QUESTION 22
Which of the following description of the configuration on this switch is correct? (Multiple choice)

To configure the DHCP server and DHCP relay, DHCP must be enabled globally

The configuration in the figure can be achieved

Need to create a remote peer, and then specify the lsr-id of the peer

150

100

QUESTION 29
Regarding BGP/MPLS IPVPN data forwarding, which of the following descriptions is wrong?

data inB, CP/MPLS IP VPNWhen the backbone network is transmitted, it always carries two layers of labels

The inner label when data is forwarded is defined byMP-BGPdistribute

The outer layer label when data is forwarded can beLDPdistribute

PEsend toCEThe data isIPv4Genuine

QUESTION 30
OSPFV2 is an IGP running on an IPv4 network; OSPFV3 is an IGPo running on an IPv6 network. The basic working mechanism of OSPFv3 is the same as that of OSPFV2, such as the election of DR and B, DR. As shown in the figure, an engineer uses 3 routers to test IPv6 services. He wants to realize the interconnection of IPv6 networks by running OSPFV3.
Pass. Which of the following statements about the election of the network DR is correct?

After the network converges, engineers modifyR1the priority is100,R2the priority is10,R3Keep the default value. When the network converges again,R1forDR, R2forB, DR

After the network converges, a new device is added to the broadcast linkR4,R4the priority is150. When the network converges again,R4forDR

After the network convergesR1Power off and restart, when the network converges again,R3forDR

After the network converges,R1forDR

QUESTION 31
In an intra-domain MPLS VPN network, when a data packet enters the public network and is forwarded, it will be encapsulated with two layers of MPLS labels. Which of the following description is wrong about the two layers of labels? (Multiple choice)

The outer label of MPLS VPN is allocated by the LDP protocol or statically, and the inner label is allocated by the MP-BGP neighbor at the correct end.

By default, the outer label is ejected before the packet is forwarded to the last-hop device

The outer label of MPLS VPN is called the private network label. The inner label is called the public network label.

The outer label is used to correctly send the data packet to the corresponding VPN on the PE device

QUESTION 32
According to this picture, what can we judge? (Multiple choice)

R1’s GE0/0/1 must have Leve1-2 capability

R1’s GE0/0/0 must have the Leve1-2 capability

There must be an LSDB of Leve1-2 on R1

R1 has 2 IS-IS neighbors

QUESTION 33
A router is running OSPF, and the output information is as shown in the figure. Which of the following statements is correct?

The type of the LSA is AS-externa1-LSA

The destination network described by this LSA is 10.0.23.0/24

The LSA in the figure is generated by this router

This device is ABR

QUESTION 34
(Multiple Choice) Which LSAs in OSPFv3 can be flooded in an area?

Link-LSA

Inter-Area-Router-LSA

Inter-Area-Prefix-LSA

Intra-Area-Prefix-LSA

QUESTION 35
As shown in the figure, R1, R2, R3, and R4 are in the same PLs domain, and LDP is used to distribute IPLS labels between devices.
R4 is the Egress LSR of the FEC 4.4.4.0/24. If you want to achieve R1 access 4.4.4.0/24, R4 does not need to query the label table but can know the forwarding priority of the data, then the outgoing label of R3 for the FEC should be:____. (Please fill in the Arabic numerals directly, without symbols)

(0)

QUESTION 36
In OSPFv3, the LSA whose propagation range is an area has () types. (Fill in Arabic teaching characters only)

129

QUESTION 37
Which of the following statements about the MP_REACH_NLRI attribute of BGP4+ is correct? (Multiple choice)

The length of the next hop address can be 16 or 3

The AFI (address family) value is 2, which represents IPv6

The NLRI field carries IPv6 routing prefix and mask information

When the length of the next hop address is 16, the Network Address of Next Hop carries the link local address

QUESTION 38
The ipv6 enable topology standard has been set in the S-IS protocol view. The meaning of this command is:
Pv4 shares a topology with IPv6.

True

False

QUESTION 39

QUESTION 40
A network engineer entered the following information when troubleshooting OSPF faults. Based on this, you can judge what causes the adjacency relationship to fail to be established normally?

Authentication passwords do not match

Inconsistent area type

Hell. Inconsistent message sending interval

interfaceIPInconsistent address masks

QUESTION 41
Which of the following statement is wrong?

LSPs established by statically assigning labels can also be dynamically adjusted according to changes in the network topology, without administrator intervention

The principle to be followed for manual label allocation is: the value of the outgoing label of the upstream node is the value of the incoming label of the downstream node

LSP is divided into static LSP and dynamic LSP. The static LSP is manually configured by the administrator, and the dynamic LSP is dynamically established using the label protocol

Dynamic LSP is dynamically established through label distribution protocols, such as MP-BGP, RSVP-TE, LDP
