Q20. What is true about static VLANs? [Choose the best answer]. A. The VLAN is configured by a TFTP server. B. It automatically notify a new network user. C. The administrator assigns VLAN by port. D. Static VLAN are more appropriate when the switch fabric becomes more complex.
|
Correct answer: C
Explanation:
Static VLANs: The administrator statically configures VLAN port assignment. VLAN memberships on the switch ports are assigned on a port-by-port basis.
Dynamic VLANs: A VMPS (VLAN Management Policy Server) can dynamically assign VLAN ports. The MAC address of the node is used to determine the VLAN assignment. A separate server or a Catalyst 5000 can function as a VMPS server. When a frame arrives on a dynamic port at the switch, it queries the VMPS for the VLAN assignment based on the source MAC address of the arriving frame.
