Network design is critical to cloud architecture especially when working with Amazon Web Services. The AWS Certified Advanced Networking Specialty exam evaluates your ability to design and implement scalable secure and resilient complex network solutions.
Key Concepts in AWS Network Design
Virtual Private Cloud (VPC) Design:
Subnetting: Learn how to segment a VPC using subnets that might be private or public. Private subnets are often used for resources that do not require direct internet connectivity whereas public subnets do.
IP Addressing: Allocate IP ranges carefully ensuring there is room for future expansion and integration with on-premises networks.
Routing: Design custom route tables to direct traffic appropriately within the VPC including traffic between subnets internet gateways and VPN connections.
Hybrid Networking:
AWS Direct Connect: Create specialized network connections that offer consistent network performance and lower latency than connections based on the internet between your on-premises data centers and AWS Direct Connect
VPN Tunneling: Use site-to-site VPN connections or VPN tunneling to safely connect your on-premises network to your AWS cloud environment. Recognize the distinctions between VPN static and dynamic routing.
Hybrid DNS: Leverage Route 53 for DNS resolution across hybrid environments, integrating your on-premises DNS with AWS services.
Network Security:
Security Groups and NACL: Create security groups to regulate inbound and outbound traffic to your resources and use Network ACLs to add an extra layer of protection at the subnet level.
DoS Protection: Use AWS Shield and AWS WAF to protect against Distributed Denial of Service attacks. Understand how scaling architectures can help to lessen the impact of DDoS attacks.
Encryption: Ensure data in transit is encrypted using protocols like TLS. Implement VPNs and secure tunnels for communication between networks.
Monitoring and troubleshooting networks:
VPC Flow Logs: Capture and analyze network traffic for security and troubleshooting purposes using VPC Flow Logs.
CloudWatch and CloudTrail: Utilize AWS CloudWatch to monitor network security and performance and use AWS CloudTrail to track API calls.
Network Performance Optimization: To maximize network performance and speed up data transfer use AWS Global Accelerator and educate yourself on how to use AWS Direct Connect.
Preparation Tips for the ANS-C01 Exam
Study AWS Documentation:
AWS offers extensive documentation on all networking services. Focus on VPC Direct Connect Transit Gateway, and Route 53. The documentation includes best practices architectural patterns and service-specific guides.
Use of online Practice Exams:
Practice exams are invaluable for getting a feel for the exam format and the types of questions you will encounter. They help identify areas where you need further study and build confidence.
Conclusion
Network design is a foundational aspect of the AWS Certified Advanced Networking Specialty exam. By mastering the key concepts and diligently preparing with practical experience, study materials, and practice exams, you'll be well-equipped to pass the ANS-C01 exam and demonstrate your expertise in AWS networking.
