   An engineer is explaining VLT to a colleague. They need to describe the role of the VLT interconnect (peer link) in OS10. What is the primary function of the VLT interconnect?

   • AIt connects the VLT peers to the downstream switch.
   • BIt is used only for management traffic.
   • CIt provides a backup path for the VLT backup link.
   • DIt carries control traffic and data traffic between the VLT peers.

   A VLT domain is configured on two OS10 switches. One of the switches fails completely. What happens to the VLT LAGs and the downstream traffic?

   • AThe surviving switch continues to forward traffic through the VLT LAGs, and the failed switch's ports are no longer used.
   • BThe downstream switch must be reconfigured to use a single link.
   • CThe surviving switch reboots to re-establish the VLT domain.
   • DAll VLT LAGs go down until the failed switch is replaced.

   A network engineer is configuring VLT on a pair of OS10 switches that also run spanning tree protocol (STP). The VLT LAG connects to a downstream switch. How does STP interact with the VLT LAG to prevent loops?

   • ASTP treats the VLT LAG as a single logical port, and the VLT peers coordinate to present a consistent STP state.
   • BSTP runs independently on each VLT peer, and the downstream switch sees two separate STP paths.
   • CSTP is disabled on all VLT ports, and loop prevention is handled solely by the VLT interconnect.
   • DSTP uses the VLT backup link to communicate BPDUs between peers.

   How does OS10 VLT interact with spanning tree protocol (STP) to prevent loops in the network?

   • AVLT peers appear as a single STP bridge, so STP does not block the VLT LAG ports.
   • BVLT runs a separate instance of STP on each peer to avoid loops.
   • CVLT uses STP to elect a root bridge among the VLT peers.
   • DVLT disables STP on all ports to avoid blocking VLT LAGs.
