Exam AZ-304 topic 5 question 34 discussion

Actual exam question from Microsoft's AZ-304

Question #: 34
Topic #: 5

You architect a solution that calculates 3D geometry from height-map data.
You have the following requirements:
Perform calculations in Azure.

✑ Each node must communicate data to every other node.
✑ Maximize the number of nodes to calculate multiple scenes as fast as possible.
✑ Require the least amount of effort to implement.
You need to recommend a solution.
Which two actions should you recommend? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

A. Create a render farm that uses Azure Batch.
B. Create a render farm that uses virtual machines (VMs).
C. Enable parallel task execution on compute nodes.
D. Create a render farm that uses virtual machine (VM) scale sets.
E. Enable parallel file systems on Azure.

Correct. These are all features of Azure Batch https://docs.microsoft.com/en-us/azure/batch/batch-technical-overview

That's right. Thanks for the link. At first I thought that in batch the nodes can't communicate with each other. But the page you share states that it is possible. They are called "tightly coupled workloads".

from your link: "Batch works well with intrinsically parallel (also known as "embarrassingly parallel") workloads. These workloads have applications which can run independently, with each instance completing part of the work. When the applications are executing, they might access some common data, but they don't communicate with other instances of the application". they dont' comminicate with other instances. Should it remove the A option?

yes but this is another thing. In addition to use Azure Batch you can enable parallel task execution on each node (or VM) in the pool defined. So provided answers are correct. For more info you can look the following references: https://docs.microsoft.com/en-us/azure/architecture/example-scenario/infrastructure/video-rendering https://docs.microsoft.com/en-us/azure/batch/batch-parallel-node-tasks#enable-parallel-task-execution

"calculates 3D geometry" so use Batch (https://docs.microsoft.com/en-us/azure/batch/batch-technical-overview) "as fast as possible" so parallel execution A and C are the answers
