Network DesignhardMultiple SelectObjective-mapped

Quick Answer

The answer is to configure a private virtual interface on the Direct Connect connection, associating it with the virtual private gateway. This is correct because a private virtual interface requires a virtual private gateway as the AWS-side termination point to enable Layer 3 connectivity between your on-premises network and a single VPC; the VGW must first be created and attached to the VPC before the private VIF can be associated with it, allowing routes from the on-premises CIDR 192.168.0.0/16 to be advertised to the VPC’s CIDR 10.0.0.0/16. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of the Direct Connect private virtual interface setup steps, often appearing in multi-step configuration questions where a common trap is confusing a private VIF with a transit VIF or forgetting that the VGW must be attached to the VPC before association. A helpful memory tip is “VGW first, then VIF”—the gateway must be ready before the interface can plug in.

ANS-C01 Network Design Practice Question

This ANS-C01 practice question tests your understanding of network design. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.

A company is designing a hybrid network using AWS Direct Connect. They have a VPC with CIDR 10.0.0.0/16 and an on-premises network with CIDR 192.168.0.0/16. They want to establish a Direct Connect private virtual interface with a virtual private gateway. Which THREE steps are required to complete the connectivity? (Choose three.)

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

Create a virtual private gateway and attach it to the VPC.

Option B is correct because a virtual private gateway (VGW) is the required AWS-side endpoint for a Direct Connect private virtual interface (VIF) to terminate on a single VPC. The VGW must be created and attached to the VPC before the private VIF can be associated with it, enabling private connectivity between the on-premises network and the VPC.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Create a Transit Gateway and attach the VPC to it.

    Why it's wrong here

    A Transit Gateway is not required; a virtual private gateway is sufficient.

  • Create a virtual private gateway and attach it to the VPC.

    Why this is correct

    The virtual private gateway is the AWS side endpoint for the Direct Connect private virtual interface.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Update the VPC route table to add a route for the on-premises CIDR pointing to the virtual private gateway.

    Why this is correct

    This route enables traffic from the VPC to reach on-premises.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Configure a private virtual interface on the Direct Connect connection, associating it with the virtual private gateway.

    Why this is correct

    The private virtual interface provides connectivity between on-premises and the virtual private gateway.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Create a customer gateway object in the AWS account.

    Why it's wrong here

    A customer gateway is used for VPN connections, not Direct Connect.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates confuse the customer gateway object (used for VPN) with the virtual private gateway (used for Direct Connect), leading them to incorrectly select Option E as a required step.

Detailed technical explanation

How to think about this question

A Direct Connect private VIF uses 802.1Q VLAN tagging and BGP (Border Gateway Protocol) to exchange routes between the on-premises router and the VGW. The VGW advertises the VPC CIDR (10.0.0.0/16) to the on-premises side via BGP, and the on-premises router advertises its CIDR (192.168.0.0/16); the VPC route table must have a static route pointing to the VGW for the on-premises CIDR to enable bidirectional traffic.

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.

Variation 1. A company is designing a hybrid network using AWS Direct Connect. They have a VPC with a CIDR of 10.0.0.0/16 and an on-premises network with CIDR 10.0.0.0/8. The company needs to ensure that traffic from the VPC to the on-premises network uses the Direct Connect connection and that traffic does not traverse the internet. Which TWO actions are required? (Choose TWO.)

medium
  • A.Attach the VPC to an AWS Transit Gateway
  • B.Create a private virtual interface (VIF) on the Direct Connect connection
  • C.Configure static routes or BGP to advertise the on-premises CIDR to the VPC
  • D.Create a public virtual interface (VIF) on the Direct Connect connection
  • E.Create a Direct Connect Gateway to connect the VPC to the on-premises network

Why B: Options B and D are correct. Option B is correct because a Private VIF is required for private IP communication. Option D is correct because static routes or BGP advertise the on-premises CIDR over the VIF. Option A is wrong because a Public VIF is for internet-routable IPs. Option C is wrong because a Direct Connect Gateway is not required for a single VPC. Option E is wrong because Transit Gateway is not required.
