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?
Correct Answer: D
LACP (Link Aggregation Control Protocol) can be used to increase bandwidth to a server without replacing hardware. LACP allows multiple network connections to be bundled together to increase throughput and provide redundancy. This is also known as link aggregation or NIC teaming. By using LACP, the IT technician can combine multiple gigabit ports on the server to create a single high-bandwidth connection without replacing any hardware. STP (Spanning Tree Protocol), 802.1Q (VLAN tagging), and duplex settings do not increase bandwidth but rather control network topology, network segmentation, and communication speed, respectively.
