AZ-801 Question #108: Real Exam Question with Answer & Explanation

Question

You have an Azure subscription. The subscription contains a virtual machine named VM1 that runs Windows Server. The subscription contains the storage accounts shown in the following table. You plan to enable boot diagnostics for VM1. You need to configure storage for the boot diagnostics logs and snapshots. Which storage account should you use?

Options

• Astorage1
• Bstorage2
• Cstorage3
• Dstorage4

Explanation

For Azure VM boot diagnostics, the storage account must be a general-purpose storage account (StorageV2 or StorageV1) and must support blobs, making Standard_LRS (StorageV2) a suitable choice.

Common mistakes.

• B. Storage2 is a FileStorage account, designed specifically for Azure Files, and is not suitable for boot diagnostics, which require blob storage.
• C. Storage3 is a BlockBlobStorage account, optimized for block blobs, which is not directly supported or recommended for the general purpose blob storage required by boot diagnostics.
• D. Storage4 is a StorageV2 account that explicitly specifies Page Blob Storage, which is primarily used for VHDs and specialized scenarios, not the general-purpose blob storage required by boot diagnostics.
