Question #674 / 1019

A company operates a web application hosted on Amazon EC2 instances within an Auto Scaling group. The backend uses an Amazon RDS for MySQL DB instance. During peak traffic, the application's performance degrades, and the database encounters a significant increase in read operations.

Which two actions should a solutions architect take to address these performance issues? (Choose two.)

A

Enable automatic scaling for the RDS DB instance to handle increased load.

B

Set up a read replica for the RDS DB instance and direct read queries to it.

C

Implement a Multi-AZ deployment for the DB instance and route read traffic to the standby instance.

D

Deploy an Amazon ElastiCache cluster to cache frequent database queries.

E

Modify the Auto Scaling group to launch EC2 instances in the same Availability Zone as the DB instance.

Question #191 / 1019

A retail company uses an inventory management system backed by Amazon RDS for MySQL. During peak sales periods, employees execute real-time analytical queries for stock monitoring, causing transaction timeouts in the order fulfillment process. The company wants to resolve the timeouts without restricting employee access to real-time analytics.

A

Create a read replica. Route analytical queries to the read replica.

B

Create a read replica. Split the inventory application's read and write operations between the primary DB instance and the read replica.

C

Migrate the inventory system to Amazon Aurora Serverless with auto-scaling capacity.

D

Limit analytical queries to predefined intervals during off-peak hours.

Sample Questions

Question #145 / 529

An international logistics company uses a delivery tracking system on AWS. Drivers upload delivery proofs, such as timestamps and geotags, via SFTP to a single Amazon EC2 instance. Each handheld device saves files in directories named after the driver’s ID, with filenames corresponding to shipment tracking numbers. The EC2 instance enriches the files by querying a central database for shipment details before archiving them in Amazon S3. As the company grows, drivers experience connection timeouts, and the EC2 instance faces high CPU usage. The operations team implemented a cron job to restart the instance hourly, but some files are missing in S3, and the database updates are inconsistent. A solutions architect must design a scalable solution to ensure all files are archived and systems updated. The handheld devices cannot be modified. Which solution meets these requirements?

A

Create an AMI of the EC2 instance. Deploy an Auto Scaling group of EC2 instances behind a Network Load Balancer. Use Amazon EFS for shared storage and configure scaling based on CPU utilization.

B

Use AWS Transfer Family to create an SFTP server that stores files in Amazon EFS. Mount the EFS volume to the existing EC2 instance and update the processing script to reference the new file path.

C

Use AWS Transfer Family to create an SFTP server that stores files in Amazon S3. Configure S3 event notifications via Amazon SNS to invoke an AWS Lambda function for metadata enrichment and database updates.

D

Modify the handheld devices to upload files directly to Amazon S3. Use S3 event notifications with Amazon SQS to trigger an AWS Lambda function for processing and system updates.

Question #208 / 529

A software-as-a-service (SaaS) provider uses an Application Load Balancer (ALB) to expose APIs hosted on an Amazon Elastic Kubernetes Service (EKS) cluster in the eu-west-1 Region. The APIs utilize non-standard REST methods such as PURGE, CHECKOUT, MERGE, and COPY. Users in Asia and South America report high latency and inconsistent performance. A solutions architect must address the latency issue while minimizing operational complexity. Which solution meets these requirements?

B

Deploy an Amazon API Gateway regional REST API to front the ALB. Configure integration mappings for the non-standard methods.

A

Create an Amazon CloudFront distribution with the ALB as the origin. Configure cache behaviors to forward the non-standard HTTP methods.

C

Use AWS Global Accelerator with the ALB as an endpoint group. Enable client affinity for consistent routing.

D

Replicate the EKS cluster to ap-southeast-1 and sa-east-1 Regions. Use Amazon Route 53 geolocation routing to direct traffic.

Sample Questions

Question #193 / 557

A developer is building a mobile application that allows guest users to access features without any form of authentication. What is the MOST secure way to provide temporary access to AWS resources for these users?

A

Integrate a third-party identity provider to issue temporary credentials for AWS resource access.

B

Use AWS CloudFormation to dynamically provision IAM users for each guest session.

C

Generate short-lived credentials via AWS STS and embed them directly in the application code.

D

Configure Amazon Cognito to assign unauthenticated users an IAM role with restricted permissions.

Question #83 / 557

A developer has configured an AWS Lambda function to process data files uploaded to an Amazon S3 bucket. The Lambda function is designed to trigger whenever a new .csv file larger than 100 MB is uploaded. The developer tested the function by uploading a 150 MB .csv file via the AWS CLI, and it executed successfully. However, when a user uploads a 200 MB .csv file through the S3 console, the Lambda function does not trigger.

Which of the following is a possible reason for this failure?

A

S3 event notifications do not support console uploads for files larger than 100 MB.

B

The resource-based policy for the Lambda function does not allow Amazon S3 to invoke it.

C

Lambda functions cannot be triggered by S3 events for objects stored in the Standard storage class.

D

The S3 bucket's lifecycle policy is set to transition objects to Glacier immediately.
