Question 290 of 1,705
AWS Direct Connect Virtual Interface Types: Private, Public, Transit
This ANS-C01 practice question tests your understanding of network implementation. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are valid configurations for an AWS Direct Connect virtual interface? (Choose two.)

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. While the question asks for two, all three are valid configurations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
Private virtual interfaces use 802.1Q VLAN tagging and BGP to exchange routes between your router and the AWS side, with the VIF associated with a single VPC or a Direct Connect Gateway for multi-VPC access. Public virtual interfaces also use BGP but advertise AWS public IP prefixes, allowing you to reach services like S3 over the Direct Connect link without internet egress costs. A transit virtual interface is a variant of a private VIF that connects to a Direct Connect Gateway, which then attaches to a Transit Gateway, enabling centralized routing across multiple VPCs and on-premises networks.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
