Exam Professional Cloud Architect topic 1 question 14 discussion

A is the correct answer because the question says "with minimum downtime"

least amount of downtime? is the sugar word. You miss that you miss all. Everything there is correct but I believe its only A that fits that requirement

1. Online Resizing: Google Cloud Platform allows you to increase the size of a persistent disk while it's attached to a running VM. This means you don't need to shut down the database server. 2. resize2fs: This Linux command extends the file system to utilize the newly added space on the disk. It can be run while the file system is mounted, minimizing downtime.

A) can not work becouse you must extend partition and after than you can extend filesystem C) ok becouse you can use fdisk in linux to extend partition and after than you can resize ext4 filesystem

A is the right answer.You should resize the disk, take a snapshot, then resize the filesystem and partitions (eg.) ext4, xfs etc.

Unlike Azure, in google you can dynamically resize the persistent disk while VM is running. This narrows down the option to A or C. Since the question says "ext4-formatted persistent disk", we need to choose correct command (resize2fs or fdisk ) for Linux for resizing ext4 file format disk. To resize an ext4 file system in Linux, you can use the resize2fs command. FDISK to manipulate partition tables in Linux.

According to the right url, A is the right answer. https://cloud.google.com/compute/docs/disks/resize-persistent-disk

The right URL for the oficial document is, https://cloud.google.com/compute/docs/disks/resize-persistent-disk

A is no brainer

E is the correct because is true you need minimum downtime but in Production a backup is a must.

E because you are in Production, and you need a backup

A is correct, resize disk don't required reboot or downtime https://cloud.google.com/compute/docs/disks/resize-persistent-disk

A: Increasing the size of the persistent disk in the Cloud Platform Console and using the resize2fs command in Linux. Increasing the size of the persistent disk can be done without requiring the virtual machine to be shut down, and the resize2fs command can be used to resize the ext4 filesystem on the disk to take advantage of the additional space. This will allow you to add more storage space to the virtual machine without disrupting the database service.

A is ok

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

A resize the disk standard command
