Three of the 296 questions in this pack

Question 1

A company is planning to create a service that requires encryption in transit. The traffic must not be decrypted between the client and the backend of the service. The company will implement the service by using the gRPC protocol over TCP port 443. The service will scale up to thousands of simultaneous connections. The backend of the service will be hosted on an Amazon Elastic Kubernetes Service (Amazon EKS) duster with the Kubernetes Cluster Autoscaler and the Horizontal Pod Autoscaler configured. The company needs to use mutual TLS for two-way authentication between the client and the backend. Which solution will meet these requirements?

  1. Install the AWS Load Balancer Controller for Kubernetes. Using that controller, configure a Network Load Balancer with a TCP listener on port 443 to forward traffic to the IP addresses of the backend service Pods.
  2. Install the AWS Load Balancer Controller for Kubernetes. Using that controller, configure an Application Load Balancer with an HTTPS listener on port 443 to forward traffic to the IP addresses of the backend service Pods.
  3. Create a target group. Add the EKS managed node group's Auto Scaling group as a target Create an Application Load Balancer with an HTTPS listener on port 443 to forward traffic to the target group.
  4. Create a target group. Add the EKS managed node group’s Auto Scaling group as a target. Create a Network Load Balancer with a TLS listener on port 443 to forward traffic to the target group. ✅Correct Answer: A, Install the AWS Load Balancer Controller for Kubernetes. Using that controller, configure a Network Load Balancer with a TCP listener on port 443 to forward traffic to the IP addresses of the backend service Pods. A Network Load Balancer with a TCP listener passes the encrypted connection through untouched, so the TLS session runs from client to Pod and mutual TLS authentication works end to end. gRPC over HTTP/2 rides on that TCP connection without inspection. The AWS Load Balancer Controller provisions the NLB in IP target mode, registering Pod IP addresses directly so the Cluster Autoscaler and Horizontal Pod Autoscaler can scale to thousands of connections.

Question 2

A company is deploying a new application in the AWS Cloud. The company wants a highly available web server that will sit behind an Elastic Load Balancer. The load balancer will route requests to multiple target groups based on the URL in the request. All traffic must use HTTPS. TLS processing must be offloaded to the load balancer. The web server must know the user’s IP address so that the company can keep accurate logs for security purposes. Which solution will meet these requirements?

  1. Deploy an Application Load Balancer with an HTTPS listener. Use path-based routing rules to forward the traffic to the correct target group. Include the X- Forwarded-For request header with traffic to the targets.
  2. Deploy an Application Load Balancer with an HTTPS listener for each domain. Use host-based routing rules to forward the traffic to the correct target group for each domain. Include the X-Forwarded-For request header with traffic to the targets.
  3. Deploy a Network Load Balancer with a TLS listener. Use path-based routing rules to forward the traffic to the correct target group. Configure client IP address preservation for traffic to the targets.
  4. Deploy a Network Load Balancer with a TLS listener for each domain. Use host- based routing rules to forward the traffic to the correct target group for each domain. Configure client IP address preservation for traffic to the targets. ✅Correct Answer: A, Deploy an Application Load Balancer with an HTTPS listener. Use path-based routing rules to forward the traffic to the correct target group. Include the X- Forwarded-For request header with traffic to the targets. An Application Load Balancer with an HTTPS listener offloads TLS processing and routes requests to different target groups using path based rules on the URL. The ALB adds the X-Forwarded-For header carrying the original client IP address, so the web servers can log the real user IP for security purposes.

Question 3

A company has developed an application on AWS that will track inventory levels of vending machines and initiate the restocking process automatically. The company plans to integrate this application with vending machines and deploy the vending machines in several markets around the world. The application resides in a VPC in the us-east-1 Region. The application consists of an Amazon Elastic Container Service (Amazon ECS) cluster behind an Application Load Balancer (ALB). The communication from the vending machines to the application happens over HTTPS. The company is planning to use an AWS Global Accelerator accelerator and configure static IP addresses of the accelerator in the vending machines for application endpoint access. The application must be accessible only through the accelerator and not through a direct connection over the internet to the ALB endpoint. Which solution will meet these requirements?

  1. Configure the ALB in a private subnet of the VPC. Attach an internet gateway without adding routes in the subnet route tables to point to the internet gateway. Configure the accelerator with endpoint groups that include the ALB endpoint. Configure the ALB’s security group to only allow inbound traffic from the internet on the ALB listener port.
  2. Configure the ALB in a private subnet of the VPC. Configure the accelerator with endpoint groups that include the ALB endpoint. Configure the ALB's security group to only allow inbound traffic from the internet on the ALB listener port.
  3. Configure the ALB in a public subnet of the VPC. Attach an internet gateway. Add routes in the subnet route tables to point to the internet gateway. Configure the accelerator with endpoint groups that include the ALB endpoint. Configure the ALB's security group to only allow inbound traffic from the accelerator's IP addresses on the ALB listener port.
  4. Configure the ALB in a private subnet of the VPC. Attach an internet gateway. Add routes in the subnet route tables to point to the internet gateway. Configure the accelerator with endpoint groups that include the ALB endpoint. Configure the ALB's security group to only allow inbound traffic from the accelerator's IP addresses on the ALB listener port.
Show answer and explanation

Correct answer: D. Configure the ALB in a private subnet of the VPC. Attach an internet gateway. Add routes in the subnet route tables to point to the internet gateway. Configure the accelerator with endpoint groups that include the ALB endpoint. Configure the ALB's security group to only allow inbound traffic from the accelerator's IP addresses on the ALB listener port.

Attach an internet gateway. Add routes in the subnet route tables to point to the internet gateway. Configure the accelerator with endpoint groups that include the ALB endpoint. Configure the ALB's security group to only allow inbound traffic from the accelerator's IP addresses on the ALB listener port. The ALB must be in a private subnet with an internet gateway and routes configured so the Global Accelerator can reach it. The ALB's security group must restrict inbound traffic to only the accelerator's IP address ranges on the listener port, ensuring the application is accessible only through Global Accelerator and not directly from the internet.

Why the other options are wrong

  • A. An internet gateway without routes is non-functional; the configuration does not restrict access to the accelerator only, allowing direct internet access.
  • B. Without an internet gateway and routes, the Global Accelerator cannot reach the private ALB; this configuration is incomplete.
  • C. Placing the ALB in a public subnet defeats the purpose of restricting access to the accelerator only; direct internet access becomes possible.

What makes the ANS-C01 hard

Advanced Networking Specialty has a reputation as the hardest exam AWS runs, and it is earned: this is where network engineers and cloud architects both discover the half they do not know. The scenarios stack layers: Transit Gateway route table design across dozens of VPCs, Direct Connect with BGP communities and failover behaviour, hybrid DNS with Route 53 Resolver endpoints, and PrivateLink versus peering versus TGW trade-offs. Every question hinges on details, MTU limits, BGP path selection, security group referencing across attachments, that only surface once you have run these networks or seen the questions.

AWS is retiring this exam: the last day to take it is 31 December 2026, though certifications earned before then stay active for the standard three years. This pack has 296 practice questions for the ANS-C01, hybrid and multi-account scenarios included.
