Designing Cisco Data Center Infrastructure (DCID) — Question 189

An engineer deploys VMware ESXi hypervisor on blade servers. The virtual networking is managed by Cisco Nexus 1000V Series Switches.

Which configuration aligns with Cisco recommended practices for providing high availability and a maximum throughput to the VMware ESXi hosts?

Answer options

• A. dual vNICs with static EtherChannel link aggregation
• B. dual vNICs with hardware fabric failover on the fabric interconnects
• C. dual vNICs with MAC pinning link aggregation
• D. dual vNICs with LACP link aggregation

Correct answer: D

Explanation

The correct answer is D, dual vNICs with LACP link aggregation, as it is a dynamic method that provides load balancing and redundancy, aligning with Cisco's best practices for high availability. Options A and C use static and MAC pinning methods, which do not provide the same level of flexibility as LACP. Option B, while providing failover, does not ensure maximum throughput like LACP does.
