Question No. 1

What are EVPN inclusive multicast Ethernet tag (IMET) routes used for?

ATo advertise the MAC or MAC/IP addresses of locally-learned hosts

BTo advertise the redundancy mode of a local Ethernet segment

CTo discover all PES participating in the same VPIS service

DTo discover all PES attached to the same Ethernet segment

Show Answer

Correct Answer: C

EVPN inclusive multicast Ethernet tag (IMET) routes are used to discover all PEs participating in the same VPIS service. These routes are also used to build the flooding list for BUM traffic.

Question No. 2

Examine the exhibit.

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

APEI does not flood the packet because PEI is acting as non-designated forwarder (non-DF) for VPLS 10.

BPEI sends the packet to PE2 but not to PE3 because PE3 is connected to the originating ES.

CPEI sends the packet to PE2 and to PE3. An ESI label is included only in the packet sent to PE2.

DPEI sends the packet to PE2 and to PE3. An ESI label is included only in the packet sent to PE3.

Show Answer

Correct Answer: C

PE1 sends the packet to PE2 and to PE3. An ESI label is included only in the packet sent to PE2. The ESI label is used to implement the split-horizon mechanism and prevent traffic duplication. The packet sent to PE3 does not need an ESI label because PE3 is connected to the same Ethernet segment as PE1.

Question No. 3

In the exhibit, an EVI range is configured and the preference-based algorithm is used to elect the designated forwarder (DF) on ESI 1. Which PE is elected as DF for VPLS 10?

APEI

BPE2

CPE3

DPE4

Show Answer

Correct Answer: C

PE3 is elected as DF for VPLS 10. The preference-based algorithm uses the highest preference value of the PEs attached to the same Ethernet segment as the tie-breaker criterion. PE3 has the highest preference value among PE1, PE2, and PE3.

Question No. 4

Which of the following statements about the EVPN Layer 2 Attributes extended community is FALSE?

AIt is advertised with the auto-discovery per EVPN instance (A-D per EVI) route.

BIt is applicable to EVPN VPLS services.

CIt specifies the service maximum transmission unit (MTU).

DIt specifies a P flag that indicates whether the advertising PE is a primary PE.

Show Answer

Correct Answer: B

The EVPN Layer 2 Attributes extended community is not applicable to EVPN VPLS services.It is applicable to EVPN VPWS services, where it carries information such as the tag ID and the service MTU1.

Question No. 5

Examine the exhibit.

Which of the following configuration conditions is required for the proper operation of EVPN VPWS 2?

AThe local AC tag ID configured on PE2 must match the local AC tag ID configured on PEI.

BThe remote AC tag ID configured on PE2 must match the remote AC tag ID configured on PE3.

CThe local AC tag ID and the remote AC tag ID configured on PE2 must match.

DThe local AC tag ID configured on PEI must match the local AC tag ID configured on PE3.

Show Answer

Correct Answer: A

The local AC tag ID configured on PE2 must match the local AC tag ID configured on PE1. This ensures that the tag IDs are consistent across both ends of the VPWS service.The remote AC tag ID configured on PE2 does not need to match the remote AC tag ID configured on PE3, as long as they are unique within each PE1.
