The local power company has recently installed a new power grid within the community. They are working with the local government to acquire funding for a second power grid but must show data that demonstrates the cost reductions and how that translates to increased consumption time windows. This data needs to be kept for a minimum of 10 years in case of an audit or inquiry by a government agency. The power company wants to engage the community and gain their support, as their individual and communal power consumption is reflected in the data. The CEO has decided that the company will now begin processing the big data in real-time through the use of Amazon Kinesis. The architecture has been developed with an intermediate and backup Amazon Simple Storage Service (Amazon S3) bucket for potential delivery failures and source records. What other services should be used for transformed records after they are processed by Amazon Kinesis Data Firehose? a. Amazon Elastic Block Store (Amazon EBS) b. Amazon Elasticsearch Service (Amazon ES) c. Amazon Glacier d. Amazon Simple Storage Service (Amazon S3) e. Amazon Redshift cluster (maybe multiple answers)

Background: A startup company wants to host its Python and React-based application (Backend: Python API and Frontend React) using AWS. But they are not familiar with the AWS cloud platform. They want to ensure that the application is secure, scalable, highly available, and cost-efficient. As a solutions architect, you have to design a proper solution to meet their below requirements. Goal: To architect a solution that is secure, scalable, highly available, and cost-effective using AWS. Requirements: - They are concerned about the security of the application, so they have decided to isolate their network from the rest of the customers virtually. Set up a secure virtual network where only the frontend of the application is accessible by users and not the database. - Execute the React application code using AWS Elastic Beanstalk. Ensure that the source code of the web application is automatically picked, pushed to the master branch, and deployed on the servers. - Ensure all the UI images served to the frontend application code are provisioned via a secure storage unit. - There should be enough backups for both the web and database servers, so if the setup crashes, we can launch a new one from the disaster recovery backups. - They are uncertain about the traffic pattern, how low or high it can be, so they want the web application to be running on at least two EC2 instances all the time, and when there is a high load, they must burst up to four instances in total. - The web application should be highly available, even if any VM fails to respond to queries, there should be a mechanism to switch the connection to another healthy VM automatically. - Automate the download of all the activity logs into a CSV file, create a stream of data, analyze it, and display it via a dashboard. - The web application should also be cached globally, so users worldwide can access it with low latency.
Activity: Design a VPC Scenario: You have a small business with a website that is hosted on an Amazon Elastic Compute Cloud (Amazon EC2) instance. You have customer data that is stored in a backend database that you want to keep private. You want to use Amazon VPC to set up a VPC that meets the following requirements: • Your web server and database server must be in separate subnets. • The first address of your network must be 10.0.0.0. Each subnet must have 256 total IPv4 addresses. • Your customers must always be able to access your web server. • Your database server must be able to access the internet to make patch updates. • Your architecture must be highly available and use at least one custom firewall layer.
