AZ-900 Networking and Connectivity in Azure Flashcards
Microsoft Azure Fundamentals AZ-900 Flashcards

| Front | Back |
| How does Azure ensure secure hybrid connectivity | Azure ensures secure hybrid connectivity using solutions like VPN Gateways, ExpressRoute, and Azure Virtual WAN. |
| How does Azure Load Balancer distribute network traffic | Azure Load Balancer distributes incoming traffic across multiple virtual machines or resources to ensure availability and scalability. |
| How does Traffic Manager handle endpoint outages | Traffic Manager automatically reroutes traffic to available endpoints when an endpoint becomes unavailable to maintain service continuity. |
| What feature allows Azure VNets to connect directly with each other | VNet Peering enables direct connectivity between Azure VNets, allowing them to communicate as if they were part of the same network. |
| What is a Service Endpoint in Azure networking | A Service Endpoint allows Azure resources in a VNet to connect securely to Azure services over the Azure backbone network. |
| What is a Virtual Network (VNet) in Azure | A Virtual Network (VNet) is a logically isolated network in Azure that allows Azure resources to securely communicate with each other and on-premises networks. |
| What is Azure Bastion | Azure Bastion provides secure RDP and SSH access to virtual machines directly through the Azure portal without exposing VMs to the public internet. |
| What is Azure ExpressRoute | Azure ExpressRoute is a dedicated, private connection between an on-premises network and Azure, bypassing the public internet for enhanced security and reliability. |
| What is the difference between public and private load balancers in Azure | Public Load Balancers route external traffic to resources, while Private Load Balancers manage traffic within a virtual network. |
| What is the primary advantage of using Azure ExpressRoute over VPN Gateway | ExpressRoute offers higher reliability, faster speeds, and lower latencies since it avoids the public internet. |
| What is the primary function of Azure DNS | Azure DNS manages and resolves domain names in Azure, enabling resources to use user-friendly DNS names. |
| What is the purpose of a Network Security Group (NSG) in Azure | An NSG is used to filter network traffic to and from Azure resources in a virtual network, providing security at the network layer. |
| What is the purpose of an Azure Traffic Manager | Azure Traffic Manager uses DNS-based routing to direct user traffic to the most appropriate endpoint, improving performance and availability. |
| What is the role of a VPN Gateway in Azure | A VPN Gateway is used to establish secure connections between on-premises networks and Azure virtual networks through site-to-site or point-to-site VPNs. |
| What is the role of Application Gateway in Azure networking | Application Gateway is a Layer 7 load balancer providing application delivery features, including SSL offloading, URL routing, and WAF functionality. |
About the Flashcards
Flashcards for the Microsoft Azure Fundamentals exam give you a quick way to solidify Azure networking fundamentals. Review how Virtual Networks isolate resources, how Network Security Groups filter traffic, and how Load Balancers-public, private, or application-layer-keep workloads highly available and scalable.
The deck also clarifies hybrid and cross-network options such as VPN Gateways, ExpressRoute links, VNet Peering, and Service Endpoints, along with name resolution through Azure DNS and global routing with Traffic Manager. Each card focuses on exam-level terminology and real-world use cases so you can recognise the right service, compare features, and select secure designs on test day.
Topics covered in this flashcard deck:
- Azure Virtual Networks
- Network Security Groups
- Load Balancing options
- Hybrid connectivity tools
