A crash course on AWS. Ramp up on AWS in minutes via a… Quiz

Quickly learn essential AWS skills, from setting up an account to deploying applications in the cloud, using step-by-step hands-on examples. Ideal for beginners aiming to build a strong mental model of modern cloud infrastructure.

1. Understanding AWS Basics

   What is the primary advantage of using a cloud provider like AWS compared to building your own data center?

   1. Requires no account setup
   2. Exclusively provides physical hardware
   3. Ability to scale quickly and pay-as-you-go
   4. Servers are always free

   Explanation: Cloud providers let you quickly scale resources up or down and only pay for what you use, saving time and money. Servers are not free—there are costs, although there may be a free tier for limited use. Cloud services typically offer virtual, not just physical, infrastructure. Creating an account is required to access cloud services.

2. Account Security Practices

   After creating a new AWS account, what is the recommended next step to ensure better security?

   1. Share the root credentials with your team
   2. Always use the root user for daily tasks
   3. Create additional user accounts with limited permissions
   4. Disable multi-factor authentication

   Explanation: Creating extra users with limited permissions reduces risk and follows best security practices. Sharing root credentials increases the potential for misuse, while using the root user daily is unsafe. Disabling multi-factor authentication also lowers security.

3. Launching Virtual Servers

   Which AWS service allows you to quickly rent and manage virtual servers for running your applications?

   1. EC2
   2. Lambda
   3. RDS
   4. S3

   Explanation: EC2 is designed to provide on-demand virtual servers for general-purpose computing. S3 is used for object storage, RDS offers managed relational databases, and Lambda runs code in response to events without managing servers.

4. Kubernetes in AWS

   Which AWS managed service simplifies the deployment and management of Kubernetes clusters?

   1. EKS
   2. CloudFormation
   3. ElasticCache
   4. Redshift

   Explanation: EKS makes managing Kubernetes clusters easier by handling cluster setup and operations. CloudFormation is for infrastructure as code, Redshift is for data warehousing, and ElasticCache is for in-memory caching—not for Kubernetes management.

5. Cloud Services and Elasticity

   What does the elasticity feature of most AWS services enable you to do?

   1. Avoid using virtual machines
   2. Lock your resources at a fixed capacity
   3. Guarantee 100% hardware uptime
   4. Scale resources up or down based on current needs

   Explanation: Elasticity allows you to adjust your resource usage dynamically, helping control costs and match demand. Locking capacity is not typical in cloud environments. No provider guarantees 100% hardware uptime, and elasticity includes but is not limited to virtual machines.
