Can anyone help to answer the following questions?
1.Which wireless data command type has a high data rate but is limited to very short distances?
B. spread spectrum
D. broadband personal comm. Service (PCS)
2.Which protocol admin overhead in a switch network by allowing the configuring of a new VLAN to be distributed to all the switches in a domain?
While I'm not certain about the first question, the answer to the second question is B.
VTP Stands for Virtual Trunck Protocol and is used amongst switches that support VLANs. The VTP protocol allows the switches to update their database and be aware of any new VLANS that have been created.
The VTP protocol is a whole study its self and we will be covering it in the near future.
