Google Cloud VM

Correct Answer: D.

Option A is Incorrect.

Preemptible VMs are compute instances that are short-lived and are appropriate to be used for batch jobs.

Option B is Incorrect.

Cloud storage for Firebase stores and serves content that is user generated on block storage.

Option C is Incorrect.

Local SSD also offers high performance block storage but is attached locally.

Option D is Correct.

Persistent disk from Google Cloud offers block storage that is reliable and high performance for Virtual Machines.

The correct answer is D. Persistent Disk.

Persistent Disk is a Google Cloud offering for Virtual Machines (VMs) that provides reliable and high-performance block storage. It offers block-level storage that can be attached to a VM, allowing it to persist data even after the VM is terminated.

Persistent Disk offers several features that make it a suitable choice for storing critical data, such as automatic replication of data across multiple physical disks, synchronous replication across zones for high availability, and the ability to take snapshots for backup and recovery purposes. Additionally, it offers consistent performance and low latency for I/O operations, making it ideal for applications that require high-speed data access.

In contrast, Preemptible VMs are a cost-saving option that allows users to run short-lived, fault-tolerant workloads at a lower price. However, they are not suitable for applications that require persistent storage or high availability.

Cloud Storage for Firebase is a cloud-based storage solution designed specifically for mobile and web applications, and it is not intended for use with VMs. It provides a scalable and secure object storage solution for storing and serving user-generated content, such as images, audio, and video files.

Local SSD provides temporary, non-persistent storage that is directly attached to a VM's physical host. It offers high performance for I/O operations but is not suitable for storing critical data since it is not persistent and can be lost if the VM is terminated.
