Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 223

A customer is planning to replace older access points with Cisco 4800 Series Access Points. Unaware of the infrastructure requirements, the client has an engineer investigate the inline power requirement. Which IEEE 802.3 standard complies with the Cisco 4800 Series Access Points?

Answer options

• A. 802.3bt
• B. 802.3at
• C. 802.3af
• D. 802.3ac

Correct answer: A

Explanation

The correct answer is A, 802.3bt, which supports higher power levels required by the Cisco 4800 Series Access Points. Options B and C, 802.3at and 802.3af, provide lower power levels and are therefore inadequate for the needs of the 4800 Series. Option D, 802.3ac, is not a standard that pertains to power over Ethernet and does not apply to this scenario.
