[All Professional Cloud Architect Questions]

Your company has an enterprise application running on Compute Engine that requires high availability and high performance. The application has been deployed on two instances in two zones in the same region m active passive mode. The application writes data to a persistent disk in the case of a single zone outage that data should be immediately made available to the other instance in the other zone. You want to maximize performance while minimizing downtime and data loss. What should you do?

A1. Attach a persistent SSD disk to the first instance
2. Create a snapshot every hour
3. In case of a zone outage, recreate a persistent SSD disk in the second instance where data is coming from the created snapshot

B1 Create a Cloud Storage bucket
2. Mount the bucket into the first instance with gcs-fuse
3. In case of a zone outage, mount the Cloud Storage bucket to the second instance with gcs-fuse

C1 Attach a local SSD lo the first instance disk
2. Execute an rsync command every hour where the target is a persistent SSD disk attached to the second instance
3. In case of a zone outage, use the second instance

D1. Attach a regional SSD persistent Ask to the first instance
2. In case of a zone outage, force-attach the disk to the other instance

I prefer option B because using Cloud Storage bucket with gcs-fuse can provide better performance.

Option D is definitely the way to go. Attaching a regional persistent disk is the best way to ensure high availability and minimize downtime. It's a no-brainer!

It makes sense to have a solution that can quickly switch over to another instance in case of a zone outage. Option D seems like the most reliable option.

Haha, did anyone else notice the typo in the question? It says 'lo' instead of 'to' in option C. Gotta love these certification exams, always keeping us on our toes!

Option B with the Cloud Storage bucket is an interesting idea, but I'm not sure it would provide the same level of performance as the regional persistent disk.

I agree with Phung. The regional persistent disk is the way to go. It's the most straightforward solution to maximize performance and minimize data loss.

Option D seems like the best choice here. Attaching a regional persistent disk ensures high availability and minimal downtime in the event of a zone outage.
