Tenants access multiple wireless networks in a building. Users report intermittent connectivity. Which of the following is the MOST likely cause of the problem?

Question

Options

• AThe channels are overlapping with other wireless networks and should be changed.
• BThe SSIDs are incompatible and should be renamed.
• CThe users have incompatible wireless network cards and should upgrade.
• DThe default idle period for logoff is too short and should be changed to a longer limit.

• A
  84% (31)
• B
  11% (4)
• C
  3% (1)
• D
  3% (1)

Explanation

In a building with multiple wireless networks (from different tenants or organizations), overlapping Wi-Fi channels cause radio frequency (RF) interference. In the 2.4 GHz band, only channels 1, 6, and 11 are non-overlapping; if neighboring networks use adjacent channels (e.g., 1, 2, 3), their signals interfere and cause intermittent drops. The fix is to configure each network to use non-overlapping channels. SSID naming has no effect on connectivity. Network cards rarely cause building-wide intermittent issues across multiple users. The idle timeout logoff setting is a session management feature unrelated to RF interference.
