You are writing code to create and run an Azure Batch job.

You have created a pool of compute nodes.

You need to choose the right class and its method to submit a batch job to the Batch service.

Which method should you use?

A. JobOperations.EnableJobAsync(String, IEnumerable,CancellationToken)
B. JobOperations.CreateJob()
C. CloudJob.Enable(IEnumerable)
D. JobOperations.EnableJob(String,IEnumerable)

E. CloudJob.CommitAsync(IEnumerable, CancellationToken)

Explanation:
A Batch job is a logical grouping of one or more tasks. A job includes settings common to the tasks, such as priority and the pool to run tasks on. The app uses the BatchClient.JobOperations.CreateJob method to create a job on your pool.

The Commit method submits the job to the Batch service. Initially the job has no tasks.

{
CloudJob job = batchClient.JobOperations.CreateJob();
job.Id = JobId;
job.PoolInformation = new PoolInformation { PoolId = PoolId };

job.Commit();
}
