What does Google Cloud's shared responsibility model mean for customers using managed services?

Correct answer: Google manages infrastructure security while customers manage data and access

Option A is correct because under Google Cloud's shared responsibility model for managed services, Google takes responsibility for securing the underlying infrastructure, including physical hardware, networking, and the managed service platform, while customers retain responsibility for their data, identity and access management, and application-level configurations. Option B is incorrect because hardware patching is handled entirely by Google when customers use managed services; customers never have access to or responsibility for the physical hardware. Option C is incorrect because physical data center security is Google's exclusive responsibility across all service models. Option D is incorrect because some security responsibilities, particularly around data classification, access control, and IAM policy configuration, always remain with the customer.
