Answer: Mount a Local SSD volume as the backup location. After the backup is complete, use gsutil to move the backup to Google Cloud Storage.
The correct answer is B. Mounting a Local SSD volume as the backup location ensures high performance and minimal impact on disk performance due to the SSD's high I/O capabilities and low latency. This method aligns with the requirement for the backup activity to complete as quickly as possible. After the backup is finalized, using gsutil to move the backup to Google Cloud Storage provides a reliable and secure offsite storage solution, ensuring data durability. Although Local SSDs are ephemeral and are deleted when the instance is stopped or deleted, they serve well for staging backups before transferring them to more permanent storage like Google Cloud Storage.

Your company operates several databases within a single MySQL instance on Google Cloud Platform (GCP). To ensure data reliability and disaster recovery, you need to take regular backups of a specific database. These backups must complete as quickly as possible to minimize downtime and cannot negatively impact ongoing disk performance. Considering the requirement to balance backup speed and system performance, how should you configure the storage for these backups?
A
Configure a cron job to use the gcloud tool to take regular backups using persistent disk snapshots.
B
Mount a Local SSD volume as the backup location. After the backup is complete, use gsutil to move the backup to Google Cloud Storage.
C
Use gcsfuse to mount a Google Cloud Storage bucket as a volume directly on the instance and write backups to the mounted location using mysqldump.
D
Mount additional persistent disk volumes onto each virtual machine (VM) instance in a RAID10 array and use LVM to create snapshots to send to Cloud Storage.
