   What is the function of the peer keepalive in an MLAG domain on Dell PowerSwitch?

   • AIt is used to synchronize the MAC address tables between the two switches
   • BIt carries data traffic between the two MLAG switches when the peer link fails
   • CIt is a separate link used to detect whether the peer switch is still operational
   • DIt is used to elect the primary switch in the MLAG domain

   A network engineer is configuring an MLAG domain on two Dell PowerSwitch switches. Which of the following is a mandatory prerequisite for the MLAG configuration to work?

   • AThe peer link must be configured as a port-channel with at least one physical link.
   • BBoth switches must be in the same VLAN for the peer keepalive link.
   • CThe MLAG domain ID must be the same as the VLAN ID used for management.
   • DThe two switches must be stacked together using a stacking cable.

   An administrator notices that the MLAG peer link is down on one of the switches. The switch logs show that the peer keepalive is still being received. What should the administrator check first to diagnose the issue?

   • ACheck the keepalive link configuration and ensure it is using the correct source IP.
   • BCheck the MLAG domain ID configuration on both switches.
   • CCheck the STP state of the peer link ports.
   • DCheck the status of the physical ports that make up the peer link port-channel.

   How does MLAG prevent loops when Spanning Tree Protocol (STP) is enabled on the switches?

   • AMLAG disables STP on all ports to avoid conflicts
   • BMLAG uses a separate loop prevention protocol instead of STP
   • CSTP is run only on the peer link, not on MLAG ports
   • DThe two MLAG switches appear as a single bridge to STP, so the MLAG ports are treated as one logical link

   A campus network team is deploying two Dell PowerSwitch switches as an MLAG pair to provide redundancy for access switches. They plan to connect the two switches using a 40GbE link and configure a keepalive interface. Which statement correctly describes the purpose of the peer link and the keepalive link in this design?

   • AThe peer link and keepalive link are redundant paths for the same purpose, and either can be used to forward data traffic.
   • BThe peer link is used to synchronize MAC and routing tables, while the keepalive link is used to forward broadcast traffic between the switches.
   • CThe peer link carries data traffic between the MLAG switches, while the keepalive link is used only to detect a peer failure.
   • DThe peer link is used only for control-plane synchronization, and the keepalive link carries all data traffic between the MLAG switches.
