Explanation:

Analyze CDP capabilities

Using the Cisco Discovery Protocol and CDP Functionality knowledge points

• CDP is a proprietary Layer 2 protocol used to share information between directly connected Cisco devices.
• It advertises device identifiers (hostnames), software/IOS versions, hardware platforms, capabilities, active interfaces, and Power over Ethernet (PoE) requirements.
• It does not share dynamic table data, such as the size or contents of the MAC address table.

Evaluate the given options

Using the CDP Functionality knowledge point

• A. MAC address table sizes: This is dynamic database information and is not reported by CDP.
• B. IOS version: This is standard system software information reported by CDP.
• C. Power over Ethernet usage: This is reported via CDP power-negotiation TLVs.
• D. Device ID/hostname: This is a fundamental identifier reported by CDP.

Answer:

• (A) MAC address table sizes (Correct answer)
• (B) IOS version
• (C) Power over Ethernet usage
• (D) Device ID/hostname
