Microsoft Azure Architect Technologies (2020, legacy) — Question 73

A company plans to use third-party application software to perform complex data analysis processes. The software will use up to 500 identical virtual machines
(VMs) based on an Azure Marketplace VM image.
You need to design the infrastructure for the third-party application server. The solution must meet the following requirements:
✑ The number of VMs that are running at any given point in time must change when the user workload changes.
✑ When a new version of the application is available in Azure Marketplace it must be deployed without causing application downtime.
✑ Use VM scale sets.
✑ Minimize the need for ongoing maintenance.
Which two technologies should you recommend? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

Answer options

Correct answer: B, D

Explanation

The correct technologies are autoscale (B) and managed disks (D). Autoscale allows the number of VMs to automatically adjust based on workload, meeting the requirement for dynamic scaling. Managed disks provide a more simplified management experience and help ensure that the VMs can be updated without downtime, satisfying the maintenance and deployment needs. The other options, a single storage account (A) and a single placement group (C), do not directly address the requirements of scaling or minimizing maintenance.
