   How is a VLT LAG formed between a VLT peer pair and an attached device?

   • AThe attached device connects to one VLT peer, and that peer forwards traffic to the other peer over the VLTi
   • BEach VLT peer creates its own independent port-channel to the attached device, and the two port-channels are connected via the VLTi
   • CThe attached device creates a port-channel that includes links to both VLT peers, and the peers coordinate to treat it as a single LAG
   • DThe VLT peers use the VLTi to create a single virtual switch, and the attached device connects to that virtual switch via a single link

   Which benefit does Virtual Link Trunking (VLT) provide in a data center network?

   • AIt simplifies management by combining two switches into a single logical device with one IP address
   • BIt provides a backup path for management traffic between switches using a dedicated link
   • CIt allows both uplinks from a server to be active, increasing available bandwidth and providing fast failover
   • DIt eliminates the need for any Spanning Tree Protocol configuration on all switches in the network

   A network engineer is configuring a VLT pair and needs to ensure that the VLT interconnect (VLTi) can handle both control-plane and data-plane traffic. The engineer plans to use multiple physical links for the VLTi. What is the recommended way to configure the VLTi?

   • AConfigure the VLTi as a routed link with a /30 subnet
   • BUse a single physical link for the VLTi and rely on the backup link for redundancy
   • CUse a separate VLAN for the VLTi and disable STP on that VLAN
   • DCreate a port-channel with the physical links and assign it as the VLT interconnect

   In a VLT domain, the primary and secondary roles are important for certain operations, such as handling of BPDUs and management of the VLT domain. A network administrator wants to ensure that a specific switch becomes the primary VLT peer. Which configuration should be applied?

   • ASet a lower VLT domain priority on the desired switch
   • BConnect the backup link to the desired switch first
   • CConfigure the desired switch with a higher system MAC address
   • DSet a higher VLT domain priority on the desired switch

   A VLT pair is configured with a VLTi that is a port-channel of four 10GbE links. The backup link is a 1GbE link. The network administrator is concerned about the VLTi being a single point of failure. Which additional configuration can improve the resilience of the VLTi?

   • AAdd more physical links to the VLTi port-channel
   • BUse a single 40GbE link for the VLTi instead of four 10GbE links
   • CConfigure the backup link to carry data traffic as a fallback
   • DEnable spanning-tree on the VLTi to provide redundancy
