Topic 1 Question 123
You need to deploy a stateful workload on Google Cloud. The workload can scale horizontally, but each instance needs to read and write to the same POSIX filesystem. At high load, the stateful workload needs to support up to 100 MB/s of writes. What should you do?
Use a persistent disk for each instance.
Use a regional persistent disk for each instance.
Create a Cloud Filestore instance and mount it in each instance.
Create a Cloud Storage bucket and mount it in each instance using gcsfuse.

Answer should be C, https://cloud.google.com/storage/docs/gcs-fuse#notes
👍 28TotoroChina2021/07/01IMHO 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.

“Cloud Filestore was easy to provision and mount, and reliable for the kind of workload we have. Having a POSIX file system that we can mount and use directly helps us speed-read our files, especially on new machines. We can also use the normal I/O features of any language and don’t have to use a specific SDK to use an object store."
