AZ-900 - Microsoft Azure Fundamentals Azure Compute and Networking Questions and Answers

Question 1

A company wants to host a web application in Azure. They require full control over the underlying operating system and want to install custom software. Which Azure compute service is the most appropriate choice?

Accepted Answer

Azure Virtual Machines

Answer

Azure Virtual Machines (VMs) provide Infrastructure-as-a-Service (IaaS), giving users complete control over the operating system and the ability to install any custom software, which meets the company's requirements. Azure App Service is a PaaS offering that abstracts the OS, Azure Functions is for serverless event-driven code, and Container Instances are for running containers without managing servers.

Question 2

What is the primary function of an Azure Virtual Network (VNet)?

Accepted Answer

To enable Azure resources to securely communicate with each other, the internet, and on-premises networks.

Answer

An Azure Virtual Network (VNet) is the fundamental building block for your private network in Azure. It enables many types of Azure resources, such as Azure Virtual Machines (VM), to securely communicate with each other, the internet, and on-premises networks.

Question 3

A development team is building a new web application and wants a Platform-as-a-Service (PaaS) solution that simplifies deployment and management, allowing them to focus on writing code without managing the underlying infrastructure. Which Azure service should they use?

Accepted Answer

Azure App Service

Answer

Azure App Service is a fully managed PaaS offering designed for building, deploying, and scaling web apps and APIs. It handles the infrastructure, OS patching, and maintenance, allowing developers to focus solely on their application code, which directly matches the scenario's requirements.

Question 4

Which of the following Azure networking services provides a dedicated, private connection between an on-premises network and Azure, bypassing the public internet?

Accepted Answer

Azure ExpressRoute

Answer

Azure ExpressRoute lets you extend your on-premises networks into the Microsoft cloud over a private connection facilitated by a connectivity provider. Unlike a VPN Gateway, which sends encrypted traffic over the public internet, ExpressRoute connections do not go over the public internet, offering more reliability, faster speeds, and lower latencies.

Question 5

Your company's e-commerce website experiences high traffic. You need a solution that can make intelligent routing decisions based on the HTTP request's URL path, such as sending traffic for `/images/*` to one pool of servers and `/videos/*` to another. Which Azure service should you use?

Accepted Answer

Azure Application Gateway

Answer

Azure Application Gateway is a web traffic load balancer that operates at the application layer (Layer 7). It can make routing decisions based on attributes of an HTTP request, such as URL path or host headers. This capability allows it to perform URL-based routing, which is exactly what the scenario requires. Azure Load Balancer operates at Layer 4 and cannot inspect HTTP content.
