Which of the following statements about an EVPN with integrated routing and bridging (EVPN-IRB) service is FALSE?

• A.In this service, the IRB interface acts as a default gateway for hosts in the corresponding subnet.
• B.This service consists of a VPRN and multiple VPLSs.
• C.This service requires the use of EVPN-MPLS for data plane.
• D.This service enables the use of EVPN to provide connectivity between hosts in different subnets.

Which of the following statements about EVPN Layer-3 services that utilize the interface-ful model is TRUE?

• A.Intra-subnet traffic is carried over the tunnels provided by the SBD VPLS.
• B.EVPN MAC/IP routes are used to advertise the IP prefixes of subnets attached to a VPRN.
• C.VPRN instances are interconnected using a supplementary broadcast domain (SBD) VPLS.
• D.The MAC/IP routing information is used to populate the VPRN routing table at the remote PEs.

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

• A.Auto-discovery (A-D) routes are imported by all PES participating in the EVPN service.
• B.ES routes provide the ESI label required to support the split-horizon mechanism.
• C.Ethernet segment (ES) routes indicate the redundancy mode of the Ethernet segment.
• D.A-D per Ethernet segment routes indicate the desired designated forwarder election algorithm.

Examine the exhibit.

Which of the following actions is performed by PEI after it receives a BUM packet from CEI?

• A.PEI sends the packet to PE2 and to PE3. An ESI label is included only in the packet sent to PE3.
• B.PEI sends the packet to PE2 but not to PE3 because PE3 is connected to the originating ES.
• C.PEI does not flood the packet because PEI is acting as non-designated forwarder (non-DF) for VPLS 10.
• D.PEI sends the packet to PE2 and to PE3. An ESI label is included only in the packet sent to PE2.

In the exhibit,

VPLS 20 is associated with a single-active Ethernet segment on routers PEI and PE3. Which of the following statementsis FALSE?

• A.PEI advertises an A-D per ES route which indicates that ESI 1 is operating in a single-active redundancy mode.
• B.PEI advertises an A-D per EVI route which includes a P flag set to I to indicate that PEI is the DF for EVI 20.
• C.When PEI learns MAC-01, it advertises a MAC/IP route which indicates that MAC-OI is associated with ESI I.
• D.PE3 advertises an A-D per ES route which indicates that ESI I is operating in a single-active redundancy mode.
