AWS Certified Solutions Architect - Associate (SAA-001) v1.0

A company is evaluating Amazon S3 as a data storage solution for their daily analyst reports. The company has implemented stringent requirements concerning the security of the data at rest. Specifically, the CISO asked for the use of envelope encryption with separate permissions for the use of an envelope key, automated rotation of the encryption keys, and visibility into when an encryption key was used and by whom.
Which steps should a Solutions Architect take to satisfy the security requirements requested by the CISO?

A customer has a production application that frequently overwrites and deletes data, the application requires the most up-to-date version of the data every time it is requested.
Which storage should a Solutions Architect recommend to bet accommodate this use case?

A Solutions Architect is designing a photo application on AWS. Every time a user uploads a photo to Amazon S3, the Architect must insert a new item to a
DynamoDB table.
Which AWS-managed service is the BEST fit to insert the item?

An application relies on messages being sent and received in order. The volume will never exceed more than 300 transactions each second.
Which service should be used?

A Solutions Architect is designing an application on AWS that uses persistent block storage. Data must be encrypted at rest.
Which solution meets the requirement?

A company is launching a static website using the zone apex (mycompany.com). The company wants to use Amazon Route 53 for DNS.
Which steps should the company perform to implement a scalable and cost-effective solution? (Choose two.)

A manufacturing company captures data from machines running at customer sites. Currently, thousands of machines send data every 5 minutes, and this is expected to grow to hundreds of thousands of machines in the near future. The data is logged with the intent to be analyzed in the future as needed.
What is the SIMPLEST method to store this streaming data at scale?

A bank is writing new software that is heavily dependent upon the database transactions for write consistency. The application will also occasionally generate reports on data in the database, and will do joins across multiple tables. The database must automatically scale as the amount of data grows.
Which AWS service should be used to run the database?

A Solutions Architect is designing a new application that needs to access data in a different AWS account located within the same region. The data must not be accessed over the Internet.
Which solution will meet these requirements with the LOWEST cost?

A Solutions Architect is designing a mobile application that will capture receipt images to track expenses. The Architect wants to store the images on Amazon S3.
However, uploading images through the web server will create too much traffic.
What is the MOST efficient method to store images from a mobile application on Amazon S3?

A company requires that the source, destination, and protocol of all IP packets be recorded when traversing a private subnet.
What is the MOST secure and reliable method of accomplishing this goal.

A Solutions Architect has a multi-layer application running in Amazon VPC. The application has an ELB Classic Load Balancer as the front end in a public subnet, and an Amazon EC2-based reverse proxy that performs content-based routing to two backend Amazon EC2 instances hosted in a private subnet. The Architect sees tremendous traffic growth and is concerned that the reverse proxy and current backend set up will be insufficient.
Which actions should the Architect take to achieve a cost-effective solution that ensures the application automatically scales to meet traffic demand? (Select two.)

A company is launching a marketing campaign on their website tomorrow and expects a significant increase in traffic. The website is designed as a multi-tiered web architecture, and the increase in traffic could potentially overwhelm the current design.
What should a Solutions Architect do to minimize the effects from a potential failure in one or more of the tiers?

A web application experiences high compute costs due to serving a high amount of static web content.
How should the web server architecture be designed to be the MOST cost-efficient?
