Correct Answer: C

Question 4

With the increase of business traffic, an enterprise needs to expand the backbone network transmission bandwidth. Which of the following methods can best meet this demand?

B. Modify the routing protocol related to the network layer and change the number of paths for routing protocol load sharing to the maximum value

C. Increase the number of tunnels between backbone network devices and enable HSB protection for these tunnels

D. Increase the number of interconnected links between backbone network devices and deploy link aggregation between backbone network devices

Correct Answer: D

Question 5

In the network shown in the figure, the IP addresses planned for the interconnection interfaces of R1 and R2 have been marked in the figure, but R1 and R2 cannot be Pine connected. Therefore, the network engineer checked the configuration of the R1 and R2 interfaces and judged based on the configuration information that the wrong mask configuration of the R2 interface was the cause of the fault.

A. False

B. True

Correct Answer: A

Question 6

As shown in the figure, VLAN aggregation is deployed in a switching network, where Sub-VLAN
10 and Sub-VLAN 20 are added to Super-VLAN 100. If PC1 and PC2, PC1 and PC3 are to be able to communicate with each other, which of the following descriptions about the L3 Switch interface type and the VLAN that should be allowed is correct?

A. GE0/0/1 and GE0/0/2 are both access ports, and the PVID is set to VLAN10.

B. GE0/0/1 is a Trunk port, allowing VLAN 10 and VLAN 20 to pass; GE0/0/2 is an Access port, and the PVID is set to VLAN 10

C. Both GE0/0/1 and GE0/0/2 are Trunk ports, and only VLAN 10 is allowed to pass.

D. GE0/0/1 is an access port, and its PVID is set to VLAN 10; GE0/0/2 is a trunk port, and VLAN 10 is allowed.

Correct Answer: B

Question 7

In the OSPF network shown in the figure, area 1 is an NSSA area, area 2 is a common area, and R4 imports the external route 10.0.4.4/32. The Router ID of each device is 10.0.XX, where X is the device number.

The "asbr-summary 10.0.4.0 255.255.255.0" command is configured in the OSPF processes of R1 and R3. Which of the following routers have a route entry for 10.0.4.0/24 in their routing tables? (Multiple choice)

A. R2

B. R5

C. R3

D. R1

Correct Answer: A,B

Question 8

Which of the following reasons may cause the local device to be unable to learn the ARP information of the other device? (Multiple choice)

A. Link transmission is unstable or optical power is insufficient

B. The device is attacked by ARP

C. The physical layer of the connection is not normal

D. The address configured on the interface is not in the same network segment as the peer device.

Correct Answer: A,B,C,D

Question 9

When the switch is configured with the port isolation function, by default, different hosts belonging to the same VLAN cannot communicate at Layer 2 and Layer 3.

A. False

B. True

Correct Answer: B

Question 10

If an OSPF router is set as a stub router, which of the following is the link metric in the LSA sent by the router?

A. 100

B. 65535

C. 1

D. 10

Correct Answer: B

Question 11

As shown in the figure, in the OSFF network: Area 1 is the NSSA area, Area 2 is the common area, R4 introduces the external route 10.0.0.4/32, and the Router ID of each device is 10.0.XX, where X is the device number.

The "asbr-summary 10.0.4.0 255.255.0" command is configured in the OSPF processes of R1 and R3. Which of the following descriptions is correct?

A. There is no route entry for 10.0.4.4/32 in R3's routing table.

B. R2 has a route entry for 10.0.4.4/24 in its routing table.

C. R1 routing table has a routing entry for 10.0.4.0/24

D. R3 routing table has a routing entry for 10.0.4.0/24

Correct Answer: B

Question 12

In the network shown in the figure, PC1 and PC2 are required to belong to the same VLAN, but cannot communicate at Layer 2. Which of the following technologies can be used to achieve this?
(Multiple choice)
