Refer to the exhibit A network engineer installed a new router (router 3) at the regional hub running MPLS services for scalability Router 3 is connected to the 10.44 4.0,'24. 10.44 5.024. 10 44.6.0/24. and 10 44 7 0/24 subnets The new router has been configured for OSPF area 2. and it is advertising the four connected networks. The engineer noticed that the same networks are listed as interarea summary routes, and they are being flooded into each area on the area borders Which action resolves the issue?

• A.Under the OSPF configuration on router 3. add area 2 range 10.44.4.0 255.255.252.0.
• B.On router 3, configure an access list to filter the networks.
• C.Under the OSPF configuration on router 2, add area 2 range 10.44.4.0 255.255.252.0.
• D.On router 2, configure a route map to filter the networks.

Which difference must an engineer consider when choosing whether to implement OSPF or IS-IS as the routing protocol on the network?

• A.To support fast convergence. OSPF uses the LSA arrival timer and IS-IS uses the PRC-interval timer.
• B.IS-IS supports ordinary, stub, totally-stub. and NSSA areas, but OSPF supports only stub areas.
• C.IS-IS links are associated with either a Level 1 area or a Level 2 area at one time, but OSPF links are associated with multiple areas at one time.
• D.The OSPF DR election process is deterministic, and the IS-IS DS election process is not deterministic.

Which difference should be considered when intradomain or interdomain multicast routing is implemented?

• A.Interdomain multicast routing relies on PIM-DM and intradomain multicast routing relies on PIM- SM.
• B.Interdomain multicast routing requires an IS-IS or OSPF neighbor relationship between the domains but intradomain multicast routing requires only BGP Questions & Answers PDF P-57
• C.A network uses intradomain multicast routing without interdomain routing but networks that use interdomain multicast routing must also apply intradomain routing
• D.interdomain multicast routing uses BIDR-PIM to establish neighbor relationships between AS and interdomain multicast routing uses MSDP

Refer to the exhibit. Routers CE1 and CE2 are in AS 65530. which is multihomed for Internet access. An engineer expects inbound traffic to AS 65530 to arrive from PE1. but it is coming from PE2 instead PE1 and PE2 routers are connected with CE routers through the same bandwidth Which action must be taken to correct the problem?

• A.Set the local-preference value on router CEI to 100 or greater
• B.On router PEI , change the origin for routes that are redistributed from CEI to CE2.
• C.On router CE2, configure inbound routes from PE2 to CE2 with a local-preference value of 50 or greater.
• D.Configure router CEI to prepend the AS path to routes it receives from PE 1.
