NO.76 Refer to the exhibit. A customer reports that Host-1 is failing to receive streaming traffic from the IPTV source. The engineer has confirmed that hosts on router R2 are receiving traffic normally and that Host-1 is correctly sending subscription messages to join the IPTV stream.
Which action must the engineer take to correct the problem?

NO.77 Refer to the exhibit.

CE1 and CE2 cannot communicate through the service provider BGP peering is established between PE1 and PE2. IS-IS is the only routing protocol running in the service provider core.
What
step can be done to troubleshoot the issue?

NO.78 Refer to the exhibit. The service provider environment has these configurations:
– The OSPF backbone area is configured to advertise loopback prefixes.
– The PE routers run the BGP-IPv4 address family in a BGP-free core
topology.
– The broadband users IP subnet 192.168.10.0/24 is redistributed in BGP on PEA.
The operations team noticed route disruptions when broadband subscriber 192.168.10.8 goes offline. Which configuration must an engineer apply to PEA to resolve this problem?

NO.79 Refer to the exhibit.

Which effect of this configuration is true?

NO.80 Refer to the exhibit. P1 and PE3 Cisco IOS XR routers are directly connected and have this configuration applied.
The BGP session is not coming up.
Assume that there is no IP reachability problem and both routers can open tcp port 179 to each other.
Which action fixes the issue?

NO.81 A network engineer is troubleshooting OSPF multiare A.
Which Cisco IOS XR feature should the engineer use in order to streamline OSPF issue?

NO.82 Drag and drop the attributes for the BGP route selection on the left into the correct order on the right. Not all options are used.

NO.83 An engineer configured OSPF on all routers in the data center in the same exchange as other routers. Layer 2 connectivity was established. Now, the engineer plans to implement BFD to detect failures in the forwarding path. Which action must the engineer take?

NO.84 Refer to the exhibit.

The four routers in this network have formed adjacencies. Router R2 is an IS-IS level 1-2 router that connects to other areas, and the attach bit is set in the R2 level 1 LSP advertisements to R1. According to the network design, R2 should push level 2 routes from its routing table to the R1 routing table. However, R1 installed a default route in its routing table. Which action resolves this problem?

NO.85 Refer to the exhibit.

Why is neighbor 10.1.5.5 stuck in “2WAY” state?

NO.86 Refer to the exhibit.

An administrator is troubleshooting Internet access issues on a customer’s network. After applying this ISIS configuration to R1, the administrator notices that it fails to redistribute the default route into IS-IS. After checking the connectivity between the ISIS router and the ISP router the engineer confirmed there is Layer 3 connectivity between them Which action should be taken to correct the problem?

NO.87 A network engineer must configure a Cisco IOS XR router with BGP dampening.
Which configuration meets these parameters?

NO.88 In a PIM-SM environment, which mechanism determines the traffic that a receiver receives?

NO.89 Refer to the exhibit.

An engineer has successfully fixed BGP peering issue. R1 has an established eBGP peering with R2 and R3. Which mechanism should the engineer apply in order to steer the traffic correctly?

NO.90 Refer to the exhibit.

NO.91 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?

NO.92 Refer to the exhibit.

An engineer is troubleshooting connectivity issues on the MPLS core network. A customer connected through R4 cannot reach the OSPF domain on R5. While checking the routing table of R1, the engineer cannot see all the routes from R3 and R5. Which task must the engineer perform so that R4 is able to reach R5?

NO.93 Refer to the exhibit. Router1 and Router2 have shared routes in the OSPF database, but the routes are missing from their routing tables. Checking the prefix-list configuration on both routers, the engineer confirmed all networks are allowed. What action should the engineer take to fix the problem?

NO.94 Refer to the exhibit. Router 1, Router 2, and Router 3 are co-located in an onsite data center of an office, but Router 4, Router 5, and Router 6 are installed in another data center several miles away. A network engineer is troubleshooting an RSVP- issue on the network. On most of the devices, the engineer can move all LSPs away from a selected interface and take it down for maintenance without interrupting traffic. However, when an interface on Router 3 is taken down, traffic on the network is disrupted. What must the engineer enable to resolve the issue on Router
3?

NO.95 Refer to the exhibit.

Routers RA and RB are IS-IS peers configured for NSF but router RC is an IS-IS peer without NSF capability If RA undergoes processor switchover what is the effect on the network environment?

NO.96 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 oown 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?

NO.97 Refer to the exhibit.

Routers within the cluster are not receiving the desired prefixes. What must be done to fix the issue?

NO.98

Refer to the exhibit. Routers R1. R2, R3. and R4 are peer routers that reside in different administrative domains. PIM-SM is running in each autonomous system, and EBGP is configured between the peers. A network administrator has just implemented MSDP between the connected peers. When the administrator enabled the MSDP configuration. R1 and R2 failed to establish a peering relationship. All other connected routers successfully established peering sessions Which action must the engineer take to resolve the issue between R1 and R2?

NO.99 Refer to the exhibit

Which router does R1 install as an alternate next hop when trying to reach R3 if LFA is enabled?

NO.100 Which two conditions must be met before separate ISPs can provide interdomain multicast routing? (Choose two.)
