CompTIA Cloud+ (CV0-004)Cloud ArchitectureMedium
A cloud administrator needs to implement a solution that allows multiple Virtual Private Clouds (VPCs) to communicate with each other and with on-premises networks through a central hub. This design should simplify network management and scale efficiently. Which networking component is best suited for this requirement?
- AVPN Gateway
- BDirect Connect
- CVPC Peering
- DTransit Gateway
Show answer & explanationAnswer & explanation
Correct answer: D. Transit Gateway
A Transit Gateway acts as a central hub that connects multiple VPCs and on-premises networks, simplifying network management and providing a scalable solution for inter-VPC and hybrid cloud connectivity.
Why the other options are wrong
- A. VPN Gateway connects a single VPC to an on-premises network, not multiple VPCs to each other.
- B. Direct Connect provides a dedicated private network connection to the cloud, but doesn't manage inter-VPC routing.
- C. VPC Peering connects two VPCs directly and does not scale well for many-to-many connections or on-premises integration.
Transit Gateway
A cloud networking service that acts as a central hub to connect multiple Virtual Private Clouds (VPCs) and on-premises networks, simplifying network management.
- Centralizes routing for complex network topologies.
- Scales efficiently for many-to-many connections.
- Supports both VPCs and on-premises connectivity.
Memory trick: For a 'Transit' hub, it's the 'Gateway' to connect all your 'VPCs' and 'on-premise' networks.
