20+ practice questions focused on Ensuring Data Protection — one of the most tested topics on the Google Professional Cloud Security Engineer exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Ensuring Data Protection PracticeA security engineer needs to ensure that all customer data stored in Cloud Storage is encrypted at rest using keys that the organization manages and rotates themselves. Which encryption option should they use?
Explanation: Customer-managed encryption keys (CMEK) using Cloud KMS is the correct choice because it allows the organization to create, manage, and rotate their own encryption keys for Cloud Storage data at rest, while still leveraging Google's infrastructure for encryption. CMEK uses Cloud KMS to wrap the data encryption keys (DEKs) with a customer-managed key encryption key (KEK), ensuring the organization retains control over key lifecycle operations such as rotation, disabling, and destruction, meeting the requirement for self-managed key rotation.
A company uses Cloud KMS with a key purpose of ENCRYPT_DECRYPT. They need to rotate the key automatically every 30 days. What must they configure?
Explanation: Option A is correct because Cloud KMS allows you to set a rotation period directly on a key (a CryptoKey resource) when its purpose is ENCRYPT_DECRYPT. Configuring a rotation period of 30 days on the key enables automatic, scheduled rotation, where Cloud KMS creates a new key version every 30 days and promotes it to primary, without any manual intervention.
Which Google Cloud service provides near-real-time logs when Google administrators access your customer content?
Explanation: Access Transparency logs provide detailed information about actions taken by Google staff when accessing customer data. Access Approval is a separate feature that requires approval before access. Audit Logs is a broader category. Cloud DLP is for data loss prevention.
A company stores API keys in Secret Manager. They want to automatically rotate the secret every 60 days and have a Cloud Function triggered after each rotation to update dependent services. What is the correct approach?
Explanation: Secret Manager can set a rotation period and publish a Pub/Sub message upon rotation. A Cloud Function can subscribe to that topic and execute updates. Directly triggering from Secret Manager is not possible. Cloud Scheduler is not needed.
A company has a Cloud Storage bucket containing CSV files with sensitive data. They want to use Cloud DLP to scan the files for personally identifiable information (PII) and automatically redact (replace) any detected credit card numbers before the data is used by downstream analytics. What type of job should they create?
Explanation: Option D is correct because Cloud DLP's de-identification jobs are designed to automatically transform sensitive data, such as redacting credit card numbers using a masking transform. This job type directly applies the redaction to the CSV files in Cloud Storage without requiring external triggers or custom functions, making it the most efficient and native solution for automated redaction before downstream analytics.
