Google Updated Professional-Cloud-Security-Engineer Exam Questions and Answers by payton

The best way to describe security responsibilities when using a Google Cloud service, especially a managed one like a managed AI service, is to invoke the Shared Responsibility Model.

This model clarifies that Google secures the underlying infrastructure (the hardware, data centers, and the service platform itself), while the customer (your organization) retains responsibility for security in the cloud, specifically: data, access controls (IAM), and operational monitoring.

Extracts:

"This division of duties is defined by the Shared Responsibility Model, a framework that clarifies the security responsibilities of both the cloud provider and the customer." (Source 3.2)

"While cloud providers secure the infrastructure, customers must take active steps to protect their applications, data, and access controls." (Source 3.2)

"The following areas are customer responsibilities as a user of any public cloud: Configuring Identity and Access Management (IAM) to ensure that the contents of your organization are accessed and modifiable by the appropriate personnel... Ensuring you have read all documentation to understand and follow best practices." (Source 3.5)

For Google Cloud, the customer is responsible for: "Managing user permissions and access controls using Cloud IAM... Encrypting sensitive data... Monitoring logs and security events using Cloud Audit Logs and Security Command Center." (Source 3.2)

Option C is incorrect because using PaaS/Managed Services does NOT transfer all security concerns to Google. The customer is still responsible for key areas.

Option B is the most comprehensive and correct answer as it immediately introduces the foundational concept (Shared Responsibility Model) and focuses on the most critical customer responsibilities: IAM (access controls), data procedures (upload/download), and monitoring logs (detective controls), all of which fall squarely under the customer's purview for a managed service.

"You might have situations where you want to permanently destroy data encrypted with CMEK. To do this, you destroy the customer-managed encryption key version. You can't destroy the keyring or key, but you can destroy key versions of the key."

To ensure that your organization’s record data is retained for at least seven years in Cloud Storage, you need to apply a retention policy and enable bucket lock. This prevents the policy from being altered or the data from being deleted before the retention period ends.

Identify Buckets: Determine which Cloud Storage buckets contain the record data that needs to be retained.

Apply Retention Policy:

Go to the Google Cloud Console and navigate to "Cloud Storage".

Select the bucket you identified.

Go to the "Retention" tab and set a retention policy to retain objects for seven years.

Enable Bucket Lock:

Once the retention policy is set, you need to lock the bucket to make the retention policy permanent.

This is done by enabling the bucket lock. Go to the "Retention" tab and click "Lock".

Confirm and Monitor:

Confirm that the bucket lock is applied.

Monitor the bucket using log-based alerts to ensure compliance.

Titan Security Keys are a physical form of two-step verification (2SV) that provide the highest level of account security by using cryptographic signatures to verify the user and the URL of the login page.

Cryptographic Security: Titan Security Keys use a hardware-based cryptographic method to authenticate users, which is resistant to phishing attacks. This ensures that the authentication process is secure and not susceptible to being intercepted or spoofed.

URL Verification: Titan Security Keys verify the URL of the login page during the authentication process, providing an additional layer of security against phishing attempts that may try to redirect users to malicious websites.

Ease of Use: These keys are easy to use and integrate with Google's 2SV process, providing a seamless and highly secure authentication method for users.
