A company has a web application that runs on premises. The application experiences latency issues during peak hours. The latency issues occur twice each month. At the start of a latency issue, the application's CPU utilization immediately increases to 10 times its normal amount.
The company wants to migrate the application to AWS to improve latency. The company also wants to scale the application automatically when application demand increases. The company will use AWS Elastic Beanstalk for application deployment.
Which solution will meet these requirements?
A. Configure an Elastic Beanstalk environment to use burstable performance instances in unlimited mode. Configure the environment to scale based on requests.A company moved its on-premises PostgreSQL database to an Amazon RDS for PostgreSQL DB instance. The company successfully launched a new product. The workload on the database has increased. The company wants to accommodate the larger workload without adding infrastructure.
Which solution will meet these requirements MOST cost-effectively?
A. Buy reserved DB instances for the total workload. Make the Amazon RDS for PostgreSQL DB instance larger.A company has a small Python application that processes JSON documents and outputs the results to an on-premises SQL database. The application runs thousands of times each day. The company wants to move the application to the AWS Cloud. The company needs a highly available solution that maximizes scalability and minimizes operational overhead.
Which solution will meet these requirements?
A. Place the JSON documents in an Amazon S3 bucket. Run the Python code on multiple Amazon EC2 instances to process the documents. Store the results in an Amazon Aurora DB cluster.An ecommerce company is building a distributed application that involves several serverless functions and AWS services to complete order-processing tasks. These tasks require manual approvals as part of the workflow. A solutions architect needs to design an architecture for the order-processing application. The solution must be able to combine multiple AWS Lambda functions into responsive serverless applications.
The solution also must orchestrate data and services that run on Amazon EC2 instances, containers, or on-premises servers.
Which solution will meet these requirements with the LEAST operational overhead?
A. Use AWS Step Functions to build the application.A solutions architect is designing a user authentication solution for a company. The solution must invoke two-factor authentication for users that log in from inconsistent geographical locations, IP addresses, or devices. The solution must also be able to scale up to accommodate millions of users.
Which solution will meet these requirements?
A. Configure Amazon Cognito user pools for user authentication. Enable the risk-based adaptive authentication feature with multifactor authentication (MFA).A company uses an Amazon EC2 instance to handle requests for a public web application. The application routes traffic to multiple application pages by using URL paths.
The company begins to experience large surges of traffic at unpredictable times. The traffic surges cause the web application to experience issues and to occasionally become unavailable. The company needs to make the web application more scalable to handle sudden increases in traffic.
Which solution will meet this requirement?
A. Create an Amazon Machine Image (AMI) of the web application instance. Use the AMI to create an Auto Scaling group of EC2 instances that has a minimum capacity of two. Create an Application Load Balancer. Set the Auto Scaling group as the target group.A company is setting up a development environment on AWS for a team of developers. The team needs to access multiple Amazon S3 buckets to store project data. The team also needs to use Amazon EC2 to run development instances.
The company needs to ensure that the developers have access only to specific Amazon S3 buckets and EC2 instances. Access permissions must be assigned according to each developer's role on the team. The company wants to minimize the use of permanent credentials and to ensure access is securely managed according to the principle of least privilege.
Which solution will meet these requirements?
A. Create IAM roles that have administrative-level permissions for Amazon S3 and Amazon EC2. Require developers to sign in by using Amazon Cognito to access Amazon S3 and Amazon EC2.A company runs an ecommerce application on AWS. Amazon EC2 instances process purchases and store the purchase details in an Amazon Aurora PostgreSQL DB cluster. Customers are experiencing application timeouts during times of peak usage. A solutions architect needs to rearchitect the application so that the application can scale to meet peak usage demands.
Which combination of actions will meet these requirements MOST cost-effectively? (Choose two.)
A. Configure an Auto Scaling group of new EC2 instances to retry the purchases until the processing is complete. Update the applications to connect to the DB cluster by using Amazon RDS Proxy.A company has a three-tier web application that processes orders from customers. The web tier consists of Amazon EC2 instances behind an Application Load Balancer. The processing tier consists of EC2 instances. The company decoupled the web tier and processing tier by using Amazon Simple Queue Service (Amazon SQS). The storage layer uses Amazon DynamoDB. At peak times, some users report order processing delays and halls. The company has noticed that during these delays, the EC2 instances are running at 100% CPU usage, and the SQS queue fills up. The peak times are variable and unpredictable.
The company needs to improve the performance of the application.
Which solution will meet these requirements?
A. Use scheduled scaling for Amazon EC2 Auto Scaling to scale out the processing tier instances for the duration of peak usage times. Use the CPU Utilization metric to determine when to scale.A company is building an Amazon Elastic Kubernetes Service (Amazon EKS) cluster for its workloads. All secrets that are stored in Amazon EKS must be encrypted in the Kubernetes etcd key-value store.
Which solution will meet these requirements?
A. Create a new AWS Key Management Service (AWS KMS) key. Use AWS Secrets Manager to manage, rotate, and store all secrets in Amazon EKS.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
