Exam 9: AWS Certified Solutions Architect - Associate SAA-C02

A company is storing sensitive user information in an Amazon S3 bucket. The company wants to provide secure access to this bucket from the application tier running on Amazon EC2 instances inside a VPC. Which combination of steps should a solutions architect take to accomplish this? (Choose two.)

A company has a large Microsoft SharePoint deployment running on-premises that requires Microsoft Windows shared file storage. The company wants to migrate this workload to the AWS Cloud and is considering various storage options. The storage solution must be highly available and integrated with Active Directory for access control. Which solution will satisfy these requirements?

A monolithic application was recently migrated to AWS and is now running on a single Amazon EC2 instance. Due to application limitations, it is not possible to use automatic scaling to scale out the application. The chief technology officer (CTO) wants an automated solution to restore the EC2 instance in the unlikely event the underlying hardware fails. What would allow for automatic recovery of the EC2 instance as quickly as possible?

A company needs to share an Amazon S3 bucket with an external vendor. The bucket owner must be able to access all objects. Which action should be taken to share the S3 bucket?

A company has multiple AWS accounts for various departments. One of the departments wants to share an Amazon S3 bucket with all other department. Which solution will require the LEAST amount of effort?

An application running on an Amazon EC2 instance needs to access an Amazon DynamoDB table. Both the EC2 instance and the DynamoDB table are in the same AWS account. A solutions architect must configure the necessary permissions. Which solution will allow least privilege access to the DynamoDB table from the EC2 instance?

A company has an API-based inventory reporting application running on Amazon EC2 instances. The application stores information in an Amazon DynamoDB table. The company's distribution centers have an on-premises shipping application that calls an API to update the inventory before printing shipping labels. The company has been experiencing application interruptions several times each day, resulting in lost transactions. What should a solutions architect recommend to improve application resiliency?

A company is creating a three-tier web application consisting of a web server, an application server, and a database server. The application will track GPS coordinates of packages as they are being delivered. The application will update the database every 0-5 seconds. The tracking will need to read a fast as possible for users to check the status of their packages. Only a few packages might be tracked on some days, whereas millions of package might be tracked on other days. Tracking will need to be searchable by tracking ID customer ID and order ID. Order than 1 month no longer read to be tracked. What should a solution architect recommend to accomplish this with minimal cost of ownership?

A mobile gaming company runs application servers on Amazon EC2 instances. The servers receive updates from players every 15 minutes. The mobile game creates a JSON object of the progress made in the game since the last update, and sends the JSON object to an Application Load Balancer. As the mobile game is played, game updates are being lost. The company wants to create a durable way to get the updates in older. What should a solutions architect recommend to decouple the system?

A company has 700 TB of backup data stored in network attached storage (NAS) in its data center This backup data need to be accessible for infrequent regulatory requests and must be retained 7 years. The company has decided to migrate this backup data from its data center to AWS. The migration must be complete within 1 month. The company has 500 Mbps of dedicated bandwidth on its public internet connection available for data transfer. What should a solutions architect do to migrate and store the data at the LOWEST cost?

A company has a Microsoft Windows-based application that must be migrated to AWS. This application requires the use of a shared Windows file system attached to multiple Amazon EC2 Windows instances. What should a solutions architect do to accomplish this?

A company wants to reduce its Amazon S3 storage costs in its production environment without impacting durability or performance of the stored objects. What is the FIRST step the company should take to meet these objectives?

A company is concerned that two NAT instances in use will no longer be able to support the traffic needed for the company's application. A solutions architect wants to implement a solution that is highly available fault tolerant, and automatically scalable. What should the solutions architect recommend?

A company is reviewing a recent migration of a three-tier application to a VPC. The security team discovers that the principle of least privilege is not being applied to Amazon EC2 security group ingress and egress rules between the application tiers. What should a solutions architect do to correct this issue?

A user owns a MySQL database that is accessed by various clients who expect, at most, 100 ms latency on requests. Once a record is stored in the database, it is rarely changed. Clients only access one record at a time. Database access has been increasing exponentially due to increased client demand. The resultant load will soon exceed the capacity of the most expensive hardware available for purchase. The user wants to migrate to AWS, and is willing to change database systems. Which service would alleviate the database load issue and offer virtually unlimited scalability for the future?

A company has an Amazon EC2 instance running on a private subnet that needs to access a public websites to download patches and updates. The company does not want external websites to see the EC2 instance IP address or initiate connection to it. How can a solution architect achieve this objective?

A company requires a durable backup storage solution for its on-premises database servers while ensuring on-premises applications maintain access to these backups for quick recovery. The company will use AWS storage services as the destination for these backups. A solutions architect is designing a solution with minimal operational overhead. Which solution should the solutions architect implement?

A company runs a multi-tier web application that hosts news content. The application runs on Amazon EC2 instances behind an Application Load Balancer. The instances run in an EC2 Auto Scaling group across multiple Availability Zones and use an Amazon Aurora database. A solutions architect needs to make the application more resilient to periodic increases in request rates. Which architecture should the solutions architect implement? (Choose two.)

An application hosted on AWS is experiencing performance problems, and the application vendor wants to perform an analysis of the log file to troubleshoot further. The log file is stored on Amazon S3 and is 10 GB in size. The application owner will make the log file available to the vendor for a limited time. What is the MOST secure way to do this?

A company is preparing to deploy a data lake on AWS. A solutions architect must define the encryption strategy tor data at rest m Amazon S3/ The company's security policy states: Keys must be rotated every 90 days. Strict separation of duties between key users and key administrators must be implemented. Auditing key usage must be possible. What should the solutions architect recommend?
