Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 463

An engineer configures the properties of a Cisco UCS Cisco Integrated Management Controller network adapter for a standalone Cisco C-Series Server. The
Failback Timeout in the vNIC was set to 600. When the failure occurs, the secondary interfaces must be used and then failback when the primary interface becomes available again. Which action must be taken to meet these requirements?

Answer options

• A. Set default VLAN on the adapters.
• B. Increase CoS to 6.
• C. Enable Uplink Failover.
• D. Disable VNTAG mode.

Correct answer: C

Explanation

The correct answer is C, as enabling Uplink Failover allows the system to automatically switch to secondary interfaces during a failure and revert to the primary interface once it is available. The other options do not address the failover mechanism required to achieve the desired behavior of using secondary interfaces during a primary failure.
