A. B. C. D. E.

Correct Answer: A and D

Ephemeral OS disks are the disks that are built on the local VM (Virtual Machine) storage.

These disks help you in getting lower write/read latency to the disk and quicker VM reimage.

The main characteristics of Ephemeral OS disks are: Good for stateless apps.

Supported by custom images, Marketplace, and Shared Image Gallery.

Allows faster resetting or reimaging VMs and scaling set instances to actual boot state.

Lower read/write latency.

Availability in all Azure regions.

Option A is correct.

Ephemeral disks are the disks that are built on the local VM(Virtual Machine) storage.

Option B is incorrect.

Ephemeral disks are considered good for stateless applications.

Option C is incorrect.

Ephemeral disk results in lower write/read latency.

Option D is correct.

One of the key features of Ephemeral disks is their availability in all Azure regions.

Option E is incorrect.

All of the given statements are false, only options A and D are correct.

Sure, I can provide you with a detailed explanation of the Ephemeral OS disks in Azure.

Ephemeral OS disks are a type of temporary disk that is created on the local VM storage instead of using Azure Storage. These disks are designed to be used as a temporary scratch disk for applications that require high-speed, temporary storage. They are created and attached to a virtual machine when it starts and are deleted when the virtual machine is stopped or deallocated.

Now let's go through each of the given options to see which statement(s) correctly describe Ephemeral OS disks.

Option A: Ephemeral OS disks are the disks that are built on the local VM(Virtual Machine) storage This statement is true. Ephemeral OS disks are created on the local VM storage and are not persisted when the VM is stopped or deallocated.

Option B: Ephemeral disks are not good for stateless apps. This statement is not entirely true. Ephemeral OS disks are suitable for stateless applications that don't require persistent storage. However, they are not recommended for stateful applications that require persistent storage.

Option C: Ephemeral OS disk results in having higher write/read latency to the disk This statement is also true. Ephemeral OS disks have higher write and read latency compared to disks stored in Azure Storage. This is because Ephemeral disks use the local storage of the virtual machine, which is typically less performant than Azure Storage.

Option D: Ephemeral disks are available in all Azure regions This statement is not true. Ephemeral disks are not available in all Azure regions. They are only available in certain regions and virtual machine sizes.

Therefore, the correct answer to the question is option E, which includes statements A, B, and C.
