Show answer and explanation
Correct answers: A, B
Explanation
Reserved Instances provide cost savings and some flexibility by allowing modifications to certain attributes such as the Availability Zone and instance type within the same instance family. However, some attributes, like operating system, term length, and payment option, are fixed and cannot be modified once a Reserved Instance is purchased. Understanding these capabilities helps organizations make informed decisions when planning their capacity and cost optimization strategies.
- A. Correct.
This is correct. You can modify the Availability Zone of a Reserved Instance within the same region to provide flexibility.
- B. Correct.
This is correct. Reserved Instances allow you to change the instance type within the same instance family (e.g., from t3.medium to t3.large), providing flexibility for changing workloads.
- C. Incorrect.
This is incorrect. The operating system cannot be changed for a Reserved Instance once it is purchased.
- D. Incorrect.
This is incorrect. The term length of a Reserved Instance (e.g., 1 year or 3 years) is fixed and cannot be modified after purchase.
- E. Incorrect.
This is incorrect. The payment option (e.g., All Upfront, Partial Upfront, No Upfront) is also fixed at the time of purchase and cannot be changed later.
