Question

Which of the following are true using multiple VLANS on a single switch? select two

A. The number of broadcast domains increases
B. The number of collision domains remain the same

Answer 1

Multiple VLANs on a single switch increase the number of broadcast domains, while the number of collision domains remains the same.

Step-by-step explanation:

When using multiple VLANs on a single switch, two things are true:

1. The number of broadcast domains increases.
2. The number of collision domains remains the same.

In a VLAN (Virtual LAN) environment, each VLAN can be considered as a separate broadcast domain, meaning that broadcast traffic is only sent to devices within the same VLAN. This can help to reduce network congestion and improve security.

However, the number of collision domains remains the same because collisions occur at the physical layer of the network, which is shared by all devices connected to the switch.
