What happens during wireless roaming?

• A. Client moves between access points during activity to minimize latency
• B. Router firmware gets updated automatically
• C. Roaming increases encryption overhead but not latency
• D. Access point channels are changed dynamically by client

Answer: (A)

Wireless roaming is about a client moving between different access points within the same network while staying connected, so ongoing activity continues with minimal interruption. As the device detects that the signal from one AP is weakening or quality is dropping, it searches for and connects to a better AP along the same network. The handoff is designed to be fast, often using techniques like pre-authentication and fast transitions to keep latency low and prevent dropped connections.

The other options don’t fit roaming: having a router update its firmware automatically is a network management action, not a client handoff; roaming isn’t defined by encryption overhead or latency changes in that sense—any re-authentication during a transition is minimized to keep performance stable; and the client doesn’t dynamically change AP channels—the network components control AP channels, while roaming involves moving from one AP to another.
