You have VMs in two peered virtual networks (VM1 in VNet1 and VM2 in VNet2). To view the average round-trip time (RTT) for packets from VM1 to VM2, which Azure Network Watcher feature should you use?

Connection monitor is the correct choice because it continuously monitors connectivity between a source (VM1) and a destination (VM2), providing metrics like average RTT, packet loss, and network topology changes over time. This ongoing monitoring is essential for understanding performance trends and diagnosing intermittent issues. IP flow verify checks if a packet is allowed or denied to/from a VM based on NSG rules, but it doesn't measure RTT. Connection troubleshoot performs a one-time connectivity check and provides a snapshot of the path and NSG rules, but it doesn't offer continuous RTT monitoring. NSG flow logs record information about IP traffic through an NSG, which is useful for security auditing and traffic analysis, but not for measuring RTT.
