An engineer is determining powering requirements for a P2P wireless link using Cisco Aironet 1572EC access points.
Which power method is valid for the access point?
A. 802.3af Power over Ethernet
B. Power over Cable
C. Cisco Inline Power
D. 802.3at Power over Ethernet
Answer is B
The 1572EC letter variants at the end of the model number: “E” = External Antenna, “C” = Power over Cable

Correct
B and D seem valid.
From data sheet: Power: AC, DC, Cable, UPOE, PoE-Out (802.3at)
Could be D, since this AP uses PoE+ (802.3at)
