Demo Questions
Question 1
Based upon the exhibit, which of the following statements is FALSE?
- PEI populates this information into the local VPLS FDB.
- Neighbors 10.10.10.2 and 10.10.10.3 have proxy-ARP enabled for the VPLS.
- Neighbors 10.10.10.2 and 10.10.10.3 have a service that uses a network identifier of 10.
- PEI uses VXLAN tunnels to reach neighbors 10.10.10.2 and 10.10.10.3.
Correct answer: D
Explanation:
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. 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 2
Proxy-ARP/ND is operational for a VPLS. Which of the following statements is FALSE?
- The PE has proxy-ARP and dynamic-populate enabled for the VPLS.
- The proxy-ARP table is populated by snooping IP packets received from remote PEs.
- When the PE learns a local host IP address, it adds an entry into its proxy-ARP table.
- The PE advertises a MAC/IP route that includes the MAC and IP address of a local host.
Correct answer: C
Explanation:
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. 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 3
Based upon the exhibit, which of the following statements is FALSE?
- VPLS 10 must be configured with two BGP instances on PE3 and PE4.
- On PE3 and PE4, VPLS 10 must be configured with two different route-distinguisher values: one for VXLAN and another for MPLS.
- On PE3 and PE4, VPLS 10 must be configured with two different route-target values: one for VXLAN and another for MPLS.
- A BGP export policy is required on PE3 and PE4 to ensure that IMET routes originated with VXLAN encapsulation are not advertised to the peer across the core network.
Correct answer: A
Explanation:
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. 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.
