A network operator is getting the route for 10.11.11 0/24 from two upstream providers on #XR3. The network operator must configure #XR3 to force the 10.11.11.0/24 prefix to route via next hop of 10.0.0.9 as primary when available. Which of these can the operator use the routing policy language for, to enforce this traffic forwarding path?

A. weight of 0 on the prefix coming from 192.168.0.2

B. lower local preference on the prefix coming from 192.168.0.2

C. higher local preference on the prefix coming from 192.168.0.1

D. weight of 100 on the prefix coming from 192.168.0.1

Refer to the exhibit.

A service provider technician is working on a multicast issue for a customer. While checking the multicast table, the technician notices that no flags are present for the (1.1.1.1, 239.1.1.1) entry, yet flags are present for the (1.1.1.1, 232.1.1.1) entry.

Which factor might explain this issue?

A. Only the administratively scoped range is permitted

B. Only ASM is permitted

C. Only the default SSM range is permitted

D. Only GLOP is permitted

An engineer is troubleshooting an OSPF issue. Router 1 has a neighbor relationship with router 2. Only router 1 classful EIGRP routes can be seen on router 2. In order for all EIGRP routes to be redistributed correctly, which action should be taken?

A. Router 1 must have the keyword subnets included in the redistribution command for all EIGRP routes to be redistributed.

B. Router 1 must remove the AS number 1 from the redistribution command for all EIGRP routes to be redistributed.

C. Router 1 must have the keyword ospf-metric included in the redistribution command for all EIGRP routes to be redistributed.

D. Router 1 must have the keyword metric-type 1 included in the redistribution command for all EIGRP routes to be redistributed.

CE1 is the gateway router into the provider network via PE1. A network operator must inject a default route into OSPF area 0. All devices inside area 0 must be able to reach PE1. Which configuration achieves this goal?

A. Option A

B. Option B

C. Option C

D. Option D

Refer to the exhibit.

A network engineer applied configuration on R5 to summarize all OSPF routes, but R4 is still receiving specific routes from R5. The engineer has confirmed that both R5 and R4 routers are configured with correct summarization configuration, but R5 is not sending the summary routes. What action must the engineer take to fix the problem?

A. Remove summarization configuration on R5 and configure it on R4

B. Clear link-state database on both R4 and R5 routers for summarization to work

C. Configure a sham link between R4 and R5 to support summarization within Area 2

D. Move R4 and R5 in separate areas as now they maintain the same link-state database

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:

1.

The branch-office users can connect to the home office.

2.

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

3.

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

4.

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?

A. Redistribute static connected routes in IS-IS on router RI.

B. Configure the IS-IS core instance on the RI GigabitEthernet0/3 interface.

C. Redistribute static connected routes in IS-IS on router R4.

D. Configure the IS-IS core instance on the R2 GigabitEthernet0/1 interface.

C. security

D. automatability

A network operator working for a telecommunication company with an employee id: 4074:92:707 is planning to implement the Nonstop Forwarding (NSR) feature on the customer's core network. After getting the configuration ready for NSR. on which router should the operator implement NSR changes?

A. on the CE router

B. on the ASBR router

C. on the ABR router

D. on the PE router

While configuring Cisco NSF awareness, a network engineer enters the bgp graceful-restart command after the BGP session is established in a router that runs IOS XE Software. Graceful restart capabilities are not exchanged. Which two actions should be taken? (Choose two.)

A. Reload the router

B. Verify that BGP route dampening is configured

C. Reduce BGP convergence time

D. Issue the clear ip bgp * command

E. Issue the show ip bgp neighbors command.
