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?
A company is migrating an application from on-premises infrastructure to the AWS Cloud. During migration design meetings, the company expressed concerns about the availability and recovery options for its legacy Windows file server. The file server contains sensitive business-critical data that cannot be recreated in the event of data corruption or data loss. According to compliance requirements, the data must not travel across the public internet. The company wants to move to AWS managed services where possible.
The company decides to store the data in an Amazon FSx for Windows File Server file system. A solutions architect must design a solution that copies the data to another AWS Region for disaster recovery (DR) purposes.
Which solution will meet these requirements?
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 is moving a business-critical, multi-tier application to AWS. The architecture consists of a desktop client application and server infrastructure. The server infrastructure resides in an on-premises data center that frequently fails to maintain the application uptime SLA of 99.95%. A solutions architect must re-architect the application to ensure that it can meet or exceed the SLA.
The application contains a PostgreSQL database running on a single virtual machine. The business logic and presentation layers are load balanced between multiple virtual machines. Remote users complain about slow load times while using this latency-sensitive application.
Which of the following will meet the availability requirements with little change to the application while improving user experience and minimizing costs?
A company uses an on-premises data analytics platform. The system is highly available in a fully redundant configuration across 12 servers in the company ' s data center.
The system runs scheduled jobs, both hourly and daily, in addition to one-time requests from users.Scheduled jobs can take between 20 minutes and 2 hours to finish running and have tight SLAs. The scheduled jobs account for 65% of the system usage. User jobs typically finish running in less than 5 minutes and have no SLA. The user jobs account for 35% of system usage. During system failures, scheduled jobs must continue to meet SLAs. However, user jobs can be delayed.
A solutions architect needs to move the system to Amazon EC2 instances and adopt a consumption-based model to reduce costs with no long-term commitments. The solution must maintain high availability and must not affect the SLAs.
Which solution will meet these requirements MOST cost-effectively?
A company operates a proxy server on a fleet of Amazon EC2 instances. Partners in different countries use the proxy server to test the company ' s functionality. The EC2 instances are running in a VPC. and the instances have access to the internet.
The company ' s security policy requires that partners can access resources only from domains that the company owns.
Which solution will meet these requirements?
A company is migrating a legacy application from an on-premises data center to AWS. The application consists of a single application server and a Microsoft SQL
Server database server. Each server is deployed on a VMware VM that consumes 500 TB of data across multiple attached volumes.
The company has established a 10 Gbps AWS Direct Connect connection from the closest AWS Region to its on-premises data center. The Direct Connect connection is not currently in use by other services.
Which combination of steps should a solutions architect take to migrate the application with the LEAST amount of downtime? (Choose two.)
A company has an on-premises Microsoft SOL Server database that writes a nightly 200 GB export to a local drive. The company wants to move the backups to more robust cloud storage on Amazon S3. The company has set up a 10 Gbps AWS Direct Connect connection between the on-premises data center and AWS.
Which solution meets these requirements MOST cost-effectively?
A company has implemented an ordering system using an event-driven architecture. During initial testing, the system stopped processing orders. Further log analysis revealed that one order message in an Amazon Simple Queue Service (Amazon SQS) standard queue was causing an error on the backend and blocking all subsequentorder messages The visibility timeout of the queue is set to 30 seconds, and the backend processing timeout is set to 10 seconds. A solutions architect needs to analyze faulty order messages and ensure that the system continues to process subsequent messages.
Which step should the solutions architect take to meet these requirements?
A company has an application that uses an Amazon Aurora PostgreSQL DB cluster for the application ' s database. The DB cluster contains one small primary instance and three larger replica instances. The application runs on an AWS Lambda function. The application makes many short-lived connections to the database ' s replica instances to perform read-only operations.
During periods of high traffic, the application becomes unreliable and the database reports that too many connections are being established. The frequency of high-traffic periods is unpredictable.
Which solution will improve the reliability of the application?
A company operates a data analytics platform that uses Amazon S3 to store petabytes of customer data. The platform stores data in multiple S3 buckets across four AWS Regions. The company has configured S3 Cross-Region Replication and uses several S3 prefixes across the S3 buckets.
The company wants to analyze and visualize trends and replication metrics for its S3 storage, including for specific prefixes, over a 12-month period.
Which solution will meet these requirements with the LEAST operational overhead?
A company has deployed applications to thousands of Amazon EC2 instances in an AWS account. A security audit discovers that several unencrypted Amazon EBS volumes are attached to the EC2 instances. The company ' s security policy requires the EBS volumes to be encrypted.
The company needs to implement an automated solution to encrypt the EBS volumes. The solution also must prevent development teams from creating unencrypted EBS volumes.
Which solution will meet these requirements?
A company uses an AWS CodeCommit repository The company must store a backup copy of the data that is in the repository in a second AWS Region
Which solution will meet these requirements?
Question:
A company runs production workloads on EC2 On-Demand Instances and RDS for PostgreSQL. They want to reduce costs without compromising availability or capacity.
A company is deploying a third-party web application on AWS. The application is packaged as a Docker image. The company has deployed the Docker image as an AWS
Fargate service in Amazon Elastic Container Service (Amazon ECS). An Application Load Balancer (ALB) directs traffic to the application.
The company needs to give only a specific list of users the ability to access the application from the internet. The company cannot change the application and cannot integrate the application with an identity provider. All users must be authenticated through multi-factor authentication (MFA).
