HostA cannot ping HostB. Assuming routing is properly configured, what is the cause of this
problem?
A.
HostA is not on the same subnet as its default gateway.
B.
The address of SwitchA is a subnet address.
C.
The Fa0/0 interface on RouterA is on a subnet that can’t be used.
D.
The serial interfaces of the routers are not on the same subnet.
E.
The Fa0/0 interface on RouterB is using a broadcast address.
Explanation:
Now let’s find out the range of the networks on serial link:
For the network 192.168.1.62/27:
Increment: 32
Network address: 192.168.1.32
Broadcast address: 192.168.1.63
For the network 192.168.1.65/27:
Increment: 32
Network address: 192.168.1.64
Broadcast address: 192.168.1.95
-> These two IP addresses don’t belong to the same network and they can’t see each other
