A. FALSE

B. TRUE

Correct Answer: B

Question 2

Router R1 and Router R2 run BGP. Both routers are in AS65234. Router R2's route exists in router R1's BGP routing table, but not in router R1's IP routing table. So what caused the problem to happen?

Question 3

When the ACL in the RP has multiple matching rules (rules) , which of the following statements is true about the matching order? ( confirmed)

A. By default, match pe first rmit, then match the order of deny.

B. There is only one matching order and cannot be modified.

C. By default, matching is performed according to the "depth first" principle.

D. By default, according to Rule-ID, matching from small to large.

Question 5

Which of the following statements about IPSG technology is correct?

A. IPSG can perform binding table matching check on IP packets entering and leaving the interface.

B. ip source checkk user bind checkk The item command is used to configure IP packet inspection items based on VLAN or interface.All static entries take effect.

C. On Huawei routers, IPSG can be configured on VlanifFeatures.

D. If an interface is configured asDHCP Snooping Trust interface, the interface can normally receive the DHCP response from the DHCP server. ACK, DHCP NAK and DHCP Offer packets, other untrusted ports cannot receive these packets normally.

Correct Answer: D

Question 6

In OSPFv3, what is the LSA whose flooding range is the entire autonomous system?

A. Link-LSA

B. Intra-Area -Prefix-LSA

C. Inter-Area-Prefix-LSA

D. AS-external -LSA

Correct Answer: D

Question 7

The topology is as follows,R1 can access the Internet through R2 and R3, RI and R2, An EGP connection is established between R1 and R3. R2 and R3 belong to the same AS. They advertise default routes through BGP respectively. It is required that the traffic from R1 to access the Internet prefers R2. The following methods can be implemented:

A. R2 specifies that peer R1 sets the MED attribute to 150 in the export direction

B. R2 specifies that peer R1 sets the local priority in the export direction to 150

C. R1 specifies that the peer R3 sets the MED attribute to 150 in the import direction

D. R1 specifies that peer R2 sets the local priority to 150 in the import direction

Question 8

During ISIS's broadcast network database synchronization process, which of the following statements is true?
(single choice)

A. R2 acts as DIS, and the Hello time is three times that of ordinary routers.

B. R2 as DIS will not receive PSNP requests from other routes.

C. R1 and R3 maintain database consistency by periodically sending PSNP requests.

D. As DIS, R2 periodically sends CSNP.

Correct Answer: D

Question 9

The two routers in a company are configured as follows. The following statements about the R1 routing table are correct:(single choice)

A. if putR1 The ISIS protocol priority is adjusted to 5, thenThe IP routing entry with the destination network segment 10.0.2.2/32 on R1 is generated by ISIS

B. if putR2 The ISIS protocol priority is adjusted to 5, thenThe IP routing entry with the destination network segment 10.0.2.2/32 on R1 is generated by ISIS

C. only putR2 The ISIS protocol priority is adjusted to 5,Only the IP routing entry with the destination network segment 10.0.0.2/32 on R1 will be generated by OSPF

D. if putR1 The ISIS protocol priority is adjusted to 5, thenThe IP routing entry with the destination network segment 10.0.22/32 on R1 is generated by OSPF
