Sample AWS SAA-C03 Practice Questions

Here are more practice questions to help you prepare for the exam:

1) A company wants to store logs for analysis. They want a solution that can scale with their growing log data, is cost-effective, and supports long-term retention. Which AWS service should they use?

• A. Amazon S3 
• B. Amazon RDS 
• C. Amazon DynamoDB 
• D. AWS CloudWatch Logs 

Answer: D. AWS CloudWatch Logs

Explanation:
AWS CloudWatch Logs is the best solution for logging and monitoring data. It scales easily as your data grows, and you only pay for the storage you use. CloudWatch Logs also integrates with other AWS services, enabling you to create alarms based on specific log patterns. S3 could be used for storing logs, but it lacks the real-time monitoring features that CloudWatch provides. RDS and DynamoDB are used for database management and are not suited for log storage.

2) A company has deployed a web application across two Availability Zones in a region. They want to improve the availability of the application. What should they do?

• A. Enable Multi-AZ for the database 
• B. Use Amazon CloudFront for content delivery 
• C. Add another Elastic Load Balancer in a third Availability Zone 
• D. Deploy the application in two additional regions 

Answer: A. Enable Multi-AZ for the database

Explanation:
To improve the availability of the application, enabling Multi-AZ for the database is the best solution. Multi-AZ deployments automatically provide high availability by creating a primary database in one Availability Zone and a synchronous standby replica in another. CloudFront speeds up content delivery, but it doesn’t address application availability directly. Adding another Elastic Load Balancer is unnecessary and will increase costs. Deploying in two additional regions might add unnecessary complexity without immediate benefits for availability.

3) A developer needs to deploy code changes automatically when a change is committed to a version control system. Which AWS service should they use?

• A. AWS CodeDeploy 
• B. AWS CloudFormation 
• C. AWS CodePipeline 
• D. AWS Elastic Beanstalk 

Answer: C. AWS CodePipeline

Explanation:
AWS CodePipeline automates the process of deploying applications by integrating with source control systems like GitHub or CodeCommit. It is specifically designed for continuous integration and continuous deployment (CI/CD) workflows. CodeDeploy is used for deployment, but doesn’t automate the full pipeline. CloudFormation is for infrastructure as code. Elastic Beanstalk is a platform-as-a-service solution for web apps, but it doesn’t handle the full automation of code changes.

4) A company wants to reduce its AWS costs by automatically moving data to a lower-cost storage class after it has not been accessed for a while. Which feature should they use?

• A. S3 Lifecycle Policies 
• B. S3 Versioning 
• C. S3 Transfer Acceleration 
• D. S3 Intelligent-Tiering 

Answer: A. S3 Lifecycle Policies

Explanation:
S3 Lifecycle Policies automate the process of transitioning data to different storage classes based on certain criteria, such as age or last access date. This is an effective way to reduce storage costs. S3 Versioning and Transfer Acceleration are unrelated to cost optimization, and S3 Intelligent-Tiering automatically moves data based on access patterns but doesn’t allow for explicit cost-based transitions.

5) Which of the following is the most appropriate way to monitor AWS resources and applications in real time?

• A. AWS CloudWatch 
• B. AWS Inspector 
• C. AWS Config 
• D. AWS X-Ray 

Answer: A. AWS CloudWatch

Explanation:
AWS CloudWatch provides real-time monitoring of AWS resources, services, and applications. It can track metrics, log data, and trigger alarms based on specific thresholds. AWS Inspector is used for security vulnerability assessments, AWS Config tracks configuration changes, and AWS X-Ray helps with debugging and analyzing microservices applications, but does not focus on general resource monitoring.

6) A company needs to store sensitive customer data in compliance with regulations. They need to ensure that the data is encrypted both in transit and at rest. Which of the following is the best solution?

• A. Enable server-side encryption for S3 
• B. Use VPC with a private subnet for data storage 
• C. Use IAM policies to control data access 
• D. Use AWS Key Management Service (KMS) for encryption 

Answer: D. Use AWS Key Management Service (KMS) for encryption

Explanation:
AWS KMS allows you to create and manage encryption keys for encrypting data both in transit and at rest. Enabling server-side encryption on S3 is a good practice, but KMS provides a more robust and integrated encryption solution. IAM policies help with access control, but they don’t directly address encryption. Using a VPC and a private subnet secures the data’s network environment, but doesn’t address encryption requirements.

• A. AWS Fargate 
• B. Amazon EC2 
• C. AWS Lambda 
• D. Amazon S3 

Answer: C. AWS Lambda

Explanation:
AWS Lambda is ideal for running code in response to events, and it scales automatically based on the number of events. It runs only when needed, which helps reduce costs for workloads that do not require continuous compute resources. EC2 and Fargate are better suited for running long-running applications. S3 is used for storage and not for compute purposes.

2) A company needs to ensure high availability for its database. The database should automatically failover to a secondary instance in the event of a failure. Which configuration should be used to meet this requirement?

• A. Multi-AZ deployment for RDS 
• B. Enable read replicas for RDS 
• C. Use Amazon S3 with versioning enabled 
• D. Deploy EC2 instances in multiple regions 

Answer: A. Multi-AZ deployment for RDS

Explanation:
A Multi-AZ deployment for RDS automatically provides high availability and failover capabilities. It replicates data to a standby instance in another Availability Zone, allowing for automatic failover in the event of a failure. Read replicas are useful for scaling read operations, but they do not provide automatic failover. S3 versioning and EC2 instances in multiple regions do not provide database failover capabilities.

3) A company wants to reduce costs by using an EC2 instance that will not be interrupted and provides a lower price than on-demand instances. Which instance type should they use?

• A. Reserved instances
