NO.113 The role of link aggregation is ______.

Data load balancing can be realized.

Increased link reliability between switches.

Can avoid switching network loops.

NO.114 The customer’s network connection looks like:
N1—–MSR-1—–MSR-2—-MSR-3—–N2
The following static routes are configured on MSR-1:
ip route-static 192.168.100.0 255.255.0.0 null0
Then the correct interpretation of this route is ______. (Multiple choice)

On this router, all packets whose destination address belongs to 192.168.100.0/16 will be discarded only if this route is matched

In some cases, this route can avoid loops

The static route always exists in the routing table

If this static route is matched, the packet will be discarded and no information will be returned to the source address

NO.115 The functions implemented by the IPv6 Neighbor Discovery Protocol include _____. (Multiple choice)

Address resolution

Router discovery

Automatic address configuration

Establish a Master/Slave relationship

Duplicate address detection

NO.116 Two empty-configured MSR routers RTA and RTB are interconnected back-to-back through their Serial1/0 interfaces. Do the following configuration on the two routers:
RTA: skip
[RouterA-Serial1/0] link-protocol fr ietf
[RouterA-Serial1/0] ip address 10.1.1.1 30
[RouterA-Seria11/0] fr map ip 10.1.1.2 30
RTB: [RouterB-Serial1/0] link-protocol fr ietf
[RouterB-Serial1/0] interface serial0/0.1
[RouterB-Serial1/0.1] ip address 10.1.1.2 30
[RouterB-Serial1/0.1] fr map ip 10.1.1.1 30
The physical link between the routers is good, so the correct statement below is ______. (Multiple choice)

DLCI is not configured on the two routers, and RTB cannot be pinged on RTA

Can’t ping 10.1.1.2 on RTA

You can ping 10.1.1.2 on RTA

In the above configuration, if you only change the type of sub-interface serial0/0.1 on RTB to P2MP, then you cannot ping 10.1.1.2 on RTA.

In the above configuration, if you only change the type of sub-interface serial0/0.1 on RTB to P2MP, then you can ping 10.1.1.2 on RTA

NO.117 Which part of the subnet division technology is implemented on the basis of the natural classification of IP address division?

Network number part

host number part

Subnet number part

prefix part

NO.118 It is required to set a subnet mask to divide the Class B network 172.16.0.0 into as many subnets as possible. Each subnet requires 15 hosts, so the subnet mask should be _____. (Dotted decimal format) slightly

255.255.255.224

NO.119 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.120 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.121 The following statement about the functions of each layer of the OSI reference model is wrong.

The physical layer refers to the original bit stream transmitted on the communication channel (Channel), which defines the mechanical and electrical functions and procedures required for data transmission.

The network layer decides the best route for transmitting the message. The key issue is to determine how the data packet is routed from the source to the destination.

The basic function of the transport layer is to establish and maintain virtual circuits, perform error checking and flow control.

The session layer is responsible for data format processing, data encryption, etc.

The application layer is responsible for providing network services for applications.

NO.122 The following statement about the functions of each layer of the OSI reference model is correct. ______. (Multiple choice)

The network layer decides the best route for transmitting the message. The key issue is to determine how the data packet is routed from the source to the destination.

The basic function of the transport layer is to establish and maintain virtual circuits, perform error checking and flow control.

The session layer is responsible for data format processing, data encryption, etc.

The application layer is responsible for providing network services for applications.

NO.123 The following routing information is seen on the MSR router running RIP:
<MSR>display ip routing-table 6.6.6.6
Routing Table: Public
Summary Count: 2
Destination/Mask Proto Pre Cost NextHop Interface
6.0.0.0/8 RIP 100 1 100.1.1.1 GE0/0
6.6.6.0/24 Static 60 0 100.1.1.1 GE0/0
At this time, the router receives a data packet with a destination address of 6.6.6.6, then ______.

The packet will first match the RIP route in the routing table because its mask is the shortest

The packet will first match the static route in the routing table because of its high priority

The packet will preferentially match the static route in the routing table because its metric value is the smallest

The packet will preferentially match the static route in the routing table because it has the longest mask

NO.124 The number of available host addresses contained in the natural classification network segment corresponding to the IP address 165.110.20.67 is. (Please fill in Arabic numerals)

65534

NO.125 It is required to set a subnet mask to divide a class B network 172.16.0.0 into as many subnets as possible. Each subnet requires 500 hosts, so the subnet mask should be _____. (Dotted decimal format) slightly

255.255.254.0

NO.126 The two WAN interfaces S1/0 and S1/1 of the router MSR-1 are connected to the routers MSR-2 and MSR-3 respectively. At the same time, the Ethernet port of MSR-1 is connected to MSR-4, and all four routers run RIP protocol.
After the network 192.168.0.0 on MSR-1 fails, MSR-1 immediately sends the update message that the route is unreachable to the other three routers. If the suppression time is not considered, then ______. (Multiple choice)

RIP’s fast convergence mechanism is used on MSR-1

The trigger update mechanism of RIP is used on MSR-1

If MSR-1 has not had time to send the update information about this route, and it receives periodic route update information from neighboring routers, then the wrong routing information will be updated on MSR-1

This method of sending update messages immediately cannot completely avoid routing loops when used alone
