Question #328 / 1019

A company hosts a three-tier ecommerce application on AWS. The frontend is served from Amazon S3, integrated with an API hosted on EC2 instances behind an Application Load Balancer. The API serves static assets and dynamic requests, with backend processors handling orders asynchronously. The company expects a sudden surge in traffic during holiday sales and wants to ensure all requests are processed efficiently.

What should a solutions architect recommend to handle the traffic spike effectively?

A

Use Amazon CloudFront to cache dynamic content. Manually increase the number of EC2 instances before the event.

B

Use Amazon CloudFront to cache static content. Configure an Auto Scaling group for EC2 instances scaling based on CPU utilization.

C

Use Amazon CloudFront to cache dynamic content. Deploy an Amazon ElastiCache cluster to store session data and reduce API load.

D

Use Amazon CloudFront to cache static content. Implement Amazon SQS to queue incoming orders for asynchronous processing by EC2 workers.

Question #275 / 1019

A company hosts a web application on Amazon EC2 instances behind an Application Load Balancer. The instances are managed by an EC2 Auto Scaling group distributed across multiple Availability Zones. The Auto Scaling group scales up to 25 instances during peak traffic periods but scales down to 4 instances during low-traffic hours. Users are experiencing high latency during sudden traffic surges, though the application stabilizes after a short period.

How should the scaling policy be modified to mitigate latency during traffic surges while maintaining cost efficiency?

A

Implement a scheduled action to increase the desired capacity to 25 just before peak traffic begins.

B

Configure a step scaling policy activated at a higher CPU utilization threshold and reduce the cooldown period.

C

Configure a target tracking policy with a lower CPU utilization threshold and reduce the cooldown period.

D

Implement a scheduled action to set the minimum and maximum capacity to 25 before peak traffic starts.

Question #203 / 529

A company needs to migrate a 50 TB on-premises Microsoft SQL Server database to Amazon RDS for SQL Server in the us-west-2 Region. Their current internet connection has low bandwidth, leading to an estimated transfer time of six weeks. The company requires a solution that minimizes migration time.

Which solution achieves the fastest migration?

A

Set up a 10 Gbps AWS Direct Connect link and use AWS DMS to migrate the database.

B

Use AWS DataSync over the existing connection to transfer data, then use AWS Application Migration Service for the database migration.

C

Ship an AWS Snowball Edge device to transfer data to Amazon S3, then use AWS DMS to migrate from S3 to RDS.

D

Use multiple AWS Snowball devices with the S3 Adapter, then AWS Application Migration Service to migrate data from S3.

Question #149 / 529

A company must grant a third-party monitoring service read-only access to its AWS resources. The third party uses a single AWS account, and the solution must adhere to AWS security best practices while ensuring no long-term credentials are shared. A solutions architect needs to implement the most secure approach.

A

In the company's AWS account, create S3 bucket policies and IAM policies granting read-only access to the third party's AWS account. Include a unique external ID in each resource policy.

B

In the company's AWS account, create an IAM role that establishes a trust relationship with the third party's AWS account. Attach a read-only IAM policy to the role and include a unique external ID in the role's trust policy.

C

In the company's AWS account, create an IAM user with read-only permissions. Generate access keys for the IAM user and share them securely with the third party.

D

In the company's AWS account, create an IAM group with read-only permissions. Add IAM users for each third-party administrator to the group.

Sample Questions

Question #302 / 557

A company operates a serverless data analytics application on AWS. The application uses an AWS Lambda function to process and load data into an Amazon Redshift cluster. The Lambda function accesses the Redshift cluster using a set of database credentials. A developer needs to manage these credentials securely using AWS Secrets Manager and ensure the password is rotated regularly without causing downtime or disruption to the data loading process.

What should the developer implement to meet these requirements?

A

Configure Secrets Manager rotation with the single user strategy, updating the credentials directly in Redshift.

B

Configure Secrets Manager rotation with the alternating users strategy, maintaining two separate credentials in Redshift.

C

Enable automatic rotation using the single user strategy and update the Lambda function's environment variables manually.

D

Enable automatic rotation using the alternating users strategy and ensure the Lambda function references the Secrets Manager secret.

Question #50 / 557

A developer is testing error handling for a mobile app that interacts with an Amazon API Gateway REST API. The developer needs to simulate various HTTP error responses (e.g., 400, 500) during testing without triggering the actual backend service.

Which approach fulfills these requirements with the LEAST operational overhead?

A

Deploy an AWS Lambda function with error-throwing logic. Integrate it with API Gateway using proxy integration.

B

Set up an Amazon ECS cluster with containers that return predefined error codes. Configure API Gateway to route to the ECS service.

C

Modify the API Gateway resource methods to return hardcoded error responses using gateway responses.

D

Use API Gateway mock integrations with context variables in mapping templates to dynamically generate error responses.
