Question #70 / 1019

A company's HTTPS application is behind a Network Load Balancer (NLB). The NLB's target group uses an EC2 Auto Scaling group with multiple instances hosting the service. The NLB is configured with TCP health checks on port 443. The company observes that occasional HTTP 500 errors from the application are not detected by the NLB, leading to manual instance restarts. They need an automated solution without custom code to improve availability.

What should a solutions architect recommend to address this issue?

A

Update the NLB's health checks to use HTTPS and provide the application's health check URL. Configure Auto Scaling to replace instances marked unhealthy.

B

Create a CloudWatch alarm monitoring the HTTPCodeBackend5XX metric. Link the alarm to an Auto Scaling policy to replace instances when the alarm triggers.

C

Replace the NLB with an Application Load Balancer (ALB). Configure HTTP health checks with the application's URL and enable Auto Scaling to replace unhealthy instances.

D

Add a systemd service to each EC2 instance to monitor application logs for 500 errors and restart the service automatically when detected.

Question #446 / 1019

A company stores sensitive financial records in an Amazon S3 bucket. Regulatory requirements mandate that all data must be retained immutably for 5 years, including existing objects. Which solution ensures compliance with the LEAST operational effort?

A

Enable S3 Versioning and configure a Lifecycle policy to delete objects after 5 years. Implement MFA delete for additional protection.

B

Activate S3 Object Lock in governance mode with a 5-year retention period. Manually recopy all existing objects to apply retention settings.

C

Enable S3 Object Lock in compliance mode with a 5-year retention period. Manually recopy all existing objects to enforce retention.

D

Activate S3 Object Lock in compliance mode with a 5-year retention period. Use S3 Batch Operations to apply retention settings to all existing objects.

Question #229 / 529

A solutions architect is migrating critical Oracle databases to AWS. These databases are part of legacy systems, and the architect must transition them to a modern data architecture with near-zero downtime. Which solution meets these requirements?

A

Use AWS Application Migration Service and the AWS Schema Conversion Tool (AWS SCT). Perform an in-place upgrade before migration. Export the data to Amazon Aurora Serverless after cutover and repoint applications to Aurora.

B

Use AWS Database Migration Service (AWS DMS) to rehost the database with Amazon S3 as the target. Configure change data capture (CDC) replication. Once synchronized, load the data into an Amazon RDS for Oracle DB instance.

C

Use Oracle Data Guard for replication. Connect the source database to an Amazon RDS for Oracle DB instance. After synchronization, transition the workload to the RDS instance.

D

Use AWS Application Migration Service to rehost the database on Amazon EC2. After replication, detach the database, migrate it to an Amazon RDS for Oracle DB instance, reattach it, and cut over networking.

Question #107 / 529

A company operates a serverless application where an Amazon API Gateway in the eu-west-1 region triggers an AWS Lambda function. The current setup lacks regional redundancy. A solutions architect must redesign the architecture to enable automatic failover to another AWS Region in case of an outage. Which solution meets these requirements?

A

Set up a new API Gateway in eu-central-1 that invokes the existing Lambda function in eu-west-1. Use Amazon Route 53 with failover routing to direct traffic between the two API Gateways.

B

Implement an Amazon SNS topic to handle incoming requests. Configure the Lambda function to process messages from the SNS topic. Replicate the SNS topic and Lambda function in eu-central-1 and use Route 53 for DNS failover.

C

Deploy the Lambda function in eu-central-1 and create an API Gateway there. Use AWS Global Accelerator with an Application Load Balancer to distribute traffic across both regions.

D

Deploy the Lambda function and API Gateway in eu-central-1. Configure Amazon Route 53 with a failover routing policy to route traffic between the two API Gateway endpoints in each region.

Sample Questions

Question #502 / 557

A company manages SSL certificates using AWS Certificate Manager (ACM) for their public-facing applications. The security team needs to receive notifications 90 days before any certificate expires. The company has an existing Amazon SNS topic subscribed by the security team's email and an Amazon SQS queue configured for other alerts.

Which solution ensures the security team is notified on time?

A

Set up an Amazon EventBridge rule that triggers on the 'ACM Certificate Expired' event. Configure the SNS topic as the target.

B

Develop an AWS Lambda function that lists all ACM certificates daily, checks their expiration dates, and publishes a message to the SQS queue for certificates expiring within 90 days.

C

Use AWS Config to enable the 'acm-certificate-expiration-check' managed rule, setting the threshold to 90 days. Create an EventBridge rule that triggers on compliance change events from AWS Config, targeting the SNS topic.

D

Configure an Amazon CloudWatch alarm based on the ACM 'DaysToExpiry' metric, set the threshold to 90, and set the SNS topic as the alarm action.

Question #472 / 557

A developer is troubleshooting an AWS Lambda function triggered by an Amazon Simple Queue Service (Amazon SQS) queue. The Lambda function processes messages in batches, but some messages are becoming visible in the queue again before processing completes, leading to duplicate processing.

The developer needs to ensure messages remain hidden until processing finishes.

Which solution will resolve this issue?

A

Increase the maximum execution timeout of the Lambda function.

B

Increase the visibility timeout of the SQS queue.

C

Increase the ephemeral storage size of the Lambda function.

D

Increase the retry attempts in the event source mapping.
