Microsoft Azure Administrator (AZ104) Practice Exam

You need to assess the average round-trip time (RTT) of packets between two Azure virtual machines. What feature of Azure Network Watcher should you use?

1. IP flow verify

2. Connection troubleshoot

3. Connection monitor

4. NSG flow logs

The correct answer is: Connection monitor

The average round-trip time (RTT) of packets between two Azure virtual machines can be effectively assessed using the Connection Monitor feature within Azure Network Watcher. Connection Monitor is designed to monitor the connectivity between virtual machines and other resources in Azure and can provide insights into network performance and latency metrics, including RTT. This feature allows you to create a monitoring configuration that periodically sends packets from one VM to another and measures the time it takes for those packets to round-trip. By displaying historical performance metrics, Connection Monitor enables you to analyze trends and identify potential network issues, helping ensure optimal performance. Other features, while useful in their own right, do not specifically measure RTT. IP flow verify helps determine whether packets are allowed or denied through the Network Security Group (NSG), whereas connection troubleshoot can assist with diagnosing connectivity issues but does not specifically measure latency or RTT. NSG flow logs capture detailed information about the traffic going to and from the network interface, but they do not provide real-time insight into round-trip times or network performance metrics.
