   In an OS10 VLT environment, what is the role of spanning tree protocol (STP) on the VLT interconnect (peer link)?

   • ASTP treats the VLT interconnect as a normal link and may block it if it detects a loop.
   • BSTP uses the VLT interconnect to elect the root bridge for the VLT domain.
   • CSTP blocks the VLT interconnect to prevent loops between the peers.
   • DSTP does not run on the VLT interconnect; it is excluded from STP calculations.

   An administrator is troubleshooting a VLT deployment on OS10 switches. The 'show vlt' command shows that the VLT domain is up, but the 'show vlt statistics' command shows a high number of dropped packets on the VLT interconnect. The backup link is up. What is the most likely cause of the dropped packets?

   • AThe VLT LAG is misconfigured, causing traffic to be sent to the wrong peer.
   • BThe spanning-tree protocol is blocking the VLT interconnect.
   • CThe backup link is carrying too much traffic.
   • DThe VLT interconnect is oversubscribed, causing congestion and drops.

   A data center has two OS10 switches configured as VLT peers. The VLT interconnect is a 40GbE link, and the backup link is a 1GbE management link. The network team notices that when the interconnect fails, the VLT domain enters a dual-active state and the secondary switch disables its VLT LAG ports. However, they want to ensure that if the interconnect fails, the secondary switch does not disable its VLT LAG ports, but instead continues to forward traffic. What is the most appropriate action?

   • AConfigure the VLT domain to use the backup link as the primary failover mechanism and disable the dual-active detection.
   • BThis behavior is by design; the secondary switch must disable its VLT LAG ports to prevent a loop.
   • CConfigure the VLT LAG ports as edge ports to prevent them from being disabled.
   • DIncrease the VLT interconnect bandwidth to ensure it is more reliable.

   An organization is implementing VLT on two OS10 switches. They have configured the VLT domain, interconnect, and backup link. Now they need to configure a VLT LAG to connect to a downstream switch. What must be consistent between the two VLT peers for the VLT LAG to operate correctly?

   • AThe downstream switch must be configured with a different LAG ID than the VLT peers.
   • BThe LAG ID must be different on each peer to avoid conflicts.
   • CThe VLT interconnect must be a 10GbE link for the LAG to work.
   • DThe LAG ID and the port-channel mode must be the same on both peers.
