In a data center design that uses vPC, what is the role of Spanning Tree Protocol (STP) on the vPC peer switches?

STP is still required to prevent loops in the topology, but vPC presents a single logical switch to downstream devices

STP is replaced by vPC, so no spanning-tree configuration is needed

STP is only needed on the peer-link, not on other ports

STP is disabled on vPC peer switches because vPC eliminates all loops

What is the purpose of the peer-keepalive link in a Virtual Port Channel (vPC) setup?

To synchronize the MAC address tables between vPC peers

To carry data traffic between the vPC peers

To monitor the health of the vPC peer switches and detect a peer failure

To provide a backup path for the vPC member ports

What is the primary role of Link Aggregation Control Protocol (LACP) in a data center network?

To enable fast convergence of routing protocols

To provide encryption and authentication for data in transit

To negotiate and manage the bundling of multiple physical links into a single logical link

To provide a loop-free topology at Layer 2

An engineer is configuring vPC on a pair of Nexus 9000 switches. The engineer has already configured the vPC domain, peer-keepalive link, and peer-link. The engineer now needs to add a downstream switch that will connect to both peers using a port-channel. Which step is required to complete the vPC configuration for this downstream connection?

Create a port-channel on each peer and configure it as a vPC member with the same vPC ID.

Configure the downstream switch with LACP active mode and connect it to only one peer.

Enable RSTP+ on the peer-link and configure the downstream switch as the root bridge.

Configure the downstream switch with a single link to one peer only.

Which command configures the peer-keepalive link to use interface mgmt0 and destination IP 10.1.1.2 in a vPC domain?

peer-keepalive destination 10.1.1.2 source mgmt0

peer-keepalive ip 10.1.1.2 interface mgmt0

keepalive destination 10.1.1.2 source mgmt0

vpc peer-keepalive destination 10.1.1.2 source mgmt0
