Sample AWS Certification Cloud Practitioner 2025 questions

1. A small company wants to launch a new customer portal without purchasing servers in advance. Which cloud benefit most directly lets it replace large upfront infrastructure costs with usage-based costs?
  1. Increased fault tolerance
  2. Pay-as-you-go pricing
  3. Automatic compliance with every regulation
  4. Dedicated physical hardware for every workload

Answer: B. Pay-as-you-go pricing

Pay-as-you-go lets the company pay for cloud resources as it consumes them instead of buying infrastructure upfront. Cloud adoption does not automatically ensure regulatory compliance, so C is not a valid cost benefit.

2. An online retailer sees sharp, predictable traffic increases during monthly promotions. It wants its Amazon EC2 capacity to grow and shrink with demand while avoiding manual resizing. Which approach best meets this need?
  1. Purchase enough On-Demand instances to handle the largest possible traffic permanently
  2. Move the application to one larger EC2 instance and resize it manually each month
  3. Store application logs in Amazon S3
  4. Use an EC2 Auto Scaling group with scaling policies

Answer: D. Use an EC2 Auto Scaling group with scaling policies

An Auto Scaling group can add or remove instances as demand changes, matching capacity to workload and reducing manual operations. Keeping peak capacity running all month, as in A, wastes resources during quieter periods.

3. A media company serves the same public images to viewers around the world. It wants lower latency and less load on its origin server with minimal application changes. Which AWS service is the best fit?
  1. Amazon CloudFront
  2. AWS Direct Connect
  3. Amazon Inspector
  4. AWS Database Migration Service

Answer: A. Amazon CloudFront

CloudFront caches and delivers content through edge locations closer to viewers, reducing latency and origin requests. Direct Connect provides private network connectivity, not global content caching.

4. A company is designing a web service in one AWS Region and wants to reduce the risk that a single data-center-level failure will make the service unavailable. Which design choice best addresses this goal?
  1. Place all instances in one Availability Zone and create more backups there
  2. Use a different IAM policy for each instance
  3. Deploy the application across multiple Availability Zones
  4. Move all application files to one EC2 instance with a larger volume

Answer: C. Deploy the application across multiple Availability Zones

Deploying across multiple Availability Zones provides resilience to the failure of one zone within a Region. Backups in the same single zone, as in A, do not provide equivalent availability during a zone outage.

5. A developer needs read-only access to objects in one Amazon S3 bucket and no access to other buckets. Which IAM approach follows least privilege most closely?
  1. Attach AdministratorAccess to the developer's IAM user
  2. Share the AWS account root user credentials
  3. Grant only the required S3 read actions on the specified bucket and its objects
  4. Grant full S3 access to every user in the account

Answer: C. Grant only the required S3 read actions on the specified bucket and its objects

A narrowly scoped policy grants only the required read actions on the specified resources, following least privilege. AdministratorAccess, as in A, grants far more authority than the task requires.
