Answer 1

API Management (APIM) is an Azure Service that allows organizations to publish and manage APIs and gives consumers a ways to discover and consume the APIs.

It consists of a gateway that provides a way to expose existing back-end services to external and internal consumers.

An Azure portal that allows administrators to define the API schema, set policies that govern the use to the API and manage users.

A developer portal which provides all the resources a developer would need to consume the API such as API documentation and API keys.

Policies allow the administrator to change the behavior of the APIs based on certain conditions. For instance policies allow organizations to limit the rate of API calls per consumer. Or route traffic to an API in a specific region.

What is a private endpoint?

Answer 5

A private endpoint is a network interface that uses a private IP address from your virtual network. This network interface connects you privately and securely to a service that’s powered by Azure Private Link. By enabling a private endpoint, you’re bringing the service into your virtual network.

A private-link resource is the destination target of a specified private endpoint. i.e. Azure Cosmos DB, Azure SQL, Azure Storage.
