A company is building a software-as-a-service (SaaS) solution on AWS. The company has deployed an Amazon API Gateway REST API with AWS Lambda integration in multiple AWS Regions and in the same production account.
The company offers tiered pricing that gives customers the ability to pay for the capacity to make a certain number of API calls per second. The premium tier offers up to 3,000 calls per second, and customers are identified by a unique API key. Several premium tier customers in various Regions report that they receive error responses of 429 Too Many Requests from multiple API methods during peak usage hours. Logs indicate that the Lambda function is never invoked.
What could be the cause of the error messages for these customers?
A. The Lambda function reached its concurrency limit.
B. The Lambda function its Region limit for concurrency.
C. The company reached its API Gateway account limit for calls per second.
D. The company reached its API Gateway default per-method limit for calls per second.
A company is migrating some of its applications to AWS. The company wants to migrate and modernize the applications quickly after it finalizes networking and security strategies. The company has set up an AWS Direct Connection connection in a central network account.
The company expects to have hundreds of AWS accounts and VPCs in the near future. The corporate network must be able to access the resources on AWS seamlessly and also must be able to communicate with all the VPCs. The company also wants to route its cloud resources to the internet through its on-premises data center.
Which combination of steps will meet these requirements? (Choose three.)
A. Create a Direct Connect gateway in the central account. In each of the accounts, create an association proposal by using the Direct Connect gateway and the account ID for every virtual private gateway.
B. Create a Direct Connect gateway and a transit gateway in the central network account. Attach the transit gateway to the Direct Connect gateway by using a transit VIF.
C. Provision an internet gateway. Attach the internet gateway to subnets. Allow internet traffic through the gateway.
D. Share the transit gateway with other accounts. Attach VPCs to the transit gateway.
E. Provision VPC peering as necessary.
F. Provision only private subnets. Open the necessary route on the transit gateway and customer gateway to allow outbound internet traffic from AWS to flow through NAT services that run in the data center.
A hedge fund company is developing a new web application to handle trades. Traders around the world will use the application. The application will handle hundreds of thousands of transactions, especially during overlapping work hours between Europe and the United States.
According to the company's disaster recovery plan, the data that is generated must be replicated to a second AWS Region. Each transaction item will be less than 100 KB in size. The company wants to simplify the CI/CD pipeline as much as possible.
Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)
A. Deploy the application in multiple Regions. Use Amazon Route 53 latency-based routing to route users
to the nearest deployment.
B. Provision an Amazon Aurora global database to persist data. Use Amazon ElastiCache to improve response time.
C. Provision an Amazon CloudFront domain with the website as an origin. Restrict access to geographies where the usage is expected.
D. Provision an Amazon DynamoDB global table. Use DynamoDB Accelerator (DAX) to improve response time.
E. Provision an Amazon Aurora multi-master cluster to persist data. Use Amazon ElastiCache to improve response time.
A company has several AWS accounts. A development team is building an automation framework for cloud governance and remediation processes. The automation framework uses AWS Lambda functions in a centralized account. A solutions architect must implement a least privilege permissions policy that allows the Lambda functions to run in each of the company's AWS accounts. Which combination of steps will meet these requirements? (Choose two.)
A. In the centralized account, create an IAM role that has the Lambda service as a trusted entity. Add an inline policy to assume the roles of the other AWS accounts.
B. In the other AWS accounts, create an IAM role that has minimal permissions. Add the centralized account's Lambda IAM role as a trusted entity.
C. In the centralized account, create an IAM role that has roles of the other accounts as trusted entities. Provide minimal permissions.
D. In the other AWS accounts, create an IAM role that has permissions to assume the role of the centralized account. Add the Lambda service as a trusted entity.
E. In the other AWS accounts, create an IAM role that has minimal permissions. Add the Lambda service as a trusted entity.
A video processing company wants to build a machine learning (ML) model by using 600 TB of compressed data that is stored as thousands of files in the company's on-premises network attached storage system. The company does not have the necessary compute resources on premises for ML experiments and wants to use AWS.
The company needs to complete the data transfer to AWS within 3 weeks. The data transfer will be a onetime transfer. The data must be encrypted in transit. The measured upload speed of the company's internet connection is 100 Mbps, and multiple departments share the connection.
Which solution will meet these requirements MOST cost-effectively?
A. Order several AWS Snowball Edge Storage Optimized devices by using the AWS Management Console. Configure the devices with a destination S3 bucket. Copy the data to the devices. Ship the devices back to AWS.
B. Set up a 10 Gbps AWS Direct Connect connection between the company location and the nearest AWS Region. Transfer the data over a VPN connection into the Region to store the data in Amazon S3.
C. Create a VPN connection between the on-premises network storage and the nearest AWS Region. Transfer the data over the VPN connection.

A company wants to use Amazon S3 to back up its on-premises file storage solution. The company's on-premises file storage solution supports NFS, and the company wants its new solution to support NFS. The company wants to archive the backup files after 5 days. If the company needs archived files for disaster recovery, the company is willing to wait a few days for the retrieval of those files.
Which solution meets these requirements MOST cost-effectively?
A. Deploy an AWS Storage Gateway files gateway that is associated with an S3 bucket. Move the files from the on-premises file storage solution to the file gateway. Create an S3 Lifecycle rule to move the file to S3 Standard-Infrequent Access (S3 Standard-IA) after 5 days.
B. Deploy an AWS Storage Gateway volume gateway that is associated with an S3 bucket. Move the files from the on-premises file storage solution to the volume gateway. Create an S3 Lifecycle rule to move the files to S3 Glacier Deep Archive after 5 days.
C. Deploy an AWS Storage Gateway tape gateway that is associated with an S3 bucket. Move the files from the on-premises file storage solution to the tape gateway. Create an S3 Lifecycle rule to move the files to S3 Standard-Infrequent Access (S3 Standard-IA) after 5 days.
D. Deploy an AWS Storage Gateway file gateway that is associated with an S3 bucket. Move the files from the on-premises file storage solution to the file gateway. Create an S3 Lifecycle rule to move the files to S3 Glacier Deep Archive after 5 days.
