Cisco inline power was replaced by which IEEE standard?

Answer options

• A. 802.3at
• B. 802.3af
• C. 802.11n
• D. 802.11ac

Correct answer: B

Explanation

The correct answer is B, 802.3af, which defines Power over Ethernet (PoE) standards that replaced Cisco's inline power. Option A, 802.3at, is an enhancement of 802.3af, but it did not replace it. Options C and D, 802.11n and 802.11ac, are wireless standards and are not related to inline power.
