Question

Your on-premises network is connected to Azure. You have an Azure subscription. The subscription contains a virtual machine named VM1 that runs Windows Server. You need to identify the latency between the on-premises network and VM1. Which Azure Network Watcher settings should you use?

Options

AIP flow verify
BConnection monitor
CVPN troubleshoot
DConnection troubleshoot

Explanation

To identify latency between an on-premises network and an Azure virtual machine, Azure Network Watcher's Connection Monitor should be used as it provides continuous, end-to-end monitoring of connectivity, latency, and packet loss.

Common mistakes.

A. IP flow verify is used to check if network security group (NSG) rules allow or deny traffic, not to measure network latency.
C. VPN troubleshoot is used for diagnosing issues with VPN gateways and connections, not for general latency measurement between an on-premises host and an Azure VM.
D. Connection troubleshoot performs a one-time check for connectivity and can provide latency data for that moment, but Connection Monitor offers continuous, historical monitoring which is more suitable for identifying latency over time.
