You want to use Azure Notification Hubs to deliver notifications from a cloud web service to a mobile app. You want to be able to send notifications to both the production version of the app and the development version of the app.
You need to determine the number of hubs, namespaces, and access policies to create.
Select correct placeholder values.
How many namespaces should you create? Answer: Placeholder 1
How many hubs should you create? Answer: Placeholder 2
How many access policies should you create? Answer: Placeholder 3
You should create one namespace. Namespaces should have one-to-one mappings with apps. In this scenario, there is only one app, so you should create one namespace.
You should create two hubs. Hubs should have one-to-one mappings with different versions or implementations of apps. In this scenario, there is a production version and a development version. Therefore, you should create two hubs.
You should create one access policy. An access policy represents the connection string and access key for an Azure resource. The cloud web service uses the access policy to access the resource, which in this case is Notification Hubs.
