Data segmentation is done in ______ in the OSI reference model.

The common fields of UDP protocol and TCP protocol header are ______. (Multiple choice)

The IP address 10.0.10.65 and the mask 255.255.255.224 represent a ______.

The customer's network connection looks like:
HostA----GE0/0--MSR-1--S1/0-----WAN----S1/0--MSR-2--GE0/0----HostB
The two MSR routers are interconnected through the WAN, and the physical connection is now normal. The address of interface S1/0 of MSR-1 is 3.3.3.1/30, and the address of interface S1/0 of MSR-2 is 3.3.3.2/30. Now the following 4 static routes are configured on MSR-1:
ip route-static 192.168.1.0 255.255.255.0 3.3.3.2
ip route-static 192.168.2.0 255.255.255.0 3.3.3.2
ip route-static 192.168.3.0 255.255.255.0 3.3.3.2
ip route-static 192.168.4.0 255.255.255.0 3.3.3.2
The 192.168.0.0/22 ​​subnet is the LAN user network segment of MSR-2.
So which of the following descriptions are wrong? (multiple choice)

Different priority levels can be configured for Telnet users on the MSR router. What is wrong about this priority level is ______. (Multiple choice)
