Question
Which AWS service is always available free of charge to users?
Options
- AAmazon Athena
- BAWS Identity and Access Management (IAM)
- CAWS Secrets Manager
- DAmazon ElastiCache
Explanation
AWS IAM is always free - it's a foundational identity service that AWS provides at no cost because controlling access to your AWS account is considered a prerequisite to using any other service. You are never charged for creating users, groups, roles, or policies.
Why the distractors are wrong:
- Amazon Athena (A) charges per query based on the amount of data scanned.
- AWS Secrets Manager (C) charges per secret stored per month, plus per 10,000 API calls.
- Amazon ElastiCache (D) charges for node hours based on instance type and size.
Memory tip: Think of IAM as the "front door lock" - AWS gives you the lock for free because you must have it to safely use anything else. Services that store data, run queries, or spin up infrastructure always cost money; services that just control access to those resources do not.
