Alibaba Cloud Certified Associate – Cloud Computing — Question 21

Which of the following ECS instance configurations can't be changed if we don't change instance type?

Answer options

• A. Mem size
• B. System disk size
• C. Data disk size
• D. Number of data disk

Correct answer: B

Explanation

The correct answer is B because the system disk size is fixed based on the instance type and cannot be altered without changing the instance type itself. The memory size, data disk size, and number of data disks can be adjusted independently of the instance type.
