12. Which of the following is true about the Cloud Services feature? (Choose all that apply.)
Correct Answers :
[C]
Explanation :
- A. Incorrect: When you create a new cloud service project, you can choose to add web or worker roles from the provided role templates, or you can create an empty cloud service (no roles) and later add the desired roles to the project using either new role templates or by adding existing projects as roles.
- B. Incorrect: Any role template is merely a starting point for creating a role implementation. The Service Bus Queue template includes code to follow a queue but still requires customization and configuration for your specific requirements. Likewise, you could manually write the same code for a worker role you implement from scratch.
- C. Correct: By default, the RoleEntryPoint does nothing. To create a worker role with any functionality you have to provide custom code in the Run() override. Optionally, you also override OnStart() and OnStop() to provide functionality that runs before the role receives requests and cleans up before the role shuts down or recycles.
- D. Incorrect: Your existing web.config settings work as expected with your web roles while running both locally and in the cloud. The reason for using the role configuration settings is to surface those settings to the management portal for editing without having to redeploy.
