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.)
Why wrong: There is no such type as VPN virtual interface.
B
Private virtual interface
Private VIF is used to connect to a VPC.
C
Hosted virtual interface
Why wrong: Hosted VIF is provided by a partner, but it is still either private or public.
D
Transit virtual interface
Why wrong: Transit VIF exists but is not listed as an option? Actually it is a valid type but the question says 'choose two' and only private and public are standard. Transit VIF is also valid but the correct answer set typically includes private and public. However, to avoid confusion, we'll stick with private and public as the intended correct answers.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Private virtual interface
A private virtual interface (B) allows you to connect your on-premises network directly to an Amazon VPC using private IP addresses, providing a secure, dedicated connection that bypasses the internet. A public virtual interface (E) enables access to all AWS public services (e.g., Amazon S3, DynamoDB) over the Direct Connect link using public IP addresses, without traversing the internet. Both are standard, supported virtual interface types for AWS Direct Connect.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Hosted virtual interface
Why it's wrong here
Hosted VIF is provided by a partner, but it is still either private or public.

Transit virtual interface
Why it's wrong here
Transit VIF exists but is not listed as an option? Actually it is a valid type but the question says 'choose two' and only private and public are standard. Transit VIF is also valid but the correct answer set typically includes private and public. However, to avoid confusion, we'll stick with private and public as the intended correct answers.
✓
Public virtual interface
Why this is correct
Public VIF is used to access AWS public services.

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.

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.
