Exam AZ-304 topic 5 question 21 discussion

Correct

Correct Answer: B. Batch works well with intrinsically parallel (also known as "embarrassingly parallel") workloads. Intrinsically parallel workloads are those where the applications can run independently, and each instance completes part of the work. When the applications are executing, they might access some common data, but they do not communicate with other instances of the application. Intrinsically parallel workloads can therefore run at a large scale, determined by the amount of compute resources available to run applications simultaneously. As per the link similar scenario-Manage the cost and size of the pool by using !**** low-priority VMs ****! or automatically scaling the number of nodes as the workload changes. https://docs.microsoft.com/en-us/azure/batch/batch-technical-overview Answer C is incorrect. Azure batch is required, which includes MPI; However, the solution is asking and includes "Minimize costs", which makes utilizing "low-priority VM's" the answer to the specific question: https://docs.microsoft.com/en-us/azure/batch/batch-low-pri-vms

Azure batch is required, which includes MPI; However, the solution is asking and includes "Minimize costs", which makes utilizing "low-priority VM's" the answer to the specific question: https://docs.microsoft.com/en-us/azure/batch/batch-low-pri-vms

Yes you need to lower costs but can you trade off the time you have to wait with low priority vm to do your financial risk modelling, if yes then answer for you will be B, if you would need your model available on the spot then answer for you will be C

Answer is Correct Low-priority VMs make new types of Batch workloads possible by enabling a large amount of compute power to be used for a very low cost. https://docs.microsoft.com/en-us/azure/batch/batch-low-pri-vms

I think the answer is C Message Passing Interface (MPI) is a protocol for communication between computers as they run complex HPC tasks in parallel. To use it, your developers must use an implementation of the protocol, which is usually a library of routines in a .dll. RDMA can give a significant boost to the performance of MPI applications.

doesn't make sense
