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: Use Azure Network Watcher to run IP flow verify to analyze the network traffic.

A. B.A
The Network Watcher Network performance monitor is a cloud-based hybrid network monitoring solution that helps you monitor network performance between various points in your network infrastructure. It also helps you monitor network connectivity to service and application endpoints and monitor the performance of
Azure ExpressRoute.
Note:
IP flow verify checks if a packet is allowed or denied to or from a virtual machine. The information consists of direction, protocol, local IP, remote IP, local port, and remote port. If the packet is denied by a security group, the name of the rule that denied the packet is returned. While any source or destination IP can be chosen,
IP flow verify helps administrators quickly diagnose connectivity issues from or to the internet and from or to the on-premises environment.
IP flow verify looks at the rules for all Network Security Groups (NSGs) applied to the network interface, such as a subnet or virtual machine NIC. Traffic flow is then verified based on the configured settings to or from that network interface. IP flow verify is useful in confirming if a rule in a Network Security Group is blocking ingress or egress traffic to or from a virtual machine.

The scenario describes that several VMs are experiencing network connectivity issues, and the objective is to determine whether packets are being allowed or denied to the VMs.
Azure Network Watcher is a cloud-based network monitoring and diagnostic service that provides tools to monitor, diagnose, and gain insights into network performance and health in Azure. One of the features offered by Network Watcher is IP flow verify, which allows administrators to verify if traffic is allowed or denied to a VM.
By running IP flow verify on the VMs, Network Watcher will analyze the network traffic and provide information on whether packets are being allowed or denied. This analysis will help administrators identify the source of the connectivity issue and take appropriate measures to resolve it.
Therefore, using Azure Network Watcher to run IP flow verify is an appropriate solution to analyze the network traffic and determine whether packets are being allowed or denied to the VMs.
