Which command would correctly configure a serial port on a router with the last usable host address in the 192.216.32.32/29 subnet?
A. router (config-if)# ip address 192.216.32.38 255.255.255.240
B. router (config-if)# ip address 192.216.32.39 255.255.255.224
C. router (config-if)# ip address 192.216.32.63 255.255.255.248
D. router (config-if)# ip address 192.216.32.39 255.255.255.248
E. router (config-if)# ip address 192.216.32.63 255.255.255.248
F. router (config-if)# ip address 192.216.32.38 255.255.255.248
Correct Command for Serial Port Configuration:
The correct command to configure a serial port with the last usable host address in the 192.216.32.32/29 subnet is 'router (config-if)# ip address 192.216.32.38 255.255.255.248' (option F).
Networking is a crucial skill in today's interconnected world, and troubleshooting scenarios like this one can help you sharpen your abilities. By understanding subnetting and configuration commands, you can confidently navigate various networking challenges.
In this case, the /29 subnet mask results in a block size of 8 IP addresses, ranging from 192.216.32.32 to 192.216.32.39. The first IP address is the network address, and the last IP address is the broadcast address. Hence, the last usable host address is one less than the broadcast address, which is 192.216.32.38. The corresponding subnet mask 255.255.255.248 signifies a /29 prefix length.
Remember, practice makes perfect in the world of networking! Keep challenging yourself with troubleshooting scenarios like this one to enhance your skills and knowledge.
