Nutanix Certified Services – Core v6.8 (NCS-Core) — Question 12

After installation, network ports are properly configured with the default active-backup bonding. One 10GbE port goes to switch 1. Another 10GbE port goes to switch 2.
A consultant tests failover by manually disconnecting one of the cables and notices it is taking too much time to failover, which is causing excessive packet loss.
What should be enabled to resolve this issue?

Answer options

• A. LACP on switch
• B. PagP
• C. Spanning-tree Portfast
• D. Jumbo frames

Correct answer: C

Explanation

Enabling Spanning-tree Portfast allows ports to transition to the forwarding state more quickly, reducing failover time and minimizing packet loss during a disconnection. LACP and PagP are not suitable in this context as they deal with link aggregation rather than rapid failover. Jumbo frames, while beneficial for performance, do not address the failover delay issue directly.
