Question 7
There is a highly available application in AWS. An administrator runs this application. The administrator needs a file storage layer which can share between instances and at the same time scale the platform more effectively. Which AWS service should the administrator use to perform this task?

Question 8
An enterprise is planning to run a service on AWS. This service is going to provide offsite backups on phones and laptops for images. The solution should be capable of supporting millions of consumers. Each consumer will have thousands of images. Although the images are going to be retrieved occasionally, the option for immediate retrieval should be there. Which cost-effective storage version would you use in this case?

Question 9
A Solutions Architect is in the process of designing a solution which stores and archives business documents. He has assessed and determined that Amazon Glacier would be the apt solution. The only catch is that, within 10 minutes of a retrieval request, the data must be delivered. Which Amazon Glacier feature will satisfy the above requirement?

Question 10
There is a data processing application in AWS. The job of that application is to retrieve data from an internet service. The Solutions Architect has to design a widely available solution. This solution will help in assessing this data without causing any sort of bandwidth constraints on the application traffic. Which Solution would you choose?

Question 11
You are in the process of analyzing the Auto Scaling events for your application. While reviewing, you realize that the application is scaling up and down numerous times within the same hour. Your task is to optimize expenses while maintaining elasticity. What design choices would you follow?

Question 12
An enterprise is hosting a prominent web application. This application is connected to an Amazon RDS MySQL DB instance. This instance is running in a private VPC subnet. The subnet was developed using default ACL settings. Only the consumers on an SSL connection is entitled to access the web servers. We have to also note that the database should only be accessible to web servers in a subnet which is public. Your task is to mention two solutions which satisfy the above conditions. Make sure your choices do not impact the normal running of other applications.

Question 13
The primary task of an application is to read and write objects to an S3 bucket. After deploying the application the architect realizes that the read/write traffic is very steep. What must the architect do in order to maximize the performance of the Amazon S3?

Question 14
Imagine you are about to deploy a web application on Amazon EC2. This application must call AWS APIs. What method would you choose to safely pass credentials to the web application?

Question 15
There is a website which is running on EC2 Instances at the back of an ELB Application Load Balancer. The instances are running in an Auto Scaling Group spanning numerous Availability Zones. It is delivering numerous big files, which are kept on a shared Amazon EFS file system. Every time a user demands these digital assets, the enterprise needs to avoid delivering the files from EC2 Instances. The user experience of the website needs to improve. What should the company do?

Question 16
A Solutions Architect is in the process of designing a system. This system is highly scalable and is utilized to track records. The option to immediately download these records must remain available for up to 3 months. After 3 months these records must undergo deletion. What is the most appropriate decision to take in this use case?

Question 17
A consulting enterprise uses various AWS resources from numerous AWS services which include, Amazon VPC, DynamoDB, IAM, Amazon RDS and, Amazon EC2. They are continuously building large architectures for their consumers. The architecture blueprints are ready in the form of diagrams but the enterprise is not able to use these diagrams to automatically create their resources. What service should the company choose to help in this scenario?

Question 18
The security policy of a business organization needs a web application to encrypt data before writing to the disk. Which solution is best suited to handle the above-mentioned requirement?

Question 19
Imagine an application is currently storing its entire data on Amazon EBS Volumes. We must make sure to back up all EBS volumes properly, spanning numerous Availability Zones. What is the strongest way to backup the volumes?

Question 20
Imagine there is a retailer. He exports data every day from its transactional databases into an S3 bucket located at Sydney. The Data Warehousing team of the retailer is keen on importing this data into a former Amazon Redshift cluster in their VPC, located at Sydney. The Corporate Security Policy of the enterprise states that the data can only be transferred within a VPC. What 2 steps would you undertake to satisfy the security policy?

Question 21
A team is in the process of building an application. This application should persist and index JSON data in a widely available data store. There is high application traffic. Although the traffic is high the latency of data access should be steady. The team has to choose a service to satisfy the above condition. Which service is it?

Question 22
An enterprise is currently hosting a multi-language website on AWS. This website is served using CloudFront. The language is mentioned in the HTTP request as stated below.
http://d11111f8.cloudfront.net/main.html?language=de
http://d11111f8.cloudfront.net/main.html?language=en
http://d11111f8.cloudfront.net/main.html?language=es
We need to configure AWS CloudFront to deliver cached data in the right language. How would you configure AWS CloudFront?

Question 23
A Solutions Architect is in the process of designing a web page. It will be used primarily for registration of events. The architect requires a managed service to dispatch a text message every time a user signs up for an event. State the best AWS service which the architect can use.

Question 24
A Solutions Architect is given the responsibility of designing a shared service on Amazon ECS. This service will host containers from numerous consumers. These containers are using many AWS services.
