Question #820 / 1019

A company is migrating batch processing jobs from an on-premises environment to AWS. The jobs run on specific recurring schedules, with each job taking between 15 and 30 minutes to complete. The solution must require minimal code changes and support triggering jobs based on future events. Which approach meets these requirements?

A

Package the jobs into container images. Use Amazon EventBridge Scheduler to create recurring schedules and trigger the jobs as AWS Lambda functions.

B

Package the jobs into container images. Configure AWS Batch with Amazon ECS and a cron-based scheduling policy to execute the jobs.

C

Package the jobs into container images. Use Amazon EventBridge Scheduler to create recurring schedules and trigger the jobs as tasks on AWS Fargate.

D

Package the jobs into container images. Design an AWS Step Functions workflow with a Wait state to delay execution until a specified time. Use the RunTask action to execute the jobs on Amazon EC2 instances.

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.

Sample Questions

Question #468 / 529

A company stores application logs from multiple AWS regions in a centralized Amazon S3 bucket. The logs are in CSV format and compressed with gzip. The company uses Amazon Athena to query these logs for auditing purposes. Over time, query performance has degraded due to increasing data volume, and storage costs are rising. A solutions architect must optimize query performance and reduce storage costs without compromising data retention requirements.

Which solution will meet these requirements with the MOST significant improvement?

A

Create an AWS Lambda function to convert CSV files to Apache ORC format using Snappy compression. Configure the Lambda function to trigger automatically for new S3 uploads.

B

Enable S3 Transfer Acceleration for the bucket and apply an S3 Lifecycle policy to transition logs to S3 Glacier Deep Archive after 30 days.

C

Update the logging pipeline to store logs in Apache Parquet format partitioned by date. Configure daily partitioning for new log files.

D

Migrate to the latest Athena engine version and increase the Athena workgroup's query concurrency limit.

Question #442 / 529

A solutions architect has deployed a web application that serves users across two AWS Regions under a custom domain. The application uses Amazon Route 53 latency-based routing. The solutions architect has associated weighted record sets with a pair of web servers in separate Availability Zones for each Region. During a disaster recovery test, when all web servers in one Region are terminated, Route 53 does not automatically redirect users to the remaining Region. Which of the following are possible root causes of this issue? (Choose two.)

A

The weight for the terminated Region's weighted records is set lower than the weight for the active Region's records.

B

The health checks for the active Region's web servers are configured with an incorrect path.

C

Latency-based routing policies cannot be combined with weighted routing policies for the same domain.

D

The 'Evaluate Target Health' option is disabled for the latency alias records pointing to the terminated Region's weighted records.

E

The weighted records associated with the terminated Region's web servers do not have health checks configured.

Sample Questions

Question #237 / 557

A developer needs to encrypt sensitive log data locally before storing it in an Amazon S3 bucket. The encryption must use symmetric cryptography and be performed within the application without relying on external tools. How should the developer implement this encryption?

A

Generate an HMAC key in AWS KMS and use the AWS CLI to encrypt the logs.

B

Create a symmetric data key in AWS KMS and use the AWS Encryption SDK to encrypt the logs.

C

Generate an asymmetric data key pair in AWS KMS and use the AWS CLI for encryption.

D

Create a symmetric data key in AWS KMS and use OpenSSL commands to encrypt the logs.

Question #504 / 557

A developer is configuring an authorization mechanism using Amazon API Gateway and needs to test JSON Web Token (JWT) authorization without managing custom code. The developer must use the built-in authorizer and ensure the API has a route available at /auth. Which solution meets these requirements?

A

Create a WebSocket API with the /auth route, configure the JWT authorizer, attach it to the API, and deploy.

B

Create a WebSocket API with the /auth route, create an AWS Lambda authorizer, attach it to the API, and deploy.

C

Create an HTTP API with the /auth route, create an AWS Lambda authorizer, attach it to the /auth route, and deploy.
