Referring to the exhibit, you want to make ISP1 your preferred connection for inbound and outbound traffic. Which two steps will accomplish this task? (Choose two.)

You must configure an OSPF virtual link to facilitate communication between Area 0 and Area 20. Referring to the exhibit, which two addresses should you use as the neighbor IDs of the virtual link endpoints? (Choose two.)

A network administrator is investigating why traffic from R2 is not being forwarded to R1. Referring to the show isis database command output shown in the exhibit, what is causing this problem on the network?

Which two statements are true about what a route reflector does by default when distributing routes it has received from reflector clients? (Choose two.)

Referring to the exhibit, which two statements are true? (Choose two.)

A Layer 3 VPN exists in the provider network and the CE devices are connecting to the PE devices using BGP. The PE devices are receiving BGP routes from the CE devices and the PE devices have the CE BGP routes in their respective routing tables. However, the remote CE devices are not receiving the BGP routes. Referring to the exhibit, what is the problem?

R1 assigns incoming voice traffic to the ef forwarding class. All other traffic is assigned to the best-effort forwarding class. You have configured a CoS re-write rule on R1 to include the correct CoS bit values in packets sent towards R2. You want R2 to classify traffic using the CoS markings created by R1. Which two configuration steps are necessary to accomplish this task? (Choose two.)

You have a mixed vendor EVPN environment and you need to ensure VXLAN interoperability between all devices. In tins scenario, winch statement is correct?

Referring to the exhibit, which command would reduce the size of the OSPF database and corresponding routes?

R2 has IS-IS adjacencies with R3 and R4. You want to ensure that R2 has both a level 1 and level 2 adjacency to both R3 and R4, but R2 only has one adjacency with R4. Referring to the exhibit, which configuration change will solve this issue?

Your router should be configured with a rewrite rule which alters the default behavior of expedited forwarding as shown in the exhibit. In this scenario, which configuration is correct?

You have the LDP signaled VPLS topology as shown in the exhibit. CE-B at Site-2 is multihomed to both PE-2 and PE-3. In this scenario, where would you configure loop prevention?

What information is stored in a VRF table for a BGP Layer 2 VPN? (Choose three.)

You are asked to configure a series of interface policers and firewall filters, which include policers, on the same device. You must ensure that the two configuration methods do not conflict. What are two considerations when performing this task? (Choose two.)

Why do interprovider option B VPNs scale better than interprovider option A VPNs?

Referring to the exhibit, which two statements are true? (Choose two.)

You are responsible for configuring CoS for your network Your network includes a video application with strict latency requirements, so that any packets delayed by more than 75 ms are effectively useless. You want to ensure that you do not waste buffer space. When configuring the scheduler for this application, which feature would you use?

Which two statements about wide and narrow metrics used in IS-IS are correct? (Choose two.)

R2 is receiving the same route from R1 and R3. You must ensure that you can load balance traffic for that route. Referring to the exhibit, which two configuration changes will allow load balancing? (Choose two.)

A customer recently migrated to IS-IS and is concerned about resource starvation when the routing protocol daemon (RPD) starts. To resolve this issue and protect R2 and R3, which feature should you implement?
