CompTIA Network+ (N10-008) — Question 319

An administrator wants to increase the availability of a server that is connected to the office network. Which of the following allows for multiple NICs to share a single IP address and offers maximum performance while providing fault tolerance in the event of a NIC failure?

Answer options

• A. Multipathing
• B. Spanning Tree Protocol
• C. First Hop Redundancy Protocol
• D. Elasticity

Correct answer: A

Explanation

Multipathing allows multiple NICs to work together with a single IP address, ensuring that if one NIC fails, the others can continue to provide network access, thereby maximizing performance and availability. The Spanning Tree Protocol is designed to prevent loops in network topologies, while First Hop Redundancy Protocol focuses on redundancy for the first hop in the routing process. Elasticity refers to the ability to dynamically allocate resources and is not related to NICs or IP address sharing.
