Q1. Which of the following AWS services are compute services? (Select TWO.)
Answer: B,D. AWS Batch || AWS Elastic Beanstalk
AWS Batch and AWS Elastic Beanstalk are both compute services: Batch runs batch computing jobs, and Elastic Beanstalk deploys and scales web applications. CloudTrail is for auditing, Inspector for security assessment, and EFS is file storage, so none of those count as compute.
Q2. Which task can a user complete using the AWS Cost Management tools?
Answer: B. Create budgets and receive notifications if current or forecasted usage exceeds the budgets.
AWS Budgets, part of the AWS Cost Management tools, lets you create budgets and get alerts when actual or forecasted usage exceeds them. Moving S3 data to another storage class is done with S3 lifecycle policies, not cost management tools.
Q3. A Cloud Practitioner needs to monitor a new Amazon EC2 instance's CPU and network utilization. Which AWS service should be used?
Answer: D. Amazon CloudWatch
Amazon CloudWatch collects performance metrics like CPU and network utilization for EC2 instances and lets you set alarms. CloudTrail records API calls for auditing, so think metrics versus audit logs when choosing between these two.
Q4. A user is planning to launch three EC2 instances behind a single Elastic Load Balancer. The deployment should be highly available. How should the user achieve this?
Answer: D. Launch the instances across multiple Availability Zones in a single AWS Region.
Spreading instances across multiple Availability Zones in one Region behind a load balancer provides high availability. A load balancer cannot span multiple Regions, and Spot versus Reserved pricing has no effect on availability.
Q5. What can a Cloud Practitioner use to categorize and track AWS costs by project?
Answer: C. Cost Allocation Tags
Cost allocation tags label resources by project or department so costs show up grouped in Cost Explorer and the cost allocation report. Consolidated billing only aggregates spending across accounts, not per project.
Q6. A company is deploying a MySQL database on AWS. The database must easily scale and have automatic backup enabled. Which AWS service should the company use?
Answer: D. Amazon Aurora
Amazon Aurora is MySQL-compatible, scales storage automatically up to large capacities, and includes automated backups. DynamoDB and DocumentDB are NoSQL databases, so they cannot host a MySQL database.
Q7. How does the AWS cloud increase the speed and agility of execution for customers? (Select TWO.)
Answer: A,D. Fast provisioning of resources || Scalable compute capacity
Fast provisioning and scalable compute capacity are core cloud advantages that deliver speed and agility. Lower cost is real but relates to cost optimization, not agility, so it's the strongest distractor here.
Q8. Which AWS services can a company use to gather information about activity in their AWS account? (Select TWO.)
Answer: C,E. Amazon CloudWatch || AWS CloudTrail
CloudTrail records account API activity and CloudWatch collects operational and billing metrics, so both reveal account activity. Trusted Advisor gives best-practice recommendations but does not log activity, which makes it the common wrong pick.
Q9. A company is designing a new service that must align with the operational excellence pillar of the AWS Well-Architected Framework. Which design principles should the company follow? (Select TWO.)
Answer: A,B. Anticipate failure. || Perform operations as code.
Anticipating failure and performing operations as code are both explicit operational excellence design principles. Manual operations and static procedures are the opposite of that pillar's guidance.
Q10. What are AWS Identity and Access Management (IAM) access keys used for?
Answer: B. Making programmatic calls to AWS from AWS APIs.
IAM access keys authenticate programmatic requests to AWS APIs, the CLI, and SDKs. Console sign-in uses a user name and password, which is the most tempting wrong option.
Q11. A media company wants to find and subscribe to third-party data sources to enrich their existing datasets with new insights. Which AWS service would be the best fit for this requirement?
Answer: D. AWS Data Exchange
AWS Data Exchange lets customers find, subscribe to, and use third-party data products in the cloud. Glue and Data Pipeline move and transform data but do not provide a marketplace for subscribing to external datasets.
