In this section of the AWS Certified Advanced Networking - Specialty learning path, we introduce you to the various networking and VPC services currently available in AWS that are relevant to the ANS-C01 exam.

Learning Objectives

  • Identify and describe the various networking services available in AWS
  • Describe how to configure an Amazon Virtual Private Cloud (VPC)
  • Understand how to control network traffic via Security Groups and Network Access Control Lists (NACLs)
  • Describe options for VPC connectivity, subnets, and routing
  • Understand how to share VPC resources using the AWS Resource Access Manager (RAM)
  • Identify how to evaluate the configuration of VPC resources using the VPC Reachability Analyzer


The AWS Certified Advanced Networking - Specialty certification has been designed for anyone with experience designing, implementing, and operating complex AWS and hybrid networking architectures. Ideally, you’ll also have some exposure to the nuances of AWS networking, particularly regarding the integration of AWS services and AWS security best practices. Many exam questions will require advanced level knowledge of many AWS services, including AWS networking services. The AWS Cloud concepts introduced in this course will be explained and reinforced from the ground up.


AWS Network Firewall is a fully managed service, making it easy to deploy network level protection for your Amazon Virtual Private Clouds or VPCs. There is no infrastructure to manage and can quickly be deployed and set up with just a few clicks within the AWS console. AWS Network Firewall provides the flexibility when defining firewall rules, allowing fine grain control over your network traffic, and increasing your ability to stop or block unwanted traffic. 

AWS Network Firewall also provides a way to import existing rules written in common, open source platforms, including third party intelligent integration feed source by AWS partners. We'll be talking about different deployment models available, but it is important to note that in order to essentially manage all AWS network firewalls, this service seamlessly works together with AWS Firewall Manager within an AWS organization. To learn more about the AWS Firewall Manager, please see our existing course here. Technical use cases for AWS Network Firewall, or the inspection of VPC-to-VPC traffic, filtering outbound traffic, secure AWS Direct Connect, and VPN traffic, or even just filtering Internet traffic.
