A company has an on-premises SFTP file transfer solution. The company is migrating to the AWS Cloud to scale the file transfer solution and to optimize costs by using Amazon S3. The company's employees will use their credentials for the on-premises Microsoft Active Directory (AD) to access the new solution. The company wants to keep the current authentication and file access mechanisms.

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

A. Configure an S3 File Gateway. Create SMB file shares on the file gateway that use the existing Active Directory to authenticate.
B. Configure an Auto Scaling group with Amazon EC2 instances to run an SFTP solution. Configure the group to scale up at 60% CPU utilization.
C. Create an AWS Transfer Family server with SFTP endpoints. Choose the AWS Directory Service option as the identity provider. Use AD Connector to connect the on-premises Active Directory.
D. Create an AWS Transfer Family SFTP endpoint. Configure the endpoint to use the AWS Directory Service option as the identity provider to connect to the existing Active Directory.

A company is using AWS to design a web application that will process insurance quotes. Users will request quotes from the application. Quotes must be separated by quote type, must be responded to within 24 hours, and must not get lost. The solution must maximize operational efficiency and must minimize maintenance.

Which solution meets these requirements?

A. Create multiple Amazon Kinesis data streams based on the quote type. Configure the web application to send messages to the proper data stream. Configure each backend group of application servers to use the Kinesis Client Library (KCL) to pool messages from its own data stream.
B. Create an AWS Lambda function and an Amazon Simple Notification Service (Amazon SNS) topic for each quote type. Subscribe the Lambda function to its associated SNS topic. Configure the application to publish requests for quotes to the appropriate SNS topic.
C. Create a single Amazon Simple Notification Service (Amazon SNS) topic. Subscribe Amazon Simple Queue Service (Amazon SQS) queues to the SNS topic. Configure SNS message filtering to publish messages to the proper SQS queue based on the quote type. Configure each backend application server to use its own SQS queue.
D. Create multiple Amazon Kinesis Data Firehose delivery streams based on the quote type to deliver data streams to an Amazon OpenSearch Service cluster. Configure the application to send messages to the proper delivery stream. Configure each backend group of application servers to search for the messages from OpenSearch Service and process them accordingly.

A company runs its applications on Amazon EC2 instances that are backed by Amazon Elastic Block Store (Amazon EBS). The EC2 instances run the most recent Amazon Linux release. The applications are experiencing availability issues when the company's employees store and retrieve files that are 25 GB or larger. The company needs a solution that does not require the company to transfer files between EC2 instances. The files must be available across many EC2 instances and across multiple Availability Zones.

Which solution will meet these requirements?

A. Migrate all the files to an Amazon S3 bucket. Instruct the employees to access the files from the S3 bucket.
B. Take a snapshot of the existing EBS volume. Mount the snapshot as an EBS volume across the EC2 instances. Instruct the employees to access the files from the EC2 instances.
C. Mount an Amazon Elastic File System (Amazon EFS) file system across all the EC2 instances. Instruct the employees to access the files from the EC2 instances.
D. Create an Amazon Machine Image (AMI) from the EC2 instances. Configure new EC2 instances from the AMI that use an instance store volume. Instruct the employees to access the files from the EC2 instances.

A company stores its data objects in Amazon S3 Standard storage. A solutions architect has found that 75% of the data is rarely accessed after 30 days. The company needs all the data to remain immediately accessible with the same high availability and resiliency, but the company wants to minimize storage costs.

Which storage solution will meet these requirements?

A. Move the data objects to S3 Glacier Deep Archive after 30 days.
B. Move the data objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days.
C. Move the data objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 30 days.
D. Move the data objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) immediately.

A company wants to use Amazon Elastic Container Service (Amazon ECS) to run its on-premises application in a hybrid environment. The application currently runs on containers on premises.

The company needs a single container solution that can scale in an on-premises, hybrid, or cloud environment. The company must run new application containers in the AWS Cloud and must use a load balancer for HTTP traffic.

Which combination of actions will meet these requirements? (Choose two.)

A. Set up an ECS cluster that uses the AWS Fargate launch type for the cloud application containers. Use an Amazon ECS Anywhere external launch type for the on-premises application containers.
B. Set up an Application Load Balancer for cloud ECS services.
C. Set up a Network Load Balancer for cloud ECS services.
D. Set up an ECS cluster that uses the AWS Fargate launch type. Use Fargate for the cloud application containers and the on-premises application containers.
E. Set up an ECS cluster that uses the Amazon EC2 launch type for the cloud application containers. Use Amazon ECS Anywhere with an AWS Fargate launch type for the on-premises application containers.

A company runs workloads in the AWS Cloud. The company wants to centrally collect security data to assess security across the entire company and to improve workload protection.

Which solution will meet these requirements with the LEAST development effort?

A. Configure a data lake in AWS Lake Formation. Use AWS Glue crawlers to ingest the security data into the data lake.
B. Configure an AWS Lambda function to collect the security data in .csv format. Upload the data to an Amazon S3 bucket.
C. Configure a data lake in Amazon Security Lake to collect the security data. Upload the data to an Amazon S3 bucket.
D. Configure an AWS Database Migration Service (AWS DMS) replication instance to load the security data into an Amazon RDS cluster.

A company is designing its production application's disaster recovery (DR) strategy. The application is backed by a MySQL database on an Amazon Aurora cluster in the us-east-1 Region. The company has chosen the us-west-1 Region as its DR Region.

The company's target recovery point objective (RPO) is 5 minutes and the target recovery time objective (RTO) is 20 minutes. The company wants to minimize configuration changes.

Which solution will meet these requirements with the MOST operational efficiency?

A. Create an Aurora read replica in us-west-1 similar in size to the production application's Aurora MySQL cluster writer instance.
B. Convert the Aurora cluster to an Aurora global database. Configure managed failover.
C. Create a new Aurora cluster in us-west-1 that has Cross-Region Replication.
D. Create a new Aurora cluster in us-west-1. Use AWS Database Migration Service (AWS DMS) to sync both clusters.
