CompTIA Network+ (N10-008) — Question 390

An IT technician needs to increase bandwidth to a server. The server has multiple gigabit ports. Which of the following can be used to accomplish this without replacing hardware?

Answer options

• A. STP
• B. 802.1Q
• C. Duplex
• D. LACP

Correct answer: D

Explanation

The correct answer is D, LACP, which stands for Link Aggregation Control Protocol and allows multiple network interfaces to be combined for greater bandwidth. The other options do not serve the purpose of aggregating bandwidth; STP (Spanning Tree Protocol) is for preventing loops, 802.1Q is for VLAN tagging, and Duplex refers to the communication mode, not bandwidth aggregation.
