ADomain Name System

BDirect Link

CTransit Gateway

DPower Edge Router

Show Suggested Answer

Suggested Answer: C

IBM Cloud Transit Gateway provides network connectivity between different IBM Cloud Virtual Private Clouds (VPCs). It allows for secure, scalable, and efficient communication between resources deployed in separate VPCs, whether they are within the same region or across different regions.

How Transit Gateway Works: It acts as a central hub that facilitates the routing of traffic between multiple VPCs without the need to configure individual VPC peering connections. This simplifies network management, improves scalability, and enhances security by maintaining a single point of control.

Benefits of Transit Gateway: This service supports both private and public connectivity options and allows for routing policies that can be customized according to business needs. It also provides seamless integration with other IBM Cloud services and third-party networks.

Comparison of Other Options:

Domain Name System (A): Not used for network connectivity between VPCs.

Direct Link (B): Used for dedicated, high-speed connections from on-premises to IBM Cloud but not between VPCs.

Power Edge Router (D): Not an IBM Cloud service for inter-VPC connectivity.

Wait, Power Edge Router? That doesn't sound right.

I thought the Domain Name System was more about resolving names rather than providing connectivity. Transit Gateway sounds more appropriate, but I need to double-check that.

I vaguely recall something about Power Edge Router, but it seems more related to routing within a single VPC. Not sure if it applies here.

I’m leaning towards Direct Link, but I feel like that’s more for dedicated connections rather than just general connectivity between VPCs.

Okay, let me see. I think Domain Name System is used for name resolution, not VPC connectivity. Power Edge Router also doesn't sound right. I'm leaning towards Transit Gateway, but I'll double-check the details.
