- A
Create a trail in the management account that applies to all accounts in the organization.
A trail applied to the organization logs all accounts.
- B
Enable default encryption with SSE-S3 on the S3 bucket where CloudTrail delivers logs.
Why wrong: CloudTrail S3 buckets can use SSE-S3, but this is default; KMS with customer key is needed for encryption control.
- C
Configure CloudTrail to send logs to Amazon CloudWatch Logs and enable encryption using an AWS KMS key.
Why wrong: CloudWatch Logs encryption uses KMS, but this does not prevent deletion of S3 log files.
- D
Enable S3 Object Lock on the destination S3 bucket to prevent log file deletion.
S3 Object Lock with retention mode prevents deletion.
- E
Enable CloudTrail Insights to detect unusual API activity.
Why wrong: CloudTrail Insights is for anomaly detection, not encryption or deletion prevention.
DOP-C02 Security and Compliance Practice Question
This DOP-C02 practice question tests your understanding of security and compliance. 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 wants to enable AWS CloudTrail to log all API calls across multiple accounts in AWS Organizations. The security team requires that logs be encrypted at rest and that any unauthorized deletion of log files be prevented. Which TWO actions should the security team take? (Choose TWO.)
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 trail in the management account that applies to all accounts in the organization.
Option A is correct because enabling CloudTrail for all accounts in the organization ensures centralized logging. Option D is correct because S3 Object Lock prevents deletion of log files. Option B is incorrect because KMS with a customer managed key provides encryption, but the key must be created beforehand, not just enabled. Option C is incorrect because CloudWatch Logs encryption uses KMS, not S3 SSE. Option E is incorrect because CloudTrail can be configured to log management events by default, and this is not about data events.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Why it's wrong here
CloudTrail Insights is for anomaly detection, not encryption or deletion prevention.
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.
