D . One App Service Plan

View Answer

Answer: D

Explanation:

In App Service (Web Apps, API Apps, or Mobile Apps), an app always runs in an App Service plan. An App Service plan defines a set of compute resources for a web app to run. One App Service Plan: Correct Choice

For an Azure Web App, you need to have an Azure App Service Plan in place. You can associate multiple Azure Web Apps with the same App Service Plan. Hence to save on costs, you can just have one Azure App Service Plan in place.

An Azure Load Balancer: Incorrect Choice

An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM An Application Gateway: Incorrect Choice

Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications. Traditional load balancers operate at the transport layer (OSI layer 4 – TCP and UDP) and route traffic based on source IP address and port, to a destination IP address and port.

10 Azure App Service Plans: Incorrect Choice

For an Azure Web App, you need to have an Azure App Service Plan in place. You can associate multiple Azure Web Apps with the same App Service Plan. Hence to save on costs, you can just have one Azure App Service Plan in place. So there is no need for 10 App Service Plans.
