Refer to the exhibit. PE1 is located at a company's headquarters, with PE2 and PE3 at remote offices. A service provider implemented E-Tree for the company, with PE1 serving at the root and PE2 and PE3 serving as leaf nodes in the topology. For redundancy, PE3 offers some of the same services that that offered at headquarters. However, when the link to PE1 fails, users on PE2 cannot access the services on PE3. Which action must the engineer take to resolve the issue?

• A.Change the L2transport encapsulation type to MPLS.
• B.Reconfigure PE3 as a root node.
• C.Set the same MAC address for MLACP on each device.
• D.Add a secondary IP address to the interface facing the EVPN.

Refer to the exhibit. A customer with multiple sites requested additional monitoring for Ethernet connections to its service provider. The service provider implemented Ethernet OAM on the PE side of the PE-CE links between the PE and CE routers. Which command must be implemented on both CEs to support Ethernet OAM and allow the PE to initiate the connection?

• A.ethernet uni id 2004-20
• B.ethernet oam mode passive
• C.ethernet cfm mip level 7
• D.ethernet oam max-rate 8

Which requirement must be implemented when an organization implements BGP as its PE-CE routing protocol and the CE sites exist in the same autonomous system?

• A.The next-hop-self command must be configured on the PE for each VPNv4 neighbor within the same autonomous system.
• B.The PE must send labels to the CE.
• C.The AS-Override feature must be configured.
• D.The PEs must be placed in a different autonomous system from the CEs.

Which BGP feature causes to replace the AS number of originating router with the AS number of the sending router?

• A.route dampening
• B.AS override
• C.route reflectors
• D.confederations

Refer to the exhibit. As their network ages and traffic increases, the network-engineering team at a small company is concerned that links may degrade in performance over time, which makes the degradation difficult to detect before becoming widespread. The team decided to implement Ethernet OAM to monitor links to certain critical resources, such as the file server.
Which action must the team take so that remote OAM is alerted when a fault occurs?

• A.Enable remote loopback mode to provide real-time notifications.
• B.Implement CFM on R1 with a maintenance level of 6.
• C.Deploy remote failure indication on ports of concern.
• D.Implement NTP and enable caching.
