ANS-C01 Network Security, Compliance and Governance Practice Question
This ANS-C01 practice question tests your understanding of network security, compliance and governance. 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 using AWS Direct Connect to connect on-premises to AWS. The security team wants to encrypt all traffic traversing the Direct Connect link. Which TWO options can achieve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Establish an IPsec VPN tunnel over the Direct Connect virtual interface
Option A is correct because IPsecVPN over Direct Connect can encrypt traffic. Option D is correct because MACsec provides encryption at Layer 2 for dedicated connections. Option B is wrong because TLS is for application-level encryption, not link-level. Option C is wrong because VPC endpoints do not encrypt the Direct Connect link. Option E is wrong because Direct Connect by itself does not provide encryption.
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.
✓
Establish an IPsec VPN tunnel over the Direct Connect virtual interface
Read the scenario before looking for a memorised answer.
✓
Enable MACsec on the Direct Connect dedicated connection
Why this is correct
MACsec provides encryption at Layer 2.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use TLS on all applications
Why it's wrong here
TLS encrypts application data but not the entire link.
✗
Use VPC gateway endpoints for S3
Why it's wrong here
VPC endpoints do not encrypt the Direct Connect link.
✗
Rely on Direct Connect's physical security
Why it's wrong here
Physical security does not encrypt data.
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 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.
