300-610 Question #307: Real Exam Question with Answer & Explanation

The correct answer is C: Implement vPC link aggregation to increase overall bandwidth capacity and provide redundancy.. IEEE 802.1AX and 802.3ad define Link Aggregation and LACP. By configuring a vPC pair on Nexus switches and bundling member links into a LACP‑based EtherChannel, you both double (or more) the logical bandwidth and gain seamless hitless failover-resolving congestion and enhancing r

Question

A data center with high network-traffic demands is facing challenges related to link throughput, with recent reports of significant traffic congestion and performance degradation. To ensure optimal network performance and user experience, a network engineer implemented PFC and enabled jumbo frames on all network devices in the data center. However, the senior network architect requested further improvements to completely resolve the issue. The solution must follow IEEE 802.1 AX and IEEE 802.3ad principles. Which action must the network engineer take to accomplish the goal?

Options

  • AImplement upgraded 10GbE or 40GbE network links to increase bandwidth capacity.
  • BImplement HQoS to classify and prioritize traffic based on its criticality and bandwidth application
  • CImplement vPC link aggregation to increase overall bandwidth capacity and provide redundancy.
  • DImplement DCBXP with the ETS protocol to provide granular traffic management and bandwidth

Explanation

IEEE 802.1AX and 802.3ad define Link Aggregation and LACP. By configuring a vPC pair on Nexus switches and bundling member links into a LACP‑based EtherChannel, you both double (or more) the logical bandwidth and gain seamless hitless failover-resolving congestion and enhancing resilience per the IEEE specs.
