Regarding the method of AP access control below, which of the following statement is incorrect? (Multiple choice)

Question

Options

• ABy default, the control method for AP access to AC is non-authentication
• BBy configuring the AP in an offline state, authentication is required before automatic access
• CConfiguration whitelist can be authenticated based on MAC or SN
• DIf MAC authentication is used for AP access control, APs outside the MAC authentication list can

• A
  72% (21)
• C
  10% (3)
• D
  17% (5)

Explanation

Options A and B are the incorrect statements because they misrepresent the default behavior and the role of offline status in AP access control.

A is wrong because the default AP access control method is not "non-authentication" - the system actually requires authentication (typically MAC or SN whitelist verification) before an AP is permitted to join the AC automatically. Open, non-authenticated access is not the out-of-the-box default.

B is wrong because placing an AP in an offline state does not impose or change authentication requirements. Offline configuration and authentication mode are independent settings; you cannot use offline state as a mechanism to force authentication before automatic access.

C is correct - whitelist authentication legitimately supports both MAC address and Serial Number (SN) as valid identification criteria, so this statement accurately reflects system capability.

D is correct - it accurately describes the behavior for APs that fall outside the MAC authentication whitelist (they are denied automatic access), which is the expected and intended behavior of MAC-based access control.

Memory tip: Think "ODAM" - Offline ≠ Auth trigger, Default ≠ No-auth, MAC/SN whitelists work, and outsiders are blocked. Any option that conflates offline state with authentication logic, or claims the default is open access, is a trap.
