Note: Premium Questions for 4A0-115 were last updated On Apr. 18, 2025 (see below)

Question #1

Which of the following statements about the EVPN data plane is FALSE?

Reveal Solution Hide Solution
Correct Answer: D

EVPN-MPLS provides services over an MPLS network, not a simple IP network.The customer data is encapsulated with an MPLS label that identifies the service and then tunneled between the PE routers using MPLS LSPs1.

Verified Reference:Ethernet Virtual Private Networks (EVPNs)


Question #2

Examine the exhibit.

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

Reveal Solution Hide Solution
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.

Verified Reference:Ethernet Virtual Private Networks (EVPNs)


Question #3

The interface-ful numbered model is used for a Layer-3 EVPN service. Which of the following statements is FALSE?

Reveal Solution Hide Solution
Correct Answer: D

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.

Verified Reference:Nokia Ethernet Virtual Private Network Services Course | Nokia


Question #4

Based upon the exhibit,

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

Reveal Solution Hide Solution
Correct Answer: B

PE3 does not add an ESI label to packets forwarded to PE1 because PE1 is connected to the same Ethernet segment.PE3 adds an ESI label only to packets forwarded to PEs that are not connected to the same Ethernet segment, such as PE21.

Verified Reference:Ethernet Virtual Private Networks (EVPNs)


Question #5

Examine the exhibit.

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

Reveal Solution Hide Solution
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.
