Question10: A solutions architect needs to design a managed storage solution for a company's application that includes high-performance machine learning This application runs on AWS Fargate and the connected storage needs to have concurrent access to files and deliver high performance.
Which storage option should the solutions architect recommend?

Question11: A company has application running on Amazon EC2 instances in a VPC. One of the applications needs to call an Amazon S3 API to store and read objects. The company's security policies restrict any internet-bound traffic from the applications.
Which action will fulfill these requirements and maintain security?

Question12: A solutions architect is designing a new service behind Amazon API Gateway The request patterns for the service will be unpredictable and can change suddenly from 0 requests to over 500 per second The total size of the data that needs to be persisted in a backend database is currently less than 1 GB with unpredictable future growth Data can be queried using simple key-value requests Which combination of AWS services would meet these requirements'? (Select TWO )

Question13: A company is running an ecommerce application on Amazon EC2 The application consists of a stateless web tier that requires a minimum of 10 instances, and a peak of 250 instances to support the application's usage The application requires 50 instances 80% of the time Which solution should be used to minimize costs?

Question14: A company must generate sales reports at the beginning of every month. The reporting process launches 20 Amazon EC2 instances on the first of the month. The process runs for 7 days and cannot be interrupted. The company wants to minimize costs.
Which pricing model should the company choose?

Question15: A company has deployed an API in a VPC behind an internet-facing Application Load Balancer (ALB) An application that consumes the API as a client is deployed in a second account in private subnets behind a NAT gateway. When requests to the client application increase, the NAT gateway costs are higher than expected. A solutions architect has configured the ALB to be internal.
Which combination of architectural changes will reduce the NAT gateway costs'? (Select TWO )

Question16: A solutions architect is designing a system to analyze the performance of financial markets while the markets are closed The system will run a series of compute-intensive jobs for 4 hours every night The time to complete the compute jobs is expected to remain constant, and jobs cannot be interrupted once started Once completed, the system is expected to run for a minimum of 1 year Which type of Amazon EC2 instances should be used to reduce the cost of the system?

Question17: Organizers for a global event want to put daily reports online as static HTML pages The pages are expected to generate millions of views from users around the world The files are stored in an Amazon S3 bucket A solutions architect has been asked to design an efficient and effective solution Which action should the solutions architect take to accomplish this?

Question18: A company's website is using an Amazon RDS MySQL Multi-AZ DB instance for its transactional data storage.
There are other internal systems that query this DB instance to fetch data for internal batch processing. The RDS DB instance slows down significantly the internal systems fetch data. This impacts the website's read and write performance, and the users experience slow response times.
Which solution will improve the website's performance?

Question19: A company hosts a static website within an Amazon S3 bucket. A solutions architect needs to ensure that data can be recovered in case of accidental deletion.
D18912E1457D5D1DDCBD40AB3BF70D5D
Which action will accomplish this?

Question20: A financial services company has a web application that serves users in the United States and Europe The application consists of a database tier and a web server tier The database tier consists of a MySQL database hosted in us-east-1 Amazon Route 53 geoproximity routing is used to direct traffic to instances in the closest Region A performance review of the system reveals that European users are not receiving the same level of query performance as those in the United States Which changes should be made to the database tier to improve performance?

Question21: A company's website runs on Amazon EC2 instances behind an Application Load Balancer (ALB) The website has a mix of dynamic and static content Users around the globe are reporting that the website is slow Which set of actions will improve website performance for users worldwide?

Question22: A solutions architect is designing a web application that will run on Amazon EC2 instances behind an Application Load Balancer (ALB) The company strictly requires that the application be resilient against malicious internet activity and attacks, and protect against new common vulnerabilities and exposures What should the solutions architect recommend?

Question23: A company is hosting a web application on AWS using a single Amazon EC2 instance that stores user-uploaded documents in an Amazon EBS volume For better scalability and availability the company duplicated the architecture and created a second EC2 instance and EBS volume in another Availability Zone:
placing both behind an Application Load Balancer After completing this change users reported that each time they refreshed the website they could see one subset of their documents or the other but never all of the documents at the same time What should a solutions architect propose to ensure users see all of their documents at once''

Question24: A company's legacy application is currently relying on a single-instance Amazon RDS MySQL database without encryption Due to new compliance requirements, all existing and new data in this database must be encrypted How should this be accomplished?

Question25: A recently acquired company is required to buikl its own infrastructure on AWS and migrate multiple applications to the cloud within a month Each application has approximately 50 TB of data to be transferred After the migration is complete this company and its parent company will both require secure network connectivity with consistent throughput from their data centers to the applications A solutions architect must ensure one-time data migration and ongoing network connectivity Which solution will meet these requirements''
