Question

Refer to the exhibit. A network engineer is implementing a configuration checkpoint on a Cisco Nexus 9000 Series Switch. The configuration must skip any existing vPC configuration errors and must complete if there are any configuration errors. The engineer finished the vPC domain configuration part. Which command completes the checkpoint implementation?

Options

  • Astop-at-first-failure
  • Batomic
  • Cbest-effort
  • Dverbose

Why each option

To implement a configuration checkpoint on a Cisco Nexus 9000 Series Switch that completes even if vPC configuration errors exist, the best-effort option must be used.

Astop-at-first-failure

stop-at-first-failure would halt the configuration process upon encountering the first error, contradicting the requirement to complete despite errors.

Batomic

The atomic keyword would treat the entire configuration as a single transaction, rolling back all changes if any part fails, which also contradicts the requirement to complete if errors exist.

Cbest-effortCorrect

The best-effort keyword, when used with configuration checkpoints or commits on Cisco Nexus switches, ensures that the system attempts to apply as much of the configuration as possible, even if certain parts, like vPC configurations, encounter errors. This fulfills the requirement to skip errors and complete the checkpoint despite failures.

Dverbose

The verbose keyword only affects the level of detail in the command output and does not control how errors are handled during the configuration process.
