   What is the primary purpose of an MLAG (Multi-chassis Link Aggregation Group) in a campus network?

   • ATo enable routing between VLANs on different switches without a routing protocol
   • BTo create a single broadcast domain across multiple switches using VLAN trunking
   • CTo provide redundancy and increased bandwidth by allowing a downstream device to connect to two different switches as if they were one
   • DTo combine multiple physical links into a single logical link between two switches

   A company is designing an active-active access layer for its campus network. They want to connect end-user PCs with dual-homed NICs to two access switches. The goal is to provide redundancy and double the available bandwidth for each PC. Which MLAG use case does this scenario represent?

   • ACore redundancy, where the MLAG pair connects to the core layer.
   • BServer redundancy, where the MLAG pair connects to a server with dual NICs.
   • CSwitch redundancy, where the MLAG pair provides a redundant gateway for the access layer.
   • DActive-active access layer design, where end devices are dual-homed to the MLAG pair.

   You are designing an MLAG solution for a data center. The peer-link is a 40GbE link, and the keepalive link is a 1GbE link. During a maintenance window, you need to upgrade the firmware on one of the two switches. You want to minimize downtime. What is the BEST approach?

   • AUpgrade the peer-link first, then upgrade the switches.
   • BUpgrade one switch at a time, using the MLAG pair to maintain connectivity during the upgrade.
   • CUpgrade both switches simultaneously to ensure they run the same firmware version.
   • DDisable MLAG before the upgrade and re-enable it after both switches are upgraded.

   A network administrator wants to provide redundancy for a critical server that has two 10GbE NICs. The server team wants to use LACP to bundle the NICs. The administrator has two Dell switches that support MLAG. What is the PRIMARY benefit of using MLAG in this scenario compared to connecting each NIC to a separate switch without MLAG?

   • AMLAG simplifies the server's network configuration by removing the need for VLANs.
   • BMLAG allows both server NICs to be active simultaneously, providing increased bandwidth and redundancy.
   • CMLAG provides a redundant default gateway for the server.
   • DMLAG eliminates the need for LACP on the server.

   A campus network has two top-of-rack switches connecting to a storage array with dual active-active controllers. The storage team requires both controllers to be active simultaneously and wants to avoid any failover delay if one switch fails. The switches support MLAG. What should you configure to meet the storage team's requirement?

   • AUse a spanning-tree design with one link active and one in blocking state to prevent loops.
   • BConfigure a single LACP bundle from each storage controller to a different switch, relying on the storage multipath driver for failover.
   • CCreate an MLAG between the two switches and connect each storage controller with a single link to the MLAG pair, using LACP on the storage side.
   • DConnect each storage controller to a dedicated switch and configure VLT on the storage array, not on the switches.
