CCSP Cloud Platform and Infrastructure Security Practice Question
A company has multiple VPCs in different cloud accounts that need to communicate with each other. They also need to enforce centralized security policies and simplify network management. Which cloud networking service should they use to create a hub-and-spoke topology?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cloud transit gateway
A cloud transit gateway allows you to connect multiple VPCs and on-premises networks through a central hub, simplifying management and enabling centralized security policies. Virtual network peering is point-to-point and does not scale well for many VPCs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Virtual network peering
Why it's wrong here
Virtual network peering connects two VPCs pairwise, so a full mesh of peerings is needed and each pair carries its own routes and policies; it provides no central hub for consolidated security enforcement. It is tempting because peering is simple for a few VPCs, and it would be correct for direct low-latency links between two networks.
- ✓
Cloud transit gateway
Why this is correct
A cloud transit gateway acts as a regional hub, peering each VPC through a single attachment rather than building a full mesh of pairwise connections. This satisfies the centralised policy enforcement and simplified management constraints, since security rules and routing are configured once at the hub across all accounts.
- ✗
Private link service
Why it's wrong here
PrivateLink provides unidirectional private access to a single service via endpoint network interfaces, not transitive VPC-to-VPC routing, so it cannot form a hub-and-spoke topology with centralised policy enforcement. It is tempting because it privately exposes individual services across accounts, which is its actual purpose.
- ✗
Virtual network endpoint
Why it's wrong here
A virtual network endpoint is a private IP target for one service, not a routing or peering construct, so it cannot interconnect multiple VPCs into a hub-and-spoke topology. It is tempting because endpoints do enable private cross-account service access, which is their genuine role.
