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

The OSPF DR election process is deterministic, and the IS-IS DS election process is not deterministic.

The OSPF DR election process is deterministic, and the IS-IS DS election process is not deterministic.

To support fast convergence. OSPF uses the LSA arrival timer and IS-IS uses the PRC-interval timer.

To support fast convergence. OSPF uses the LSA arrival timer and IS-IS uses the PRC-interval timer.

IS-IS supports ordinary, stub, totally-stub. and NSSA areas, but OSPF supports only stub areas.

IS-IS supports ordinary, stub, totally-stub. and NSSA areas, but OSPF supports only stub areas.

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.

Do not change the enable password or hostname for any device. Save your configurations to NVRAM before moving to the next item. Click Next at the bottom of the screen to submit this lab and move to the next question. When Next is clicked, the lab doses and cannot be reopened. Topology Tasks Configure and verify an OSPF neighbor adjacency between R1 and R2 in OSPF area 0 according to the topology to achieve these goals: 1. R1 pings the Loopback0 interface of R2. Use interface-level configuration to complete this task. 2. R2 pings the Loopback0 interface of R1. Use interface-level configuration to complete this task. 3. R2 receives a single summary route 172.16.100.0/22 for networks 172.16.100.0/24, 172.16.101.0/24, and 172.16.103.0/24.
