   What role does a VLT LAG play in providing redundancy?

   • AIt ensures that Spanning Tree Protocol blocks one of the links to prevent loops
   • BIt provides a single point of failure for the attached device
   • CIt allows both links to be active, so if one switch fails, the other continues forwarding traffic without interruption
   • DIt provides a backup link that is used only when the primary link fails

   Which parameter is used to identify a VLT domain and must be the same on both VLT peers?

   • CVLT backup link IP address
   • DVLT system MAC address

   How does VLT interact with Spanning Tree Protocol (STP) to prevent loops?

   • AVLT uses STP to block one of the links in the VLT LAG to prevent loops
   • BVLT disables STP on all ports to prevent loops
   • CVLT presents the two peer switches as a single STP bridge, so STP does not block the VLT LAG
   • DVLT uses a separate protocol to replace STP entirely

   A server is connected to two Dell PowerSwitch switches that are configured as a VLT pair. The server uses a NIC teaming solution to create a single logical link to the switches. The team is configured in LACP mode. Which configuration on the switches is required to form a VLT LAG with the server?

   • ACreate a single port-channel on the primary switch and add the server-facing ports from both switches
   • BConfigure the server-facing ports as individual access ports and rely on STP to block one link
   • CUse a single physical link from the server to one switch and configure a static route to the other switch
   • DCreate a port-channel on each switch and add the server-facing ports, then configure the port-channel as a VLT LAG on both switches

   A VLT pair is configured with a VLTi and a backup link. The VLTi fails, and the backup link is operational. The network administrator notices that the VLT LAGs on the secondary peer are disabled. What is the most likely reason for this behavior?

   • ASTP blocked the VLT LAGs on the secondary peer because the VLTi is down
   • BThe secondary peer lost its VLT role election and is now in standby mode
   • CThe backup link is carrying data traffic and caused a loop
   • DThe secondary peer detected the VLTi failure via the backup link and disabled its VLT LAGs to prevent a split-brain scenario
