CCNA: Cisco Certified Network Associate — Question 1256

What prevents a workstation from receiving a DHCP address?

Answer options

• A. STP
• B. VTP
• C. 802.1Q
• D. DTP

Correct answer: A

Explanation

The correct answer is A, STP (Spanning Tree Protocol), which can block network ports to prevent loops, potentially stopping a workstation from receiving a DHCP address. The other options, VTP (VLAN Trunking Protocol), 802.1Q (VLAN tagging), and DTP (Dynamic Trunking Protocol), do not directly influence the DHCP process and are related to VLAN management and trunking rather than the DHCP lease acquisition.
