AWS Networking Essentials Quiz: VPC, Load Balancers u0026 Auto Scaling Quiz

1. Understanding AWS VPC

   Which of the following best describes an AWS VPC (Virtual Private Cloud)? For example, if you want to control the network settings for a set of cloud resources, what would you use?

   1. A logically isolated virtual network in the AWS cloud where you can launch AWS resources
   2. A built-in AWS web server for hosting your website directly
   3. A physical data center that houses AWS servers
   4. An automated database scaling service
   5. A command-line tool for managing storage only

2. VPC Subnets

   In the context of a VPC, what is the main purpose of creating multiple subnets? For example, you might place web servers in one subnet and databases in another.

   1. To physically separate servers in different geographic locations
   2. To group resources with shared security or routing needs within the VPC
   3. To assign multiple operating systems to a single server
   4. To link two unrelated AWS accounts
   5. To enable direct billing for each AWS resource

3. Stateful vs Stateless Firewalls

   What is a key difference between a stateful firewall and a stateless firewall used with AWS networking services? For example, consider how they handle response traffic.

   1. A stateful firewall remembers connection states and allows return traffic automatically
   2. A stateless firewall remembers connection states and blocks all return traffic
   3. A stateful firewall only allows outgoing traffic, not incoming
   4. A stateless firewall encrypts all data passing through it by default
   5. A stateful firewall is used only for database connections in AWS

4. Elastic Load Balancer Function

   What does an Elastic Load Balancer (ELB) primarily do in an AWS environment? For example, when multiple users access your web application, how does ELB help?

   1. Distributes incoming network traffic across multiple targets to increase availability
   2. Creates backups of your data automatically on a schedule
   3. Monitors server CPU usage and memory at all times
   4. Manages user permissions and authentication
   5. Compresses static files served to clients

5. AWS Auto Scaling Basics

   Suppose you expect spikes in website traffic throughout the day. What is the basic function of AWS Auto Scaling in handling this scenario?

   1. Automatically adds or removes resources based on demand
   2. Installs new software updates on your servers
   3. Prevents all incoming traffic except from a fixed IP address
   4. Exports your server logs to an external location
   5. Converts files between different formats
