Verification of System Design for Efficiency

D.

The correct answer is D. Load balancing between the servers has been implemented.

Explanation:

A cluster is a group of interconnected servers that work together to provide a single computing resource. The mission-critical application is deployed on the cluster to ensure high availability and reliability. In a cluster, load balancing is a technique used to distribute workloads across multiple servers to ensure optimal performance and efficiency. Load balancing helps to prevent server overload, reduce downtime, and provide better user experience.

The IS auditor should verify that load balancing has been implemented in the cluster to ensure optimal efficiency. The other options are not relevant to the question.

Option A is not relevant to the question because the security features in the operating system are not directly related to the performance and efficiency of the system.

Option B is not relevant to the question because the number of disks in the cluster is not directly related to the performance and efficiency of the system.

Option C is not relevant to the question because the two servers do not have to be of exactly the same configuration to ensure optimal efficiency.

Therefore, the correct answer is D. Load balancing between the servers has been implemented.
