You are using IBGP to deploy an IP fabric. There are four spine devices, two of which are configured as route reflectors. You notice that the other two spines are not receiving all the possible paths to each leaf, and traffic cannot be load-balanced to the leaf devices.
Which two actions will resolve this problem? (Choose two.)

• A.Configure the add-path parameter on the leaf devices.
• B.Configure the multipath parameter on the route reflectors.
• C.Configure the add-path parameter on the route reflectors.
• D.Configure the multihop parameter on the route reflectors.

You are deploying MC-LAG as shown in the exhibit.
Which statement is correct when using active/standby mode?

• A.Only ICCP control traffic is allowed through the ICL-PL connection.
• B.VCCP is used to exchange MAC addresses between MC-LAG peers.
• C.All traffic from Server A to Host 1 will traverse the link between Server A and ex2.
• D.A spanning tree protocol should be used to avoid Layer 2 loops between Server A and both switches.

Which statement is correct about EVPN Type 2 routers?

• A.An EVPN Type 2 route provides local proxy-arp for remote hosts.
• B.An EVPN Type 2 route allows data plane-based host MAC learning.
• C.An EVPN Type 2 route prevents the need to advertise host IP reachability.
• D.An EVPN Type 2 route disables MAC flowing to remote hosts.

You are deploying a VXLAN using EVPN signaling overlay network.
PE1 and PE2 are multihomed to the connected CE device.
You notice that the traffic is not load-balancing as expected.
Referring to the exhibit, which two actions will solve this problem? (Choose two.)

• A.Set the route distinguisher on PE2 to 11.11.11.11:100.
• B.Set the ESI on PE2 to 00:11:11:11:11:11:11:11:11:11.
• C.Set the LACP system ID on PE2 to 00:00:00:00:00:01.
• D.Set the ESI on both devices to 00:00:00:00:00:00:00:00:00:00.

In a preprovisioned mixed Virtual Chassis, which statement is correct about converting a 40Gbps QSFP+ to a Virtual Chassis port in an EX4300?

• A.One end of the link is configured as a Virtual Chassis port.
• B.LLDP is enabled on that interface.
• C.LLDP is disabled on that interface.
• D.Both ends of the link have the default configuration.
