Azure Fundamentals (AZ-900) Questions and Answers Graded A+

Azure Fundamentals (AZ-900) Questions and Answers Graded A+ Azure Microsoft's cloud computing platform Cloud Computing The delivery of computing services over the Internet using a pay-as-you- go pricing model. Infrastructure as a Service Instead of maintaining CPU's, Memory and Storage in your data center, you rent them for the time that you need them. The cloud provider takes care of maintaining the underlying infrastructure for you. Platform as a Service A complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications. Software as a Service A complete software solution that you purchase on a pay-as-you-go basis from a cloud service provider. You rent the use of an app for your organization, and your users connect to it over the Internet, usually with a web browser. Azure Virtual Machines Windows or Linux virtual machines (VMs) hosted in Azure. Azure Virtual Machine Scale Sets A tool to help you create and manage a group of identical, load balanced VMs. Azure Kubernetes Service A complete orchestration service for containers with distributed architectures with multiple containers. Azure Service Fabric Distributed systems platform. Runs in Azure or on-premises. Azure Batch Managed service for parallel and high-performance computing applications. Azure Container Instances Offers the fastest and simplest way to run a container in Azure. You don't have to manage any virtual machines or configure any additional services. It is a PaaS offering that allows you to upload your containers and execute them directly with automatic elastic scale. Azure Functions An event-driven, serverless compute service for when you're concerned only about the code running your service, and not the underlying platform or infrastructure. They're commonly used when you need to perform work in response to an event, often via a REST request, timer, or message from another Azure service and when that work can be completed quickly, within seconds or less. Azure Virtual Network The fundamental building block for your private network in Azure. It will enable many types of Azure resources, such as Azure Virtual Machines (VM), to securely communicate with each other, the internet, and on-premises networks. While similar to a traditional network that you'd operate in your own data center, it will also bring with it additional benefits of Azure's infrastructure such as scale, availability, and isolation. Azure VPN Gateway A specific type of virtual network gateway that is used to send encrypted traffic between an Azure virtual network and an on-premises location over the public Internet. You can also use a VPN gateway to send encrypted traffic between Azure virtual networks over the Microsoft network. Each virtual network can have only one VPN gateway Azure DNS Provides ultra-fast DNS responses and ultra-high domain availability. Azure Content Delivery Network A distributed network of servers that can efficiently deliver web content to users. It is a way to get content to users in their local region to minimize latency. It can be hosted in Azure or any other location. You can cache content at strategically placed physical nodes across the world and provide better performance to end users. Azure DDoS Protection Protects Azure-hosted applications from distributed denial of service (DDOS) attacks. Azure Traffic Manager A service that uses the DNS server that's closest to the user to direct their client browser to the nearest endpoint, it can also direct a user to the endpoint with the lowest latency. Azure ExpressRoute Connects to Azure over high-bandwidth
