive, and the EPLD update also requires a reload. The maintenance window is limited. What is the best sequence to minimize downtime?

Upgrade NX-OS and EPLD on one switch, verify, then do the same on the second switch.

Perform EPLD updates on both switches first, then upgrade NX-OS on both.

Upgrade NX-OS on both switches simultaneously, then perform EPLD updates simultaneously.

Upgrade NX-OS on both switches first, then perform EPLD updates on both.

In which scenario is an EPLD update most likely required?

When installing a new line card that requires a hardware logic update for compatibility.

When adding a new VLAN to the switch.

When upgrading the switch's software to a new minor release.

When changing the switch's hostname.
