   What is the primary purpose of Virtual Link Trunking (VLT) in a Dell PowerSwitch data center deployment?

   • ATo aggregate multiple physical links into a single logical link between two switches
   • BTo enable a downstream device to form a port-channel with two upstream switches, providing redundancy and increased bandwidth
   • CTo replace Spanning Tree Protocol entirely by using a mesh of links between all switches
   • DTo provide a single control plane for multiple switches in a stack

   What is the purpose of the VLT backup link?

   • ATo send keepalive messages between the VLT peers to detect if a peer is alive
   • BTo carry data traffic between the VLT peers when the VLTi is congested
   • CTo provide a redundant path for management traffic to the VLT peers
   • DTo connect the VLT peers to the downstream devices

   A data center is deploying a pair of Dell PowerSwitch switches as a VLT pair to connect multiple servers using LACP. The goal is to provide active-active load balancing and redundancy for the server links. Which benefit does VLT provide in this scenario?

   • AAllows both switches to forward traffic for the same LAG, eliminating the need for STP to block one link
   • BEliminates the need for a backup link because the VLTi provides keepalive
   • CRequires only one switch to be active at a time, with the other in standby
   • DProvides a single point of failure for the server links

   Which requirement must be met for the VLT interconnect (VLTi) to function correctly?

   • AIt must be a single physical link between the two VLT peers
   • BIt must be a Layer 3 routed link with an IP address on each end
   • CIt must be a dedicated link that is not used for any other traffic
   • DIt must be configured as a port-channel with at least one physical link

   A network engineer is designing a VLT deployment with two Dell PowerSwitch switches. The VLT interconnect (VLTi) will be used to carry both control-plane traffic (e.g., VLT keepalive and LACP) and data-plane traffic between the peers. The engineer wants to ensure that the VLTi does not become a loop in the L2 topology. Which statement about the VLTi is correct?

   • AThe VLTi must be a routed link with OSPF to prevent loops
   • BThe VLTi is excluded from spanning-tree calculations and is never blocked, even if a loop is detected
   • CThe VLTi requires a separate VLAN for data traffic to avoid loops
   • DThe VLTi is a normal port-channel that participates in spanning-tree and can be blocked if a loop is detected
