Question #26 / 1019

A company must maintain a historical record of its AWS resource configurations to meet compliance requirements and audit for unauthorized modifications. Which service should be implemented to continuously monitor and log configuration changes across all Amazon S3 buckets?

A

Enable AWS Config with compliance rules to track and record configuration changes.

B

Enable AWS CloudTrail to log all API calls related to S3 bucket configurations.

C

Enable Amazon CloudWatch alarms to detect unauthorized configuration changes.

D

Enable AWS Security Hub to aggregate findings from multiple security services.

Question #272 / 1019

A company hosts a dynamic web application on Amazon EC2 instances behind an Application Load Balancer (ALB) in the eu-west-1 region. Users in different regions report varying latency, especially on mobile devices. The company wants to improve performance globally without replicating the infrastructure across multiple regions. The application serves different content based on the User-Agent header to optimize for mobile or desktop users. What should a solutions architect do to meet these requirements?

A

Replace the existing architecture with a static website hosted on Amazon S3. Configure an Amazon CloudFront distribution with the S3 bucket as the origin. Set the cache behavior to cache based on the User-Agent request header.

B

Configure an Amazon CloudFront distribution with the ALB as the origin. Set the cache behavior settings to cache based on the User-Agent request header.

C

Create an Amazon API Gateway API integrated with the ALB using HTTP integration. Enable API Gateway caching based on the User-Agent header.

D

Deploy EC2 instances in additional Regions and configure a caching layer using Varnish. Use Amazon Route 53 with a geolocation routing policy to direct traffic.

Sample Questions

Question #101 / 529

A company is running applications on AWS in a multi-account setup under AWS Organizations. The development team and analytics team operate in separate AWS accounts. The development team stores terabytes of sensitive data in an Amazon S3 bucket encrypted with an AWS KMS key. The analytics team uses Amazon Redshift for data processing and requires access to the development team's S3 bucket. The analytics team has already configured an IAM role for Amazon Redshift in their account. The company needs a secure cross-account solution with minimal operational overhead.

A

Create a new S3 bucket in the analytics account. Configure S3 replication rules in the development account to copy data to the analytics account's bucket. Update the Redshift permissions in the analytics account to access the replicated bucket.

B

Use an SCP to grant the analytics account access to the S3 bucket. Share the KMS key via AWS Resource Access Manager (AWS RAM) from the development account to the analytics account. Modify the Redshift IAM role to include permissions for the S3 bucket.

C

Update the S3 bucket policy in the development account to grant the Redshift role access. Create a KMS grant for the encryption key to allow the Redshift role to decrypt data. Adjust the Redshift permissions to include the S3 bucket.

D

Create an IAM role in the development account with access to the S3 bucket and KMS key. Configure the Redshift role in the analytics account to assume the development account's IAM role. Update the KMS key policy to allow the Redshift role to use the key.

Question #154 / 529

A company operates a data processing pipeline using an AWS Lambda function. The function configures batch size and timeout settings through environment variables. The company frequently updates these variables to optimize performance. After validating new settings, they publish a new Lambda version and update their application to invoke the new version's ARN. This process causes application downtime during updates.

A solutions architect must streamline this process to eliminate downtime with minimal operational overhead.

Which solution meets these requirements?

A

Modify the environment variables of the existing Lambda function version. Use the $LATEST version for testing new configurations.

B

Store the batch size and timeout settings in an Amazon RDS database. Update the Lambda function to fetch parameters from the database.

C

Hardcode the configuration parameters within the Lambda function code. Publish a new version each time parameters are updated.

D

Create a Lambda function alias. Configure the application to use the alias ARN. Update the alias to point to new versions after testing.

Sample Questions

Question #5 / 557

A developer has created an AWS Lambda function written in Python that processes data from an API Gateway and writes logs to Amazon CloudWatch. The function is successfully triggered by API Gateway, but no logs appear in CloudWatch. What is the MOST likely cause of this issue?

A

The Lambda function's execution role lacks permissions to write to CloudWatch Logs.

B

CloudWatch Logs requires a specific retention period setting.

C

The Lambda function is not configured with the correct environment variables.

D

The Lambda function's memory setting is too low.

Question #526 / 557

An application is designed to consume messages from an Amazon SQS standard queue using AWS Fargate tasks in Amazon ECS. The development team wants to optimize the solution for cost-effectiveness while ensuring efficient message processing.

Which two actions should be taken to achieve this goal? (Choose two.)

A

Configure the SQS queue to use long polling when retrieving messages.

B

Set the SQS queue to use short polling for faster message retrieval.

C

Retrieve messages in batches using the maximum number of messages per API call.

D

Implement an Amazon ElastiCache cluster to store messages temporarily.

E

Use an SQS FIFO queue to ensure messages are processed exactly once.
