NO.104 After configuring NAPT, it is found that some internal network addresses can always ping the external network, while others cannot. The possible reasons are ______.

ACL setting is incorrect

The NAT address pool has only one address

Insufficient NAT device performance

NAT configuration does not take effect

NO.105 After enabling DHCP on the router RTA, you need to set the address range of the address pool to 192.168.1.0/24, and the default gateway address assigned to the host is 192.168.1.254.
Which of the following configurations can meet these requirements? (multiple choice)

[Router] dhcp server ip-pool 0

[Router-dhcp-pool-0] network 192.168.1.0 mask 255.255.255.0

[Router-dhcp-pool-0] gateway-list 192.168.1.254

[Router-dhcp-pool-0] dns-list 192.168.1.10

NO.106 The following statement about WAN is wrong. ______.

The HDLC protocol only supports point-to-point links, not point-to-multipoint links.

The HDLC protocol can be encapsulated on the synchronous link or on the asynchronous link. Only supports synchronization

When the CE1/PRI interface uses E1 working mode, it is equivalent to an interface with no time slot division and a data bandwidth of 2Mbps. Its characteristics are the same as the synchronous serial port, supporting PPP, frame relay, LAPB and X.25 And other data link layer protocols, supporting network protocols such as IP and IPX.

When the CE1/PRI interface uses the CE1/PRI working mode, it is physically divided into 32 time slots, the corresponding numbers are 0~31, of which time slot 0 is used to transmit synchronization information.

NO.107 The IP address 10.0.10.63 and the mask 255.255.255.224 represent a ______.

host address

Network address

Broadcast address

None of the above

NO.108 The correct statement about the STP protocol is ______. (Multiple choice)

The BridgeID value is a combination of the priority of the bridge and the MAC address of the bridge. The front is the priority, and the back is the MAC address.

The default priority value of the H3C Ethernet switch is 32768

The smaller the priority value, the lower the priority

When the priority is the same, the smaller the MAC address, the higher the priority

The one with the higher BridgeID value will be selected as the root bridge

NO.109 The TCP protocol uses ______ to distinguish different connections.

Port number

Port number and IP address

Port number and MAC address

IP address and MAC address

NO.110 A DNS client queries the local domain name server for the IP address of www.sina.com.cn, and the local domain name server usually responds by means of DNS query?

Recursive query

Iterative query

Reverse query

Fuzzy query

NO.111 If you want the current configuration to continue to take effect after the system restarts, you should use the _______ command to save the current configuration to the configuration file before restarting the device. (Please write full order)

NO.112 Divide a class B network segment into subnets. If the subnet mask is 19 bits, the maximum number of subnets that can be divided is ___. (Please fill in Arabic numerals)

NO.113 The 802.11b protocol defines 14 channels in the 2.4GHz frequency band, and there is overlap in the frequency spectrum between adjacent channels.
In order to maximize the use of frequency band resources, which set of channels can be used for wireless coverage?

1, 5, 9

1, 6, 11

2, 6, 10

3, 6, 9

NO.114 In the process of establishing a PPP session, when authentication is set but the authentication fails, the PPP link enters the ______ phase.

Establish

Network

Authentication

Dead

Terminate

NO.115 The XYZ company network is shown in the figure.

There is no logical interface configured on the Router; all hosts can communicate normally. Then there are ___ broadcast domains in this network. (Please fill in Arabic numerals)

NO.116 The IP address 10.0.10.32 and the mask 255.255.255.224 represent a ______.

host address

Network address

Broadcast address

None of the above

NO.117 The broadcast address of the natural classification network segment corresponding to the IP address 125.1.1.1 is ____________.

125.255.255.255

NO.118 To view the debug information of NAT packets, you should use the ______ command to turn on the debug information and output it to the display.

terminal debugging debugging nat

terminal monitor terminal debugging debugging nat packet

terminal monitor terminal debugging debug nat

NO.119 The common fields of UDP protocol and TCP protocol header are ______. (Multiple choice)

Source IP address

Flow control

checksum

Serial number

Destination port

Source port

NO.120 The following description of Trunk ports and links is wrong. ______. (Multiple choice)

The PVID value of the Trunk port cannot be modified

When the Trunk port sends a data frame, if the data frame does not have a VLAN ID, add the corresponding PVID value to the data frame as the VLAN ID

Trunk link can carry data frames with different VLAN IDs

The data frames transmitted on the Trunk link are all with VLAN ID

NO.121 The customer’s two MSR routers MSR-1 and MSR-2 are interconnected back-to-back through their respective S0/0 interfaces. The frame relay protocol started and encapsulated between the S0/0 interfaces of two MSR routers, where MSR-1 is the frame relay DCE side, and MSR-2 is the frame relay DTE side.
In order to save resources, frame relay sub-interfaces are configured on both routers, which are configured as follows:
MSR-1:
interface Serial0/0.40 p2p
fr dlci 222
ip address 30.2.2.2 255.255.255.252
MSR-2:
interface Serial0/0.100 p2p
fr dlci 222
ip address 30.2.2.1 255.255.255.252
Based on this configuration, you can guess ______. (Multiple choice)

Can’t ping through MSR-1 30.2.2.1

You can ping through MSR-1 30.2.2.1

The frame relay sub-interfaces of the two routers cannot communicate with each other because fr map is not configured

The frame relay sub-interfaces of the two routers cannot communicate with each other because their sub-interface numbers are inconsistent
