Designing Cisco Enterprise Networks (ENSLD) — Question 181

An engineer is designing a campus network with Cisco Catalyst 9500 switches in the aggregation layer. The design requires running nonblocking Layer 2 MEC from the aggregation layer to the access layer. The Catalyst switches are located on different campus floors for availability reasons, and each access switch will contain a single VLAN. Which technology must the engineer choose for the aggregation switches in the design?

Answer options

Correct answer: D

Explanation

The correct choice is D, StackWise Virtual, as it allows for nonblocking Layer 2 MEC and provides high availability across multiple switches. Option A, VSS, is not suitable for Layer 2 MEC in this context, while B, StackWise-480, is a stacking technology that doesn't support the required configuration. Option C, VPC, is used in different scenarios primarily with Nexus switches, making it inappropriate for this setup.
