A large enterprise with multiple VPCs in several AWS Regions around the world needs to connect and centrally manage network connectivity between its VPCs. Which AWS service or feature meets these requirements?
Transit Gateway was in the scope before but they probably remove it from CCP curriculum later. I'm studying with the exam guide and for 24.02.2023, transit gateway is not in the scope
A. AWS Direct Connect >> provides a dedicated network connection between on-premises data centers and AWS,
Correct -> B. AWS Transit Gateway >> helps centralize network management, making it easier to connect and manage multiple VPCs across AWS Regions with minimal complexity.
C. AWS Site-to-Site VPN >> connects on-premises networks to AWS VPCs over secure IPsec VPN tunnel
D. VPC endpoints >> connect private resources within a VPC to other AWS services
AWS Transit Gateway is a fully managed service that simplifies the connectivity and routing between VPCs and on-premises networks. It acts as a hub that enables inter-VPC communication and connectivity to on-premises data centers or remote networks.
With AWS Transit Gateway, the large enterprise can create a single gateway and establish peering connections with multiple VPCs across different AWS Regions. This allows for centralized management and control of network traffic between VPCs, simplifying network architecture and reducing administrative overhead.
AWS Transit Gateway is a service that simplifies network connectivity between VPCs, VPNs, and on-premises networks. It allows the company to centrally connect to multiple VPCs in different AWS regions using a single gateway, making it easier to manage large-scale network connectivity.
If you mean VPC Peering then VPC peering has limitations :
-VPC peering does not support transitive peering relationships
-Difficult to manage at scale
I think the answer should be "C" because of the below reason:
A) AWS Direct connect --> Involves VPC and on premise infra ( So wrong )
B) AWS Transit gateway --> Involves VPC and on premise infra ( so wrong )
D) VPN endpoints ( not relevant )
C) Connects between two VPC ( So i thing this could
be the right one )
AWS Transit Gateway routes all traffic to and from each VPC or VPN, and you have one place to manage and monitor it all.
