Cloud Digital Leader Trust and security with Google Cloud Practice Question
Which TWO Google Cloud services help prevent data exfiltration from virtual machines?
⚠ Common exam trap
Google Cloud often tests the distinction between monitoring/logging services (like Access Transparency and Security Command Center) and active data exfiltration prevention controls (like VPC Service Controls and Cloud DLP), leading candidates to select options that only provide visibility rather than enforcement.
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
✓
Cloud Data Loss Prevention (DLP)
Cloud Data Loss Prevention (DLP) is correct because it enables inspection of data at rest and in motion for sensitive content (e.g., PII, credit card numbers) using predefined or custom infoTypes. When integrated with VPC Service Controls, it can block or redact sensitive data before it leaves the virtual machine's network boundary, directly preventing data exfiltration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Access Transparency
Why it's wrong here
Access Transparency logs administrative actions taken by Google personnel and provides read-only audit logs to customers, but it does not inspect data flows or implement any blocking controls. Its purpose is operational accountability, not preventing data exfiltration—it records what happened after the fact rather than stopping sensitive data from leaving your environment.
- ✗
Security Command Center
Why it's wrong here
Security Command Center (SCC) is a security and risk management platform that aggregates findings, detects vulnerabilities, and flags misconfigurations across GCP, helping you identify suspicious activity. However, it operates as a monitoring and alerting tool; it does not enforce policy or mediate data transfers, so it cannot actively prevent exfiltration, only signal potential risks for manual remediation.
- ✗
Cloud Armor
Why it's wrong here
Cloud Armor is a web application firewall and DDoS protection service that filters requests based on IP, geolocation, and custom rules at the edge of your load balancers. It is designed to block malicious HTTP/S traffic from reaching your apps, but it has no insight into data content or storage egress, and therefore cannot prevent sensitive data from being copied out of GCP services like Cloud Storage or BigQuery.
- ✓
Cloud Data Loss Prevention (DLP)
Why this is correct
Cloud Data Loss Prevention (DLP) uses content inspection with built-in detectors to identify sensitive elements like credit card numbers, PII, or credentials, and can apply transformations such as redaction, masking, tokenization, and encryption. When integrated into data pipelines or egress workflows, it can block or de-identify sensitive content before it leaves your organization, directly preventing data exfiltration at the data layer.
- ✓
VPC Service Controls
Why this is correct
VPC Service Controls lets you define security perimeters around Google Cloud services, enforcing context-aware access using identity, source IP, and API-level constraints. Resources inside a perimeter cannot be copied or retrieved from outside without explicit egress allowlists, which blocks data exfiltration by controlling the network path through which data can move, independent of content inspection.
