The following routing information was found in the routing table of an MSR router:
Destination/Mask Proto Pre Cost NextHop Interface 2.0.0.0/8 XXX 100 48 10.10.10.2 S6/1
Then the correct description of this piece of routing information is ______. (Multiple choice)

• A.Proto in this route entry may be static
• B.Proto in this route item may be rip
• C.This path must be learned through dynamic routing
• D.This route must not be a direct route

The following statement about the functions of each layer of the OSI reference model is wrong.

• A.The session layer is responsible for data format processing, data encryption, etc.
• B.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.
• C.The basic function of the transport layer is to establish and maintain virtual circuits, perform error checking and flow control.
• D.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.
• E.The application layer is responsible for providing network services for applications.

An MSR router is connected to the Internet through the WAN interface, and the following interface display information is seen on the MSR router:
Mp-group1 current state: UP
Line protocol current state: UP
Description: Mp-group1 Interface
The Maximum Transmit Unit is 1500, Hold timer is 10(sec)
Internet Address is 172.16.1.100/24 ​​Primary
Link layer protocol is PPP
LCP opened, MP opened, IPCP opened
Physical is MP, baudrate: 64000 bps
Then the correct analysis of the information displayed above is _____. (Multiple choice question)

• A.The network layer protocol running on the interface is IP
• B.The interface Mp-group1 contains at least two physical interfaces
• C.The link layer protocol encapsulated by the interface is PPP
• D.The physical cable used by this interface is an MP cable

The following description about routing is correct ______. (Multiple choice)

• A.The priority of the direct route cannot be modified manually
• B.Route convergence means that the routes of the routers in the entire network are consistent
• C.IGP is a routing protocol based on D-V algorithm
• D.A complete route must include at least mask, destination address, and next hop

Run OSPF between the four MSR routers and divide the area. The connection and division methods are shown in the figure.

It is known that the OSPF Cost value of all links in the network is 10, so the correct description of this figure is ______. (Multiple choice)

• A.There are two equivalent paths for RTA to access RTC, namely RTA->RTB->RTC and RTA->RTD-RTC
• B.After the link between Area 0 fails, the path for RTA to access RTB is RTA->RTD->RTC->RTB
• C.All four routers in the network are ABR (Area Border Router)
• D.RTD access to RTB will give priority to RTD->RTA->RTB path
