Microsoft Azure Architect Design (AZ-304) Practice Test

What solution should be implemented to analyze network traffic for virtual machines in Azure if connectivity issues are reported?

1. Install a virtual network gateway

2. Deploy network security groups (NSGs)

3. Utilize the Microsoft Monitoring Agent and Dependency Agent

4. Set up ExpressRoute

The correct answer is: Utilize the Microsoft Monitoring Agent and Dependency Agent

The use of the Microsoft Monitoring Agent and Dependency Agent is appropriate when analyzing network traffic and diagnosing connectivity issues for virtual machines in Azure. These agents can provide insights into the performance and health of applications, as well as the underlying network connections. By collecting telemetry and metrics, the agents can help identify any anomalies or disruptions in the network traffic, allowing for tailored troubleshooting efforts. The Microsoft Monitoring Agent specifically gathers performance data from the VMs while the Dependency Agent collects data related to the dependencies of applications running on those VMs. Together, they enhance visibility into the communication patterns between different components and services, which is essential for diagnosing connectivity problems. While other options like a virtual network gateway are important for establishing secure connections and routing traffic, they do not provide analysis capabilities specifically targeted at diagnosing connectivity issues. Network security groups can manage inbound and outbound traffic but won't directly provide the analysis needed for troubleshooting. Setting up ExpressRoute is a network connection option that facilitates an on-premises network connection to Azure but does not address the need for monitoring and analyzing traffic for issues.
