vPC+ Feature Selection for VXLAN Multipod Design
Short answer
A The engineer must select vPC+ to support the VXLAN multipod design connecting traditional vPC domains to the fabric.
Question
Key Takeaways
The exam tests the distinction between standard vPC and vPC+, specifically highlighting that vPC+ is designed for interconnecting with ACI or VXLAN fabrics where the switch acts as a vPC peer.
This question evaluates the correct vPC variant for connecting traditional server clusters to a VXLAN EVPN fabric, establishing that vPC+ is the required feature.
Common mistake: Candidates often choose 'enhanced vPC' or 'double-sided vPC' due to terminology confusion, failing to recognize that vPC+ is the specific term for Fabric Extender-like connectivity in Nexus 9000 VXLAN deployments.
Expert Analysis
Why the Answer Is Correct
The correct answer is A (vPC+) because the design involves a VXLAN multipod architecture. In Cisco Nexus 9000 Series switches running NX-OS, vPC+ is the feature that allows a traditional vPC domain to connect to an ACI fabric or a VXLAN EVPN fabric where the upstream device acts as a virtual peer. It simplifies the configuration by eliminating the need for manual peer-link and peer-switch configurations typically found in standard vPC, making it ideal for the described optimal Layer 3 transport scenario.
Why the Other Options Are Wrong
Option B (single-sided vPC) is not a standard Cisco term for this high-redundancy active/active requirement. Option C (enhanced vPC) usually refers to feature enhancements like LACP load balancing but does not inherently support the VXLAN fabric integration described. Option D (double-sided vPC) is also not a standard feature name; while the topology might be double-sided physically, the logical feature enabling this specific VXLAN integration is vPC+.
Community Comment Notes
Community feedback strongly supports vPC+. One user noted that 'VPC+ is appropriate to connect the traditional vPC to Fabric vPC,' which aligns with the official documentation regarding VXLAN multipod designs. Another user debated between vPC+ and other options but ultimately acknowledged the specific use case for vPC+ in fabric integrations.
Exam Strategy
When designing for VXLAN multipod or ACI integration, always look for 'vPC+' as the solution for connecting traditional data center servers. Remember that vPC+ abstracts the peer-link complexity, allowing the fabric to manage the redundancy automatically.
