Sample Questions

Question #776 / 1019

A company runs a social media application that retrieves user profile data from an Amazon RDS MySQL instance. With a surge in users, the application experiences increased latency during profile data fetches. Performance analysis shows that scaling the database isn't resolving the issue. A solutions architect needs to implement a solution that supports point-in-time recovery, cross-region replication, and delivers responses in under a millisecond.

What should the solutions architect recommend to address these requirements?

A

Migrate the database to Amazon Aurora with Multi-Region read replicas.

B

Migrate the database to Amazon DynamoDB with global tables.

C

Add an Amazon ElastiCache for Redis layer in front of the database.

D

Add an Amazon ElastiCache for Memcached layer in front of the database.

Question #144 / 1019

A social media analytics platform uses Amazon Aurora as its primary database. During peak analytics processing times, the application experiences latency issues. Amazon CloudWatch metrics show significant spikes in Read IOPS and CPU Utilization when analytics queries are executed. What is the MOST cost-effective solution?

A

Migrate the analytics processing workload to Amazon Redshift.

B

Route analytics queries to an Aurora Replica using the reader endpoint.

C

Increase the Provisioned IOPS capacity for the Aurora database.

D

Upgrade the Aurora database instance to a larger instance class.

Sample Questions

Question #100 / 529

A company's e-commerce platform experiences prolonged delays during peak traffic due to synchronous calls to a third-party payment gateway. The current architecture directly invokes an AWS Fargate task for each transaction, leading to bottlenecks and failed payments. A solutions architect must decouple the payment processing system and ensure all transactions are eventually processed without dropping requests. Which solution meets these requirements?

A

Use an Amazon Simple Queue Service (Amazon SQS) queue to buffer payment requests and asynchronously trigger the Fargate tasks.

B

Use an AWS Step Functions state machine to orchestrate the payment processing workflow with the Fargate tasks.

C

Use an Amazon EventBridge rule to schedule the Fargate tasks for processing payment requests.

D

Use an Amazon Simple Notification Service (Amazon SNS) topic to fan out payment requests to multiple Fargate tasks.

Question #448 / 529

A company is deploying a new web-based application and needs a storage solution for the Linux application servers. The company wants a single location for updates to application data across all instances. The active dataset will be up to 200 GB in size. A solutions architect determined that peak operations will occur for 4 hours daily, requiring a total of 300 MiBps of read throughput.

The solution must be Multi-AZ and replicate data to another AWS Region for DR with an RPO of less than 1 hour.

Which solution meets these requirements?

A

Deploy Amazon EFS Multi-AZ file system with 100 MiBps provisioned throughput. Replicate to DR Region.

B

Deploy Amazon FSx for Windows with Bursting Throughput. Use AWS Backup for DR.

C

Use EBS gp3 volume with 300 MiBps throughput, Multi-Attach, and Elastic Disaster Recovery.

D

Deploy FSx for OpenZFS in both Regions with DataSync every 15 minutes.

Sample Questions

Question #295 / 557

A gaming company runs a real-time leaderboard application backed by an Amazon Aurora PostgreSQL database. The leaderboard data is updated continuously with complex player statistics and high-frequency interactions. The current architecture cannot serve read requests with low latency due to the rapidly changing data and high traffic volume. The company needs a solution to reduce read latency while ensuring data consistency.

Which solution will meet these requirements?

A

Use Amazon DynamoDB Accelerator (DAX) in front of the Aurora database to cache the frequently changing leaderboard data and reduce read latency.

B

Enable Amazon Aurora Global Database to replicate the leaderboard data across multiple AWS Regions and reduce latency for global users.

C

Deploy an Amazon CloudFront distribution configured to cache dynamic leaderboard data directly from the Aurora database at edge locations.

D

Implement an Amazon ElastiCache for Redis cluster. Modify the application to use a write-through caching strategy and retrieve data from Redis.

Question #425 / 557

A developer is troubleshooting latency issues in a distributed application composed of multiple microservices running on Amazon EC2 instances. The developer needs to trace requests across all microservices to identify the specific components causing delays and analyze performance bottlenecks.

What should the developer implement to achieve this goal?

A

Configure Amazon CloudWatch to collect custom metrics and logs from each microservice, then use CloudWatch dashboards to visualize latency data.

B

Enable AWS CloudTrail to log API calls across all microservices and analyze the logs to trace request paths and latency.

C

Integrate the AWS X-Ray SDK into all microservices to generate traces, then use X-Ray's service map and analytics to identify latency issues.

D

Use AWS Health Dashboard to monitor resource performance and identify EC2 instances contributing to latency problems.
