Subtask 3.1: Security DesignSecurityEncryptionCloud KMSCMEK

GCP PCA · Question 48 · Security Design

Your organization is migrating sensitive data to Cloud Storage. The security team dictates that Google must not manage the encryption keys, but they also do not want the operational burden of maintaining their own highly available key servers on-premises. Which TWO actions should you take? (Select TWO)

Answer options:

A.

Use Customer-Managed Encryption Keys (CMEK)

B.

Use Customer-Supplied Encryption Keys (CSEK)

C.

Create a Key Ring and Key in Cloud KMS

D.

Use Google-Managed Encryption Keys (GMEK)

E.

Encrypt the data locally using a Python script before uploading

How to approach this question

Identify the encryption method that provides control without infrastructure overhead.

Full Answer

Customer-Managed Encryption Keys (CMEK) strike the balance between control and operational overhead. The keys are generated and stored in Google's Cloud Key Management Service (Cloud KMS), so Google handles the high availability. However, the customer retains full cryptographic control over the keys.

Common mistakes

Choosing CSEK (B), which forces the customer to build their own key servers.
