Question # 31

For which reason do you deploy BGP confederations within a BGP transit backbone?

to support a larger number of eBGP peer sessions

to increase the number of routes that can be redistributed between the running IGP and BGP

to reduce the number of eBGP routes that must be shared between autonomous systems

to reduce the number of iBGP peering sessions

Question # 32

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?

Configure BFD on any one of the routers

Configure IS-IS routing before implementing BFD.

Configure BFD between each adjacent router

Configure CEF before implementing BFD

Question # 33

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 ' eral miles away. A network engineer is troubleshooting an RSVP-TE issue on the network. On most of the devices, the engineer can move all LSPs away from a selected dace 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?

FRR

NSR

soft-preemption feature

Soft-disperse

Question # 34

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.

Question # 35

Drag and drop the features from the left onto the corresponding routing protocols on the right

Question # 36

What are the two characteristics of route reflectors? (Choose two.)

If a router received an iBGP route with the originator-ID attribute set to its owm router ID, the route is discarded.

Routes received from nonclient peers are reflected to route reflector clients as well as nonclient peers.

Routes received from nonclient peers are reflected to route renector cluster as well as OSPF peers.

If a route reflector receives a route with a cluster-list attribute containing a different cluster ID, the route is discarded.

Routes received from a route reflector Client are reflected to other clients and nonclient peers.

Question # 37

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?

Question # 38

Refer to the exhibit.

VPN users that are connected to PE routers are facing network issues. Traffic that originates from CE1 drops before reaching CE2. An engineer finds no outgoing traffic statistics on PE1 and PE2 routers toward CE devices and finds that the PE1 router is running the older software image. Which action must be implemented to resolve the issues?

Enable LDP protocol on PE1 and PE2 routers.

Advertise P1 router loopback on PE1 in OSPF.

Enable CEF-based forwarding on PE1 router.

Advertise PE2 router loopback on PE1 in OSPF.

Question # 39

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 connecti on between the devices is working normally. Whch additional command sequence must the engineer add to correct the issue?
