x 2.2.2.0/24, with external metric 20. Router R22 redistributes an E2 route for the same prefix/length, external metric 10.Under what conditions will R1 choose as it s best route the route through R22？（）

A. R1 will always choose the route through R22.

B. As long as R1‘s best internal OSPF cost to reach R22 is less than 10.

C. As long as R1‘s best internal OSPF cost to reach R22 is less than 20.

D. R1 will never choo se the route through R22 if the E1 route through R2 is available.

ers, and area 2 with five internal routers. Additionally, one ABR (ABR1) connects areas 0 and 1, plus a different ABR (ABR2) connects areas 0 and 2.How many Type 1 LSAs would b e listed in ABR2‘s LSDB？（）

A. 6

B. 7

1 and I2 used at th e ISPs. R1 peers with I1 and R2; R2 peers with I2 and R1. R1 and R2 do not share a common subnet, relying on other routers internal to the Enterprise for IP connectivity between the two routers.Which of the following could be used to prevent potential routing loops in this design？（）

A. Using an iBGP mesh inside the Enterprise core

B. Configuring default routes in the Enterprise pointing to both R1 and R2

C. Redistributing BGP routes into the Enterprise IGP

D. Tunneling the packets for the i BGP connection between R1 and R2

A. Router R1 will only establish full adjacency with the DR and BDR on broadcast multi- access networks.

B. Router R2 has been elected as a DR for the broadcast multiaccess network in OSPF area 1.

C. Routers R1 and R2 are configured as stub routers for OSPF area 1 and OSPF area 2.

D. Router R1 and R2 are configured for a virtual link between OSPF area 1 and OSPF area 2.

E. The Hello parameters on routers R1 and R2 do not m atch.

lan is to verify the status of type 3 LSAs within the network. Which routers should you verify first to ensure that the configuration s are correct for generating type 3 LSAs？（）

B. Internal routers within the NSSAs

C. Internal routers within the stubby areas

D. ASBRs

E. ABRs

F. DRs and BDRs

A. The LSA was created by an ABR due to an area range command.

B. The LSA was created by an ASBR due to a summary - address command.

C. If cr eated by an area range command, the best metric for a subordinate subnet on that ABR must have been 11.
