Correct answers: A, B, D
Explanation
When performing database capacity and usage planning, it is essential to analyze variables such as storage growth, peak usage patterns, and performance requirements. These factors ensure that the database is adequately provisioned to handle current and future workloads efficiently. While migration-specific details like software compatibility or physical server locations may be important, they do not directly impact capacity and usage planning.
- A. Correct.
Correct: Understanding the growth rate of storage requirements ensures the database can scale effectively in the cloud and avoids performance bottlenecks.
- B. Correct.
Correct: The number of simultaneous users during peak hours is crucial for determining the database's capacity needs and ensuring it can handle peak load without degradation.
- C. Incorrect.
Incorrect: While software version compatibility may be important for migration planning, it is not directly related to capacity and usage planning.
- D. Correct.
Correct: Query performance requirements are critical to ensure the database is provisioned with sufficient resources to meet expected SLAs.
- E. Incorrect.
Incorrect: The physical location of on-premises servers is not directly relevant to analyzing capacity and usage planning when migrating to the cloud.
