AWS Certified Advanced Networking – Specialty (ANS-C01)

For IT leaders: Hybrid and multi-account AWS networks fail in costly ways: routing mistakes in Transit Gateway route tables, service traffic sent over the public internet when it could stay private, and logging setups that bury engineers in data. This course gives cloud infrastructure engineers one shared approach to designing, troubleshooting, and securing these environments while they prepare for the ANS-C01 exam.

Role fit: Assign this course to experienced cloud and network engineers. It assumes working knowledge of DNS and point-to-site VPNs. Newer staff should build foundations first.

Time investment: Plan for about 13 hours across 14 skills. Each skill runs under an hour or slightly more, so it fits a weekly cadence.

Change-management notes:

• Most demos are built in real AWS accounts, so give learners a sandbox training account.
• The course coaches cost habits, such as deleting VPC flow logs after use and relying on CloudFormation rollback.
• Direct Connect is taught through design scenarios rather than a live build, because a live build is cost-prohibitive.

How CBT Nuggets supports the outcome: Validation challenges let engineers work through scenarios such as overlapping IP ranges with or without hints, which builds real troubleshooting judgment. An included ANS-C01 practice exam helps Team Leads confirm readiness before scheduling certification attempts.

IT teams complete this training to troubleshoot, scale, and secure AWS networks with fewer escalations and less guesswork. Instead of memorizing services in isolation, your engineers work through realistic scenarios drawn directly from the course:

• Faster root-cause analysis: Engineers follow a layered troubleshooting workflow. They fix a missing outbound port 80 rule in a network ACL, confirm accepted traffic with VPC Flow Logs, then move to Traffic Mirroring when connectivity still fails. They also learn to delete flow logs that aren't needed so log data and costs don't pile up.
• Fewer routing outages at scale: Your team plans Transit Gateway route tables, associations, and propagation, including how return traffic flows back. Engineers learn the common pitfalls, such as private DNS resolution not working across inter-region Transit Gateway peering.
• Repeatable, lower-risk VPC builds: CloudFormation templates replace error-prone manual work, so engineers can deploy VPCs at scale from a single CLI command. Because failed stacks roll back automatically, teams can test changes with less risk.
• Right-sized designs for demanding workloads: Engineers practice matching architecture to requirements, such as cluster placement groups and Elastic Fabric Adapter for high-throughput machine learning, PrivateLink for private customer integrations, and AWS WAF to protect revenue-generating web apps against OWASP-class attacks.

Validation challenges let each IT Practitioner choose a guided or independent path, and the included practice exam helps Team Leads gauge readiness for ANS-C01 before learners sit the exam.

Knowledge

• How IPsec tunnels come to life in AWS Site-to-Site VPNs, and how Client VPN point-to-site access and its PKI setup differ from other cloud providers
• When to choose VPC peering, private endpoints, PrivateLink, or Transit Gateway, including the gotcha that private IPs don't resolve across Transit Gateway peers
• Direct Connect fundamentals, design scenarios, and realistic implementation expectations for hybrid connectivity
• Route 53 DNS management and CloudFront content delivery, including TLS security policy tradeoffs for modern and legacy clients
• Performance options such as cluster placement groups and Elastic Fabric Adapter for high-throughput workloads
• How AWS WAF counters OWASP-style attacks on transaction-driven web apps, alongside other AWS firewall options

Ability

• Plan and configure Transit Gateway attachments, custom route tables, propagation, and return-traffic paths across multi-account environments
• Troubleshoot connectivity step by step with NACLs, VPC Flow Logs, and Traffic Mirroring, while controlling log volume and cost
• Mass-deploy repeatable VPCs with CloudFormation templates and use automatic stack rollback to test safely
• Publish private services to customers through PrivateLink rather than fragile internet-based transfers
• Design load balancing and scaling that combine CloudWatch custom metrics, Lambda, and target groups
• Solve scenario-based validation challenges, such as overlapping IP ranges, in preparation for the ANS-C01 exam and practice exam
