2. Which of the following statements about the EVPN route types used to support multi-homing is TRUE?

Ethernet segment (ES) routes indicate the redundancy mode of the Ethernet segment.

ES routes provide the ESI label required to support the split-horizon mechanism.

Auto-discovery (A-D) routes are imported by all PES participating in the EVPN service.

A-D per Ethernet segment routes indicate the desired designated forwarder election algorithm.

3. Based upon the exhibit, which of the following statements is FALSE?

VPLS 10 must be configured with two BGP instances on PE3 and PE4.

On PE3 and PE4, VPLS 10 must be configured with two different route-distinguisher values: one for VXLAN and another for MPL

On PE3 and PE4, VPLS 10 must be configured with two different route-target values: one for VXLAN and another for MPL

A BGP export policy is required on PE3 and PE4 to ensure that IMET routes originated with VXLAN encapsulation are not advertised to the peer across the core network.

5. Based on the exhibit below, which of the following statements is FALSE?





When forwarding BUM traffic, the local PE must replicate the traffic and send it as unicast to the advertising neighbor.

9. Which of the following statements about EVPN auto-discovery per Ethernet segment (A-D per ES) routes is TRUE?

The updates include an Ethernet segment identifier label that is used in loop prevention.

The updates advertise the Ethernet segment availability in a given EVPN service.

The updates include an MPLS label that is set to a non-zero value.

The updates include an Ethernet tag ID that is set to zero.

11. Based upon the exhibit,





Which of the following statements about the forwarding of BUM traffic is FALSE?

PE3 replicates the traffic and sends it to all PES in its VPLS I flooding list.

PE3 adds an ESI label to packets forwarded to PEI because PEI is connected to the same Ethernet segment.

PEI forwards the traffic received from PE3 to CEI, and CEI discards it based upon the ESI label.
