NO.76 ip ip-prefx List1 index 10 permit 10.1.0.0 24 greater-equal () less-equal 32 means that the first 24 bits of the matching network address are the same as 10.1.0.0, and the network mask length is greater than or equal to 26 and less than or equal to 32. (Use Arabic numerals)

2632

NO.77 Regarding the description of VRRP load sharing, which one is correct? (Multiple choice)

Load sharing method refers to the establishment of two or more backup groups, and multiple routers carry services at the same time

When configuring priorities, the VRRP masters of the three virtual routers can be on different routers

Multiple virtual routers can be created on one interface of the router, so that the router can be used as a master router in one virtual router, and at the same time as a backup router in other virtual routers.

The load sharing method means that multiple routers undertake services at the same time, so the load sharing method requires two or more virtual routers

NO.78 Which is wrong about the NDP address function in the following description?

Two ICMPv6 messages, neighbor solicitation and neighbor advertisement, are used in the address process

The address realizes the function from the IPv6 address to the link layer address

When sending a neighbor solicitation message, the destination address must be the neighbor’s solicited node multicast address

When sending a neighbor solicitation message, the source address must be the link-local address of the local interface

NO.79 What parameters can the DHCPv6 server assign to the DHCPv6 client? (Multiple choice)

STP server address

DNS server address

Gateway address

IPv6 address prefix

NO.80 The following information is the output of a router, which of the following regarding the information is true?

The community attribute value carried by the destination network segment 1.1.1.0/24 is no-export, indicating that the route entry cannot be advertised to any BGP neighbors

The community attribute value carried by the destination network segment 5.1.1.0/24 is no-advertise, indicating that the route entry cannot be advertised to any other BGP peers

The community attribute value carried by the destination network segment 1.1.1.0/24 is no-export, indicating that the route entry can be advertised to any BGP neighbor

The community attribute value carried by the destination network segment 5.1.1.0/24 is no-advertise, indicating that the route entry cannot be advertised outside the local AS

NO.81 When pinging the IP address of a certain interface of the firewall on the firewall, these messages will be handed over to the internal module of the firewall for processing and will not be forwarded.

TRUE

FALSE

NO.82 How long is the default DHCP address pool lease period?

1 month

1 hour

1 week

1 day

NO.83 As shown in the figure, there are the following configurations under BGP, which of the following descriptions are wrong? (Multiple choice)
[HUAWEI-bgp] timer keepalive 30 hold 90
[HUAWEI-bgp] peer 1.1.2 timer keepalive 10 hold 30

Timer takes the minimum value, so the final result is that the timer value of peer 1.1.1.2 takes keepalive10 hold 30

Peer configuration takes precedence, so the final result is that the timer value of peer 1.1.1.2 takes keepalive 10 hold 30

Global configuration takes precedence, so the final result is that the timer value of peer 1.1.1.2 takes keepalive 30 hold 90

The default configuration is timer Keepalive 60 hold180, so pee r1.1.12 has a faster detection speed for Peer connection failure than the default value

NO.84 Which of the following description about BGP reliable routing updates is correct?

BGP works on top of UDP, and the transport layer protocol is 179

BGP does not need to periodically advertise routing information

BGP sends complete routing table information every time when a route is updated

BGP uses multicast updates

NO.85 IGMPv1 defines a mechanism for electing queriers when there are multiple routers in a shared network.

TRUE

FALSE

NO.86 In the OSPF routing protocol, the types of LSA involved in the calculation of intra-area routes are only Router LSA, Network LSA and Summary LSA.

True

False

NO.87 In the network shown in the figure, R1 and R2 run IS-IS and establish an adjacency relationship. The Loopback0 interface of R2 enables IS-IS, and the Loopback3 interface of R2 does not enable IS-IS. Do as follows in the IS-IS process of R2 the configuration shown in figure, which of the following statement is correct? (Multiple choice)

The 10.0.2.2/32 and 10.0.2.3/32 routes do not exist in the routing table of R1

There is no route 10.0.2.3/32 in the R1 routing table

There is a 10.0.2.2/32 route in the routing table of R1

There is a 10.0.2.3/32 route in the routing table of R1

NO.88 Which of the following SA descriptions of various messages are wrong? (Multiple choice)

DD only contains the summary information of LSA, that is, it contains LS Type, LS ID, Advertising Router and LS Sequence Number

LS Request message only has LS Type, Ls ID and Advertising Router

NO.91 Which of the following description of roaming is wrong? (Multiple choice)

The working channels of the two APs before and after roaming must be the same
