Exam Simulator: Design High-Performing Architectures – Part B

Your company has just launched a new application that will be deployed on AWS which runs multiple components in Docker containers. Your company decides to use AWS managed infrastructure for running the containers as they do not want to manage EC2 instances.

Which of the following solution would address the requirement? (Choose two)

You are designing a service to host containers from several customers on Amazon ECS. These containers will use several AWS services. What solution will you implement in order to avoid containers from customers to get access to each other’s data?

A mobile app development company operates several apps such as social media apps, entertainment apps, and lifestyle apps that use various RESTful web APIs hosted on their on-premises data center. Due to the unprecedented growth of their company, they decided to migrate their system to AWS Cloud to scale out their resources as well to minimize costs. The company hired you to implement a solution that meets the above requirement.

Which of the following solution will you implement?

An application that you will be deploying in your VPC requires 30 EC2 instances. You need to implement a strategy to avoid a single point of failure for your EC2 instances in case of hardware failure.

Which of the following placement group will be used to address the requirement?

A new VR/AR platform is using Docker considering that application containers are optimal for running small, decoupled services. You have been tasked to implement a solution that removes the need to provision and manage servers, pay for resources per application, and improve security through application isolation by design.

Which of the following AWS service will be used for this new platform?

You have been hired by a company that is in need of a storage solution that can be simultaneously accessed by 500 servers in multiple availability zones. The servers are hosted in EC2 instances. The solution you have been tasked to implement should be able to handle the rapidly changing data at scale while still maintaining high performance. It should also be highly durable and highly available whenever the servers will pull data from it, with little need for management.

Which of the following solutions will you implement?

You are working for an audio streaming startup as an AWS Architect. You have been tasked to design a serverless application that will accept audio files uploaded by users from around the world. The application will make API calls to back-end services and save the number of uploaded files of the users to a database.

Which combination of services would provide a solution that is cost-effective while delivering the least latency?

You are working on a blockchain application in AWS which will be deployed in an Auto Scaling group of On-Demand EC2 instances and a MySQL database. It is expected that the database will have high-throughput workloads performing intensive I/O operations. As the Solutions Architect, you are required to properly set up and launch the required resources in AWS.

Which of the following is the most suitable EBS type to use for your database?

Which of the following options can be used to apply specific-settings in one go for all of the Relational database instances?

Your new application is hosted in an Auto Scaling group of EC2 instances. To improve the monitoring process, you have to configure it to keep the average aggregate CPU utilization of your Auto Scaling group at 50 percent. This should be done by specifying the scaling metrics and threshold values for the CloudWatch alarms that trigger the scaling process.

Which of the following scaling policy type you should use?
