[All Professional Cloud Architect Questions]

A production database virtual machine on Google Compute Engine has an ext4-formatted persistent disk for data files The database is about to run out of storage space How can you remediate the problem with the least amount of downtime?

AIn the Cloud Platform Console, increase the size of the persistent disk and use the resize2fs command in Linux.

BShut down the virtual machine, use the Cloud Platform Console to increase the persistent disk size, then restart the virtual machine.

CIn the Cloud Platform Console, increase the size of the persistent disk and verify the new space is ready to use with the fdisk command in Linux.

DIn the Cloud Platform Console, create a new persistent disk attached to the virtual machine, format and mount it, and configure the database service to move the files to the new disk.

EIn the Cloud Platform Console, create a snapshot of the persistent disk, restore the snapshot to a new larger disk, unmount the old disk, mount the new disk, and restart the database service.

Show Suggested Answer

Suggested Answer: A

When an application becomes slow, the first step you should take is to gather information about the underlying cause of the problem. One way to do this is by inspecting the logs and metrics from the instances where the application is deployed. Google Cloud Platform (GCP) provides tools such as Cloud Logging and Cloud Monitoring that can help you to collect and analyze this information. By reviewing the logs and metrics from the instances, you may be able to identify issues such as resource shortages (e.g. CPU, memory, or disk), network problems, or application errors that are causing the performance issues. Once you have identified the underlying cause of the problem, you can take steps to resolve it.

Wait, E involves a lot of steps! Is that really the best option?

D sounds complicated, why not just resize the existing disk?

C seems unnecessary, fdisk isn't needed for just resizing.

I think B is safer, though. Better to shut it down first.

I recall that using fdisk is more about partitioning, so I’m leaning towards option A, but I’m not entirely sure if that’s the best approach for minimizing downtime.

I practiced a similar question where we had to consider downtime, and I feel like option B might be too disruptive since it requires shutting down the VM.

I think option A sounds right since it mentions using resize2fs, but I’m not confident about the least downtime part.

I remember that increasing the disk size in the Cloud Console is usually a quick fix, but I'm not sure if I need to shut down the VM first.

I'm leaning towards option E. Taking a snapshot and restoring to a larger disk seems like a good way to avoid downtime and ensure the data is migrated properly. I'll need to double-check the steps, but this seems like the safest and most straightforward option.

Option D seems like the most comprehensive solution to me. Creating a new disk, moving the data, and reconfiguring the database service would ensure I don't run into any issues with the resizing. It might take a bit more time, but it's probably the most reliable approach.

This looks like a straightforward question about increasing storage space for a database. I think option A is the best approach - it allows me to resize the disk without having to shut down the VM, which would minimize downtime.

Hmm, I'm a bit unsure about this one. I'm not familiar with the resize2fs command, so I'm not sure if that's the best way to go. Option B seems safer, even though it requires a restart. I'll have to look into the different commands and approaches more closely.

I'm confident that option A, Skills-based Routing, is the best solution here. It allows us to route cases based on the agent's language and knowledge, which is exactly what the question is asking for.

Ah yes, denormalization - that's the term I was looking for. Rejoining relations makes sense as the opposite of normalization. I feel confident about this one.

Option E with the snapshot sounds like a good idea, but it might take a bit longer to execute. Still, better safe than sorry when it comes to production databases.

Haha, Option B is like the IT version of 'have you tried turning it off and on again?' Gotta love the classic reboot approach.

I'm leaning towards Option D. Creating a new disk and migrating the data seems like a more robust solution in case the resize operation goes wrong.

Option A seems like the easiest and quickest way to add more storage space without having to shut down the VM. The resize2fs command should do the trick.
