Exam 10: AWS Certified Solutions Architect - Professional (SAP-C01)

A company has multiple lines of business (LOBs) that roll up to the parent company. The company has asked its solutions architect to develop a solution with the following requirements: Produce a single AWS invoice for all of the AWS accounts used by its LOBs. The costs for each LOB account should be broken out on the invoice. Provide the ability to restrict services and features in the LOB accounts, as defined by the company's governance policy. Each LOB account should be delegated full administrator permissions, regardless of the governance policy. Which combination of steps should the solutions architect take to meet these requirements?

A company runs its containerized batch jobs on Amazon ECS. The jobs are scheduled by submitting a container image, a task definition, and the relevant data to an Amazon S3 bucket. Container images may be unique per job. Running the jobs as quickly as possible is of utmost importance, so submitting job artifacts to the S3 bucket triggers the job to run immediately. Sometimes there may be no jobs running at all. However, jobs of any size can be submitted with no prior warning to the IT Operations team. Job definitions include CPU and memory resource requirements. What solution will allow the batch jobs to complete as quickly as possible after being scheduled?

A company has an existing on-premises three-tier web application. The Linux web servers serve content from a centralized file share on a NAS server because the content is refreshed several times a day from various sources. The existing infrastructure is not optimized and the company would like to move to AWS in order to gain the ability to scale resources up and down in response to load. On-premises and AWS resources are connected using AWS Direct Connect. How can the company migrate the web infrastructure to AWS without delaying the content refresh process?

Which of the following Amazon RDS storage types is ideal for applications with light or burst I/O requirements?

A company needs to store and process image data that will be uploaded from mobile devices using a custom mobile app. Usage peaks between 8 AM and 5 PM on weekdays, with thousands of uploads per minute. The app is rarely used at any other time. A user is notified when image processing is complete. Which combination of actions should a solutions architect take to ensure image processing can scale to handle the load? (Choose three.)

A solutions architect is building a web application that uses an Amazon RDS for PostgreSQL DB instance. The DB instance is expected to receive many more reads than writes.

A company is running a high-user-volume media-sharing application on premises. It currently hosts about 400 TB of data with millions of video files. The company is migrating this application to AWS to improve reliability and reduce costs. The Solutions Architecture team plans to store the videos in an Amazon S3 bucket and use Amazon CloudFront to distribute videos to users. The company needs to migrate this application to AWS within 10 days with the least amount of downtime possible. The company currently has 1 Gbps connectivity to the Internet with 30 percent free capacity. Which of the following solutions would enable the company to migrate the workload to AWS and meet all of the requirements?

A solutions architect needs to migrate 50 TB of NFS data to Amazon S3. The files are on several NFS file servers on corporate network. These are dense file systems containing tens of millions of small files. The system operators have configured the file interface on an AWS Snowball Edge device and are using a shell script to copy data. Developers report that copying the data to the Snowball Edge device is very slow. The solutions architect suspects this may be related to the overhead of encrypting all the small files and transporting them over the network. Which changes can be made to speed up the data transfer?

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 subsequent order 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?

An enterprise company wants to implement cost controls for all its accounts in AWS Organizations, which has full features enabled. The company has mapped organizational units (OUs) to its business units, and it wants to bill these business units for their individual AWS spending.

Which solution will meet these requirements?

Your company is getting ready to do a major public announcement of a social media site on AWS. The website is running on EC2 instances deployed across multiple Availability Zones with a Multi-AZ RDS MySQL Extra Large DB Instance.

Which are the best approaches to meet these requirements? (Choose 2 answers)

When does an AWS Data Pipeline terminate the AWS Data Pipeline-managed compute resources?

To launch the stack, the Manager uses a role with permission to use CloudFormation, EC2, and Auto Scaling APIs. The Manager wants to allow testers to launch their own environments, but does not want to grant broad permissions to each user. Which set up would achieve these goals?

A user wants to create a public subnet in VPC and launch an EC2 instance within it. The user has not selected the option to assign a public IP address while launching the instance. Which of the below mentioned statements is true with respect to this scenario?

You are responsible for a legacy web application whose server environment is approaching end of life You would like to migrate this application to AWS as quickly as possible, since the application environment currently has the following limitations: The VM's single 10GB VMDK is almost full; Me virtual network interface still uses the 10Mbps driver, which leaves your 100Mbps WAN connection completely underutilized; It is currently running on a highly customized. Windows VM within a VMware environment; You do not have me installation media; This is a mission critical application with an RTO (Recovery Time Objective) of 8 hours. RPO (Recovery Point Objective) of 1 hour. How could you best migrate this application to AWS while meeting your business continuity requirements?

A company is running a two-tier web-based application in an on-premises data center. The application user consists of a single server running a stateful application.
