VMware vSphere 6 Beta — Question 46

An application requires load balancing with minimal impact to network performance. An NSX administrator is deploying a load balancer to meet the stated requirements.
Which load balancing engine should be deployed?

Answer options

• A. Layer 5
• B. Layer 6
• C. Layer 7
• D. Layer 4

Correct answer: D

Explanation

Layer 4 load balancing operates at the transport layer and is less resource-intensive, thus minimizing the impact on network performance. In contrast, Layer 5 and Layer 6 are less common and typically not used for load balancing, while Layer 7, which operates at the application layer, can introduce higher latency due to additional processing of application data.
