A company built an ecommerce website on AWS using a three-tier web architecture. The application is Java-based and composed of an Amazon CloudFront distribution, an Apache web server layer of Amazon EC2 instances in an Auto Scaling group, and a backend Amazon Aurora MySQL database.
Last month, during a promotional sales event, users reported errors and timeouts while adding items to their shopping carts. The operations team recovered the logs created by the web servers and reviewed Aurora DB cluster performance metrics. Some of the web servers were terminated before logs could be collected and the Aurora metrics were not sufficient for query performance analysis.
Which combination of steps must the solutions architect take to improve application performance visibility during peak traffic events? (Choose three.)
A company is using AWS CodePipeline for the CI/CD of an application to an Amazon EC2 Auto Scaling group. All AWS resources are defined in AWS
CloudFormation templates. The application artifacts are stored in an Amazon S3 bucket and deployed to the Auto Scaling group using instance user data scripts.
As the application has become more complex, recent resource changes in the CloudFormation templates have caused unplanned downtime.
How should a solutions architect improve the CI/CD pipeline to reduce the likelihood that changes in the templates will cause downtime?
A company wants to use Amazon Workspaces in combination with thin client devices to replace aging desktops. Employees use the desktops to access applications that work with clinical trial data. Corporate security policy states that access to the applications must be restricted to only company branch office locations. The company is considering adding an additional branch office in the next 6 months.
Which solution meets these requirements with the MOST operational efficiency?
A solutions architect is reviewing an application's resilience before launch. The application runs on an Amazon EC2 instance that is deployed in a private subnet of a VPC.
The EC2 instance is provisioned by an Auto Scaling group that has a minimum capacity of I and a maximum capacity of I. The application stores data on an Amazon RDS for MySQL DB instance. The VPC has subnets configured in three Availability Zones and is configured with a single NAT gateway.
The solutions architect needs to recommend a solution to ensure that the application will operate across multiple Availability Zones.
Which solution will meet this requirement?
A company needs to migrate its on-premises database fleet to Amazon RDS. The company is currently using a mixture of Microsoft SQL Server, and Oracle databases. Some of the databases have custom schemas and stored procedures.
Which combination of steps should the company take for the migration? (Select TWO.)
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 global ecommerce company has many data centers worldwide. The company needs scalable cloud storage for legacy file applications. Requirements:
Must support iSCSI access from on-premises servers.
Must support point-in-time snapshots via AWS Backup.
Must retain low-latency access to frequently accessed data.Which solution will meet these requirements?
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.
Which solution will meet these requirements?
A company has separate AWS accounts for each of its departments. The accounts are in OUs that are in an organization in AWS Organizations. The IT department manages a private certificate authority (CA) by using AWS Private Certificate Authority in its account.
The company needs a solution to allow developer teams in the other departmental accounts to access the private CA to issue certificates for their applications. The solution must maintain appropriate security boundaries between accounts.
Which solution will meet these requirements?
An online retail company is migrating its legacy on-premises .NET application to AWS. The application runs on load-balanced frontend web servers, load-balanced application servers, and a Microsoft SQL Server database.
The company wants to use AWS managed services where possible and does not want to rewrite the application. A solutions architect needs to implement a solution to resolve scaling issues and minimize licensing costs as the application scales.
Which solution will meet these requirements MOST cost-effectively?
A company's factory and automaton applications are running in a single VPC More than 23 applications run on a combination of Amazon EC2, Amazon Elastic Container Service (Amazon ECS), are Amazon RDS.
The company has software engineers spread across three teams. One of the three teams owns each application, and each team is responsible for the cost and performance of all of its applications.Team resources have tags that represent their application and team. The learns use IAH access for daily activities.
The company needs to determine which costs on the monthly AWS bill are attributable to each application or team. The company also must be able to create reports to compare costs item the last 12 months and to help forecast costs tor the next 12 months. A solution architect must recommend an AWS Billing and Cost Management solution that provides these cost reports.
Which combination of actions will meet these requirement? Select THREE.)
A startup company recently migrated a large ecommerce website to AWS The website has experienced a 70% increase in sates Software engineers are using a private GitHub repository to manage code The DevOps team is using Jenkins for builds and unit testing The engineers need to receive notifications for bad builds and zero downtime during deployments The engineers also need to ensure any changes to production are seamless for users and can be rolled back in the event of a major issue
The software engineers have decided to use AWS CodePipeline to manage their build and deployment process
Which solution will meet these requirements'?
A company has a solution that analyzes weather data from thousands of weather stations. The weather stations send the data over an Amazon API Gateway REST API that has an AWS Lambda function integration. The Lambda function calls a third-party service for data pre-processing. The third-party service gets overloadedand fails the pre-processing, causing a loss of data.
A solutions architect must improve the resiliency of the solution. The solutions architect must ensure that no data is lost and that data can be processed later if failures occur.
What should the solutions architect do to meet these requirements?
A company is rearchitecting its applications to run on AWS. The company's infrastructure includes multiple Amazon EC2 instances. The company's development team needs different levels of access. The company wants to implement a policy that requires all Windows EC2 instances to be joined to an Active Directory domain on AWS. The company also wants to Implement enhanced security processes such as multi-factor authentication (MFA). The company wants to use managed AWS services wherever possible.
Which solution will meet these requirements?
A company is deploying a third-party firewall appliance solution from AWS Marketplace to monitor and protect traffic that leaves the company's AWS environments. The company wants to deploy this appliance into a shared services VPC and route all outbound internet-bound traffic through the appliances.
A solutions architect needs to recommend a deployment method that prioritizes reliability and minimizes failover time between firewall appliances within a single AWS Region. The company has set up routing from the shared services VPC to other VPCs.
Which steps should the solutions architect recommend to meet these requirements? (Select THREE.)
