How many Update Domains (UDs) and Fault Domains (FDs) should you create?
/ Interview Question Microsoft Azure • ARM Virtual Machines 70-532 & 70-533 / by admin / Leave a comment
A company has an Azure subscription with four virtual machines (VM) that are provisioned in an availability set. The VMs support an existing web service. The company expects additional demand for the web service. You add 10 new VMs to the environment.
You need to configure the environment. How many Update Domains (UDs) and Fault Domains (FDs) should you create?
A. 2 UDs and 5 FDs
B. 5 UDs and 2 FDs
C. 14 UDs and 2 FDs
D. 14 UDs and 14 FDs
Answer: B Explanations:
In Cloud Services, you can set the number of update domains in the service model’s .csdef file. By default its set to 5 but you can increase that to a maximum of 20. However, the .csdef is only used for Cloud Services, not for VMs. So regardless of what you set or even how you try to do it, Azure VM UDs come in groups of 5. With 14 VMs, that means you’ll have 5 UDs. UD0 – to – UD4.
