AZ-900 Networking and Connectivity in Azure 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. |
