Your company has a project in Azure DevOps. The project contains a build pipeline named test-pipeline1 that builds an application named test-app1. You have deployed an agent pool named test-pool that contains a Windows Server 2019 self-hosted agent. The pipeline currently uses test-pool. You have to create another project that would have another build pipeline named test-pipeline1. That pipeline would build another application named test-app2. 
Both test-app1 and test-app2 have conflicting dependencies. You have to minimize the possibility of the two build pipelines from conflicting with each other. You also have to minimize infrastructure costs. Which of the following would you implement for this purpose?

Answer options:

A.Go ahead and create two container jobs.
B.Install the self-hosted agent on a Red Hat Enterprise Linux server.
C.Add another self-hosted agent.
D.Add a new Docker Compose task to build the pipelines.

Answer – A 
To save on costs and run applications with conflicting dependencies, you can actually run your applications in containers. 
You can run the jobs as containers on the virtual machine. This will ensure that each application can run in isolation and there are no conflicts when it comes to dependencies. 
Options B and C are incorrect since these would add to the infrastructure costs. 
Option D is incorrect since this is used to build, push or run multi-container Docker applications.
