Sample Exam Questions
To give candidates a sense of what to expect, here are a few sample questions:
Question 1: Your company has a web application deployed in an AWS Auto Scaling group. Users report slow performance during peak hours. What is the best solution to improve performance?
A. Configure a dynamic scaling policy based on CPU utilization.
B. Configure a scheduled scaling policy to launch instances before peak hours.
C. Configure a predictive scaling policy to adjust the number of instances automatically.
D. Configure a dynamic scaling policy based on memory utilization.
Answer: B. Configuring a scheduled scaling policy ensures that additional instances are available before peak usage, improving performance during high-demand periods.
Question 2: You need to allow a web application hosted in an Amazon S3 bucket to make authenticated HTTP GET requests using JavaScript. What should you implement?
A. Enable cross-account access.
B. Enable Cross-Origin Resource Sharing (CORS) configuration in the bucket.
C. Enable Cross-Zone Load Balancing.
D. Enable Cross-Region Replication (CRR).
Answer: B. Enabling CORS allows the web application to make requests to the S3 bucket from a different origin, which is necessary for JavaScript execution in browsers.
Question 3: A tech company wants to ensure that their data stored in Amazon S3 is automatically backed up to another region. What is the best solution?
A. Enable versioning on the S3 bucket.
B. Use AWS Backup to create a backup plan for the S3 bucket.
C. Enable Cross-Region Replication (CRR) on the S3 bucket.
D. Use AWS DataSync to copy data to another region.
Answer: C. Enabling Cross-Region Replication (CRR) automatically replicates objects across different AWS regions, ensuring data redundancy and availability.
Preparation Strategies
To prepare effectively for the AWS Certified Solutions Architect - Associate exam, candidates should consider the following strategies:
Hands-On Experience: Gain practical experience by working with AWS services. Use the AWS Free Tier to experiment with different services and architectures.
Study Resources: Utilize AWS documentation, whitepapers, and online courses. AWS offers official practice exams and training resources that can help reinforce knowledge and skills.
