Understanding and practicing real exam questions is a crucial step in preparing for the AWS Certified Solutions Architect - Associate (SAA-C02) exam. Reviewing actual exam questions not only helps candidates familiarize themselves with the type and difficulty of the questions, but also deepens their understanding of AWS services and concepts. Here are sample questions and answers from the real AWS SAA-C02 exam:

QUESTION 1
A company wants to analyze and troubleshoot Access Denied errors and Unauthorized errors that are related to IAM permissions. The company has AWS 
CloudTrail turned on. Which solution will meet these requirements with the LEAST effort?
A. Use AWS Glue and write custom scripts to query Cloud Trail logs for the errors.
B. Use AWS Batch and write custom scripts to query CloudTrail logs for the errors.
C. Search CloudTrail logs with Amazon Athena queries to identify the errors.
D. Search CloudTrail logs with Amazon QuickSight. Create a dashboard to identify the errors.
Correct Answer: D

QUESTION 2
A company uses Amazon S3 as its data lake. The company has a new partner that must use SFTP to upload data files. A solutions architect needs to implement a 
highly available SFTP solution that minimizes operational overhead. Which solution will meet these requirements?
A. Use AWS Transfer Family to configure an SFTP-enabled server with a publicly accessible endpoint. Choose the S3 data lake as the destination.
B. Use Amazon S3 Fie Gateway as an SFTP server. Expose the S3 File Gateway endpoint URL to the new partner. Share the S3 File Gateway endpoint with the 
new partner.
C. Launch an Amazon EC2 instance in a private subnet in a VPC. Instruct the new partner to upload files to the EC2 instance by using a VPN. Run a cron job 
script on the EC2 instance to upload files to the S3 data lake.
D. Launch Amazon EC2 instances in a private subnet in a VPC. Place a Network Load Balancer (NLB) in front of theEC2 instances. Create an SFTP listener port 
for the NLB. Share the NLB hostname with the new partner. Run a cron job script on the EC2 instances to upload files to the S3 data lake.
Correct Answer: D

QUESTION 3
A company is migrating its on-premises PostgreSQL database to Amazon Aurora PostgreSQL. The on-premises database must remain online and accessible 
during the migration. The Aurora database must remain synchronized with the on-premises database. Which combination of actions must a solutions architect take 
to meet these requirements? (Select TWO.)
A. Create an ongoing replication task.
B. Create a database backup of the on-premises database.
C. Create an AWS Database Migration Service (AWS DMS) replication server.
D. Convert the database schema by using the AWS Schema Conversion Tool (AWS SCT).
E. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to monitor the database synchronization.
Correct Answer: CE

QUESTION 4
The customers of a finance company request appointments with financial advisors by sending text messages. A web application that runs on Amazon EC2 
instances accepts the appointment requests. The text messages are published to an Amazon Simple Queue Service (Amazon SQS) queue through the web 
application. Another application that runs on EC2 instances then sends meeting invitations and meeting confirmation email messages to the customers. After 
successful scheduling, this application stores the meeting information in an Amazon DynamoDB database. As the company expands, customers report that their 
meeting invitations are taking longer to arrive. What should a solutions architect recommend to resolve this issue?
A. Add a DynamoDB Accelerator (DAX) cluster in front of the DynamoDB database.
B. Add an Amazon API Gateway API in front of the web application that accepts the appointment requests.
C. Add an Amazon CloudFront distribution. Set the origin as the web application that accepts the appointment requests.
D. Add an Auto Scaling group for the application that sends meeting invitations. Configure the Auto Scaling group to scale based on the depth of the SQS queue.
Correct Answer: D

QUESTION 5
A company's application is having performance issues. The application is stateful and needs to complete in-memory tasks on Amazon EC2 instances. The 
company used AWS CloudFormation to deploy infrastructure and used the M5 EC2 instance family. As traffic increased, the application performance degraded. 
Users are reporting delays when the users attempt to access the application. Which solution will resolve these issues in the MOST operationally efficient way?
A. Replace the EC2 instances with T3 EC2 instances that run in an Auto Scaling group. Make the changes by using the AWS Management Console.
B. Modify the CloudFormation templates to run theEC2 instances in an Auto Scaling group. Increase the desired capacity and the maximum capacity of the Auto 
Scaling group manually when an increase is necessary.
C. Modify the CloudFormation templates. Replace the EC2 instances with R5 EC2 instances. Use Amazon CloudWatch built-in EC2 memory metrics future 
capacity planning.
D. Modify the CloudFormation templates. Replace the EC2 instances with R5 EC2 instances. Deploy the Amazon CloudWatch agent on the EC2 instances to 
generate custom application latency metrics for future capacity planning.
Correct Answer: D
