Question # 105

A company is running a data-intensive application on AWS. The application runs on a cluster of hundreds of Amazon EC2 instances. A shared file system also runs on several EC2 instances that store 200 TB of data. The application reads and modifies the data on the shared file system and generates a report. The job runs once monthly, reads a subset of the files from the shared file system, and takes about 72 hours to complete. The compute instances scale in an Auto Scaling group, but the instances that host the shared file system run continuously. The compute and storage instances are all in the same AWS Region.

A solutions architect needs to reduce costs by replacing the shared file system instances. The file system must provide high performance access to the needed data for the duration of the 72-hour run.

Which solution will provide the LARGEST overall cost reduction while meeting these requirements?

Migrate the data from the existing shared file system to an Amazon S3 bucket that uses the S3 Intelligent-Tiering storage class. Before the job runs each month, use Amazon FSx for Lustre to create a new file system with the data from Amazon S3 by using lazy loading. Use the new file system as the shared storage for the duration of the job. Delete the file system when the job is complete.

Migrate the data from the existing shared file system to a large Amazon Elastic Block Store (Amazon EBS) volume with Multi-Attach enabled. Attach the EBS volume to each of the instances by using a user data script in the Auto Scaling group launch template. Use the EBS volume as the shared storage for the duration of the job. Detach the EBS volume when the job is complete.

Migrate the data from the existing shared file system to an Amazon S3 bucket that uses the S3 Standard storage class. Before the job runs each month, use Amazon FSx for Lustre to create a new file system with the data from Amazon S3 by using batch loading. Use the new file system as the shared storage for the duration of the job. Delete the file system when the job is complete.

Migrate the data from the existing shared file system to an Amazon S3 bucket. Before the job runs each month, use AWS Storage Gateway to create a file gateway with the data from Amazon S3. Use the file gateway as the shared storage for the job. Delete the file gateway when the job is complete.

Question # 106

A company is hosting a monolithic REST-based API for a mobile app on five Amazon EC2 instances in public subnets of a VPC. Mobile clients connect to the API by using a domain name that is hosted on Amazon Route 53. The company has created a Route 53 multivalue answer routing policy with the IP addresses of all the EC2 instances. Recently, the app has been overwhelmed by large and sudden increases to traffic. The app has not been able to keep up with the traffic.

A solutions architect needs to implement a solution so that the app can handle the new and varying load.

Which solution will meet these requirements with the LEAST operational overhead?

Separate the API into individual AWS Lambda functions. Configure an Amazon API Gateway REST API with Lambda integration for the backend. Update the Route 53 record to point to the API Gateway API.

Containerize the API logic. Create an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. Run the containers in the cluster by using Amazon EC2. Create a Kubernetes ingress. Update the Route 53 record to point to the Kubernetes ingress.

Create an Auto Scaling group. Place all the EC2 instances in the Auto Scaling group. Configure the Auto Scaling group to perform scaling actions that are based on CPU utilization. Create an AWS Lambda function that reacts to Auto Scaling group changes and updates the Route 53 record.

Create an Application Load Balancer (ALB) in front of the API. Move the EC2 instances to private subnets in the VPC. Add the EC2 instances as targets for the ALB. Update the Route 53 record to point to the ALB.

Question # 107

A company has automated the nightly retraining of its machine learning models by using AWS Step Functions. The workflow consists of multiple steps that use AWS Lambda Each step can fail for various reasons and any failure causes a failure of the overall workflow

A review reveals that the retraining has failed multiple nights in a row without the company noticing the failure A solutions architect needs to improve the workflow so that notifications are sent for all types of failures in the retraining process

Which combination of steps should the solutions architect take to meet these requirements? (Select THREE)

Create an Amazon Simple Notification Service (Amazon SNS) topic with a subscription of type " Email " that targets the team ' s mailing list.

Create a task named " Email " that forwards the input arguments to the SNS topic

Add a Catch field all Task Map. and Parallel states that have a statement of " Error Equals " : [ â€œStates. ALLâ€] and " Next " : " Email " .

Add a new email address to Amazon Simple Email Service (Amazon SES). Verify the email address.

Create a task named " Email " that forwards the input arguments to the SES email address

Add a Catch field to all Task Map, and Parallel states that have a statement of " Error Equals " : [ " states. Runtimeâ€] and " Next " : " Email " .

Question # 108

A company is using AWS CloudFormation as its deployment tool for all applications. It stages all application binaries and templates within Amazon S3 buckets with versioning enabled. Developers use an Amazon EC2 instance with IDE access to modify and test applications. The developers want to implement CI/CD with AWS CodePipeline with the following requirements:

Use AWS CodeCommit for source control.

Automate unit testing and security scanning.

Alert developers when unit tests fail.

Toggle application features and allow lead developer approval before deployment.

Which solution will meet these requirements?

Use AWS CodeBuild for testing and scanning. Use EventBridge and SNS for alerts. Use AWS CDK with a manifest to toggle features. Use a manual approval stage.

Use Lambda for testing and alerts. Use AWS Amplify plugins for feature toggles. Use SES for manual approval.

Use Jenkins and SES for alerts. Use nested CloudFormation stacks for features. Use Lambda for approvals.

Use CodeDeploy for testing and scanning. Use CloudWatch alarms and SNS. Use Docker images for features and AWS CLI for toggles.

Question # 109

A companyâ€™s web application uses an Amazon API Gateway API, AWS Lambda functions, and Amazon DynamoDB global tables to handle backend requests. The web application is deployed in two AWS Regions in an active-passive model. The company uses Amazon Route 53 for DNS. The web application requires a manual DNS update to fail over to the secondary Region. An analytics Lambda function runs in the same AWS account. The function has caused Lambda concurrency to reach 90% of the current quota on an average day. A recent surge in traffic for the analytics workload resulted in throttled Lambda requests and a poor user experience for the web application users. A solutions architect must increase the reliability of the web application. The solution must use an Amazon CloudWatch alarm to send an Amazon SNS notification when the Lambda concurrency reaches a specific utilization threshold. Which solution will meet these requirements with the LEAST operational overhead?

Set reserved concurrency on the web application Lambda functions. Implement Route 53 health checks and failover records to route traffic to the secondary Region. Configure the CloudWatch alarm to use the AWS Trusted Advisor ServiceLimitUsage metric and to send the SNS notification.

Set reserved concurrency on the web application Lambda functions. Implement Route 53 health checks and latency records to route traffic to the secondary Region. Configure the CloudWatch alarm to use the AWS Trusted Advisor ServiceLimitUsage metric and to send an SNS notification.

Set provisioned concurrency on the web application Lambda functions. Implement Route 53 health checks and failover records to route traffic to the secondary Region. Configure the CloudWatch alarm to use the Lambda ConcurrentExecutions metric and to send an SNS notification.

Set provisioned concurrency on the web application Lambda functions. Implement Route 53 health checks and geolocation records to route traffic to the secondary Region. Configure the CloudWatch alarm to use the Lambda ProvisionedConcurrencyInvocations metric and to send an SNS notification.

Question # 111

A company has multiple AWS accounts and manages these accounts with AWS Organizations. A developer was given IAM user credentials to access AWS resources. The developer should have read-only access to all Amazon S3 buckets in the account. However, when the developer tries to access the S3 buckets from the console, they receive an access denied error message with no buckets listed.

A solutions architect reviews the permissions and finds that the developerâ€™s IAM user is listed as having read-only access to all S3 buckets in the account.

Which additional steps should the solutions architect take to troubleshoot the issue? (Select TWO.)

Check the bucket policies for all S3 buckets.

Check the ACLs for all S3 buckets.

Check the SCPs set at the organizational units (OUs).

Check for the permissions boundaries set for the IAM user.

Check if an appropriate IAM role is attached to the IAM user.

Question # 112

A company needs to implement a disaster recovery (DR) plan for a web application. The application runs in a single AWS Region.

The application uses microservices that run in containers. The containers are hosted on AWS Fargate in Amazon Elastic Container Service (Amazon ECS). The application has an Amazon RDS for MYSQL DB instance as its data layer and uses Amazon Route 53 for DNS resolution. An Amazon CloudWatch alarm invokes an

Amazon EventBridge rule if the application experiences a failure.

A solutions architect must design a DR solution to provide application recovery to a separate Region. The solution must minimize the time that is necessary to recover

from a failure.

Which solution will meet these requirements?

Set up a second ECS cluster and ECS service on Fargate in the separate Region. Create an AWS Lambda function to perform the following actions: take asnapshot of the ROS DB instance. copy the snapshot to the separate Region. create a new RDS DB instance frorn the snapshot, and update Route 53 toroute traffic to the second ECS cluster. Update the EventBridge rule to add a target that will invoke the Lambda function.
