In the OSPF routing protocol, is there a way to solve the problem that the non-backbone area and the backbone area cannot be directly connected?

A. Setting up ABR B. Set the STUB area C. Setting up ASBR D. Setting up a virtual connection

Correct Answer: D

QUESTION NO: 3
What is the correct statement about the use of split horizon technology for distance vector routing protocols?
(multiple choice)

A. Work in conjunction with the route suppression (holddown) mechanism to avoid routing loops to a certain extent. B. Ensure that routing information is no longer sent to the interface that receives the routing information during routing information transmission. C. Instead of the poison reverse algorithm D. Avoid routing loops between adjacent routers

Correct Answer: A,B,D

QUESTION NO: 4
According to the principle of STP protocol, all ports of the root switch are ()

A. Backup port B. Root port C. Blocking the port D. Designated port

Correct Answer: D

QUESTION NO: 5
Regarding VRRP, is the following statement correct?

A. In the backup fault-tolerant protocol, there is also an HSRP protocol. This protocol is identical except that the packet structure is different from VRRP. B. If there are multiple backups, the election priority will be the new master according to the VRRP packets sent. C. The master sends VRRP packets periodically. If the backup does not receive packets for a long time, the status is changed to Master. D. Backup sends VRRP packets periodically. If the master receives the packets from the backup, the master compares the priorities and determines whether the status is set to Master or Backup.

Correct Answer: C

It is the process for a router to reach the stable and consistence state after the network changes. C. Convergence is a process that occurs due to network topology changes. D. Convergence is a process of establishing neighbor relationships between any two routers by sending hello packets.

QUESTION NO: 10
Which of the following is the correct description of the configuration BPDU generation? (multiple choice)

A. When the root port receives the configuration BPDU, the device where the root port resides will copy a configuration BPDU to each of its designated ports. B. As long as the port is enabled with STP, the configuration BPDU will be sent from the designated port at regular intervals. C. When the designated port receives a configuration BPDU that is worse than itself, it will immediately send its own BPDU to the downstream device. D. The topology of the non-root bridge changes. The BPDU is notified by configuring the BPDU.

Correct Answer: A,B,C
