NEW QUESTION 113
According to this picture, what can we judge? (Multiple choice)

If the routing policy on AS_Path is not configured, then 3002:-4/128 must not originate from AS 65001

R1 does not have routes of 3002:.3/128 and 3002.-4/128

R1 has routes of 3002.-3/128 and 3002:.4/128

If the routing policy on AS_Pash is not configured, then 3002:4/28 must originate from AS 65001

NEW QUESTION 114
Regarding the label space of MPLS, which of the description is wrong?

When the penultimate hop LSR performs label switching, if the value of the label after the exchange is found to be 3, the label will be ejected by default and the packet will be sent to the last hop

1024 or more is the label space shared by dynamic signaling protocols such as LDP, RSVP-TE, MP-BGP, etc.

16~1023 is the label space shared by static LSP and static CR-LSP

If the outgoing label value is 0, the router will directly discard the packet

NEW QUESTION 115
After the cutover is completed, which items generally need to be checked? (Multiple choice)

Software version

Physical topology

Data flow

Control plane entries

NEW QUESTION 116
For the same MAC address, the priority of the manually configured MAC entry is higher than the automatically generated entry.

TRUE

FALSE

NEW QUESTION 117
When deploying BGPIMPLS IPVPN, when two VPNs have a common site, the common site must not use overlapping address spaces with other sites of the two VPNs.

TRUE

FALSE

NEW QUESTION 118
As shown in the figure, the router runs OSPF and Area2 is a completely stub area. Please match the type of LSA contained in each area with the area ID.
Type1 LSA , Type2 LSA , Type3 LSAType1 LSA , Type2 LSA , Types LSA , Type5 LSAType1 LSA , Type2 LSA , Type3 LSA , Type4 LSA , Type5 LSA

NEW QUESTION 119
In the process of daily troubleshooting, engineers may need to check some alarm information of the device.
Turn on the debugging/log/alarm information sent by the terminal display information center by executing the terminal () command.
(Please use English lowercase letters to complete the command, and the command cannot be abbreviated)

monitor

NEW QUESTION 120
(Drag and drop) Please match the following DHCP attack types with corresponding explanations.

NEW QUESTION 121
According to this picture, we can judge:

The system ID of R1 is ee8c.a0c2.bafl

R1 has both leve1-1 and level-1-2 link state information

R1 only has link state information for leve1-2

In the leve1-2 network, there are a total of 8 routers

NEW QUESTION 122
What is the value of OSPF and BFD linkage?

The hello sending interval of OSPF is at the second level, which is faster than BFD inductive link state

The sending interval of BFD packets can reach the millisecond level, which is slower than the OSPF inductive link state

Through the BFD detected at the millisecond level, the OSPF status is associated to achieve the purpose of OSPF quickly inductive link state

Any change in the BFD status will not affect the OSPF neighbor status

NEW QUESTION 123
If the display current-configuration can reach the IS-IS configuration, but there is no IS-IS configuration in the display saved-configuration, what does it mean?

The IS-IS configuration that the Flash is running is not saved to the memory

The running IS-IS configuration in the memory has been saved to the Flash

No IS-IS command is entered

The running IS-IS configuration of the memory is not saved to the Flash

NEW QUESTION 124
EGP authentication can prevent illegal routers from establishing neighbors with BCP routers. BCP authentication can be divided into MD5 authentication and Keychain authentication. Which of the following BGP messages will carry BCGP Keychain authentication information? ((Multiple choice)

Open

Update

Notication

Keepalive

NEW QUESTION 125
Which description is correct about the label encapsulation format in MPLS? (Multiple choice)

The total length of a single MPLS label is 4 bytes (32 bits)

For Ethernet and PPP packets, the label stack is located between the layer 2 header and the data like a “underlay*”: when there is a VLAN tag, the MPLS header is placed between the Ethernet header and the VLAN tag

The S field in the label: 1 bit, used to identify whether the label is the bottom label of the stack, when the value is 1, it indicates the second-to-last label

The TTL field in the label is similar to the TTL (Time To Live.) in the IP packet, and it also has the effect of preventing loops.

NEW QUESTION 126
MPLS is called multi-protocol label switching. Regarding the label description in MPLS, which of the following is correct? (Multiple choice)

MPLS system has a variety of label publishing protocols, such as LDP is a label publishing protocol

The label is carried by the header of the MIPLS message and has a global meaning, that is, the label value of all routers cannot be repeated

A label is an identifier with a fixed length and only local meaning, which is used to uniquely identify the FEC to which a group belongs

MPLS supports single-layer labels as well as multi-layer labels

NEW QUESTION 127
As shown in the figure, all routers run OSPF, because R3 is in the backbone area, so there is no type 3 LSA in the LSDB of R3.

TRUE

FALSE

NEW QUESTION 128
(Connection) The default MPLS label release method and label distribution control method of Huawei routers and label retention methods are respectively
