A company wants to ensure high availability and maximum throughput while building a new server cluster. What does a teamed interface refer to?

1. Link aggregation

2. Elasticity on demand

3. A TCP offload engine

4. Resource pooling

The correct answer is: Link aggregation

A teamed interface refers to link aggregation, which is a technique used to combine multiple network interfaces into a single logical interface. This method enhances network performance and provides redundancy, which is essential for achieving high availability and maximum throughput in a server cluster. When using link aggregation, data can be transmitted across multiple network paths simultaneously, which increases the overall bandwidth available to the servers. This distribution of traffic helps prevent bottlenecks and ensures that the network can handle higher loads efficiently. Additionally, if one of the network interfaces fails, the remaining interfaces can continue to function, maintaining network connectivity and improving the system's reliability. The other options do not specifically pertain to the concept of a teamed interface: - Elasticity on demand relates to the ability to adjust resources dynamically based on workload requirements, which is a broader cloud computing concept rather than a specific technique for enhancing network capacity. - A TCP offload engine refers to hardware that takes over some of the processing tasks related to TCP/IP network protocols, but it is not directly related to combining multiple interfaces or improving throughput through aggregation. - Resource pooling describes a cloud computing service model where resources are shared dynamically among various users but, again, does not connect directly to the concept of teaming network interfaces to optimize network performance.
