Google Cloud Professional Cloud Security Engineer Practice Exam

Which service is best for managing symmetric encryption keys for Cloud Dataproc persistent disks?

1. Cloud Security Scanner

2. Cloud Dataproc itself

3. Cloud Key Management Service (KMS)

4. Cloud Functions

The correct answer is: Cloud Key Management Service (KMS)

The best service for managing symmetric encryption keys for Cloud Dataproc persistent disks is Cloud Key Management Service (KMS). This service is specifically designed to help users create, manage, and control encryption keys used for their data, including those stored in Google Cloud services. Cloud KMS provides a centralized way to handle cryptographic keys, ensuring that they are securely stored and easily accessible for services that require encryption, such as Cloud Dataproc. When managing encryption keys, it is important to have a secure solution that integrates seamlessly with other cloud services. Cloud KMS supports various cryptographic algorithms, provides auditing capabilities, and enables fine-grained access controls, ensuring that only authorized users and services can access or manage the keys. This is crucial for maintaining the security of sensitive data and complying with security and privacy regulations. In contrast, other options listed do not cater specifically to key management. While Cloud Dataproc can handle data processing, it does not inherently provide a key management solution. Cloud Security Scanner focuses on identifying vulnerabilities in applications, rather than managing encryption keys. Cloud Functions is a serverless execution environment that allows for running code in response to events but is not designed for key management tasks. Therefore, Cloud KMS stands out as the most appropriate service
