The answer is to enable Route 53 Resolver query logging and publish to an S3 bucket. This is correct because Route 53 Resolver query logging captures all DNS queries made by resources within a VPC, including both forward and reverse lookups, and can natively export those logs directly to Amazon S3 for long-term compliance storage. On the AWS Certified Security Specialty SCS-C02 exam, this question tests your ability to distinguish DNS-specific logging from network-level or API-level logging services. A common trap is confusing VPC Flow Logs, which log IP traffic metadata but not DNS query content, with Route 53 Resolver logs. Another pitfall is assuming CloudWatch Logs is required as an intermediary, but Route 53 Resolver can publish directly to S3 without additional configuration. Remember the memory tip: “DNS queries need Resolver logs, not Flow Logs or CloudTrail.”
SCS-C02 Security Logging and Monitoring Practice Question
This SCS-C02 practice question tests your understanding of security logging and monitoring. 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.
A company uses Amazon Route 53 for DNS and wants to log all DNS queries made from its VPC. The logs must be stored in Amazon S3 for compliance purposes. Which solution meets these requirements?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Route 53 Resolver query logging and publish to an S3 bucket.
Option B is correct because Route 53 Resolver query logs can log DNS queries made by resources within a VPC and can be exported to S3. Option A is wrong because VPC Flow Logs capture IP traffic, not DNS queries. Option C is wrong because CloudWatch Logs can capture logs but not directly from Route 53 Resolver without additional configuration. Option D is wrong because AWS CloudTrail does not log DNS query content.
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.
✓
Enable Route 53 Resolver query logging and publish to an S3 bucket.
Why this is correct
Route 53 Resolver query logging captures DNS queries made by resources in your VPC and can deliver logs to S3.
Related concept
Read the scenario before looking for a memorised answer.
✗
Install a CloudWatch Logs agent on each EC2 instance and configure it to send DNS logs to CloudWatch Logs.
Why it's wrong here
This would only capture DNS queries from EC2 instances, not from other resources like Lambda or RDS.
✗
Enable AWS CloudTrail for DNS API calls and deliver to an S3 bucket.
Why it's wrong here
CloudTrail logs API calls to Route 53, not the actual DNS queries.
✗
Enable VPC Flow Logs and publish to an S3 bucket.
Why it's wrong here
VPC Flow Logs capture network traffic metadata, not DNS query logs.
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.

Variation 1. A company is using Amazon Route 53 and wants to log DNS queries for investigative purposes. The logs must be stored in a centralized S3 bucket in the security account. What is the MOST efficient way to achieve this?
medium
A.Enable VPC Flow Logs and analyze DNS traffic.
B.Enable CloudWatch Logs for Route 53 and stream to a Lambda function that writes to S3.
✓ C.Configure Route 53 Resolver query logging to deliver to the central S3 bucket.
D.Use a custom Lambda function to poll Route 53 logs and write to S3.
Why C: Option B is correct because Route 53 resolver query logs can be sent directly to S3, and by using AWS Organizations, you can centralize logging. Option A is wrong because CloudWatch Logs adds an extra step. Option C is wrong because VPC Flow Logs are for network traffic, not DNS queries. Option D is wrong because Route 53 does not have a built-in Lambda integration for this purpose.
