- A
Immediately revoke all service account keys and reissue them, then reset all user passwords.
Why wrong: This is a reactive security measure but not a investigation step; it may be taken after analysis.
- B
Enable Cloud IDS to detect similar attacks and block the malicious IP address.
Why wrong: Cloud IDS is for real-time network detection, not historical investigation of storage access.
- C
Use Cloud Logging to analyze Cloud Audit Logs and identify the user who accessed the bucket and the associated context.
Cloud Audit Logs record all resource access and are the primary source for investigating unauthorized access.
- D
Export VPC Flow Logs to BigQuery and analyze for the attacker's IP address.
Why wrong: VPC Flow Logs show network flows but do not include user identity or API-level access to Cloud Storage.
Cloud Digital Leader Trust and security with Google Cloud Practice Question
This GCDL practice question tests your understanding of trust and security with google cloud. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 multinational corporation operates a hybrid cloud environment with on-premises data centers connected to Google Cloud via Dedicated Interconnect. The company uses Cloud Storage to store sensitive financial data and has enabled Cloud Audit Logs for admin activities. Recently, the security team noticed that an unknown actor accessed a bucket containing customer personally identifiable information (PII). The access occurred from an IP address outside the corporate network. The security team suspects that an employee's Google Cloud credentials were compromised. They need to investigate the incident thoroughly and determine the extent of the breach. The company has enabled VPC Flow Logs, but they are not sure how to correlate the audit logs with network flows. They also want to ensure that similar incidents are prevented in the future. What should the security team do first to investigate the incident?

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
Use Cloud Logging to analyze Cloud Audit Logs and identify the user who accessed the bucket and the associated context.
Option C is correct because the first step in investigating a suspected credential compromise is to analyze Cloud Audit Logs to identify which user accessed the bucket, from what IP address, and at what time. This provides the primary leads for the investigation. Option A is wrong because immediately revoking all keys and resetting passwords may disrupt operations and should only be done after confirming the compromise and identifying affected accounts. Option B is wrong because Cloud IDS is a network threat detection service that monitors network traffic for anomalies, but it does not provide historical logs of who accessed a specific bucket. Option D is wrong because VPC Flow Logs show network traffic but do not identify the user or the specific API calls made to Cloud Storage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
