A company hosts a software as a service (SaaS) solution on AWS. The solution has an Amazon API Gateway API that serves an HTTPS endpoint. The API uses AWS Lambda functions for compute. The Lambda functions store data in an Amazon Aurora Serverless VI database.
The company used the AWS Serverless Application Model (AWS SAM) to deploy the solution. The solution extends across multiple Availability Zones and has nodisaster recovery (DR) plan.
A solutions architect must design a DR strategy that can recover the solution in another AWS Region. The solution has an R TO of 5 minutes and an RPO of 1 minute.
What should the solutions architect do to meet these requirements?
Question:
A company is modernizing a legacy.NET Frameworkapplication backed by SQL Server. Requirements:
Containerize into microservices.
Control OS patches and storage.
Add load balancing.
Ensure high availability.Which solution meets all of these with minimal refactoring?
A company gives users the ability to upload images from a custom application. The upload process invokes an AWS Lambda function that processes and stores the image in an Amazon S3 bucket. The application invokes the Lambda function by using a specific function version ARN.
The Lambda function accepts image processing parameters by using environment variables. The company often adjusts the environment variables of the Lambda function to achieve optimal image processing output. The company tests different parameters and publishes a new function version with the updated environment variables after validating results. This update process also requires frequent changes to the custom application to invoke the new function version ARN. These changes cause interruptions for users.
A solutions architect needs to simplify this process to minimize disruption to users.
Which solution will meet these requirements with the LEAST operational overhead?
A solutions architect needs to define a reference architecture for a solution for three-tier applications with web. application, and NoSQL data layers. The reference architecture must meet the following requirements:
•High availability within an AWS Region
•Able to fail over in 1 minute to another AWS Region for disaster recovery
•Provide the most efficient solution while minimizing the impact on the user experience
Which combination of steps will meet these requirements? (Select THREE.)
A company needs to implement disaster recovery for a critical application that runs in a single AWS Region. The application's users interact with a web frontend that is hosted on Amazon EC2 Instances behind an Application Load Balancer (ALB). The application writes to an Amazon RD5 tor MySQL DB instance. The application also outputs processed documents that are stored in an Amazon S3 bucket
The company's finance team directly queries the database to run reports. During busy periods, these queries consume resources and negatively affect application performance.
A solutions architect must design a solution that will provide resiliency during a disaster. The solution must minimize data loss and must resolve the performance problems that result from the finance team's queries.
Which solution will meet these requirements?
A company is running an application in the AWS Cloud. The application runs on containers in an Amazon Elastic Container Service (Amazon ECS) cluster. The ECS tasks use the Fargate launch type. The application's data is relational and is stored in Amazon Aurora MySQL. To meet regulatory requirements, the application must be able to recover to a separate AWS Region in the event of an application failure. In case of a failure, no data can be lost. Which solution will meet these requirements with the LEAST amount of operational overhead?
A company needs to gather data from an experiment in a remote location that does not have internet connectivity. During the experiment, sensors that are connected to a total network will generate 6 TB of data in a preprimary formal over the course of 1 week. The sensors can be configured to upload their data files to an FTP server periodically, but the sensors do not have their own FTP server. The sensors also do not support other protocols. The company needs to collect the data centrally and move lie data to object storage in the AWS Cloud as soon. as possible after the experiment.
Which solution will meet these requirements?
A team collects and routes behavioral data for an entire company The company runs a Multi-AZ VPC environment with public subnets, private subnets, and in internet gateway Each public subnet also contains a NAT gateway Most of the company's applications read from and write to Amazon Kinesis Data Streams. Most of the workloads am in private subnets.
A solutions architect must review the infrastructure The solutions architect needs to reduce costs and maintain the function of the applications The solutions architect uses Cost Explorer and notices that the cost in the EC2-Other category is consistently high A further review shows that NatGateway-Bytes charges are increasing the cost in the EC2-Other category.
What should the solutions architect do to meet these requirements?
A company collects air quality data from sensors. The company plans to use the MQTT protocol to send the data to AWS IoT Core. The company will process the data and then will store the data in an Amazon Aurora database.
During periods of low air quality, sensors will send data more frequently. The company must buffer the data during these periods to make sure that no data is lost before the data is processed and stored.
Which solution will meet these requirements?
A company is building a serverless application that runs on an AWS Lambda function that is attached to a VPC. The company needs to integrate the application with a new service from an external provider. The external provider supports only requests that come from public IPv4 addresses that are in an allow list.
The company must provide a single public IP address to the external provider before the application can start using the new service.
Which solution will give the application the ability to access the new service?
Question:
How can a company patch EC2 instanceswithout internet access, using apatch source in another account, while accessing Systems Manager and S3?
A company in the United States (US) has acquired a company in Europe. Both companies use the AWS Cloud. The US company has built a new application with a microservices architecture. The US company is hosting the application across five VPCs in the us-east-2 Region. The application must be able to access resources in one VPC in the eu-west-1 Region. However, the application must not be able to access any other VPCs. The VPCs in both Regions have no overlapping CIDR ranges. All accounts are already consolidated in one organization in AWS Organizations. Which solution will meet these requirements MOST cost-effectively?
A company has several Amazon DynamoDB tables in an AWS Region. Each table has more than 100,000 records and was created with default table settings.
To reduce costs, the company needs to identify unused tables. However, the company must maintain the availability and current performance capability of the tables in case the company must use the tables in the future.
Which combination of steps will meet these requirements? (Select THREE.)
A company is planning to migrate its on-premises VMware cluster of 120 VMS to AWS. The VMS have many different operating systems and many custom software
packages installed. The company also has an on-premises NFS server that is 10 TB in size. The company has set up a 10 GbpsAWS Direct Connect connection to AWS for the migration
Which solution will complete the migration to AWS in the LEAST amount of time?
A company runs an ecommerce website on Amazon ECS behind an Application Load Balancer (ALB). The company stores the container images in Amazon ECR. The website stores data in an Amazon Aurora MySQL DB cluster. The company uses an Amazon S3 bucket to store backup data.
The company needs to prevent data tampering. The website domain is registered with Amazon Route 53. The company wants to recreate the setup in a second AWS Region with an RPO of 5 minutes and an RTO of 15 minutes. The company has created an ALB in the second Region.
