- A
Use Cloud Audit Logs to capture all API calls to Vertex AI, but do not log the actual prompts and responses
Why wrong: Audit Logs do not capture model input/output, failing the audit requirement.
- B
Enable Vertex AI model monitoring with Cloud Logging, and configure a log sink with a custom exclusion filter to redact sensitive patterns before storing
This ensures all interactions are logged but sensitive data is removed, meeting security without major performance impact.
- C
Log all prompts and responses to Cloud Storage and use a Cloud DLP job to scan and redact sensitive data periodically
Why wrong: Periodic redaction means sensitive data remains in logs temporarily, violating security requirements.
- D
Implement a custom proxy that logs all requests after stripping sensitive data, then forward to the model
Why wrong: A proxy adds latency and complexity; not ideal for performance.
Quick Answer
The correct approach is to enable Vertex AI model monitoring with Cloud Logging and configure a log sink with a custom exclusion filter to redact sensitive patterns before storage. This solution works because the exclusion filter operates in real time at the log ingestion layer, stripping patterns like API keys and passwords from prompts and responses without introducing the latency of a custom proxy or post-processing pipeline. On the Google Cloud Generative AI Leader exam, this scenario tests your ability to balance audit compliance with performance requirements—a common trap is choosing a proxy-based solution that adds round-trip delay. The key insight is that Vertex AI model monitoring natively captures the prompt-response pairs, and the log sink’s exclusion filter handles redaction inline, satisfying both the security team’s logging needs and the operations team’s latency concerns. Memory tip: think “sink and filter, not proxy and stutter”—the sink filters as it flows, keeping logs clean and speed high.
Generative AI Leader Practice Question: Business Strategies for Generative AI Solutions
This Generative AI Leader practice question tests your understanding of business strategies for generative ai solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 large enterprise is deploying a generative AI-powered code assistant for their developers. The solution uses Vertex AI with a fine-tuned Codey model. The security team requires that all prompts and responses be logged for audit purposes, but the logs must not contain sensitive information such as API keys or passwords. The operations team is concerned about high latency during peak usage. You need to design a solution that meets security requirements without compromising performance. Which approach should you take?
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
Enable Vertex AI model monitoring with Cloud Logging, and configure a log sink with a custom exclusion filter to redact sensitive patterns before storing
Option B is correct because it uses Vertex AI model monitoring with Cloud Logging to capture prompts and responses, then applies a custom exclusion filter with a log sink to redact sensitive patterns (e.g., API keys, passwords) in real time before logs are stored. This meets the security requirement for audit logging without sensitive data while avoiding the latency overhead of post-processing or a custom proxy, thus satisfying the operations team's performance concern.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that post-processing redaction (e.g., Cloud DLP) or custom proxies are acceptable for real-time logging, when in fact native streaming redaction via log sinks is required to meet both security and performance constraints.

Detailed technical explanation
How to think about this question
Vertex AI model monitoring with Cloud Logging uses a log sink that can apply exclusion filters based on regular expressions to redact sensitive data (e.g., patterns matching API keys like 'AIza...' or passwords) before logs are written to the destination (e.g., BigQuery or Cloud Storage). This is a streaming, real-time redaction approach that avoids the latency of batch jobs (Cloud DLP) or extra network hops (proxy). In practice, the exclusion filter can use the `logName` and `textPayload` fields with regex patterns to mask sensitive strings, ensuring compliance with audit requirements while maintaining sub-second latency for code assistant responses.
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.
TExam Day Tips
- 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.
