AZ-104 Question 263
Single answerYou have two virtual machines (VMs) in the same region. You want to verify connectivity and measure latency between these VMs using Azure Network Watcher with minimal overhead. Which action should you take first?
- A
Enable diagnostic logs on the Network Security Groups attached to both VMs and review the logs
- B
Enable Network Watcher in the region and create a Connection Monitor test
- C
Configure a Traffic Manager profile to direct traffic between the VMs
- D
Create a custom route table with forced tunneling to capture detailed traffic flow
Show answer and explanation
Correct answer: B
Explanation
To use Connection Monitor, you first need to ensure that Network Watcher is enabled in the VM's region. Once it’s enabled, you can create a Connection Monitor test to track the connectivity status, latency, and network metrics between your VMs, fulfilling your monitoring requirements with minimal overhead.
- A. Incorrect.
Enabling diagnostic logs on the NSG does not automatically provide real-time latency measurements or continuous connectivity monitoring between VMs.
- B. Correct.
You must enable Network Watcher in the region before you can create a Connection Monitor test to actively measure connectivity and latency between VMs.
- C. Incorrect.
Traffic Manager is a DNS-based load-balancing solution and is not designed for measuring internal connectivity or latency between two VMs in the same region.
- D. Incorrect.
A custom route table with forced tunneling directs traffic through a specific endpoint, but it does not provide the monitoring or latency metrics you need.
