In a vPC architecture, what is the role of the peer-link?

To connect the vPC peers to the upstream network

To carry control traffic and data traffic between the vPC peers to synchronize state and forward traffic

To monitor the health of the vPC peer switches

To provide a backup path for the vPC member ports

A data center architect is designing a leaf-spine fabric with two Nexus 9000 leaf switches at the access layer. Each leaf connects to two spine switches. The architect wants to present a single logical L2 domain to downstream servers while ensuring fast convergence if one leaf fails. The servers will use dual-homed NICs with LACP. Which design decision best meets these requirements?

Configure the two leaf switches as separate spanning-tree roots and use LACP only between the spines.

Connect each server to only one leaf switch and rely on RSTP+ to converge if that leaf fails.

Use a single spanning-tree instance across the fabric and disable RSTP+ on all links.

Configure a vPC domain between the two leaf switches and use a vPC to connect the servers.

What is the primary purpose of Rapid Spanning Tree Protocol Plus (RSTP+) in a Cisco data center switching environment?

To provide a loop-free logical topology while enabling faster convergence than classic Spanning Tree Protocol

To aggregate multiple physical links into a single logical link for increased bandwidth

To provide redundancy at Layer 3 by allowing multiple equal-cost paths to a destination

To enable two switches to act as a single logical switch for downstream devices
