- A
Use S3 replication with SSE-KMS to copy logs from source accounts to the logging account.
Why wrong: Logs are in CloudWatch Logs, not S3.
- B
Create a cross-account destination in the logging account, configure subscription filters in source accounts, and attach a KMS key policy that allows CloudWatch Logs in source accounts to use the key.
This enables cross-account log delivery with customer-managed KMS encryption.
- C
Create a cross-account destination in each source account and attach a resource policy that grants the logging account permission to write.
Why wrong: Destination should be in the logging account, not source.
- D
Use the default AWS-managed KMS key for CloudWatch Logs in each source account.
Why wrong: The security team wants the logging account to manage the key, not source accounts.
Quick Answer
The correct answer is to create a cross-account destination in the logging account, configure subscription filters in source accounts, and attach a KMS key policy that allows CloudWatch Logs in source accounts to use the key. This works because cross-account log delivery requires a destination resource in the central account to receive the stream, and the KMS key policy must explicitly grant the CloudWatch Logs service principal from each source account the `kms:Encrypt` and `kms:Decrypt` permissions—otherwise the service cannot write encrypted logs across accounts. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of the interplay between subscription filters, destination access policies, and cross-account KMS key policies; a common trap is assuming the KMS key policy only needs the logging account’s CloudWatch Logs principal, but the source accounts’ service principals must also be listed. Remember the triple-check: destination in the logging account, subscription filter in each source account, and KMS key policy granting the source accounts’ CloudWatch Logs service principal.
SAP-C02 Practice Question: Design Solutions for Organizational Complexity
This SAP-C02 practice question tests your understanding of design solutions for organizational complexity. 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 has a centralized logging account and multiple application accounts. Each application account sends CloudWatch Logs to a cross-account log group in the logging account. The security team wants to ensure that logs are encrypted at rest using a KMS key that only the logging account can manage. Which configuration is required?
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 cross-account destination in the logging account, configure subscription filters in source accounts, and attach a KMS key policy that allows CloudWatch Logs in source accounts to use the key.
Option D is correct because each account must have a subscription filter that sends logs to the cross-account destination, and the destination's access policy must allow the source accounts to write. Additionally, KMS key policy must grant the CloudWatch Logs service principal in the source accounts permission to use the key. Option A is wrong because using the default CloudWatch Logs encryption key does not provide customer-managed encryption. Option B is wrong because the destination is in the logging account, not in the source accounts. Option C is wrong because S3 is not used.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use S3 replication with SSE-KMS to copy logs from source accounts to the logging account.
Why it's wrong here
Logs are in CloudWatch Logs, not S3.
- ✓

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.
