Google Cloud Associate Cloud Engineer — Question 262

You need to deploy a third-party software application onto a single Compute Engine VM instance. The application requires the highest speed read and write disk access for the internal database. You need to ensure the instance will recover on failure. What should you do?

Answer options

• A. Create an instance template. Set the disk type to be an SSD Persistent Disk. Launch the instance template as part of a stateful managed instance group.
• B. Create an instance template. Set the disk type to be an SSD Persistent Disk. Launch the instance template as part of a stateless managed instance group.
• C. Create an instance template. Set the disk type to be Hyperdisk Extreme. Launch the instance template as part of a stateful managed instance group.
• D. Create an instance template. Set the disk type to be Hyperdisk Extreme. Launch the instance template as part of a stateless managed instance group.

Correct answer: C

Explanation

The correct answer is C because using Hyperdisk Extreme provides the highest performance disk access required for the internal database, and launching it as part of a stateful managed instance group ensures recovery on failure. The other options either use SSD Persistent Disk, which does not meet the performance requirement, or are part of a stateless managed instance group, which does not provide the necessary instance recovery.
