NO.154 Access control refers to restricting or blocking specific access traffic based on the needs of business management and control on the basis of reachable network routes.

True

False

NO.155 A campus deploys OSPF to realize network interworking. The LSDB of R2 is shown in the figure.

What information can be derived from this LSDB? (Multiple choice)

There is no Type3 LSA in Area1

Area1 is the NSSA area

R2 converts the default route of Type7 LSA to the default route of Type5 LSA

R2 delivers the default route in the OSPF process

NO.156 As shown in the figure, in a medium-sized network, in order to improve the reliability of RR, BGP generally deploys double R.

When deploying dual EE, the Cluster IDs of the two RRs are generally set to be the same. What is the reason for this?

Prevent RR from receiving too many routes and causing insufficient memory

Prevent suboptimal

Prevent loops

Prevent the client from receiving too many routes and causing insufficient memory

NO.157 As shown in the figure, OSPF is enabled on all interfaces of the router. The ip address marked in the figure is the IP address of the loopback0 interface. The Loopback0 of R1, R2, and R3 is advertised in area 1, and the Loopback0 of R4 is advertised in area 0, Loopback0 of R5 announces which of the following functional addresses in area 2 can ping each other?

10.0.3.3 and 10.0.5.5

10.0.4.4 and 10.0.2.2

10.0.2.2 and 10.0.3.3

10.0.2.2 and 10.0.5.5

NO.158 According to this figure, we can judge:

R1 is configured with zone authentication

The device type of R1 is Level-1

The device type of R1 is Leve-2

R1 sets routing domain authentication

NO.159 The default MPLS label publishing mode, label distribution control mode and label retention mode of Huawei routers are:

Label release method downstream independent method, the label distribution control method free method, the label retention method independent method.

Label release method free method, label distribution control method independent method, label retention method downstream independent method

Label release method downstream independent method, label distribution control method independent method, label retention methodm free method

Independent method of label release method, free method of label distribution control method, and downstream independent method of label retention method

NO.160 When deploying BGPIMPLS IPVPN, when two VPNs have a common site, the common site must not use overlapping address space with other sites of the two VPNs.

TRUE

FALSE

NO.161 In the scenario of multi-level RR, a large number of secondary RRs will be connected to the primary RR, which may cause the BGP routing table of the primary RR to overflow. What method can be used to reduce the risk of overflow of the BGP routing table of the level RR?

ORF

Route Aggregation

Routing Control

Set the same Cluster-lD

NO.162 Which of the following sequences can be matched by the regular expression 100.S? (Multiple choice)

100

1000

10000

1001

NO.163 Which of the following description of TTL in MPLS Header is correct?

TTL that acts like an IP header

To control label distribution

Limit the LSR

Control of upstream equipment for label distribution

NO.164 Which of the following limitations of traditional networks do not include?

The speed of new network service upgrade is slow.

The implementation of network protocols is complex, and the operation and maintenance are difficult.

Different manufacturers’ equipments have similar operation commands, and the differences are small and easy to operate.

The adjustment capability of the traffic path is not flexible enough.

NO.165 All routers run OSPF as shown.

Which of the following statements is correct?

R2 generates Router LSAs in both area 1 and area 0

R2 forwards the Router LSA generated by R3 to R1

R2 forwards the Router LSA generated by R1 to R3

R2 only generates Router LSA in area 0

NO.166 Traditional BGP-4 can only manage IPv4 unicast routing information. MP-BGP extends BGP-4 in order to provide support for various network layer protocols. MP-BGP uses address family to distinguish different network layer protocols. Which of the following address families are currently supported? (Multiple choice)

BGP-VPNv4 address family

BGP-IPv6 Unicast Address Family

BGP-IPv4 broadcast address family

BGP-MP instance IPv6 address family

NO.167 Which of the following is not a preliminary preparation for the cutover plan?

Field Defence

Cutover target

Existing network root description

Risk Assessment

NO.168 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 32

AF (address family) value is 2, representing 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
