An ecommerce company runs its application on AWS. The application uses an Amazon Aurora PostgreSQL cluster in Multi-AZ mode for the underlying database. During a recent promotional campaign, the application experienced heavy read load and write load. Users experienced timeout issues when they attempted to access the application.

A solutions architect needs to make the application architecture more scalable and highly available.

Which solution will meet these requirements with the LEAST downtime?

A. Create an Amazon EventBridge rule that has the Aurora cluster as a source. Create an AWS Lambda function to log the state change events of the Aurora cluster. Add the Lambda function as a target for the EventBridge rule. Add additional reader nodes to fail over to.
B. Modify the Aurora cluster and activate the zero-downtime restart (ZDR) feature. Use Database Activity Streams on the cluster to track the cluster status.
C. Add additional reader instances to the Aurora cluster. Create an Amazon RDS Proxy target group for the Aurora cluster.
D. Create an Amazon ElastiCache for Redis cache. Replicate data from the Aurora cluster to Redis by using AWS Database Migration Service (AWS DMS) with a write-around approach.

An online video game company must maintain ultra-low latency for its game servers. The game servers run on Amazon EC2 instances. The company needs a solution that can handle millions of UDP internet traffic requests each second.

Which solution will meet these requirements MOST cost-effectively?

A. Configure an Application Load Balancer with the required protocol and ports for the internet traffic. Specify the EC2 instances as the targets.
B. Configure a Gateway Load Balancer for the internet traffic. Specify the EC2 instances as the targets.
C. Configure a Network Load Balancer with the required protocol and ports for the internet traffic. Specify the EC2 instances as the targets.
D. Launch an identical set of game servers on EC2 instances in separate AWS Regions. Route internet traffic to both sets of EC2 instances.

A company has an application that uses Docker containers in its local data center. The application runs on a container host that stores persistent data in a volume on the host. The container instances use the stored persistent data.

The company wants to move the application to a fully managed service because the company does not want to manage any servers or storage infrastructure.

Which solution will meet these requirements?

A. Use Amazon Elastic Kubernetes Service (Amazon EKS) with self-managed nodes. Create an Amazon Elastic Block Store (Amazon EBS) volume attached to an Amazon EC2 instance. Use the EBS volume as a persistent volume mounted in the containers.
B. Use Amazon Elastic Container Service (Amazon ECS) with an AWS Fargate launch type. Create an Amazon Elastic File System (Amazon EFS) volume. Add the EFS volume as a persistent storage volume mounted in the containers.
C. Use Amazon Elastic Container Service (Amazon ECS) with an AWS Fargate launch type. Create an Amazon S3 bucket. Map the S3 bucket as a persistent storage volume mounted in the containers.
D. Use Amazon Elastic Container Service (Amazon ECS) with an Amazon EC2 launch type. Create an Amazon Elastic File System (Amazon EFS) volume. Add the EFS volume as a persistent storage volume mounted in the containers.

An application that is hosted on Amazon EC2 instances needs to access an Amazon S3 bucket. Traffic must not traverse the internet.

How should a solutions architect configure access to meet these requirements?

A. Create a private hosted zone by using Amazon Route 53.
B. Set up a gateway VPC endpoint for Amazon S3 in the VPC.
C. Configure the EC2 instances to use a NAT gateway to access the S3 bucket.
D. Establish an AWS Site-to-Site VPN connection between the VPC and the S3 bucket.

A company has a web application that includes an embedded NoSQL database. The application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an Amazon EC2 Auto Scaling group in a single Availability Zone.

A recent increase in traffic requires the application to be highly available and for the database to be eventually consistent.

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

A. Replace the ALB with a Network Load Balancer. Maintain the embedded NoSQL database with its replication service on the EC2 instances.
B. Replace the ALB with a Network Load Balancer. Migrate the embedded NoSQL database to Amazon DynamoDB by using AWS Database Migration Service (AWS DMS).
C. Modify the Auto Scaling group to use EC2 instances across three Availability Zones. Maintain the embedded NoSQL database with its replication service on the EC2 instances.
D. Modify the Auto Scaling group to use EC2 instances across three Availability Zones. Migrate the embedded NoSQL database to Amazon DynamoDB by using AWS Database Migration Service (AWS DMS).

A company has an on-premises volume backup solution that has reached its end of life. The company wants to use AWS as part of a new backup solution and wants to maintain local access to all the data while it is backed up on AWS. The company wants to ensure that the data backed up on AWS is automatically and securely transferred.

Which solution meets these requirements?

A. Use AWS Snowball to migrate data out of the on-premises solution to Amazon S3. Configure on-premises systems to mount the Snowball S3 endpoint to provide local access to the data.
B. Use AWS Snowball Edge to migrate data out of the on-premises solution to Amazon S3. Use the Snowball Edge file interface to provide on-premises systems with local access to the data.
C. Use AWS Storage Gateway and configure a cached volume gateway. Run the Storage Gateway software appliance on premises and configure a percentage of data to cache locally. Mount the gateway storage volumes to provide local access to the data.
D. Use AWS Storage Gateway and configure a stored volume gateway. Run the Storage Gateway software appliance on premises and map the gateway storage volumes to on-premises storage. Mount the gateway storage volumes to provide local access to the data.

A company is migrating a Linux-based web server group to AWS. The web servers must access files in a shared file store for some content. The company must not make any changes to the application.

What should a solutions architect do to meet these requirements?

A. Create an Amazon S3 Standard bucket with access to the web servers.
B. Configure an Amazon CloudFront distribution with an Amazon S3 bucket as the origin.
C. Create an Amazon Elastic File System (Amazon EFS) file system. Mount the EFS file system on all web servers.
D. Configure a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volume. Mount the EBS volume to all web servers.

A solutions architect needs to design a system to store client case files. The files are core company assets and are important. The number of files will grow over time.

The files must be simultaneously accessible from multiple application servers that run on Amazon EC2 instances. The solution must have built-in redundancy.

Which solution meets these requirements?

A. Amazon Elastic File System (Amazon EFS)
B. Amazon Elastic Block Store (Amazon EBS)
C. Amazon S3 Glacier Deep Archive
D. AWS Backup

A company wants to standardize its Amazon Elastic Block Store (Amazon EBS) volume encryption strategy. The company also wants to minimize the cost and configuration effort required to operate the volume encryption check.

Which solution will meet these requirements?

A. Write API calls to describe the EBS volumes and to confirm the EBS volumes are encrypted. Use Amazon EventBridge to schedule an AWS Lambda function to run the API calls.
B. Write API calls to describe the EBS volumes and to confirm the EBS volumes are encrypted. Run the API calls on an AWS Fargate task.
C. Create an AWS Identity and Access Management (IAM) policy that requires the use of tags on EBS volumes. Use AWS Cost Explorer to display resources that are not properly tagged. Encrypt the untagged resources manually.
D. Create an AWS Config rule for Amazon EBS to evaluate if a volume is encrypted and to flag the volume if it is not encrypted.
