When two computers communicate with each other, they send information back and forth. If they are separated by a reasonable distance, they can send and receive the information through a direct cable connection which is called a null-modem connection. Presently what is the maximum distance in metres permitted in this null-modem connection?

Which of the following is true regarding VLANs?

VTP is used to send VLAN information to switches in a configured VTP domain.

All VLANs are configured at the fastest switch and, by default, propagate this information to all other switches.

You should not have more than 10 switches in the same VTP domain.

You must have at least two VLANs defined in every Cisco switched network.
