"“Cloud Storage FUSE is an open source [FUSE](http://fuse.sourceforge.net/) adapter that allows you to mount Cloud Storage buckets as file systems on Linux or macOS systems. It also provides a way for applications to upload and download Cloud Storage objects using standard file system semantics. Cloud Storage FUSE can be run anywhere with connectivity to Cloud Storage, including Google Compute Engine VMs or on-premises systems[**1**](https://cloud.google.com/storage/docs/gcs-fuse#f1-note)." D says "gcsfuse", should be D

directly from the documentation of gcs fuse > While Cloud Storage FUSE has a file system interface, it is not like an NFS or CIFS file system on the backend. Additionally, Cloud Storage FUSE is not POSIX compliant. For a POSIX file system product in Google Cloud, see Filestore.

IMHO d) is wrong, the correct answer is c). The requirement is explicitly POSIX filesystem - using gcsfuse Cloud Storage still remains an object storage - IMHO gcsfuse brings a lot of downsizes compared with Filestore and in the question there are no indications that a non-POSIX filesystem shall be used.

Answer is C As filestore can be attached to multiple pods/vm in R/W mode A & B are wrong for the same reason, PD can be attached to single pod for write operation.

C 1. "each Instance needs to read and wrlte to the same POSIX filesystem" 2. Cloud Storage is not POSIX compliant filesystem but Object Storage and gcsfuse only "simulates" file system 3.

C Explanation: A & B: persistent disk won't be shared. Question says "each instance needs to read and write to the same POSIX filesystem." Although, now u can share persistent disk(https://cloud.google.com/compute/docs/disks/sharing-disks-between-vms#:~:text=Note%3A%20You%20can%20share%20Persistent%20Disk%20volumes%20only%20with%20VMs%20that%20are%20in%20the%20same%20zone%20as%20the%20disk.) but question doesnt mention that all VMs are in same zone as disk. C: Filestore ideal for NFS and POSIX D: shared access can be achieved using GCSFuse, still, it's not POSIX complaint (https://cloud.google.com/storage/docs/gcs-fuse#differences-and-limitations)
