Azure Virtual Machines

Question 1

When would I use a Standard SSD?

Answer 1

Moderate performance, suitable for workloads with lower IOPS and throughput

Question 2

When would I use a Premium SSD v2?

Answer 2

Higher performance with IOPS and throughput configurable based on VM size

Question 3

What IOPS has a Premium SSD v2?

Answer 3

IOPS are defined using disk size, IOPS up to 80K

Question 4

What IOPS has a Standard SSD?

Answer 4

IOPS are defined using disk size, IOPS up to 6K

Question 5

I have a single Premium SSD v2 and wnat to increase its IOPS; how can iu do this?

Answer 5

Increase the disk size and the IOPS increase.

Question 6

What latency has Premium SSD v2?

Answer 6

Low latency for consistent performance

Question 7

What latency has Standard SSD?

Answer 7

Moderate latency; may not meet high-performance needs

Question 8

In azure, when you set the disk encryption to Volume Type all, what are you doing?

Answer 8

(This is older thinking, today Azure has hardware based encryption using Server-Side Encryption (SSE) for Managed Disks)
When you set the disk encryption to VolumeType: All in Azure, you are configuring BitLocker to encrypt both the operating system and data volumes of a virtual machine (VM).

Question 9

What is Server-Side Encryption (SSE) for Managed Disks?

Answer 9

Managed Disks in Azure have server-side encryption (SSE) with 256-bit AES encryption, enabled by default. SSE encrypts data at rest automatically without requiring any additional setup, and this includes OS disks, data disks, and temporary disks.

Question 10

Is Azure have server-side encryption (SSE) hardware offloaded?

Answer 10

Yes, Azure offers server-side encryption (SSE) with hardware offloading through its Encryption at Host feature.
This feature ensures that data is encrypted at rest using hardware-based encryption mechanisms, providing end-to-end encryption for your virtual machine (VM) data.

Question 11

What are Azure Confidential Computing?

Question 12

In Azure, can you enable disk encryption for all virtual machines?

Answer 12

Yes,

In Azure, you can enable disk encryption for your virtual machines (VMs) using Azure Disk Encryption (ADE). ADE utilizes BitLocker for Windows VMs and DM-Crypt for Linux VMs to provide full disk encryption for both operating system and data disks. This feature integrates with Azure Key Vault, allowing you to manage and control the encryption keys.

Question 13

For Azure VM Scale Set, how many days of history does n predictive auto-scaling require?

Answer 13

Seven historical days are required, but the most accurate is fifteen days.
