Which of the following descriptions about the MSR routing table are correct? (multiple choice)

• A.If the same routing protocol finds multiple paths to the same destination network segment, then these routes may all be written into the routing table
• B.If the route to the same destination network segment has multiple sources, then only the route with the smallest Preference value will be written into the routing table
• C.If the route to the same destination network segment has multiple sources, then only the route with the highest Preference value will be written into the routing table
• D.If the route to the same destination network segment has multiple sources, only the route with the smallest metric value is written into the routing table
• E.If the route to the same destination network segment has multiple sources, then only the route with the largest metric value is written into the routing table
• F.If the same routing protocol finds multiple paths to the same destination network segment, then these routes cannot all be written into the routing table

The customer's network connection looks like:
HostA----GE0/0--MSR-1--S1/0---------S1/0--MSR-2--GE0/0----HostB
The network has been correctly configured with the IP address and routing. Currently, HostA and HostB can communicate with each other in the network.
For some security considerations, the customer requires that HostB cannot ping HostA, but at the same time HostA can ping HostB, and the transmission of other messages between HostA and HostB is not restricted, so which of the following statements is correct?

• A.This requirement can be achieved only by configuring ACL on MSR-2
• B.This requirement can be achieved only by configuring ACL on MSR-1
• C.Only configuring ACL on MSR-2 cannot achieve this requirement
• D.Only configuring ACL on MSR-1 cannot achieve this requirement
• E.When using the ping command, the ICMP packets between the two hosts are bidirectional, and this single intercommunication requirement cannot be realized

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. All four routers have run the RIP protocol and completed routing learning correctly. All routers have started all the features of RIP to prevent loops. At this time, it is found that the MSR -2 The network 192.168.0.0 fails, then ______ after a certain period of time. (Multiple choice)

• A.The 192.168.0.0 routing entries on all routers will enter the suppressed state
• B.If the network 192.168.0.0 returns to normal, MSR-2 will wait until the update cycle time point to send update information to other routers
• C.The cost of 192.168.0.0 routing items on all routers is set to the maximum value
• D.If the network 192.168.0.0 returns to normal, MSR-2 will immediately send routing update information
