Microsoft Certified: Azure Administrator AssociateDeploy and manage Azure compute resourcesEasy
You are deploying an Azure Virtual Machine (VM) that will run a specialized scientific computing application. This application requires specific hardware configurations, including a particular GPU model, which is only available in certain VM sizes. You need to ensure that the VM is deployed with this exact hardware to guarantee application compatibility and performance. Which aspect of VM deployment should you pay close attention to?
- ANetwork Security Group (NSG) Rules
- BAvailability Set Configuration
- CVM Size
- DOperating System Disk Type
Show answer & explanationAnswer & explanation
Correct answer: C. VM Size
The VM size directly determines the number of vCPUs, memory, and available GPU models. Selecting the correct VM size is crucial for specialized applications requiring specific hardware configurations like a particular GPU.
Why the other options are wrong
- A. Network Security Group (NSG) rules control inbound and outbound network traffic, unrelated to the VM's internal hardware configuration.
- B. Availability Set Configuration ensures high availability by distributing VMs across fault and update domains, but it does not dictate the VM's hardware specifications.
- D. Operating System Disk Type affects disk performance (IOPS/throughput) but not the CPU, memory, or GPU hardware.
Azure VM Size
A specification that defines the amount of CPU, memory, storage, and optional GPU resources available to an Azure Virtual Machine.
- Determines the hardware capabilities of the VM.
- Different series (e.g., D, E, N) are optimized for various workloads.
- Crucial for performance, cost, and application compatibility.
Memory trick: To get the right hardware, check the VM's 'size' label.
