You are migrating a production-critical on-premises application that requires 96 vCPUs to perform its task. You want to make sure the application runs in a similar environment on GCP. What should you do?
A.
When creating the VM, use machine type n1-standard-96.
B.
When creating the VM, use Intel Skylake as the CPU platform.
C.
Create the VM using Compute Engine default settings. Use gcloud to modify the running instance to have 96 vCPUs.
D.
Start the VM using Compute Engine default settings, and adjust as you go based on Rightsizing Recommendations.
A. When creating the VM, use machine type n1-standard-96.
Answer A is the correct answer as it directly addresses the requirement to have 96 vCPUs by selecting the n1-standard-96 machine type. This machine type offers 96 vCPUs, 360 GB of memory, and up to 2,400 GB of local SSD storage.

Answer B is incorrect because selecting a CPU platform alone will not guarantee the availability of the required number of vCPUs.
Answer C is incorrect because it is not possible to modify a running Compute Engine instance to add vCPUs. vCPUs can only be added or removed during instance creation or by stopping the instance first.
Answer D is incorrect because while Rightsizing Recommendations can help optimize compute resources, they will not guarantee that the application has the required 96 vCPUs to function properly.

N1 machine series have up to 96 vCPUs, 6.5 GB of memory per vCPU, and are available on Intel Sandy Bridge, Ivy Bridge, Haswell, Broadwell, and Skylake CPU platforms.
