20+ practice questions focused on Networking and Content Delivery — one of the most tested topics on the AWS Certified SysOps Administrator Associate SOA-C02 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Networking and Content Delivery PracticeA company has two VPCs in different AWS regions (us-east-1 and eu-west-1) that are peered. Applications in both VPCs need to communicate using private IP addresses. The ping tests are successful, but the latency is significantly higher than expected. Which change is most likely to improve the latency between the VPCs?
Explanation: Enabling DNS resolution for the VPC peering connection allows instances to resolve public DNS hostnames to the private IP addresses of the peered VPC. Without this, DNS queries may return public IP addresses, forcing traffic to traverse the internet or NAT gateways, which adds significant latency. By resolving to private IPs, traffic stays within the AWS backbone, reducing latency.
A company has deployed a web application on Amazon EC2 instances behind an Application Load Balancer (ALB). The application's IP addresses are used by a third-party service to allowlist traffic. The EC2 instances are part of an Auto Scaling group that may scale up and down. The SysOps administrator needs to ensure that the third-party service always has the current IP addresses of the ALB without requiring manual updates. Which solution should the administrator implement?
Explanation: AWS Global Accelerator and a Network Load Balancer (NLB) with Elastic IPs both provide static IP addresses in front of an ALB. The NLB can be placed in front of the ALB by setting the ALB as a target. This is a well-supported AWS pattern and satisfies the requirement without manual updates. Therefore, both A and D are correct.
A company has two VPCs in the same AWS region. VPC A hosts a web application, and VPC B hosts a database. The SysOps administrator needs to enable private IP communication between the two VPCs without using the public internet. The administrator wants a simple, low-cost solution that uses the AWS network backbone. Which AWS service should be used?
Explanation: VPC Peering allows direct, private IP connectivity between two VPCs using the AWS network backbone without traversing the public internet. It is the simplest and most cost-effective solution for connecting exactly two VPCs in the same region, as there are no additional hourly charges beyond data transfer costs, and no intermediate devices or bandwidth limitations are introduced.
A company has three VPCs in the same AWS region: VPC A (production), VPC B (development), and VPC C (shared services). The VPCs have overlapping CIDR blocks (e.g., VPC A: 10.0.0.0/16, VPC B: 10.0.0.0/16, VPC C: 10.1.0.0/16). The SysOps administrator needs to enable private IP communication between VPC A and VPC C, and between VPC B and VPC C, but not between VPC A and VPC B. The solution must also support a growing number of VPCs in the future. Which AWS service should be used?
Explanation: AWS Transit Gateway can handle VPCs with overlapping CIDR blocks by using separate route tables for each VPC attachment. This allows VPC A and VPC B to both communicate with VPC C while remaining isolated from each other. The service also scales easily as more VPCs are added. PrivateLink (option B) only provides access to specific services via VPC endpoints, not general private IP communication between all resources in the VPCs. VPC peering (option C) does not support overlapping CIDRs. Site-to-Site VPN (option D) is more complex and unnecessary for this use case.
A company runs a gaming application that uses Amazon EC2 instances to handle real-time multiplayer sessions. The application requires low-latency communication with users around the world. The SysOps administrator needs to accelerate content delivery for non-cacheable, dynamic content (such as real-time game state updates) and also provide static asset delivery. The solution must support both TCP and UDP traffic. Which AWS service should be used?
Explanation: AWS Global Accelerator is the correct choice because it uses the AWS global network and Anycast IPs to route TCP and UDP traffic to the optimal endpoint, providing low-latency performance for non-cacheable dynamic content like real-time game state updates. It also supports static asset delivery by directing traffic to origins such as Application Load Balancers or EC2 instances, and it handles both TCP and UDP protocols natively, which is essential for real-time multiplayer gaming.
