List of questions
Question 11

Based upon the exhibit, which of the following statements is FALSE?
PE1 does not use VXLAN tunnels to reach neighbors 10.10.10.2 and 10.10.10.3. PE1 uses MPLS tunnels to reach these neighbors, as indicated by the MPLS label values in the output.
Question 12

Proxy-ARP/ND is operational for a VPLS. Which of the following statements is FALSE?
When the PE learns a local host IP address, it does not add an entry into its proxy-ARP table. The proxy-ARP table is populated by snooping IP packets received from remote PEs. The PE advertises a MAC/IP route that includes the MAC and IP address of a local host.
Question 13

Based upon the exhibit, which of the following statements is FALSE?
VPLS 10 does not need to be configured with two BGP instances on PE3 and PE4. VPLS 10 can be configured with a single BGP instance that supports both VXLAN and MPLS encapsulations.
Question 14

Which of the following statements about an EVPN with integrated routing and bridging (EVPN-IRB) service is FALSE?
EVPN with integrated routing and bridging (EVPN-IRB) service does not require the use of EVPN-MPLS for data plane. EVPN-IRB service can use either EVPN-MPLS or EVPN-VXLAN for data plane.
Question 15

Which of the following statements does NOT describe the operation of the Layer-3 EVPN asymmetric forwarding model?
All VPLS instances do not need to be configured on all PEs regardless of whether they have a local host or not. Only the VPRN instance needs to be configured on all PEs, while the VPLS instances are configured only on PEs that have a local host attached to them.
Question 16

In the exhibit, the interface-less forwarding model is used for the Layer-3 EVPN service. Which of the following statements about traffic forwarding from Host 1 to Host 2 is FALSE?
PE1 does not encapsulate the packet with two labels: an outer transport label and an inner service label.PE1 encapsulates the packet with three labels: an outer transport label, a service label associated with VPRN 11, and a service label associated with RVPLS 11.

Question 17

The interface-ful numbered model is used for a Layer-3 EVPN service. Which of the following statements is FALSE?
EVPN MAC/IP routes are not used to advertise the MAC and IP addresses of SBD IRB interfaces.EVPN MAC/IP routes are used to advertise the MAC and IP addresses of local hosts attached to the SBD VPLS2.

Question 18

In the exhibit, the interface-ful numbered model is used for the Layer-3 EVPN service. Which of the following is used as the source MAC address in the packets sent from PEI when forwarding customer traffic to Host 2?
MAC-01 is used as the source MAC address in the packets sent from PE1 when forwarding customer traffic to Host 2.MAC-01 is the MAC address of the SBD IRB interface configured in VPRN 11 on PE12.

Question 19

A Layer-3 EVPN service is configured to use the interface-ful unnumbered forwarding model. Which of the following statements is FALSE?
The SBD IRB interface configured in the VPRN service has an IP address assigned to it.The IP address is used as a gateway IP address for hosts in the corresponding subnet2.

Question 20

An operator configures an EVPN-IRB that uses the interface-ful unnumbered forwarding model on a Nokia 7750 service router. Which of the following statements regarding the configuration performed on each participating PE is FALSE?
The advertisement of IP-Prefix routes is not enabled in the SBD VPLS.The advertisement of IP-Prefix routes is enabled in the VPRN service that is associated with the SBD VPLS2.
