Microsoft Azure Architect Design (AZ-304) Practice Test

What should be recommended to collect MAC addresses from all devices in an Azure-managed environment?

1. Activity Log Analytics

2. Azure Network Security Group Analytics

3. Network Performance Monitor

4. Azure Wire Data

The correct answer is: Azure Network Security Group Analytics

The recommendation to use Azure Network Security Group Analytics for collecting MAC addresses from all devices in an Azure-managed environment is particularly sensible because Network Security Groups (NSGs) are vital in managing network traffic to and from Azure resources. They contain rules that control the inbound and outbound traffic at the network interface or subnet level. Using Azure Network Security Group Analytics allows for monitoring network traffic data, including information about network flows and the devices involved in those flows. Although traditionally, MAC addresses are more relevant in local network contexts, NSGs can still provide telemetry that aggregates data about various network interfaces, including any reported MAC addresses as part of the network flow analysis. Other options may provide valuable insights into network performance and security, but they do not focus as directly on the specific task of collecting MAC addresses across devices in an Azure-managed environment. For instance, Activity Log Analytics is primarily geared towards tracking activity logs and auditing purposes, which do not center around MAC address collection. Network Performance Monitor focuses more on performance metrics rather than device-specific details like MAC addresses. Azure Wire Data is designed for analyzing network traffic but involves more complex telemetry and might not provide the focused view on MAC addresses that NSGs can provide. Thus, for the specific need to collect MAC addresses, leveraging Azure
