Routing protocols are rules used by routers to discover routes, create routes, and maintain

routing tables for packet forwarding. Routes can be classified into which of the following types

based on their source?

• Dynamic routing

• Static Route

• Direct Route

• External Route

In an OSPF process of a router, the import - route command can be used to import the routes

of other OSPF processes.

• TRUE

• FALSE

The following figure shows the OSPF network of an enterprise and the OSPF configurations of

R1.Which of the following statements is false about the network?

• R2 can access the server.

• GE 0/0/1 of R1 cannot accept OSPF packets.

• GE 0/0/1 of R1 cannot send OSPF packets.

• The network segment to which GE 0/0/1 of R1 belongs cannot be advertised.

An enterprise uses OSPF to implement network communication.To ensure data validity and

security, all authentication modes supported by OSPF are enabled on routers.In this case,

interface authentication is preferentially used by the routers.

• TRUE

• FALSE

Which of the following is the default dead time of an interface on an OSPF P2P or broadcast

network?

• 10s

• 40s

• 120s

• 60s

OSPF networks are classified into four types of networks by link layer protocol.Which of the

following types of networks do not require DR/BDR election?

• NBMA

• P2MP

• Broadcast

• P2P

On an OSPF network, two routers exchange DD packets after establishing a neighbor

relationship. The DD packets contain multiple fields.Drag the following fields to their meanings.​

• DD Seq → Ensures the reliability and integrity of DD packets during transmission.

• MS-bit = 1 → Indicates that the sender is the master.

• I-bit = 1 → Indicates the first DD packet.

• M-bit = 1 → Indicates that there are subsequent DD packets.

On an OSPF network, there are multiple types of packets, each with a different function.Which

of the following are the main functions of Hello packets?

• Neighbor relationship maintenance

• Neighbor discovery

• Neighbor deletion

• Neighbor relationship establishment

OSPF has several types of special areas, which are used to reduce the LSDB size and

improve device performance. Which of the following LSAs cannot be in a totally stub area?

• Type 3 LSA that describes a default route

• Type 1 LSA

• Type 3 specific LSA

• Type 2 LSA
