Q10. An ISP provides a major client MPLS VPN for managed services. The MPLS engineering team needs to use the advanced VPN feature of selective VRF import so that only specific prefixes are present in the required VPNs.
Which aspect of this feature must the team consider?

How should the engineer update the configuration on R1 to correct the problem?

Q14. Refer to the exhibit.

Which statement describes the result of this BGP configuration?

Q15.

What is the effect of this configuration?

Q16. An engineer noticed that PE3 is failing to accept IPv6 traffic information from PE1.
The engineer confirmed that both PE3 and PE1 routers are configured accurately with IPv6 protocol.
To eliminate IPv6 traffic loss issue, which action must the engineer take to solve the problem?

Q17. Refer to the exhibit.

While provisioning a new BGP session between the PE and CE router, you issue the as- override command.
Which statement describes modification of the prefix before being sent to the CE router (10.10.10.1)?

Q18. Refer to the exhibit.

Which result occurs when PE1 learns a new MAC address and all three PEs are enabled with EVPN native?

Q19. While troubleshooting an AToM L2VPN service, a network consultant notices that the AC Layer 2 encapsulations are different. Which action should the consultant take in order to make the MPLS L2VPN work?

Q20. Refer to the exhibit.

Drag and drop the EVC configuration items from the left onto the correct descriptions on the right.

Q21. In a typical service provider environment, which two tools are used to help scale PE router connectivity requirements? (Choose two.)

Q23. Refer to the exhibit.

A network operator is implementing EVPN IRB on PE1. Which two command placements enable the advertisement of Type 2 routes and what information do Type 2 routes contain? (Choose two.)

Q24. An engineer is troubleshooting an EoMPLS circuit on a Cisco IOS XR router interface that removes a VLAN from the distribution layer. Which configuration should the engineer apply in order to accomplish the task?

Q25. When verifying Layer 3 MPLS VPN operations, which Cisco IOS XR show command is best used to verify that the PE router is receiving the routes from the CE router?

Q26. A network engineer is implementing Layer 3 MPLS VPNs on Cisco IOS/IOS XE PE routers.
Which PE-to- CE routing protocol requires a separate routing process to be created for each VRF?

Q27. The CTO of a company requires the support of a network consultant to deliver an MPLS solution without resigning to a certain degree of redundancy and scalability. Which solution effectively scales to hundreds or thousands of sites?

Q28. While implementing Layer 3 MPLS VPN, which feature should an engineer use at the PEs to transform the customer IPv4 prefixes into a unique 96-bit prefix?

Q29. How do Ethernet virtual circuits provide a way for service providers to maximize the use of VLAN tags’-1

Q30. Which mechanism reduces the network flooding caused by host ARP learning behavior?
