The answer is that the Direct Connect Gateway uses ASN 64512. This is correct because the output explicitly shows the Amazon-side ASN (Autonomous System Number) set to 64512, which is a private ASN commonly assigned to AWS Direct Connect Gateways for BGP peering with on-premises routers. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, identifying direct connect gateway properties like the ASN, state, and ID format is a frequent task, often presented in a CLI or console output scenario. A common trap is confusing the gateway ID prefix—valid Direct Connect Gateway IDs always start with ‘dxgw-’, not ‘dxvif-’ or ‘vgw-’, and the state must be ‘available’ for active use. Additionally, the ownerAccount field is always present in the output, so its absence would indicate an error. For a quick memory tip: remember the gateway’s ASN as 64512, the private number that bridges your cloud and data center.
ANS-C01 Network Design Practice Question
This ANS-C01 practice question tests your understanding of network design. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
Exhibit
Refer to the exhibit. The following is an AWS CLI command output:
{
"DirectConnectGateway": {
"directConnectGatewayId": "dxgw-1234567890abcdef0",
"directConnectGatewayName": "My-DXGW",
"amazonSideAsn": 64512,
"ownerAccount": "123456789012",
"state": "available"
}
}
Based on the output, which of the following is true?
Refer to the exhibit. The following is an AWS CLI command output:
{
"DirectConnectGateway": {
"directConnectGatewayId": "dxgw-1234567890abcdef0",
"directConnectGatewayName": "My-DXGW",
"amazonSideAsn": 64512,
"ownerAccount": "123456789012",
"state": "available"
}
}
A
The Direct Connect Gateway uses ASN 64512
The amazonSideAsn is set to 64512.
B
The Direct Connect Gateway is in a 'deleted' state
Why wrong: The state is 'available'.
C
The Direct Connect Gateway is a virtual private gateway
Why wrong: The ID format dxgw indicates a Direct Connect Gateway, not a virtual private gateway (vgw).
D
The Direct Connect Gateway is owned by a different account
Why wrong: The ownerAccount is the same as the account making the call.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Direct Connect Gateway uses ASN 64512
Option A is correct because the output shows a Direct Connect Gateway with an Amazon-side ASN of 64512. Option B is wrong because the state is 'available'. Option C is wrong because the ID starts with 'dxgw'. Option D is wrong because ownerAccount is present.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
