What is the characteristic of enabling segment routing for IGPs?
- A . Segment routing must first be enabled under the routing process and then globally.
- B . Segment routing must first be enabled globally and then under the routing process.
- C . Segment routing must be enabled only globally.
- D . Segment routing must be enabled only under the routing process.
Refer to the exhibit.
An engineer is troubleshooting a networking issue with several symptoms
✑ The shortest path from router R1 to R8 is underused and the longest path is overused
✑ Traffic from 10.1.1 1 to 10 8 8 8 is routed on the longest path
✑ Traffic between the R1 and the application server is experiencing packet drops and latency problems.
Which action resolves the issue?
- A . Configure route leaking for the IP address Of the application server on router RI.
- B . Increase the RI to R2 link metric to 20.
- C . Configure a Level 2 IS-IS domain on router RI.
- D . Block the advertisement of the application server IP address to router R6.
An engineer is troubleshooting slow performance issues on a customer’s network after the last multicast configuration change was applied on it While checking the running configuration on the router the engineer notices there are many ip igmp join-group commands applied on several interfaces of the router which caused the high CPU utilization usage.
What action must the engineer take to solve this issue?
- A . Configure ip igmp static-group command on all interfaces
- B . Remove ip igmp join-group command on all unnecessary interfaces
- C . Configure all router interfaces to be process-switched by increasing the query interval
- D . Remove unnecessary members from the IGMP group
Which task is performed when troubleshooting LDP?
- A . Execute the ping utility to generate information about the MAC addresses used along the path
- B . Verify that MPLS is disabled globally and enabled on the necessary interfaces in a per-interface basis
- C . Execute the traceroute utility to generate information about the labels used along the path
- D . Verify that Cisco Express Forwarding has been disabled on the network
A network engineer is troubleshooting OSPF multiarea.
Which Cisco IOS XR feature should the engineer use in order to streamline OSPF issue?
- A . hierarchical CLI
- B . routing process enabled by default on all interfaces
- C . DR support for topology management
- D . show lp ospf topology command
What are two features of dual-stack? (Choose two.)
- A . It is implemented without excessive processing power.
- B . It supports IPv4 and IPv6 traffic on the same infrastructure.
- C . It allows an engineer to stack multiple Layer 2 switches to serve as a single switching unit.
- D . It requires tunneling IPv6 traffic over an IPv4 infrastructure.
- E . It securely routes and tunnels traffic between separate sites over the Internet.
Refer to the exhibit.
An engineer applied the summarization configuration on R1 for four networks (192.168.20.0/24 to 192.168.23.0/24) in area 1 and eight networks (192.168.32.0/24 to 192.168.39.0/24) in area 2 to stop the flooding of all the customer routes. While checking the routing table of R2, the engineer noticed that R1 is still sending only specific routes to R2.
Which configuration should the engineer apply on R1 to summarize routes?
- A . Option A
- B . Option B
- C . Option C
- D . Option D
Refer to the exhibit.
A network engineer configured three new PE routers to expand the network. The new routers run in the IS-IS routing protocol and reside in the data center in the same exchange as the existing routers. However, the network is now experiencing suboptimal routing. The Layer 2 configuration and VLANs are configured correctly to provide segregation between networks, but the Level 1 routes are not being converted to Level 2 routes.
Which action resolves the issue?
- A . On Router 1, redistribute the routes into IGP.
- B . On Router 1, summarize internal routes between areas.
- C . On Router 2, redistribute the routes into IGP.
- D . On Router 2. summarize internal routes between areas.
Refer to the exhibit.
An engineer is troubleshooting a network routing issue on this IS-IS network situated at the customer’s regional hub. Router 2 that runs Cisco IOS XR Software cannot see the network 10.1.1.0/24 on router 1. The Layer 2 encapsulations are correct. The ARP connectivity for the Ethernet interface that runs IS-IS is working.
Which action resolves the issue?
- A . On router 1, remove the CISCOLIVE keyword after the Ip router Isis command under interface GigabitEthernet0/2.
- B . Under the router isis command on router 1. change is-type level-1 to is-type level-2
- C . On router 1. add the CISCOLIVE keyword after the Ip router isis command under interface GigabitEthernet0/3.
- D . Under the router isis command on router 2. change is-type level-1 to is-type level-2
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?
- A . Configure segment-routing Sr-prefer prefix-list on AG1 and AG2 router for 10.10.10.10/24.
- B . Enable segment-routing Mpls Sr-prefer on CR1 and CR2 routers for 10.0.0.0/8.
- C . Enable segment-routing Mpls Sr-prefer on AG1 and AG2 routers for 10.0.0.0/8.
- D . Configure segment-routing sr-prefer prefix-list on CR1 and CR2 routers for 10.20.20.10/24.
