CCNA: Cisco Certified Network Associate — Question 178

Which two pieces of information about a Cisco device can Cisco Discovery Protocol communicate? (Choose two.)

Answer options

• A. the native VLAN
• B. the trunking protocol
• C. the VTP domain
• D. the spanning-tree priority
• E. the spanning-tree protocol

Correct answer: A, C

Explanation

The correct answers are A and C because Cisco Discovery Protocol can convey information about the native VLAN and the VTP domain of a Cisco device. The other options, while related to networking, are not communicated by CDP, as it does not provide details on the trunking protocol, spanning-tree priority, or spanning-tree protocol.
