On a network, each router has a local core routing table and protocol routing tables. A routing entry in the local core routing table has multiple key fields. Which of the following are included?

On an office network of an enterprise, OSPF is enabled on two directly connected routers. During adjacency establishment, the state machine stays in the 2-way state. Which of the following statements are not possible causes?

A campus network uses OSPF for network communication. The display ospf peer command is run on a router, and the command output is as follows:

Which of the following statements are true about the device?

OSPF has multiple types of routes with varying priorities. Which of the following types of routes has the lowest priority when they have the same prefix?

An enterprise administrator configures route summarization on ASBRs to reduce the number of inter-area Type 3 LSAs, which in turn reduces the routing table size and improves device resource utilization.

OSPF networks are classified into broadcast, P2P, P2MP, and NBMA networks. Which of the following types of networks use the default Hello time (30s)?

On an IS-IS network, two directly connected routers establish a neighbor relationship through the three-way handshake mechanism by default, regardless of whether the network type is P2P or broadcast.

On an IS-IS network, areas are divided by router, and a router can belong to only one are a. Therefore, an IS-IS router only needs to maintain the LSDB of its area.

An enterprise administrator views the following details about a BGP route during routine O&M:
