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
Answer is F
Explanation.
192.216.32.32/29 means there are 6 usable host in the subnet
192.216.32.32 is the network address
192.216.32.39 is the broadcast address of the subnet
therefore, 33,34,35,36,37,38 are the usable host address in the subnet and the last usable host address is 38
prefix /29 means there are five bits taken from last octect for network portion 11111000 and therefore subnet mask should be 255.255.255.248
