With which options can you use a single SSID/VLAN configuration for a WLAN?

Question

Options

• Acontinuously changing wireless clients
• Bmultiple wired automation devices
• Ca fixed set of wireless clients using the 5 GHz radio
• Da fixed set of wired automation devices

• A
  7% (4)
• B
  2% (1)
• C
  87% (48)
• D
  4% (2)

Explanation

A single SSID/VLAN configuration suits a fixed set of wireless clients on 5 GHz because the client population is stable and predictable - you know exactly which devices will connect, so there's no need for multiple VLANs to segment or enforce different policies across device types. Options B and D are wrong because wired automation devices don't use SSIDs at all - SSIDs are wireless identifiers assigned to access points, and wired devices connect via switch ports, making SSID/VLAN pairing irrelevant to them. Option A is wrong because continuously changing clients introduce unknown or diverse devices that typically require multiple SSIDs/VLANs to enforce proper segmentation, QoS, or security policies per device group.

Memory tip: Think "Single SSID = Single, stable, same-type wireless group." If the client set is fluid or the devices aren't even wireless, a single SSID/VLAN breaks down fast.
