ANS-C01 Network Management and Operations Practice Question
This ANS-C01 practice question tests your understanding of network management and operations. 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 network engineer is configuring VPC Flow Logs to deliver to an S3 bucket in a different account. The bucket policy is shown. The flow logs are not being delivered. What is the most likely reason?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The aws:SourceArn condition restricts access to a specific account, but the flow logs are from a different account
Option C is correct because the bucket policy uses the log delivery service principal from account 123456789012, but the flow logs are from a different account. The policy needs to allow access for the source account's log delivery service. Option A is incorrect because the action is correct. Option B is incorrect because the resource includes the full path. Option D is incorrect because the Principal is correct for cross-account delivery.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The Action should be s3:PutObjectAcl instead of s3:PutObject
Why it's wrong here
s3:PutObject is the correct action.
✗
The Principal must be the destination account's log delivery service
Why it's wrong here
The source account's log delivery service should be the principal.
✓
The aws:SourceArn condition restricts access to a specific account, but the flow logs are from a different account
Why this is correct
The condition limits access to logs from account 123456789012 only.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
The Resource does not include the bucket ARN itself
Why it's wrong here
The resource includes the prefix, which is sufficient.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related ANS-C01 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: The aws:SourceArn condition restricts access to a specific account, but the flow logs are from a different account — Option C is correct because the bucket policy uses the log delivery service principal from account 123456789012, but the flow logs are from a different account. The policy needs to allow access for the source account's log delivery service. Option A is incorrect because the action is correct. Option B is incorrect because the resource includes the full path. Option D is incorrect because the Principal is correct for cross-account delivery.
What should I do if I get this ANS-C01 question wrong?
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related ANS-C01 NAT questions on configuration and troubleshooting.
Are there clue words in this question I should notice?
Yes — watch for: "most likely". Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
