Question 1

IGMP SSM Mapping By statically binding multicast sources to multicast groups, IGMPv1 with IGMPv2 group members can also access SSMMulticast network. The following about IGMP SSM Mapping statementMistakeYes? (single choice)

ASSM The address of the multicast group is 232.0.0.0~232.255.255.255

BIGMP SSM Mapping Does not handle IGMPv3 report message. In order to ensure that any version of IGMP runs on the same network segment hosts can get SSM service, you need to run IGMPv on the interface of the multicast router connected to the network segment where the member host is located3

CIf IGMP is not enabled SSM Mapping Features, IGMPv1 and IGMPv2 Neither supports the deployment of SSM The multicast

Doption of the mode is missing. The ABC option is correct. Anyway, ABC is not selected.

Answer : A, B, C

Question 2

Router A has an IP routing entry with the destination network segment 10.0.0.1/32 and the outbound interface GigabitEthernet0/0/1. Now add the following configuration: acl numberr 2000

rule 10 permit source 10.0.1.1

traffic classifier test if-match acl 2000 traffic behavior test remark dscp cs3

traffic policyy test classifier test behavior test interface GigabitEthermet0/0/1

ip address 10.0.12.1 255.255.255.0

traffic-policy test outbound

Assuming that router A receives a packet with destination IP 10.0.0.1, which of the following statements are correct:

AIf the source IP address of the packet is 10.0.1.2, it can be forwarded, and at the same timeDSCP field is marked as CS3

BIf the packet source IP address is 10.0.1.1, it can be forwarded, and the DSCP field is marked as CS3

CIf the source IP address of the packet is 10.0.1.2, it cannot be forwarded

DIf the source IP address of the packet is 10.0.1.2, it can be forwarded, and at the same timeDSCP field remains unchanged

Answer : B, D

In the test policy, if the matching source address is 10.0.1.1, the remarked dscp value is cs3. If it does not match, it will be forwarded normally.

Question 3

Which of the following LSAs are only spread within a single area? (multiple choice)

AAS External LSA

BRouter LSA

CNetwork LSA

DSummary LSA

Answer : B, C, D

Question 4

Configured under an interface: isis timer hello 5 level-2, is the following statement correct?

AThe CSNP packet sending interval of Leve1-2 of this interface is 5s

BThe hello packet sending interval of the interface Leve-1 and Leve1-2 is 5s

CThe hello packet sending interval of the interface Leve1-1 is 5s

DThe hello packet sending interval of the interface Leve1-2 is 5s

Answer : D

Question 5

You need to configure policy routing on the router to specify that specific traffic should be forwarded through an interface. When using policy-based routing, which two

The most typical information that can be used to forward traffic along a specific path?

ApacketTTL and source IP address

Bsource IPaddress and Layer 2 source address

CSource IP address and specific protocol(such as FTP, HTTP Wait)

DType of Service header and message length

Answer : C

Question 6

Which of the following descriptions about ISIS' route penetration is correct?

AISIS's route penetration is used to prevent routing loops

BRoute penetration by ISIS will not cause neighbor flapping.

CISIS routing penetration can be deployed on routers at the level of Leve1-1.

DIn the route infiltration of ISIS, the route before infiltration cannot be an aggregate route.

EISIS routing penetration can be used in an IPv6 environment.

Answer : B, E

Question 7

In the intra-domain MPLS BGP VPN network, when the data packet enters the public network for forwarding, it will be encapsulated with two layers of MPLS labels. Which of the following descriptions about the two layers of labels is wrong?

ABy default, the router assigns the same label value to all VPNv4 routes destined for the peer PE.

BThe egress PE uses the inner layer label when judging which egress CE the message should be sent to.

CMPLS BGP VPN uses two layers of labels, the public network label (also called the outer label) and the private network label (also called the inner label).

DThe private network label is used by NP-BGP It is carried and distributed when the route is passed, and the public network label is set by LDP Agreement distribution.

Answer : A
