[All AZ-204 Questions]

HOTSPOT -

You are building a software-as-a-service (SaaS) application that analyzes DNA data that will run on Azure virtual machines (VMs) in an availability zone. The data is stored on managed disks attached to the VM. The performance of the analysis is determined by the speed of the disk attached to the VM.

You have the following requirements:

• The application must be able to quickly revert to the previous day’s data if a systemic error is detected.
• The application must minimize downtime in the case of an Azure datacenter outage.

You need to provision the managed disk for the VM to maximize performance while meeting the requirements.

Which type of Azure Managed Disk should you use? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

Wrong answer: Managed disk doesn't support GRS Ans: Premium SSD and ZRS They are asking for high performance workloads which is supported by Premium tier https://learn.microsoft.com/en-us/azure/virtual-machines/disks-types Also they are asking for zone redundancy (if datacenter goes down, NOT region outage). Also managed disk doesn't support GRS https://learn.microsoft.com/en-us/azure/virtual-machines/disks-redundancy

Azure Disk Backup supports multiple types of Managed Disks, including Standard HDD, Standard SSD, and Premium SSD1. However, Premium SSDs are often preferred for their superior performance and reliability, which is crucial for your DNA analysis application.

I agree, too. Azure managed disk doesn’t have GRS redundancy option. GRS is a option of azure storage. But this question request use azure managed disk.

Azure managed disks offer two storage redundancy options, zone-redundant storage (ZRS), and locally-redundant storage. Ans: Premium SSD and ZRS https://learn.microsoft.com/en-us/azure/virtual-machines/disks-redundancy

Ans: Premium SSD and ZRS Ref: https://learn.microsoft.com/en-us/azure/virtual-machines/disks-redundancy "Azure managed disks offer two storage redundancy options, zone-redundant storage (ZRS), and locally redundant storage. ZRS provides higher availability for managed disks than locally redundant storage (LRS) does. However, the write latency for LRS disks is better than ZRS disks because LRS disks synchronously write data to three copies in a single data center."

WHEN THEY SAY 'Azure datacenter outage' they are implying a data center within a region which is hosted in one of the region's three zones. That alone gives it away that its ZRS with P-SSD.

Premium SSD and Zone-Redundant storage ZRS Because Azure managed disks offer two storage redundancy options, zone-redundant storage and locally-redundan storage. ZRS provider higher availability for managed disks than LRS.

Maybe I am getting confused by the wording here, but doesn't 'Azure datacenter outage' mean the region is out, and thus you need GRS?

From: https://learn.microsoft.com/en-us/azure/architecture/resiliency/recovery-loss-azure-region Azure is divided physically and logically into units called regions. A region consists of one or more data centers in close proximity. Many regions and services also support availability zones, which can be used to provide more resiliency against outages in a single data center. Consider using regions with availability zones to improve the availability of your solution. *** So, zones for outage in a datacenter.
