   In a Virtual Chassis Fabric, what happens if one of the member switches fails?

   • AThe entire fabric shuts down to prevent loops
   • BOnly the failed switch's ports are disabled, but the fabric control plane stops
   • CThe fabric continues to operate, and traffic is rerouted through other members
   • DAll traffic is dropped until the switch is replaced

   A service provider is deploying EVPN-VXLAN in their data center. They have a pair of leaf switches that need to provide multihomed connectivity to a server, ensuring that if one leaf fails, the server remains connected. They want to use a single logical link from the server to both leaves. Which technology should they use?

   • AUse an ESI LAG, assigning the same Ethernet Segment Identifier to both links from the server to the two leaf switches.
   • BConfigure a standard LAG on the server with both links connected to the same leaf switch.
   • CUse a Virtual Chassis to combine the two leaf switches and then configure a regular LAG from the server to the virtual chassis.
   • DConnect the server to a single leaf and rely on VXLAN to provide redundancy.

   A data center is using EVPN-VXLAN with a pair of leaf switches providing multihomed connectivity to a server via ESI LAG. The server is connected with two links, one to each leaf. The network team wants to ensure that if one leaf fails, the server can still send and receive traffic. They also want to avoid any manual configuration changes on the server. Which statement is true about ESI LAG in this scenario?

   • AThe server must run a routing protocol to detect the leaf failure and reroute traffic.
   • BThe server must be configured with a different IP address for each leaf to ensure connectivity.
   • CThe two leaf switches must be configured with different Ethernet Segment Identifiers for the same server.
   • DThe ESI LAG allows the server to use a single logical link, and the leaves coordinate to provide redundancy without requiring changes on the server.

   In a Juniper EVPN-VXLAN environment, how does an ESI LAG typically load-balance traffic across the multihomed links?

   • ABased on the source MAC address only
   • BBased on the round-robin scheduling of packets
   • CBased on a hash of packet headers, such as MAC and IP addresses
   • DBased on the priority of the VLAN tags

   What is the primary purpose of an Ethernet Segment Identifier (ESI) in an ESI LAG?

   • ATo uniquely identify a multihomed Ethernet segment shared by multiple PE devices
   • BTo assign a unique MAC address to each physical link in the LAG
   • CTo provide a routing protocol for the EVPN-VXLAN fabric
   • DTo encrypt traffic between the CE and PE devices
