   Why are EPLD updates typically considered disruptive?

   • AThey change the device's IP addressing scheme.

   A network engineer is planning to update the EPLD (Enhanced Programmable Logic Device) firmware on a Nexus 9000 switch that is currently carrying production traffic. The switch is a single unit (not part of a vPC or fabric). The engineer has a 15-minute maintenance window. What is the most important consideration before starting the EPLD update?

   • AThe EPLD update will require a full switch reload and will cause a traffic outage, so the maintenance window must accommodate the downtime.
   • BThe EPLD update is nondisruptive and can be performed during normal business hours without any traffic impact.
   • CThe EPLD update can be performed while the switch is forwarding traffic, but only if the switch is in a vPC pair.
   • DThe EPLD update is only needed if the switch is running an older NX-OS version and can be skipped if the version is current.

   Why is it important to schedule a disruptive update during a maintenance window?

   • ATo ensure the update completes faster.
   • BTo avoid the need for a configuration backup.
   • CTo allow the update to be performed remotely.
   • DTo minimize the impact of the expected traffic interruption.

   A network administrator is planning a software upgrade on a standalone Nexus 9000 switch that does not support ISSU for the target release. The switch is currently carrying production traffic for a hospital's patient-monitoring system. The administrator has a 1-hour maintenance window. What is the primary impact of this upgrade that must be communicated to the stakeholders?

   • AThe upgrade will be completely transparent to the network, and no downtime is expected.
   • BThe upgrade will only affect management traffic, not data traffic.
   • CThe upgrade will cause a brief traffic interruption, so the maintenance window must be scheduled during a period of low activity.
   • DThe upgrade will require a full configuration reload, but data traffic will continue to flow.

   A data center team is preparing to upgrade the NX-OS software on a pair of Nexus 9000 switches that are part of a vPC domain. The new release is known to be disruptive (no ISSU support). The team has a 4-hour maintenance window on a weekend. Which best practice should the team follow to minimize the risk of the upgrade?

   • AUpgrade the secondary switch first, then the primary, but do not verify the secondary after the upgrade.
   • BUpgrade both switches simultaneously to save time, since the maintenance window is long enough.
   • CUpgrade one switch at a time, verifying the first switch is stable and forwarding traffic before upgrading the second.
   • DUpgrade only one switch and leave the other on the old version to avoid any risk.
