Question 1

You are designing a compute architecture for a batch processing workload.

The workload requires 50 virtual machines to process data from a queue. The processing is fault-tolerant; if a VM is terminated mid-process, the message returns to the queue and another VM picks it up. You need to design the most cost-effective compute solution possible.

Which compute option should you recommend?

Accepted Answer

Keywords: 'fault-tolerant', 'can be terminated', 'most cost-effective'. This is the textbook definition for Azure Spot VMs.

Question 2

What mistakes do candidates make on this AZ-305 question?

Accepted Answer

Choosing Reserved Instances. While RIs save money, they require a 1 or 3-year commitment and are meant for always-on workloads. Spot is cheaper and better for interruptible batch jobs.
