Q55. According to the definition of the OSI seven-layer reference model, _____ is responsible for providing flow control, checking the correctness of data transmission, and providing support for multiple upper-layer protocols. (Multiple choice)

Application layer

Data link layer

Presentation layer

Transport layer

Network interface layer

Physical layer

Session layer

Network layer

Q56. A network environment looks like:
HostA—-GE0/0–MSR-1–S1/0—–Frame Relay—-S1/0–MSR-2–GE0/0—-HostB
Among them, two routers MSR-1 and MSR-2 connect to the frame relay network through S1/0 respectively. Configure IP addresses 3.3.3.1/24 and DLCI 31 on the S1/0 interface of MSR-1, and configure IP addresses 3.3.3.2/24 and DLCI 82 on the S1/0 interface of MSR-2. The physical connection is completely normal, and the other default configurations are the same.
So which of the following statements are wrong? (multiple choice)

On a frame relay network, DLCI 31 can identify MSR-1, and DLCI 82 can identify MSR-2.

On a frame relay network, the corresponding relationship between DLCI 31 connected to MSR-1 and DLCI 82 connected to MSR-2 must be correctly configured, so that the S1/0 interfaces of the two routers can communicate with each other.

In the frame relay network exchange process, the source DLCI is always 31, and the destination DLCI will change. Until the last hop, the destination DLCI becomes 82.

After configuring the command ip address negotiate on the S1/0 interface of MSR-1, it can dynamically obtain the address from MSR-2.

Q57. The interface information of a router is displayed as follows:

Interface is DCE, Cable type is V35, Clock mode is DCECLK
What kind of protocol may be encapsulated or run on this interface?

PPP

HDLC

Frame Relay

RIP

None of the above answers are correct

Batch file

text file

executable file

database file

Q59. The correct statement about the OSI reference model is ______.

The data of the transport layer is called a frame (Frame)

The data of the network layer is called segment (Segment)

The data at the data link layer is called a packet (Packet)

The data of the physical layer is called bit (Bit)

Q60. Customers need to configure two static routes to the same destination address on the router to achieve the purpose of mutual backup.
Then the correct statement about the configuration of these two routes is ______.

Need to configure different Preferences for the two routes

Need to configure different Priority for the two routes

Need to configure different Costs for the two routes

Need to configure different MED for the two routes

Q61. As shown in the figure, the three MSR routers run OSPF and RIP respectively.

Now that the OSPF neighbor status between RTA and RTB is stable, and the RIPv2 between RTB and RTC is also working normally, then within 40 minutes from this moment, ______. (Multiple choice)

There must be a packet with a multicast address of 224.0.0.13 in the network

There must be a packet with a multicast address of 224.0.0.5 in the network

RTB has sent all its routing table information to RTC at least 10 times

RTB has sent its own LSA summary information to RTA at least once

Q62. 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)

save

Q63. 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

Q64. The following statements about OSPF information display and debugging commands are correct _____. (Multiple choice)

Use the display ospf peer command to view the router’s OSPF neighbor relationship

You can view the link state database of the router through the display ospf lsdb command. The link state database of all OSPF routers in the network should be the same

Use the display ospf routing command to view the router’s OSPF routing situation, not all OSPF routes will be added to the global routing table

View OSPF error information through display ospf fault

Q65. If a port running STP in the Ethernet switch does not receive or forward data, receive, process and send BPDUs, and perform address learning, the port should be in the ______ state.

Blocking

Listening

Learning

Forwarding

Waiting

Disable

Q66. Router MSR-1 is interconnected with MSR-2 and MSR-3 respectively. Among them, there is a RIP route learned from MSR-2 to the destination network segment 120.10.12.0/24 in the routing table of MSR-1. It is 3; at this time, MSR-1 also receives a RIP route from MSR-3 that is still going to the destination network segment 120.10.12.0/24, and its Cost is 15, then ______.

The routing table of MSR-1 is not updated, and the network segment route learned from MSR-2 is still retained

The routing table of MSR-1 will be updated to the route learned from MSR-3 to the cost of 15.

The routing table of MSR-1 will be updated, because RIP routing with a Cost of 15 means that the network may have loops

The routing table of MSR-1 will not be updated, because RIP routing with a Cost of 15 means unreliable routing, and RIP will not write it into its routing table

Q67. On the MSR router, use the ______ command to configure the NAT address pool.

nat address-group

nat ip pool

nat net pool

nat pool

Q68. After executing the display vlan 2 command on the switch SWA, the switch output is as follows:
<SWA> display vlan 2
VLAN ID: 2
VLAN Type: static
Route interface: not configured
Description: VLAN 0002
Tagged Ports: none
Untagged Ports:
Ethernet1/0/1 Ethernet1/0/3 Ethernet1/0/4
It can be judged from the above output ______. (Multiple choice)

Port Ethernet1/0/1 is a Trunk port hybrid

VLAN2 contains ports Ethernet1/0/1, Ethernet1/0/3 and Ethernet1/0/4

Data frames with VLAN2 tags need to be stripped off when they leave port Ethernet1/0/3

The current VLAN on the switch is only VLAN2 and Vlan1 must exist

Q69. 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
6.6.0/24 RIP 100 1 100.1.1.1 GE0/0
6.0.0.0/8 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 preferentially match the RIP route in the routing table because it has the longest mask

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

The packet will first match the static route in the routing table because its cost is low

The packet will preferentially match the static route in the routing table because its mask is the shortest
