Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 228

A technician connects a Cisco Aironet 3700 Series AP to a switch and realizes that the AP is coming up with 3x3 MIMO. What explains this behavior?

Answer options

• A. A redundant power supply is unavailable on the switch.
• B. The switch is 802.3af capable.
• C. The AP is getting power from a power injector.
• D. The switch is PoE+ capable.

Correct answer: B

Explanation

The correct answer is B because the Cisco Aironet 3700 Series AP requires 802.3af power to operate in 3x3 MIMO mode. If the switch were not 802.3af capable, it would not provide sufficient power for this functionality. Options A, C, and D do not apply because they either refer to different power supply configurations or suggest a capability that is not relevant to the AP's operation mode.
