Which of the following is a cost efficiency principle related to the AWS Cloud?
Right size services based on capacity requirements
Use the Billing Dashboard to access information about monthly bills
Use AWS Organizations to combine the expenses of multiple accounts into a single bill
Tag all AWS resources
Explanations:
Right sizing services based on capacity requirements helps optimize resource usage and reduces costs by ensuring you only pay for the resources you actually need.
While using the Billing Dashboard is useful for tracking expenses, it does not directly relate to cost efficiency in managing resources or minimizing costs.
Using AWS Organizations to combine expenses is more about billing management than cost efficiency; it does not inherently reduce costs.
Tagging resources is important for organization and management, but it does not directly lead to cost efficiency unless it is specifically used for tracking and optimizing spending.
From my perspective, the answer is:
Right size services based on capacity requirements
