Your company has deployed several virtual machines (VMs) on-premises and to Azure. Azure ExpressRoute has been deployed and configured for on-premises to Azure connectivity.

Several VMs are exhibiting network connectivity issues.

You need to analyze the network traffic to determine whether packets are being allowed or denied to the VMs.

Solution: Install and configure the Microsoft Monitoring Agent and the Dependency Agent on all VMs. Use the Wire Data solution in Azure Monitor to analyze the network traffic.

Does the solution meet the goal?

A. B.

B

Instead use Azure Network Watcher to run IP flow verify to analyze the network traffic.

Note: Wire Data looks at network data at the application level, not down at the TCP transport layer. The solution doesn't look at individual ACKs and SYNs.

The proposed solution can meet the goal of analyzing network traffic to determine whether packets are being allowed or denied to the VMs.

The Microsoft Monitoring Agent and the Dependency Agent are lightweight agents that can be installed on VMs to collect performance and dependency data, as well as logs and metrics, which can be sent to Azure Monitor for analysis. The agents can be installed on both Windows and Linux VMs running in Azure, on-premises, or other cloud environments.

The Wire Data solution in Azure Monitor is a feature that allows capturing and analyzing network traffic between different endpoints. It uses the Network Performance Monitor (NPM) feature to collect and analyze network traffic data in real-time. With this solution, you can monitor traffic to and from specific VMs, or across the entire virtual network.

By installing and configuring the Microsoft Monitoring Agent and the Dependency Agent on all VMs, and using the Wire Data solution in Azure Monitor, you can analyze network traffic to identify any issues affecting the VMs. This can include identifying whether packets are being allowed or denied, and if there are any network performance issues that are causing connectivity problems.

Therefore, the proposed solution meets the goal of analyzing network traffic to determine whether packets are being allowed or denied to the VMs. The answer is A. Yes.
