What is the purpose of the 'lacp rate fast' command on a Cisco Nexus switch?

To increase the number of LACP member ports allowed in an EtherChannel

To enable LACP to use a higher bandwidth for data transmission

To reduce the LACP packet transmission interval to 1 second for faster failure detection

To configure LACP to use a shorter timeout for the peer switch

A data center design includes two Nexus switches as a vPC pair. Downstream access switches connect to both peers using LACP. The design also uses RSTP+ in the L2 domain. The engineer wants to ensure that the vPC peer-link does not become a spanning-tree blocking point and that the downstream switches see a loop-free topology. Which statement about this design is true?

The downstream switches must be configured as spanning-tree root to avoid blocking.

The vPC peer-link is treated as a single logical link by RSTP+, so it does not block.

RSTP+ must be disabled on the vPC peer-link to prevent blocking.

LACP must be configured on the vPC peer-link to ensure it is not blocked.
