What are two differences between OSPF and IS-IS? (Choose two.)

• A.Unlike IS-IS routers, an OSPF router belongs to only one area in addition to the backbone area.
• B.OSPF uses a router ID to identify a router, and IS-IS uses a system ID.
• C.OSPF elects a DR and a BDR, and IS-IS elects a DIS.
• D.OSPF is a link-state routing protocol, and IS-IS is a distance-vector routing protocol.
• E.Unlike OSPF. IS-IS supports virtual links.

Routers R1, R2. R3, and R4 have been configured to run OSPF. and router R5 is running EIGRP Traffic from R1 to R5 is expected to pass via R4. but OSPF routing has calculated the best path via R3. Which action corrects the problem?

• A.Configure R3 to use metric-type 1 with a higher metric than R4.
• B.Change the metric-type value on R3 to 2.
• C.Reconfigure R1 in Area 0.
• D.Configure R1 with a static route to the R5 networks and set R5 as the next hop.

R1 is directly connected to R2 and R3. R1 is in BGP AS 123, R2 is in BGP AS 2, and R3 is in BGP AS 3. Assume that there is no connectivity issue between R1, R2 and R1, R3. Which result between BGP peers R1, R2 and R1, R3 is true?

• A.The BGP session comes up between R1 and R2, but not between R1 and R3.
• B.The BGP session comes up between R1 and R3, but not between R1 and R2.
• C.The BGP session comes up between R1 and R2 and between R1 and R3.
• D.The BGP session does not come up between R1 and R2 and between R1 and R3.
