Amazon ANS-C01 Exam Questions
- Topic 1: Network Design: The topic equips AWS networking specialists with the expertise to architect robust and optimized networking solutions. This involves designing edge network services to enhance user performance globally, integrating DNS solutions for public, private, and hybrid setups, and embedding load balancing for high availability, scalability, and security. It also addresses defining logging and monitoring strategies and creating routing frameworks between on-premises systems and the AWS Cloud, as well as across multiple AWS accounts, Regions, and VPCs.
- Topic 2: Network Implementation: It assesses the ability of AWS networking specialists to configure and deploy network architectures effectively. This includes implementing routing between on-premises systems and AWS, establishing connectivity across multiple AWS accounts, Regions, and VPCs, and configuring complex hybrid DNS setups.
- Topic 3: Network Management and Operation: The Network Management and Operation topic evaluates the capability to maintain and optimize AWS and hybrid networks. It focuses on monitoring and analyzing network traffic for troubleshooting, maintaining routing, and ensuring connectivity. This topic challenges the AWS networking specialist to demonstrate proficiency in operational excellence and performance tuning.
- Topic 4: Network Security, Compliance, and Governance: The Network Security, Compliance, and Governance topic ensures AWS networking specialists can secure and govern their network environments. It involves implementing features to meet compliance and security needs, validating security through monitoring and logging services, and maintaining data confidentiality and communication integrity.

A company has workloads that run in a VPC. The workloads access Amazon S3 by using an S3 gateway endpoint. The company also has on-premises workloads that need to access Amazon
S3 privately over a VPN connection. The company has established the VPN connection to the VPC.
Which solution will provide connectivity to Amazon S3 from the VPC workloads and the on-premises workloads in the MOST operationally efficient way?
The correct solution is to use an S3 interface endpoint and an on-premises DNS resolver. An S3 interface endpoint allows you to access Amazon S3 using private IP addresses within your VPC. An on-premises DNS resolver can be configured to forward the DNS queries for the S3 domain names to the S3 interface endpoint, so that the on-premises workloads can access Amazon S3 privately over the VPN connection. This solution is operationally efficient, as it does not require any additional infrastructure or changes to the existing workloads. The VPC workloads can continue to use the S3 gateway endpoint, which provides lower latency and higher throughput than the S3 interface endpoint.
A company has expanded its network to the AWS Cloud by using a hybrid architecture with multiple AWS accounts. The company has set up a shared AWS account for the connection to its on-premises data centers and the company offices. The workloads consist of private web-based services for internal use. These services run in different AWS accounts. Office-based employees consume these services by using a DNS name in an on-premises DNS zone that is named example.internal.
The process to register a new service that runs on AWS requires a manual and complicated change request to the internal DNS. The process involves many teams.
The company wants to update the DNS registration process by giving the service creators access that will allow them to register their DNS records. A network engineer must design a solution that will achieve this goal. The solution must maximize cost-effectiveness and must require the least possible number of configuration changes.
Which combination of steps should the network engineer take to meet these requirements? (Choose three.)
To meet the requirements of updating the DNS registration process while maximizing cost-effectiveness and minimizing configuration changes, the network engineer should take the following steps:
Create an Amazon Route 53 Resolver inbound endpoint in the shared account VPC. Create a conditional forwarder for a domain named aws.example.internal on the on-premises DNS servers. Set the forwarding IP addresses to the inbound endpoint's IP addresses that were created (Option B).
Create an Amazon Route 53 private hosted zone named aws.example.internal in the shared AWS account to resolve queries for this domain (Option D).
Create a record for each service in its local private hosted zone (serviceA.account1.aws.example.internal). Provide this DNS record to the employees who need access (Option A).
These steps will allow service creators to register their DNS records while keeping costs low and minimizing configuration changes.
A banking company has an application that must connect to specific public IP addresses from a VPC. A network engineer has configured routes in the route table that is associated with the application's subnet to the required public IP addresses through an internet gateway.
The network engineer needs to set up email notifications that will alert the network engineer when a user adds a default route to the application subnet's route table with the internet gateway as a target.
Which solution will meet these requirements with the LEAST implementation effort?
An online retail company is running a web application in the us-west-2 Region and serves consumers in the United States. The company plans to expand across several countries in Europe and wants to provide low latency for all its users.
The application needs to identify the users' IP addresses and provide localized content based on the users' geographic location. The application uses HTTP GET and POST methods for its functionality. The company also needs to develop a failover mechanism that works for GET and POST methods and is based on health checks. The failover must occur in less than 1 minute for all clients.
Which solution will meet these requirements?
A company is running business applications on AWS. The company uses 50 AWS accounts, thousands of VPCs. and 3 AWS Regions across the United States and Europe.
A network engineer needs to establish network connectivity between an on-premises data center and the Regions. The network engineer also must establish connectivity between the VPCs. On-premises users and applications must be able to connect to applications that run in the VPCs.
The company has an existing AWS Direct Connect connection that the network engineer can use. The network engineer creates a transit gateway in each Region and configures the transit gateways as inter-Region peers.
Which solution will provide network connectivity from the on-premises data center to the Regions and will provide inter-VPC communications across the different Regions?
