Which capability do persistent volumes provide to containerized applications?
Persistent volumes provide the capability to retain application state and data for containerized applications. Unlike ephemeral storage, which is temporary and tied to the lifecycle of a container, persistent volumes ensure that data is preserved across pod restarts and re-deployments. This retention is crucial for applications that need to maintain state, such as databases and stateful services.

D. Retention of application state and data

D. Persistent volumes are defined by a PVC (Persistent Volume Claim) in a manifest file which is for maintaining state if a container is lost
Of course it's D) A. Automated disk archival - Persistent disks have nothing to do with archiving data B. Support for in-memory databases - What does disk storage have to do with memory? These aren't pagefiles. C. Support for ephemeral workloads - Ephemeral workloads are, well, ephemeral and thus don't need persistent storage D. Retention of application state and data - Obviously the correct answer. What I want to know is how the official Examtopics answer for this could be so wrong!
Correct answer is D
