AWS Certified Advanced Networking - Specialty Practice Test

The AWS Certified Advanced Networking - Specialty (ANS-C01) focuses on designing and implementing complex network architectures across AWS and hybrid environments. The work involves connecting VPCs, AWS Regions, and on-premises networks while managing traffic paths, private access, routing behavior, and resilience at scale.

About the AWS Certified Advanced Networking - Specialty Exam

Advanced networking decisions include choosing between VPC peering and hub-based connectivity, planning route propagation, and controlling whether traffic can pass transitively between network attachments. Hybrid designs require attention to Direct Connect and Site-to-Site VPN connectivity, tunnel redundancy, routing separation, and continuity when links fail. DNS and service access also shape traffic flows: architects may use Route 53 routing policies to direct users and gateway endpoints to reach supported AWS services privately. Centralized inspection and egress patterns require careful placement of shared network resources and route tables so that traffic follows intended paths. These tasks call for tracing packet flow, identifying routing limits, and balancing isolation, scalability, availability, and operational complexity across connected environments.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A global application needs DNS responses to send users to the AWS Region that is geographically closest to them. Which Amazon Route 53 routing policy should be used?

  1. AGeolocation routing
  2. BLatency-based routing
  3. CWeighted routing
  4. DFailover routing
Show answerCorrect answer: A

Geolocation routing lets Route 53 answer DNS queries based on the user’s geographic location, which is the best match for directing users to a nearby Region.

Question 2

A company needs two VPCs in the same AWS Region to exchange traffic privately, but the design should not support transitive routing to other networks. Which option is the most direct solution?

  1. AVPC peering connection
  2. BAWS Transit Gateway
  3. CSite-to-Site VPN
  4. DGateway Load Balancer endpoint
Show answerCorrect answer: A

VPC peering provides private IP connectivity directly between two VPCs. It is simple and low-latency, but it does not provide transitive routing through a hub.

Question 3

A network architect needs multiple VPCs to use the same set of centralized inspection and egress resources in another VPC, with transitive routing between VPC attachments and support for scaling beyond a simple point-to-point setup. Which AWS service is the best fit?

  1. AVPC peering
  2. BAWS Transit Gateway
  3. CAWS Direct Connect
  4. DInternet Gateway
Show answerCorrect answer: B

AWS Transit Gateway is designed for hub-and-spoke connectivity across multiple VPCs and on-premises networks. Unlike VPC peering, it supports transitive routing through a central routing hub.

Question 4

A company wants to increase availability for a Site-to-Site VPN connection by using two separate tunnels provided by AWS. If one tunnel becomes unavailable, the other should continue carrying traffic automatically. What is the primary purpose of this dual-tunnel design?

  1. AHigh availability and failover
  2. BPacket mirroring
  3. CLayer 2 bridging
  4. DDNS-based geolocation routing
Show answerCorrect answer: A

AWS Site-to-Site VPN includes redundant tunnels so that traffic can fail over automatically if one tunnel or its path becomes unavailable. This improves resilience without changing application behavior.

Question 5

A company needs to give multiple Amazon VPCs private access to Amazon S3 using routes, without creating interface endpoints in each subnet. Which solution should they use?

  1. AGateway VPC endpoint for Amazon S3
  2. BInterface VPC endpoint for Amazon S3
  3. CInternet gateway
  4. DNAT gateway
Show answerCorrect answer: A

A gateway VPC endpoint is the standard route-table-based way to privately reach Amazon S3 and DynamoDB from VPCs without using public IP addresses or the internet.

Question 6

A security team wants to inspect traffic between many VPCs and on-premises networks using a centralized hub that supports transitive routing. Which AWS service is the best fit?

  1. AAWS Transit Gateway
  2. BAmazon Route 53
  3. CAWS Certificate Manager
  4. DAmazon EBS
Show answerCorrect answer: A

AWS Transit Gateway is commonly used as a centralized routing hub for multiple VPCs and on-premises connections, and it supports transitive routing between attachments.

Question 7

An application in a VPC must access Amazon S3 without sending traffic over the public internet and without using a public IP address on the instances. Which solution best meets this requirement?

  1. ACreate an S3 gateway VPC endpoint and update route tables as needed
  2. BAttach an internet gateway and disable public DNS resolution
  3. CCreate a NAT instance in a public subnet
  4. DUse a VPN connection to AWS from the same VPC
Show answerCorrect answer: A

Gateway VPC endpoints for S3 keep traffic to the service on the AWS network and avoid internet exposure. They are the standard choice for private access to S3 from a VPC.

How to use this practice test

US Practice Tests provides free access to a bank of 50 practice questions. Each session presents up to 20 questions selected at random, with results shown when the session ends. Use the scenarios to test how well you distinguish connectivity options, trace routes, and evaluate private access or redundancy designs.

Preparation tips

  • Draw packet paths for VPC peering and Transit Gateway designs, noting where transitive routing is and is not supported.
  • Compare gateway endpoints with interface endpoints, including how route tables direct traffic to Amazon S3.
  • Sketch a hybrid connectivity design with Direct Connect and redundant Site-to-Site VPN tunnels; identify the failure each path can tolerate.
  • Practice tracing route propagation and attachment associations through a Transit Gateway hub-and-spoke topology.
  • For DNS scenarios, distinguish geographic routing from other Route 53 policies by the precise traffic-selection requirement.
