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

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

In the exhibit, PE2 is receiving an EVPN auto-discovery (A-D) route from PEI. Based on the output, which of the following statements is FALSE?

• A.This route indicates that the EVPN service is configured on PEI with an EVPN instance (EVI) of 113.
• B.This route indicates that the EVPN service configured on PEI is multi-homed.
• C.This route is an A-D per EVPN instance (A-D per EVI) route advertised by PEI for a VPWS.
• D.This route indicates that the EVPN service is configured on PEI with a service MTU of 1514.

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.When PEI learns MAC-01, it advertises a MAC/IP route which indicates that MAC-OI is associated with ESI I.
• C.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.
• D.PE3 advertises an A-D per ES route which indicates that ESI I is operating in a single-active redundancy mode.
