What are two differences between OSPF and IS-IS? (Choose two.)
OSPF is a link-state routing protocol, and IS-IS is a distance-vector routing protocol.
OSPF uses a router ID to identify a router, and IS-IS uses a system ID.
OSPF elects a DR and a BDR, and IS-IS elects a DIS.
Unlike OSPF. IS-IS supports virtual links.
Unlike IS-IS routers, an OSPF router belongs to only one area in addition to the backbone area.
A network engineer is troubleshooting OSPF multiare a. Which Cisco IOS XR feature should the engineer use in order to streamline OSPF issue?
hierarchical CLI
routing process enabled by default on all interfaces
DR support for topology management
show lp ospf topology command
Refer to the exhibit.
Routers within the cluster are not receiving the desired prefixes. What must be done to fix the issue?
Clients in that cluster must have full mesh connectivity between eBGP peers.
No client-to-client must be disabled.
Clients in that cluster must have full mesh connectivity between iBGP peers.
No client-to-client reflection must be enabled.
Refer to the exhibit.
A network operator is working to deploy a Unified BGP design and allow it to be available only in selected markets and services in the future. The label allocation is not functioning as desired. Which action will fix the issue?
Remove the allocate-labels command.
Reconfigure the route-policy ALL_LABELS to match all after the drop.
Reconfigure the route-policy ALL_LABELS to pass.
Remove the route policy and only configure "allocate-label".
An engineer is working to implement segment routing protocol on the customer's core network.
Which step should the engineer take before the segment routing is enabled and is running with BGP?
Segment routing must be configured with ISIS.
Segment routing must be configured with EIGRP.
Explicit-null must be configured for all neighbors.
MPLS must be configured.
After changing the IP address on an IOS XR router, an engineer cannot ping the new address Which step did the engineer forget to complete?
commit the configuration
roll back the configuration
save the running configuration
merge the configuration
Refer to the exhibit.
The green policy is designed with low delay, and the pink policy is designed with low cost. What is the next hop for node A on its way to node D, with the objective of achieving a low delay?
192.168.3.2
192.168.1.6
192.168.3.6
192. 168.1.2
Refer to the exhibit.
A network operators configuring BGP PIC on CE1 on already established neighborships with PE1ana PE2 inside the fully converged MPLS network Which element needs to be implemented to make this feature function effectively?
Bidirectional Forwarding Detection must be applied to the upstream facing BGP interfaces.
The operator must ensure that all prefixes have the same next-hop from PE1 and PE2 for BGP PICA reserved BGP
community of 1 10 must be used to denote the PIC feature set to the routing protocol
BGP import export policies must be applied on all devices for the routes needing BGP for PIC
Refer to the exhibit.
What is the effect of this configuration?
It sets the keepalive timer to 30 milliseconds and the hold timer to 240 milliseconds.
It sets the keepalive timer to 30 seconds and the hold timer to 240 seconds.
It sets the hold timer to 30 milliseconds and the keepalive timer to 240 milliseconds.
It sets the hold timer to 30 seconds and the keepalive timer to 240 seconds.
Which two differences should be considered when deciding whether to implement to implement routing policies or route maps? (Choose two.)
Sequences are added after implementing a route map, but routing policies must be reconfigured when change is needed.
Route maps are implemented using hierarchical policies, but routing policies must be implemented sequentially.
Route maps require an explicit deny at the end of the sequence, but routing policies have an implicit deny at the end of the program.
Route policies require sequence numbers, but route maps are implemented without sequencing.
Route maps are supported in Cisco 10S Software and routing policies are supported in Cisco IOS XR Software.
