Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Client VPN with split tunneling disabled
Why it's wrong here
Client VPN connects remote users to the VPC, not workload-to-workload communication.
- ✓
AWS PrivateLink with Interface VPC Endpoints
Why this is correct
AWS PrivateLink uses interface endpoints powered by HyperVNI to securely expose specific services across VPCs without VPC peering.
- ✗
AWS Direct Connect Gateway with transit VIF
Why it's wrong here
Direct Connect connects on-premises datacenters to AWS, not intra-cloud workload communication.
- ✗
Inter-Region VPC Peering with restrictive Network Security Groups
Why it's wrong here
VPC peering opens full IP routing tables between VPCs, which violates strict zero-trust least privilege isolation.
