ANS-C01 Network Implementation Practice Question
Which THREE of the following are valid configurations for an AWS Direct Connect virtual interface? (Choose three.)
⚠ Common exam trap
AWS often tests the distinction between the three valid virtual interface types (private, public, transit) and tricks candidates by including 'VPN virtual interface' or 'Hosted virtual interface' as plausible-sounding options, exploiting confusion about how VPNs and partner-provisioned connections relate to Direct Connect.

Correct answer & explanation
✓
Private virtual interface
AWS Direct Connect supports three types of virtual interfaces: private, public, and transit. A private virtual interface (B) connects your on-premises network to an Amazon VPC using private IP addresses. A public virtual interface (E) provides access to AWS public services (e.g., S3, DynamoDB) over the Direct Connect link. A transit virtual interface (D) enables connectivity from a Direct Connect gateway to one or more transit gateways, allowing access to multiple VPCs and VPN connections. All three are valid configurations.
