Based upon the exhibit,



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

  1. PE3 replicates the traffic and sends it to all PES in its VPLS I flooding list.
  2. PE3 adds an ESI label to packets forwarded to PEI because PEI is connected to the same Ethernet segment.
  3. PEI forwards the traffic received from PE3 to CEI, and CEI discards it based upon the ESI label.
  4. PE2 decapsulates the packets received from PE3 and forwards the frames to CE2.

Answer(s): B

Explanation:

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.

In the exhibit,



MACI moves from PEI to PE2.
Which of the following actions related to this MAC address mobility is performed?

  1. CEI generates an update message to PEI withdrawing its MAC.
  2. PEI generates an update message to remote PES identifying the new location of CEI.
  3. PE2 advertises a MAC/IP route for MACI with a sequence number higher than that received from PEI.
  4. PE3 waits to receive a data packet from CEI to update its FDB entry for MACI.

Answer(s): C

Explanation:

PE2 advertises a MAC/IP route for MAC1 with a sequence number higher than that received from PE1. This indicates that MAC1 has moved from PE1 to PE2 and triggers a MAC withdrawal message from PE1 to remote PEs. CE1 does not generate an update message to PE1 withdrawing its MAC, nor does PE1 generate an update message to remote PEs identifying the new location of CE11. Verified

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

  1. To advertise the MAC or MAC/IP addresses of locally-learned hosts
  2. To advertise the redundancy mode of a local Ethernet segment
  3. To discover all PES participating in the same VPIS service
  4. To discover all PES attached to the same Ethernet segment

Answer(s): C

Explanation:

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.



Based on the exhibit below, which of the following statements is FALSE?



When forwarding BUM traffic, the local PE must replicate the traffic and send it as unicast to the advertising neighbor.

  1. The MPLS label 524284 presented indicates the service label value that the neighbor 10.10.10.2 uses to forward BUM traffic to PEI.
  2. When forwarding BUM traffic, the local PE uses an MPLS transport tunnel towards the advertising neighbor.
  3. The IMET route is imported by a local VPLS configured with a route-target value of 65100:10.

Answer(s): A

Explanation:

When forwarding BUM traffic, the local PE does not replicate the traffic and send it as unicast to the advertising neighbor. Instead, the local PE uses an MPLS transport tunnel towards the advertising neighbor and sends the traffic with an MPLS label that indicates the service.



Based on the exhibit below, which of the following statements is TRUE?

  1. PE2 advertises this BGP update for a locally-configured VPWS service.
  2. PEI uses this BGP update to build the flooding list of the associated service.
  3. PEI uses MPLS label 524284 when sending traffic destined to
  4. Neighbor 10.10.10.2 is connected to a multi-homed CE.

Answer(s): B

Explanation:

PE1 uses this BGP update to build the flooding list of the associated service. The update contains an IMET route that indicates that neighbor 10.10.10.2 is participating in a VPLS service with a network identifier of 10.

question 31 has obviously wrong answers. tls and ssl are used to encrypt data at transit, not at rest.

i have a lot of experience but what comes in the exam is totally different from the practical day to day tasks. so i thought i would rather rely on these brain dumps rather failing the exam.
