A university research laboratory needs to migrate 30 TB of data from an on-premises Windows file server to Amazon FSx for Windows File Server. The laboratory has a 1 Gbps network link that many other departments in the university share.

The laboratory wants to implement a data migration service that will maximize the performance of the data transfer. However, the laboratory needs to be able to control the amount of bandwidth that the service uses to minimize the impact on other departments. The data migration must take place within the next 5 days.

Which AWS solution will meet these requirements?

A. AWS Snowcone
B. Amazon FSx File Gateway
C. AWS DataSync
D. AWS Transfer Family

A company wants to deploy its containerized application workloads to a VPC across three Availability Zones. The company needs a solution that is highly available across Availability Zones. The solution must require minimal changes to the application.

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

A. Use Amazon Elastic Container Service (Amazon ECS). Configure Amazon ECS Service Auto Scaling to use target tracking scaling. Set the minimum capacity to 3. Set the task placement strategy type to spread with an Availability Zone attribute.
B. Use Amazon Elastic Kubernetes Service (Amazon EKS) self-managed nodes. Configure Application Auto Scaling to use target tracking scaling. Set the minimum capacity to 3.
C. Use Amazon EC2 Reserved Instances. Launch three EC2 instances in a spread placement group. Configure an Auto Scaling group to use target tracking scaling. Set the minimum capacity to 3.
D. Use an AWS Lambda function. Configure the Lambda function to connect to a VPC. Configure Application Auto Scaling to use Lambda as a scalable target. Set the minimum capacity to 3.

An ecommerce company is preparing to deploy a web application on AWS to ensure continuous service for customers. The architecture includes a web application that the company hosts on Amazon EC2 instances, a relational database in Amazon RDS, and static assets that the company stores in Amazon S3.

The company wants to design a robust and resilient architecture for the application.

Which solution will meet these requirements?

A. Deploy Amazon EC2 instances in a single Availability Zone. Deploy an RDS DB instance in the same Availability Zone. Use Amazon S3 with versioning enabled to store static assets.
B. Deploy Amazon EC2 instances in an Auto Scaling group across multiple Availability Zones. Deploy a Multi-AZ RDS DB instance. Use Amazon CloudFront to distribute static assets.
C. Deploy Amazon EC2 instances in a single Availability Zone. Deploy an RDS DB instance in a second Availability Zone for cross-AZ redundancy. Serve static assets directly from the EC2 instances.
D. Use AWS Lambda functions to serve the web application. Use Amazon Aurora Serverless v2 for the database. Store static assets in Amazon Elastic File System (Amazon EFS) One Zone-Infrequent Access (One Zone-IA).

A company has multiple Microsoft Windows SMB file servers and Linux NFS file servers for file sharing in an on-premises environment. As part of the company's AWS migration plan, the company wants to consolidate the file servers in the AWS Cloud.

The company needs a managed AWS storage service that supports both NFS and SMB access. The solution must be able to share between protocols. The solution must have redundancy at the Availability Zone level.

Which solution will meet these requirements?

A. Use Amazon FSx for NetApp ONTAP for storage. Configure multi-protocol access.
B. Create two Amazon EC2 instances. Use one EC2 instance for Windows SMB file server access and one EC2 instance for Linux NFS file server access.
C. Use Amazon FSx for NetApp ONTAP for SMB access. Use Amazon FSx for Lustre for NFS access.
D. Use Amazon S3 storage. Access Amazon S3 through an Amazon S3 File Gateway.

A company hosts a video streaming web application in a VPC. The company uses a Network Load Balancer (NLB) to handle TCP traffic for real-time data processing. There have been unauthorized attempts to access the application.

The company wants to improve application security with minimal architectural change to prevent unauthorized attempts to access the application.

Which solution will meet these requirements?

A. Implement a series of AWS WAF rules directly on the NLB to filter out unauthorized traffic.
B. Recreate the NLB with a security group to allow only trusted IP addresses.
C. Deploy a second NLB in parallel with the existing NLB configured with a strict IP address allow list.
D. Use AWS Shield Advanced to provide enhanced DDoS protection and prevent unauthorized access attempts.

A company is designing an application on AWS that processes sensitive data. The application stores and processes financial data for multiple customers.

To meet compliance requirements, the data for each customer must be encrypted separately at rest by using a secure, centralized key management solution. The company wants to use AWS Key Management Service (AWS KMS) to implement encryption.

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

A. Generate a unique encryption key for each customer. Store the keys in an Amazon S3 bucket. Enable server-side encryption.
B. Deploy a hardware security appliance in the AWS environment that securely stores customer-provided encryption keys. Integrate the security appliance with AWS KMS to encrypt the sensitive data in the application.
C. Create a single AWS KMS key to encrypt all sensitive data across the application.
D. Create separate AWS KMS keys for each customer's data that have granular access control and logging enabled.

A company recently performed a lift and shift migration of its on-premises Oracle database workload to run on an Amazon EC2 memory optimized Linux instance. The EC2 Linux instance uses a 1 TB Provisioned IOPS SSD (io1) EBS volume with 64,000 IOPS.

The database storage performance after the migration is slower than the performance of the on-premises database.

Which solution will improve storage performance?

A. Add more Provisioned IOPS SSD (io1) EBS volumes. Use OS commands to create a Logical Volume Management (LVM) stripe.
B. Increase the Provisioned IOPS SSD (io1) EBS volume to more than 64,000 IOPS.
C. Increase the size of the Provisioned IOPS SSD (io1) EBS volume to 2 TB.
D. Change the EC2 Linux instance to a storage optimized instance type. Do not change the Provisioned IOPS SSD (io1) EBS volume.

A company hosts an application on Amazon EC2 instances that run in a single Availability Zone. The application is accessible by using the transport layer of the Open Systems Interconnection (OSI) model. The company needs the application architecture to have high availability.

Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)

A. Configure new EC2 instances in a different Availability Zone. Use Amazon Route 53 to route traffic to all instances.
