It demands deep, practical intuition for routing, hybrid connectivity, and enterprise-scale security. I built this comprehensive question bank to give you a realistic, challenging environment to test your knowledge before sitting for the actual exam.Finding high-quality, up-to-date study material for the ANS-C01 is notoriously difficult. Many resources either barely scratch the surface or fail to replicate the complex, multi-layered scenario questions AWS uses. I have carefully authored these practice tests to mirror the real exam's difficulty, terminology, and domain weighting. Every single question comes with a highly detailed breakdown of why the correct answer works and exactly why the distractors are flawed. This turns the practice test itself into a powerful, standalone study guide.Whether you are configuring Transit Gateways, optimizing Direct Connect connections, or implementing highly available hybrid DNS architectures, these practice exams will expose your blind spots and solidify your cloud networking expertise.Practice Questions PreviewHere is a sample of the types of scenario-based questions you will find inside the course:Question 1: Hybrid DNS Architecture A company is connecting its on-premises data center to an AWS VPC via AWS Direct Connect. The VPC has a Route 53 private hosted zone (aws. internal. company. com). The on-premises network uses custom DNS servers for its domain (onprem. company. com). You need to ensure that resources in the VPC can resolve on-premises records, and on-premises servers can resolve the AWS private hosted zone records. Which architecture meets these requirements with the lowest operational overhead? (Select TWO)A. Create a Route 53 Resolver outbound endpoint in the VPC. Configure a Route 53 forwarding rule for onprem. company. com and associate it with the VPC, pointing to the on-premises DNS server IP addresses.B. Deploy a fleet of EC2 instances running BIND in the VPC to act as DNS forwarders between the on-premises environment and AWS.C. Configure the on-premises DNS servers to forward queries for aws. internal. company. com to the default VPC DNS resolver at the VPC IPv4 network range plus two (VPC CIDR + 2).D. Create a Route 53 Resolver inbound endpoint in the VPC. Configure the on-premises DNS servers to forward queries for aws. internal. company. com to the IP addresses of the inbound endpoint.E. Set up a DHCP options set in the VPC configured with the on-premises DNS server IP addresses and assign it to the VPC to handle all DNS resolution natively.F. Create a Route 53 public hosted zone mirroring the private hosted zone and secure it using AWS WAF and IAM resource policies.Correct Answers: A, DExplanations:Option A is CORRECT: An outbound endpoint allows DNS queries from the VPC to be forwarded to your on-premises DNS resolvers via a forwarding rule. This is the native, managed way to resolve on-premises domains from AWS.Option B is INCORRECT: While running custom EC2 DNS instances is possible, it introduces high operational overhead (patching, scaling, managing high availability) compared to using the fully managed Route 53 Resolver endpoints.Option C is INCORRECT: On-premises resources cannot query the default VPC DNS resolver (VPC CIDR + 2) directly over Direct Connect or VPN. The traffic must be routed to an inbound endpoint.Option D is CORRECT: An inbound endpoint provides IP addresses within your VPC that on-premises DNS servers can forward queries to. This allows on-premises resources to resolve records in Route 53 private hosted zones.Option E is INCORRECT: Setting the DHCP options set to point to on-premises DNS servers would break the resolution of AWS-specific internal domain names and endpoints unless the on-premises servers were configured to forward those specific queries back to AWS, creating a complex loop.Option F is INCORRECT: Creating a public hosted zone exposes internal architecture to the internet, which is a massive security risk and does not solve the private hybrid routing requirement.Question 2: Edge Networking Traffic Distribution You are designing a global media streaming application. The static web assets are stored in an S3 bucket in us-east-1, and the dynamic API backend runs on EC2 instances behind an Application Load Balancer (ALB) in eu-west-1. You need to ensure the lowest possible latency for global users, encrypt all traffic in transit, and protect the application from DDoS attacks. Which single solution provides the most optimized traffic distribution?A. Deploy an AWS Global Accelerator. Add the S3 bucket and ALB as endpoints. Use AWS Shield Advanced on the Global Accelerator.B. Create an Amazon CloudFront distribution. Configure the S3 bucket as one origin and the ALB as another origin. Use Cache Behaviors to route path-based traffic. Enable AWS WAF on the distribution.C. Set up Route 53 with Latency-based routing policies pointing directly to the S3 bucket for static assets and the ALB for dynamic traffic.D. Create a Transit Gateway spanning us-east-1 and eu-west-1. Route all user traffic through a central VPC inspection point before sending it to S3 or the ALB.E. Use an Internet Gateway with AWS Direct Connect Gateway to route user traffic globally over the AWS backbone directly to the ALB and S3 bucket.F. Deploy a Network Load Balancer in front of both the S3 bucket and the ALB, and use Route 53 Geolocation routing to distribute the traffic.Correct Answer: BExplanations:Option A is INCORRECT: Global Accelerator does not support Amazon S3 buckets as direct endpoints. It is designed for TCP/UDP traffic routing to ALBs, NLBs, EC2 instances, or Elastic IPs.Option B is CORRECT: Amazon CloudFront is the ideal service for edge networking and global content delivery. It supports multiple origins (S3 for static, ALB for dynamic), reduces latency via edge caching, and integrates seamlessly with AWS WAF and Shield for DDoS protection.Option C is INCORRECT: Route 53 alone does not cache content at the edge, nor does it inherently protect against DDoS attacks like CloudFront does. Latency routing just points the user to a DNS record; the traffic still travels over the public internet to the origin.Option D is INCORRECT: Transit Gateway is used to connect VPCs and on-premises networks. It is not an edge networking or global traffic distribution service for internet-facing end users.Option E is INCORRECT: Direct Connect Gateway is for connecting on-premises data centers to multiple VPCs globally. It does not route public internet traffic from standard web users.Option F is INCORRECT: Network Load Balancers operate at Layer 4 and cannot route HTTP/HTTPS path-based requests to distinguish between an S3 bucket and an API backend. Furthermore, S3 cannot be an NLB target.Question 3: Network Security and Segmentation Your company operates an isolated three-tier web application within a single VPC. You have identified anomalous traffic originating from a specific EC2 instance in the private application tier attempting to communicate with known malicious IP addresses on the internet via the NAT Gateway. You must block this outbound traffic immediately while allowing normal application traffic to continue. What is the most effective way to accomplish this?A. Add a deny rule to the Security Group attached to the compromised EC2 instance to block outbound traffic to the malicious IP addresses.B. Add an outbound DENY rule to the Network ACL associated with the application tier subnet blocking the malicious IP addresses.C. Terminate the NAT Gateway immediately to sever internet access for all private subnets.D. Modify the VPC Route Table associated with the private subnet to send traffic destined for the malicious IPs to a blackhole endpoint.E. Attach an IAM Role with a restrictive policy to the EC2 instance explicitly denying network access to the malicious IP range.F. Create a Route 53 private hosted zone that overrides the DNS resolution of the malicious IPs to 127.0.0.1.Correct Answer: BExplanations:Option A is INCORRECT: Security Groups are stateful and default to allowing all outbound traffic, but more importantly, AWS Security Groups do not support explicitly writing "DENY" rules. They only support ALLOW rules.Option B is CORRECT: Network Access Control Lists (NACLs) are stateless and operate at the subnet level. Crucially, NACLs support explicit DENY rules. Placing an outbound deny rule for the specific malicious IPs will immediately block the traffic from leaving the subnet.Option C is INCORRECT: Terminating the NAT Gateway would cause an immediate, catastrophic outage for all outbound internet traffic across all private subnets, taking down normal application functionality.Option D is INCORRECT: While you can route traffic to a blackhole, Route Tables map CIDR blocks, not individual IPs easily on the fly without heavy operational overhead. Furthermore, route tables are generally used for routing intent, whereas NACLs are the security boundary for explicitly denying traffic.Option E is INCORRECT: IAM roles control permissions to AWS APIs (like s3:GetObject or ec2:RunInstances). They do not control or filter raw TCP/IP network traffic leaving an instance.Option F is INCORRECT: Malicious software often uses hardcoded IP addresses rather than domain names. DNS overriding would only work if the anomalous traffic was relying on domain name resolution.Welcome to the Mock Exam Practice Tests Academy to help you prepare for your AWS Certified Advanced Networking – Specialty course.You can retake the exams as many times as you wantThis is a huge original question bankYou get support from me if you have questionsEach question has a detailed explanationMobile-compatible with the Udemy appI hope that by now you're convinced!
