A company needs to design a resilient web application to process customer orders. The web application must automatically handle increases in web traffic and application usage without affecting the customer experience or losing customer orders.
Which solution will meet these requirements?
A company runs multiple applications on Amazon EC2 instances in a VPC. Application A runs in a private subnet that has a custom route table and network ACL. Application B runs in a second private subnet in the same VPC.
The company needs to prevent Application A from sending traffic to Application B.
Which solution will meet this requirement?
A company has a VPC with multiple private subnets that host multiple applications. The applications must not be accessible to the internet. However, the applications need to access multiple AWS services. The applications must not use public IP addresses to access the AWS services.
Which solution will meet these requirements MOST cost-effectively?
A company runs an application on EC2 instances that need access to RDS credentials stored in AWS Secrets Manager.
Which solution meets this requirement?
A company has deployed a multi-tier web application to support a website. The architecture includes an Application Load Balancer (ALB) in public subnets, two Amazon Elastic Container Service (Amazon ECS) tasks in the public subnets, and a PostgreSQL cluster that runs on Amazon EC2 instances in private subnets.
The EC2 instances that host the PostgreSQL database run shell scripts that need to access an external API to retrieve product information. A solutions architect must design a solution to allow the EC2 instances to securely communicate with the external API without increasing operational overhead.
Which solution will meet these requirements?
A company wants to migrate hundreds of gigabytes of unstructured data from an on-premises location to an Amazon S3 bucket. The company has a 100-Mbps internet connection on premises. The company needs to encrypt the data in transit to the S3 bucket. The company will store new data directly in Amazon S3.
A developer needs to export the contents of several Amazon DynamoDB tables into Amazon S3 buckets to comply with company data regulations. The developer uses the AWS CLI to runcommands to export from each table to the proper S3 bucket. The developer sets up AWS credentials correctly and grants resources appropriate permissions. However, the exports of some tables fail.
What should the developer do to resolve this issue?
A media company stores customer-uploaded videos in an Amazon S3 bucket with the Standard storage class. The company wants to create an S3 Lifecycle configuration. The company will set the maximum retention time to 7 days. However, the configuration must delete any video that is more than 1 TB in size after 48 hours.
A company hosts an application on AWS that stores files that users need to access. The application uses two Amazon EC2 instances. One instance is in Availability Zone A, and the second instance is in Availability Zone B. Both instances use Amazon Elastic Block Store (Amazon EBS) volumes. Users must be able to access the files at any time without delay. Users report that the two instances occasionally contain different versions of the same file. Users occasionally receive HTTP 404 errors when they try to download files. The company must address the customer issues. The company cannot make changes to the application code. Which solution will meet these requirements in the MOST operationally efficient way?
A company has an application that serves clients that are deployed in more than 20.000 retail storefront locations around the world. The application consists of backend web services that are exposed over HTTPS on port 443 The application is hosted on Amazon EC2 Instances behind an Application Load Balancer (ALB). The retail locations communicate with the web application over the public internet. The company allows each retail location to register the IP address that the retail location has been allocated by its local ISP.
The company's security team recommends to increase the security of the application endpoint by restricting access to only the IP addresses registered by the retail locations.
What should a solutions architect do to meet these requirements?
A large financial services company uses Amazon ElastiCache (Redis OSS) for its new application that has a global user base. A solutions architect must develop a caching solution that will be available across AWS Regions and include low-latency replication and failover capabilities for disaster recovery (DR). The company's security team requires the encryption of cross-Region data transfers.
Which solution meets these requirements with the LEAST amount of operational effort?
A global ecommerce company runs its critical workloads on AWS. The workloads use an Amazon RDS for PostgreSQL DB instance that is configured for a Multi-AZ deployment.
Customers have reported application timeouts when the company undergoes database failovers. The company needs a resilient solution to reduce failover time
Which solution will meet these requirements?
A solutions architect is provisioning an Amazon Elastic File System (Amazon EFS) file system to provide shared storage across multiple Amazon EC2 instances. The instances all exist in the same VPC across multiple Availability Zones. There are two instances in each Availability Zone. The solutions architect must make the file system accessible to each instance with the lowest possible latency.
Which solution will meet these requirements?
A company has an application that runs on an Amazon Elastic Kubernetes Service (Amazon EKS) cluster on Amazon EC2 instances. The application has a U1 that uses Amazon DynamoDB and data services that use Amazon S3 as part of the application deployment.
The company must ensure that the EKS Pods for the U1 can access only Amazon DynamoDB and that the EKS Pods for the data services can access only Amazon S3. The company uses AWS Identity and Access Management |IAM).
Which solution meets these requirements?
A company is building a serverless application that processes large volumes of data from a mobile app. The application uses an AWS Lambda function to process the data and store the data in an Amazon DynamoDB table.
The company needs to ensure that the application can recover from failures and continue processing data without losing any records.
