Correct Answer: B,D,E
Explanation/Reference:
Explanation:
Well-known VLANs (for example: VLAN 1002 for fddi-default; VLAN 1003 for token-ring...) are configured by default -> A is not correct.
To communicate between two different VLANs we need to use a Layer 3 device like a router or Layer 3 switch -> B is correct.
VLANs don't affect the number of collision domains, they are the same. -> C is not correct.
Typically, VLANs increase the number of broadcast domains.We must use a different network (or sub- network) for each VLAN. For example we can use 192.168.1.0/24 for VLAN 1, 192.168.2.0/24 for VLAN 2 -
> D is correct.
A switch maintains a separate bridging table for each VLAN so, that it can send frames to ports on the same VLAN only. For example, if a PC in VLAN 2 sends a frame then the switch looks-up its bridging table and only sends frame out of its ports which belong to VLAN 2 (it also sends this frame on trunk ports) -> E is correct.
We can use multiple switches to expand VLAN -> F is not correct.
