Question 1

Which of the following descriptions about the Originator_ID attribute in BGP is correct? (Multiple choice)

A. Originator_ID is a recognized arbitrary attribute

B. When other BGP Speakers receive this route, they will compare the received Originator_ID with the local RouterID. If the two IDs are the same, BGPSpeaker will ignore this route and do not process it.

C. When a route is reflected by RR for the first time, RR adds the Originator_ID attribute to this route to identify the originating router of this route

D. If there are multiple RRs in As, the Originator_ID attribute is created by the first RR

Correct Answer: C,D

Question 2

As shown in the figure, R1 and R2 constitute a VRRP backup group with a VRID of 1. Which of the following descriptions about the VRRP master and backup election process is wrong?

A. After the two devices are initialized, they will first switch to the Backup state

B. Both devices will switch to the Master state after their respective NASTER DoV timers expire

C. Finally, R1 will send a free ARP message

D. In the case of simultaneous startup, R1 switches to the aster state faster than R2

Correct Answer: B

Question 3

Data center equipment can be simply divided into computing equipment, storage equipment and network equipment.
Which of the following is not a network device?

A. Firewall

B. IDS/IPS

C. Server

D. Load balancing

Correct Answer: D

Question 4

As shown in the figure, in the MA network, if R1 must be DR, R2 must be BDR, and R3, R4, and R5 do not participate in the election, then the maximum dr-priority of R1 is (), and the dr-priority of R2 is the maximum is (), the dr-priority of R3 is (), the dr-priority of R4 is (), and the dr-priority of R5 is ().

Correct Answer:

255|254|0|0|0

Question 5

Which of the following description about VRRP is wrong?

A. If the Backup router works in non-preemptive mode, if the Master router does not fail, the Backup router will not become the Master router even if it is subsequently configured with a higher priority

B. If Master already exists, Backup will also preempt

C. VRRP determines the status of each router in the virtual router based on priority

D. When two routers with the same priority compete for Master at the same time, compare the size of the interface IP address, and the one with the larger interface address will be elected as the Master

Correct Answer: B

Question 6

Which of the following descriptions about configuring the set-overload command in IS-IS is correct?

A. This command is used to enable IS-IS to automatically calculate the interface cost according to the bandwidth

B. This command is used to set the overload flag bit of non-pseudo-node LSP

C. This command allows the device to set the time for the system to maintain the overload flag according to the state of BGP convergence

D. This command is used to specify that the Hello message sent after the device restarts carries the SA bit

Correct Answer: B

Question 7

When the payload is an ICMPv6 message, if the extension header is not considered, what is the value of the Next Header field in the IPv6 header?

A. 78

B. 68

C. 55

D. 58

Correct Answer: D

Question 8

Which of the following descriptions of multicast routing is correct? (Multiple choice)

A. Multicast routing protocols are used to establish and maintain multicast routes and forward multicast packets correctly and efficiently.

B. Multicast routing forms a one-way loop-free data transmission path from the data source to multiple receivers, that is, the multicast distribution tree

C. Multicast routing protocols include IGMP protocol

D. Multicast routing protocols are divided into intra-domain multicast routing protocols and inter-domain multicast routing protocols.

Correct Answer: A,B,D

Question 9

After establishing a neighbor relationship between the two DRother routers R1 and 2 in the MA network, execute the [R1] diaplay ospf peer command in R1. At this time, the neighbor status of R2 is displayed as Loading.

A. FALSE

B. TRUE

Correct Answer: A

Question 10

Because multicast data forwarding relies on routing table entries, problems such as loops and suboptimal paths will not occur during the forwarding process.

A. FALSE

B. TRUE

Correct Answer: A

Question 11

The three routers run IS-IS and have established an adjacency relationship. The area numbers and router levels are marked in the figure. If the road between R1 and R2 is interrupted, which of the following statements is correct? (Multiple choice)

A. R1 sets the Age of the LSP generated by R2 to 0

B. The default route in the R2 routing table still exists

C. R1 runs the SPF algorithm to remove R2 from the SPF trunk

D. The default route in the R2 routing table will disappear

Correct Answer: C,D

Question 12

Which of the following log levels are available in the USG series firewalls? (Multiple choice)

A. Informational

B. Monitoring

C. Event

D. Error

E. Emergency

F. Alert

Correct Answer: A,D,E,F

Question 13

The following is the output information of a router. Which is the correct description of this information?

A. The community attribute value carried by the destination network segment 5.1.1.0/24 is no-advertise, indicating that the routing entry cannot be advertised outside the local AS

B. The community attribute value carried by the destination network segment 1.1.1.0/24 is no-export, indicating that the routing entry cannot be advertised to any BGP neighbors

C. The community attribute value carried by the destination network segment 1.1.1.0/24 is no-export, indicating that the routing entry can be advertised to any BGP neighbor

D. The community attribute value carried by the destination network segment 5.1.1.0/24 is no-advertise, indicating that the routing entry cannot be advertised to any other BGP peers

Correct Answer: D

Question 14

Which of the following types of equipment is suitable for Huawei IP wide-area bearer network solution?

A. AirEngine 5760-22w
