Which is a SKU for Mobility Express?

Question

Options

• AAIR-AP1815W-X-K9
• BAlR-AP28021-K9
• CAIR-AP18151-K9C
• DAlR-AP18521-K9

• A
  5% (1)
• C
  95% (21)

Explanation

Option C (AIR-AP18151-K9C) is correct because the trailing "C" in the SKU suffix -K9C specifically designates a Cisco Mobility Express bundle - the "C" stands for Controller, indicating the AP includes embedded Mobility Express wireless controller software, enabling it to manage other APs without a dedicated physical controller.

Why the distractors are wrong:

• A (AIR-AP1815W-X-K9): The W indicates a wall-plate form factor AP; it ends in -K9 with no "C," so it carries no Mobility Express designation.
• B (AIR-AP28021-K9): This is a 2802-series AP ending in plain -K9 - no embedded controller capability indicated.
• D (AIR-AP18521-K9): Similarly, the 1852-series AP here also ends in -K9, not -K9C, so it is a standard AP SKU.

Memory tip: Look for the "C" at the end of the SKU (-K9C vs -K9). Think: C = Controller. If the SKU doesn't end with that extra "C," it's just a regular AP - no Mobility Express included.
