Explanation
Host A address fall within the address range. However, if more than one route to the same subnet exist (router will use the longest stick match, which match more specific route to the subnet). If there are route
10.10.13.192/26 and 10.10.13.208/29, the router will forward the packet to /29 rather than /28.

Explanation:
The "show ip ospf database" command displays the link states. Here is an example:
Here is the lsa database on R2.

Section: Network Access
Explanation:
Although CDP is a Layer 2 protocol but we can check the neighbor IP address with the "show cdp neighbor detail" command. If the neighbor does not has an IP address then CDP still operates without any problem. But the IP address of that neighbor is not provided.

Explanation
From the neighbor status, we notice the "Flags" are SP. "P" here means the neighbor is in Passive mode.In order to create an Etherchannel interface, the (local) SW1 ports should be in Active mode.Moreover, the "Port State" in the exhibit is "0x3c" (which equals to "00111100 in binary format).Bit 3 is "1" which means the ports are synchronizing -> the ports are working so the local ports should be in Active mode.
