The correct answer is C. The deployment was successful, but the capacity planning was inaccurate. The database is slow despite a successful deployment, indicating that the initial capacity planning did not accurately predict the system's actual resource requirements.

Question

Joe, a systems administrator, deployed a computer and storage for a system and took it to the application team. The next day, the application team claimed the database was slow. The deployment request, result, and current utilization data are shown below. Which of the following descriptions of the situation is correct?

Options

  • AThe deployment was done with the wrong memory configuration.
  • BThe deployment was unsuccessful due to the cloud failure.
  • CThe deployment was successful, but the capacity planning was inaccurate.
  • DThe deployment was done with the wrong storage parameter.

Why each option

The database is slow despite a successful deployment, indicating that the initial capacity planning did not accurately predict the system's actual resource requirements.

AThe deployment was done with the wrong memory configuration.

If the deployment met the requested memory configuration, and it was still slow, it suggests the requested memory was insufficient, not that the deployment had the wrong configuration from the request.

BThe deployment was unsuccessful due to the cloud failure.

There is no information provided to suggest a cloud failure; the problem is described as a slow database after a deployment, which implies the deployed resources are insufficient, not that the cloud infrastructure failed.

CThe deployment was successful, but the capacity planning was inaccurate.Correct

If the deployment was successful, meaning the requested resources were allocated, but the database is still slow, it implies that the initial assessment of resource needs was insufficient. This scenario points to inaccurate capacity planning, where the requested CPU, memory, or storage I/O might have been too low for the actual workload, leading to performance bottlenecks when the application began active use. The administrator fulfilled the request, but the request itself was inadequate for the application's demands.

DThe deployment was done with the wrong storage parameter.

Similar to memory, if the storage was deployed according to specification but the database is slow, it indicates the storage parameters requested during planning were insufficient, not that the deployment itself was done with the wrong parameters.
