Difficulty: EasyAWS Network Services

A company has deployed two web applications in two different Amazon Virtual Private Clouds (VPCs) within the same AWS Region. The company needs to enable private network traffic between these two VPCs. Which AWS feature provides a direct, peer-to-peer network connection between two VPCs?

  1. A
    Security Group
  2. VPC PeeringAnswer
  3. C
    Network Access Control List
  4. D
    AWS Transit Gateway

Answer

VPC Peering
VPC Peering is the correct answer because it allows the routing of traffic between two VPCs privately using private IP addresses. It functions as a direct connection without relying on gateways, VPNs, or physical hardware.

Step-by-Step Solution

1
Identify the primary requirement.
The requirement is to establish a direct, private, peer-to-peer network connection between two Amazon VPCs.
This helps narrow down the service choices to VPC routing and peering features.
2
Evaluate the connectivity options.
VPC Peering provides a simple, direct link between two VPCs. AWS Transit Gateway is designed for connecting multiple VPCs and on-premises networks in a hub-and-spoke topology, which exceeds the simple peer-to-peer requirement.
Selecting the most appropriate service based on scale and direct routing principles.

Key Concept

VPC Peering provides a direct connection between two VPCs, allowing them to route traffic privately as if they were on the same network.
