Answer: Store the application data on a regional persistent disk. Establish a routine for capturing snapshots of this disk. In case of an outage, generate a new disk using the most recent snapshot and link it to a fresh virtual machine situated in another zone.
Option A is correct because it suggests storing the application data on a regional persistent disk, ensuring high availability by distributing the data across multiple zones within a region. Creating a snapshot schedule allows for backups, and in the event of a zonal failure, a new disk can be created from the most recent snapshot and attached to a new VM in another zone, minimizing downtime. Options B and D are incorrect as they rely on zonal persistent disks, which do not guarantee immediate availability during a zonal failure. Option C, while using a regional disk, does not utilize snapshots for immediate recovery, potentially leading to downtime.

To ensure high availability for a globally accessed news website on Google Cloud, especially to withstand a zonal failure, which strategy should you implement?
A
Store the application data on a regional persistent disk. Establish a routine for capturing snapshots of this disk. In case of an outage, generate a new disk using the most recent snapshot and link it to a fresh virtual machine situated in another zone.
B
Place the application data onto a persistent disk within a specific zone. Establish a schedule for taking snapshots of the disk. In the event of an outage, generate a fresh disk from the latest snapshot and connect it to a new virtual machine located in a different zone.
C
Secure the application data on a persistent disk with a regional scope. In the event of an outage, establish a new instance in a different zone and connect this disk to ensure continuity.
D
Store the application data on a dedicated persistent disk associated with a particular zone. Should an outage transpire, set up a new instance in an alternate zone and attach this disk to it.
