Difficulty: EasyAWS Network Services

A company is expanding its cloud infrastructure and needs to connect several Amazon Virtual Private Clouds (VPCs) and on-premises networks together. To avoid managing a complex web of point-to-point connections, they want to route all traffic through a central hub. Which AWS service should the company use to meet this requirement?

  1. AWS Transit GatewayAnswer
  2. B
    VPC Peering
  3. C
    Security Groups
  4. D
    AWS CloudTrail

Answer

AWS Transit Gateway is the correct service because it acts as a central hub for routing traffic across multiple Amazon VPCs and on-premises networks, simplifying connectivity management.
AWS Transit Gateway serves as a centralized network transit hub that allows customers to interconnect multiple Virtual Private Clouds (VPCs) and on-premises networks. This eliminates the need to establish and manage a complex mesh of point-to-point connections, simplifying network routing and management.

Step-by-Step Solution

1
Identify the primary requirement in the scenario.
The company needs to connect multiple VPCs and on-premises networks using a centralized routing hub rather than complex point-to-point connections.
This establishes the criteria for selecting the appropriate networking service.
2
Evaluate the available options against this requirement.
AWS Transit Gateway is designed to act as a cloud router and central hub. VPC Peering is point-to-point, Security Groups are instance-level firewalls, and AWS CloudTrail is an auditing tool.
This narrows down the selection to the single correct service.

Key Concept

Centralized network routing and interconnection of multiple VPCs and on-premises environments using AWS Transit Gateway.
