Free Updated Cisco 300-610 Actual Exam Questions - Question 6 Discussion
Refer to the exhibit. An engineer is creating a new data center design for a customer. The design
must support virtual applications, enhance network resilience, and meet these requirements:
• Extend Layer 2 across all network segments to support endpoint mobility.
• Access switches will support up to 20 GB capacity for north-south and east-west traffic.
• Provide fast convergence during link failures.
• MAC address advertisement will not depend on the control plane.
Which solution must the engineer include in the design between the access and distribution
switches?
vPC usually depends on control plane for MAC sync, so it might not meet the MAC advertisement rule here. That makes A less likely; D seems closer but BGP-EVPN in B better fits all requirements. B
Maybe D could work because DVSTB (Distributed Virtual STP) helps with fast convergence and Layer 2 extension without heavy control plane dependency, which seems to match the requirements well.
I’m thinking about A (vPC) because it provides Layer 2 extension and fast failover, but it does rely on control plane for MAC sync. So does that conflict with the MAC advertisement requirement? Could that rule vPC out?
B imo, BGP-EVPN handles MAC advertisement efficiently without relying on the control plane.
A imo, vPC fits best for fast convergence and L2 extension.
