CompTIA Network+ (N10-007) — Question 215

A network technician is connecting two switches together. Which of the following protocols should the technician use to increase speed and fault tolerance?

Answer options

• A. SIP
• B. BGP
• C. LACP
• D. LLDP

Correct answer: C

Explanation

The correct answer is LACP (Link Aggregation Control Protocol), which allows multiple physical links to be combined into a single logical link, increasing throughput and providing redundancy. SIP and BGP are not used for switch interconnections, and LLDP is for network device discovery rather than link aggregation.
