NEW QUESTION 116
In intra-domain MPLS VPN networks, data packets will be encapsulated with two layers of MPLS when they enter the public network and are forwarded.
label, the description of the two-layer label in the following options is wrong

MPLS VPNThe outer label is made byLDPprotocol or statically assigned, the inner label is assigned by the correct end MP-BGPassigned by neighbors

MPLS VPNEThe outer layer label is called the private network label, and the inner layer label is called the public network label

By default, the outer label is singled out before the packet is forwarded to the last hop device

Layer labels are used inPEThe device sends the packet correctly to the correspondingVPNmiddle

NEW QUESTION 117
MPLS supports nesting of multiple labels. After receiving an MPLS packet, a device first processes the label next to the Layer 2 header, that is, the top MPLS label.

TRUE

FALSE

NEW QUESTION 118
As shown in the figure, private network routing information is exchanged between PE1 and PE2 and their respective CEs through OSPF, and the same DomainlD is set on both PE1 and PE2. When routes are imported from BGP to OSPF on PE2, it is possible that Which of the following types of SAs are passed to CE2?

Typel LSA

Type3 LSA

Type7 LSA

Type5 LSA

NEW QUESTION 119
A park deployed IPv6 for business testing. There are 4 routers (R1, 22, R3 and R4) in this network, running OSPFv3 to realize the interconnection of IPv6 network. There is a new router R5 that needs to be connected to the network for testing. An engineer introduced a direct route in the OSPFvV3 process of R4 to realize that the devices in the campus network can access the GE0/0/1 port address of R5. Which of the following descriptions of the scene are correct? (Multiple choice)

R2 will generate a Type4 LSA and only flood in Area 0

R4 will generate an IPv6 routing prefix introduced by Type5 LSA description

R2 will generate a Type4 LSA describing the Router ID of R4

R4 will generate a Type5 LSA and only flood in Area 1

NEW QUESTION 120
Fill in Blanks
The configuration shown is performed on R2 to filter all incoming routes. Suppose there is a BGP route with the AS_Path attribute of [100200300400] on R1 that needs to be sent to R2. Please help the network administrator to adjust the AS order in the AS_Path attribute of the route on R1 to ensure that the route entry will not be filtered by the routing policy of R2____, ____, ____, ____.

100 This space corresponds to the [A] space in the routing policy
200 This space corresponds to the [B] space in the routing policy
300 This space corresponds to the [C] space in the routing policy
400 This space corresponds to the [D] space in the routing policy

NEW QUESTION 121
In the absence of a header, the Domain ID of each OSPF process running on the router and the process ID of the process Be consistent and can be modified under the process through the domain-id command

True

False

NEW QUESTION 122
ping -a X-c Y-s z -vpn-instance M 10.5.16.2, what is the meaning of this command is? (Multiple choice)

The ping sends Y ICMP requests

The ICMP request of this ping, the packet size is Z (excluding IP and ICMP header)

The source IFP address of the ping packet is X

The ping packet belongs to VPN instance M

License information

Patch information

The software version the device is running

Whether the configuration is saved

NEW QUESTION 124
The RR rules for advertising routes break the IBGP split horizon rules, so it may cause loops in the AS.

Cluster List

Originator ID

Next hop

AS-PATH

NEW QUESTION 125
As shown in the figure, the entire network of a certain company uses OSPF to get through the network. However, RouterS and RouterE cannot establish an OSPF neighbor relationship. When detecting OSPF failures, network administrators can execute the display ospf 100 () interface GEO/0/1 command on RouterS to obtain error-related information. Users can perform OSPF failure diagnosis based on this information. (Please use English lowercase letters to complete the command, and the command cannot be abbreviated)
