AWS Certified Solutions Architect Associate (SAA-C03) - Creating a VPC Lab

The video tutorial provides a comprehensive guide on creating and managing Virtual Private Clouds (VPCs) in AWS. It begins with an introduction to VPCs, explaining their role as logical constructs for hosting instances and applications in the cloud. The tutorial navigates through the VPC console, highlighting various components like subnets, route tables, and gateways. It then details the process of creating a VPC, including setting up IP addresses and tenancy options. The video also covers subnet creation and configuration, emphasizing the importance of CIDR blocks. Finally, it introduces AWS Direct Connect as a method for connecting to VPCs, outlining its structure and benefits.

What is the primary purpose of a VPC in AWS?

• To create a secure, isolated network in the cloud

• To manage user access to AWS services

• To store large amounts of data

• To provide a platform for deploying machine learning models

Which of the following is NOT a component you can manage in the VPC console?

• Route tables

• Internet gateways

• Elastic Load Balancers

• DHCP option sets

What does the '/16' in an IP address like 172.31.0.0/16 signify?

• The number of available IP addresses

• The portion of the address that defines the network

• The default gateway address

• The portion of the address that defines the host

What is the difference between default and dedicated tenancy in a VPC?

• Default tenancy provides dedicated hardware resources

• Dedicated tenancy is less expensive

• Dedicated tenancy allows for more IP addresses

• Default tenancy shares hardware resources with other users

Why can't two VPCs communicate directly with each other by default?

• They are isolated by different AWS regions

• They are separate private networks

• They use different IP address ranges

• They require a special AWS service to connect

What is required to enable communication between two VPCs?

• A VPN or leased line

• A shared IP address range

• A direct connection to the internet

• A common AWS account

When creating a subnet, what does the CIDR block represent?

• The security settings of the subnet

• The physical location of the subnet

• The range of IP addresses available in the subnet

• The total number of subnets in a VPC

What is the significance of choosing an availability zone for a subnet?

• It determines the subnet's IP address range

• It affects the subnet's security settings

• It limits the number of instances in the subnet

• It specifies the physical location of the subnet

What is the purpose of AWS Direct Connect?

• To create additional VPCs

• To manage VPC security settings

• To provide a high-speed connection to AWS services

• To store backup data

Which IP address range is NOT considered private?

• 10.0.0.0/8

• 172.16.0.0/12

• 203.0.113.0/24

• 192.168.0.0/16
