1. There is a message in the BGP protocol that is periodically sent between BGP neighbors to maintain the neighbor relationship. This message is:

Update

Hello

open

Keepalive

2. As shown in the figure, in the network running the RSTP protocol, the original root port of SWC fails and the port is in the Down state. At this time, which of the following processes will the network go through to achieve stability?

The standby port on the SWC becomes the new root port and enters the Forwarding state after going through the Learning state

SWC re-elects the root port and directly enters the Forwarding state

The standby port on the SWC becomes the new root port and directly enters the Forwarding state

SWC re-elects the root port and enters the Forwarding state after Learning

3. Which of the following description of OSPF neighbor relationship and adjacency relationship is correct?

The adjacency relationship is maintained by OSPF DD packets

OSPF routers must establish an adjacency before exchanging Hello packets

The neighbor relationship is selected from the adjacency relationship and formed to exchange routing information

Not all neighbor relationships can be adjacencies

4. Which of the following is not the main function of NDP?

Path MTU Discovery

Neighbor Status Tracking

Duplicate address detection

Address

5. 1. About the description about the OSPF calculating the shortest path tree stage, which is the correct?

The first stage calculates the Stub network segment, and the second stage calculates the router node and Transit network segment.

The first stage calculates routing nodes and Transit network segments, and the second stage calculates Stub network segments.

The first stage calculates the stub segment, and the second stage calculates the routing node.

The first stage calculates the routing nodes, and the second stage calculates the Stub network segment.

6. Compared with routers and switching machines, what is the unique forwarding module of the firewall?

Switch fabric board

MPU

LPU

SPU

7. A certain router runs IS-IS, and its output information is shown in the figure. Which of the following statements is correct?

The cycle of sending llH on the s4/0/0 interface is 30s

The circuit-level1 of the s4/0/0 interface is Level-1

The Cost value of the s4/0/0 interface is 20

The s4/0/0 interface supports IPv6

8. What are the key components of building an IP wide-area bearer network solution together with Huawei NetEngine intelligent routers?

iMaster NCE-Fabric

iMaster NCE-IP

iMaster NCE-Campus

iMaster NCE-WAN

9. The MAC address of a certain PC is 5489-98FB-65D8. The administrator wants this PC to obtain the specified IP address 192.168.1.11/24 from the DHCP server, so the command configured by the administrator should be:

dhcp static-bind ip-address 192.168.1.11 24 mac-address 5489-98FB-65D8

dhcp server static-bind ip-address 192.168.1.11 mac-address 5489-98FB-65D8

dhcp server static-bind ip-address 192.168.1.11 255.255.255.0 mac-address 5489-98FB-65D8

dhcp static-bind ip-address 192.168.1.11 mac-address 5489-98FB-65D8

10. Which of the following statement about OSPF neighbor information is wrong?

The router id of the neighbor is 2.2.2.2

This router is the Master

The address of DR is 10.1.1.1

The router id of this router is 1.1.1.1

Page 2 of 3

11. The BGPAS_PATH attribute is an optional transition attribute.

True

False

12. When OSPF runs in a broadcast network, it is necessary to elect DR and BDR.

So, in which of the following states, the election of DR and BDR will be carried out?

2-way status

Exchange status

Full status

Init state

13. Regarding the description of configuring the security level of the security zone of the firewall, the error is:

In the same system, two security zones are not allowed to configure the same security level

Security levels can only be set for custom security areas

Once the security level is set, it is not allowed to change

The newly created security area, the system defaults its security level to 1

14. Regarding the description of IGMP Snooping-working mechanism, which is the correct?

The layer 2 switch establishes and maintains the PIM routing table on the layer 2 by continuously monitoring IGMP messages.

When IGMP Snooping is not running, the multicast message will be broadcast on the second layer. After running IGMP Snooping, the message will no longer be broadcast on the second layer, but will be multicast on the second layer.

If the host sends an IGMP leave message, the switch will add the host to the corresponding multicast table.

If the host sends an IGMP host report message, the switch will delete the multicast entry corresponding to the hos.t

15. As shown in the figure, the stateful inspection firewall will forward the packet because the packet conforms to the firewall session state.

True

False

16. As shown in the figure below, the firewall receives a message from PC1 to PC2 , which of the following statements is correct ?

The packet cannot match the security policies rule1 and rule2, it will match the default policy of the firewall, and the firewall will forward the packet

The default security policy of the firewall is match all, and the action is Deny

The message will match the new security policy rule2, and the firewall will forward the message

The message will match the security policy rule 1

17. The following is part of the output information of the router RTB. The wrong description of the output information is:

The host to send the last Report message is 225.1.1.2

The number of dynamically joined multicast groups on the interface is 1

The display igmp group command is used to view IGMP multicast information, including the information of the multicast group dynamically joined through the member report and the multicast group statically joined through the command line

The joined multicast address is 255.1.1.2

18. As shown in the figure, the stateful inspection firewall will forward the second TCP three-way handshake message in the figure.

True

False

19. As shown in the picture, which of the following statements is correct?

R1 and R2 can establish an adjacency relationship, but cannot complete route calculation.

R1 and R2 can establish an adjacency relationship and complete route calculation.

R1 and 2 cannot establish an adjacency system, because the network configuration of the interface is inconsistent.

R1 and R2 cannot establish an adjacency relationship because the OSPF process numbers are inconsistent.

20. Regarding the special area of OSPF, the wrong description is:

Totally Stub Area allows the ABR to advertise the default three-type LSA, but does not accept five-type LSA and refined three-type LSA

The difference between the NSSA Area and the Stub area is that this area allows the introduction of external routes of the autonomous system, and the ABR issues an LSA7 advertisement to this area

The difference between the Stub Area and the Totally stub area is that the Stub area allows fine-grained routing information between areas.

The difference between the Totally Stub area and the NSSA area is that the Totally Stub area does not accept inter-domain routing information

Page 3 of 3

21. Which of the following tools is used to filter routing information and set routing attributes for filtered routing information?

route-policy

as-path-filter

policy-based-route

IP-prefix

22. Regarding the description of network address port translation (NAP ) and network address translation only (No-PAT), which of the following statements is correct?

No-PAT supports protocol address translation at the network layer

No-PAT only supports protocol port translation at the transport layer

After NATP conversion, for external network users, all packets will only come from the same IP address

NAPT only supports protocol address translation at the network layer

23. By default, on a router running IS-IS in a broadcast network, how many seconds does DIS send CSNP messages?
