Cisco 300-510 Practice Test - Questions Answers, Page 17

An ISP has an MPLS VPN-based network with 12 PE routers. How many peerings are required between the 12 routers if the engineer has not configured route reflectors?

Refer to the exhibit.

Refer to the exhibit. Company A established BGP sessions with several ISPs. A network engineer at the company must filter out all traffic except for routes that transit AS 152. The engineer configured the filtering policy “permit _152S_(_

[0.9])” on R1, but after applying the configuration, the engineer notices that other routes are still visible. Which action resolves the issue?

Refer to the exhibit.

Refer to the exhibit. MPLS traffic from 192.168.4.0/24 to 192.168.5.0/24 is failing to pass over the link from R4 to R2. The engineer verified that:

Cisco Express Forwarding Is enabled on all routers.

All routers reach all networks via OSPF.

MPLS traffic from 192.168.1.0/24 to 192.168.3.0/24 is passing normally over the link from R1 to R2.

Which action resolves the issue?

Refer to the exhibit.

Refer to the exhibit. A service provider has LDP and segment routing running in the network.

Mobility traffic is carried through LDP and enterprise traffic is carried through segment routing.

Which configuration must be implemented to connect the bank branch with the HUB site on routers?

Refer to the exhibit.

Refer to the exhibit. R21 is a multicast source sending multicast traffic 224.1.1.1 to R23, with RP22 serving as the rendezvous point inside AS65222. A network engineer noticed that when R21 goes down, R12 in AS65111 starts to send the same multicast group 224.1.1.1 through RP11. Which action resolves the issue ?

Refer to the exhibit.

Refer to the exhibit. Users at the branch office on R1 reported issue with an application at the home office on R4. While troubleshooting the issue, a network engineer determined that The branch-office users can connect to the home office.

The IS-IS adjacencies between R1 and R2 and R1 and the branch office are up.

Traffic from R1 to the R2 10.20.1.0/24 network is moving normally.

The application at the home office is experiencing packet drops on the connection to the Branch, and R3 cannot reach the R1 172.16.10.0/24 network.

Which action resolves the issues?

Refer to the exhibit.

Refer to the exhibit. After a recent network implementation project, customer A is performing stress testing to verify network redundancy at the branch office connected to R4. When the link from R2 is shut öown as shown, the SLA tracking object fails and the cost of the link between R2 and R4 increases to 100. However, a traceroute operation from a PC in the Branch office shows that traffic to HQ is still routed via R2. Which solution corrects the problem and optimizes traffic flow via R3 without creating operational overhead?

Refer to the exhibit.

Refer to the exhibit. An engineer is troubleshooting an issue with traffic steering using the color-only automated steering mechanism. BGP is failing to automatically steer traffic into an SR policy with the given color of a route, regardless of the next hop. The layer 2 configuration is correct, and the physical connection between the devices is working normally. Whch additional command sequence must the engineer add to correct the issue?

Refer to the exhibit.

Refer to the exhibit. This network is deployed with all connected links configured to run IS-IS. The routing protocol is enacted globally on each router, and the network engineer expects full routing Information to be shared among all routers.

R5 is receiving routes from R4 but is missing routes from R1. Which action corrects the issue so that all routes are shared among the routers?
