Exam AZ-104 topic 6 question 45 discussion

A is the answer. https://learn.microsoft.com/en-us/azure/network-watcher/network-insights-overview Azure Monitor Network Insights provides a comprehensive and visual representation through topologies, of health and metrics for all deployed network resources, without requiring any configuration. It also provides access to network monitoring capabilities like Connection Monitor, flow logging for network security groups (NSGs), and Traffic Analytics. And it provides other network diagnostic features.

Ans: C expl: Azure Virtual Network Watcher, on the other hand, is a service that provides network topology visualization, diagnostic and visualization tools, and information on virtual network security flow. It allows you to see the topology of your virtual network, and also provides detailed metrics and visual representation of the network topology which is the requirement mentioned in the question.

A is correct

A is correct

Keyword 'visual representation', choose Azure Monitor Network Insights.

A There are two topology features offered in Azure. One is Azure Monitor network insights and the other is Network Watcher Topology. They both have a specific set of resources they can be used on with some overlap but only Azure Monitor network insights works on Express routes. The resources they work on are listed in each page towards the bottom. https://learn.microsoft.com/en-us/azure/network-watcher/network-insights-overview https://learn.microsoft.com/en-us/azure/network-watcher/view-network-topology?tabs=portal

Based on https://learn.microsoft.com/en-us/azure/expressroute/monitor-expressroute, Network Watcher is not even stated as a tool to view topology for ExpressRoute.

"Some services in Azure have a special focused pre-built monitoring dashboard in the Azure portal that provides a starting point for monitoring your service. These special dashboards are called "insights". ExpressRoute uses Network insights to provide a detailed topology mapping of all ExpressRoute components (peerings, connections, gateways) in relation with one another. Network insights for ExpressRoute also have preloaded metrics dashboard for availability, throughput, packet drops, and gateway metrics. For more information, see Azure ExpressRoute Insights using Networking Insights." --->https://learn.microsoft.com/en-us/azure/expressroute/monitor-expressroute

Isn't Azure Virtual Network Watcher actually called (Azure) Network Watcher (ie no virtual). I know its splitting hairs but I would therefore go for A

Network typology = network watcher

If you need a "visual representation of the network topology" as in the question, you have to use Network Watcher. https://learn.microsoft.com/EN-US/azure/network-watcher/view-network-topology?tabs=portal

A is the answer. Network Insights can help you view your ExpressRoute metrics and configurations all in one place. Through Network Insights, you can view topological maps and health dashboards containing important ExpressRoute information without needing to complete any extra setup. https://learn.microsoft.com/en-us/azure/expressroute/expressroute-network-insights

Selected Answer A: ExpressRoute uses Network insights to provide a detailed topology mapping of all ExpressRoute components (peerings, connections, gateways) in relation with one another. Network insights for ExpressRoute also have preloaded metrics dashboard for availability, throughput, packet drops, and gateway metrics. Ref: https://learn.microsoft.com/en-us/azure/expressroute/monitor-expressroute#expressroute-insights

To create a dashboard with detailed metrics and a visual representation of the network topology for your Azure virtual network (VNet1), you should use Azure Virtual Network Watcher (option C).

It seems to me that Azure Network Watcher topology visualization is still in preview and can handle only limited resources (Azure Express Route is not included). So I would definitely go with answer A - Azure Monitor Network Insights

ChatGPT C. Azure Virtual Network Watcher Explanation: To create a dashboard to display detailed metrics and a visual representation of the network topology in Azure, you can use Azure Virtual Network Watcher. Azure Virtual Network Watcher provides a set of networking monitoring and diagnostic tools that help you to monitor, diagnose, and gain insights into the network performance and health of your Azure virtual network. Azure Monitor Network Insights is a service that helps you to monitor and diagnose network performance and connectivity issues in your Azure network environment. However, it does not provide the capability to create a dashboard for displaying network topology.
