AZ-305 Question #168: Real Exam Question with Answer & Explanation

Question

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.

Options

• ACreate a render farm that uses Azure Batch.
• BEnable parallel file systems on Azure.
• CEnable parallel task execution on compute nodes.
• DCreate a render farm that uses virtual machine (VM) scale sets.
• ECreate a render farm that uses virtual machines (VMs).

Explanation

To perform 3D geometry calculations in Azure with maximum node scalability, all-to-all node communication, and minimal implementation effort, the solution involves using Azure Batch for the render farm and enabling parallel task execution on compute nodes.

Common mistakes.

• B. While parallel file systems can improve data access for HPC, they are not the primary solution for the computational processing and direct inter-node communication requirements of the calculation itself.
