Difficulty: HardCompute Virtualization Solutions

A digital media broadcasting company is designing an Azure compute infrastructure for two new workloads:
- Workload 1: A video rendering system that processes non-urgent, interruptible background encoding tasks. The primary goal is to minimize compute costs, even if virtual machines are evicted during processing.
- Workload 2: A core licensing service that processes cryptographic keys, handles highly sensitive user data, requires physical isolation at the hardware level due to regulatory compliance, and must run continuously with a 99.99% availability SLA.

Which two compute virtualization solutions should you recommend to meet the requirements for these workloads? (Select two.)

  1. Azure Spot Virtual Machines for Workload 1Answer
  2. Azure Dedicated Hosts for Workload 2Answer
  3. C
    Azure Spot Virtual Machines for Workload 2
  4. D
    Azure Functions on a Consumption plan for Workload 1
  5. E
    A single-zone Virtual Machine Scale Set for Workload 2

Answer

Azure Spot Virtual Machines for Workload 1 and Azure Dedicated Hosts for Workload 2
Azure Spot Virtual Machines are correct for the video rendering workload because they allow the customer to take advantage of unused Azure capacity at significant cost savings, which is ideal for workloads that are non-urgent and can be interrupted. Azure Dedicated Hosts are correct for the licensing service because they provide physical servers dedicated to a single Azure subscription, satisfying the physical isolation requirement, and support zone-redundant deployments to meet the 99.99% SLA.

Step-by-Step Solution

1
Analyze the requirements for Workload 1.
Identify that the workload consists of background, non-urgent, interruptible tasks where minimizing cost is the primary goal.
This establishes that the workload is suitable for transient compute models.
2
Evaluate compute solutions for Workload 1.
Determine that Azure Spot Virtual Machines offer the lowest cost for workloads that can tolerate eviction.
This matches the low-cost and interruptible nature of the video rendering jobs.
3
Analyze the requirements for Workload 2.
Identify that the workload requires physical hardware isolation for regulatory compliance and a 99.99% availability SLA.
This dictates the need for non-shared physical infrastructure and high-availability design.
4
Evaluate compute solutions for Workload 2.
Determine that Azure Dedicated Hosts provide physical isolation at the host level and can be placed across multiple availability zones to meet the 99.99% SLA.
This fully addresses the compliance and availability constraints.
