AZ-104 Question 262
Single answerA multi-tier application is deployed across two Azure VMs: one in the West Europe region and another in the East US region. You need to monitor end-to-end network connectivity and measure latency between these two VMs. Which action should you take using Azure Network Watcher and Connection Monitor?
- A
Create a Network Watcher instance in each region and configure Connection Monitor to test connectivity between the West Europe and East US VMs
- B
Enable Just-in-Time (JIT) VM access to troubleshoot connectivity issues between the regions
- C
Configure service endpoints for all subnets involved to measure performance between both VMs
- D
Use Azure Traffic Manager to dynamically route traffic to monitor latency across regions
Show answer and explanation
Correct answer: A
Explanation
Connection Monitor in Azure Network Watcher is specifically designed to monitor and troubleshoot end-to-end connections between Azure resources. Creating Network Watcher instances in each region and configuring tests for your VMs allows you to continuously observe latency, packet loss, and other connectivity metrics, fulfilling your requirement to ensure seamless communication between the multi-tier application components.
- A. Correct.
By setting up Network Watcher in both regions and configuring Connection Monitor, you can continuously test and measure the connection (including latency) between the two VMs.
- B. Incorrect.
Just-in-Time VM access helps reduce exposure to network attacks by limiting management ports and does not directly provide detailed connectivity monitoring.
- C. Incorrect.
Service endpoints secure connections to specific Azure services by extending your virtual network identity, but they do not offer continuous end-to-end connectivity monitoring.
- D. Incorrect.
Traffic Manager optimizes DNS routing for internet-based clients and can help with global routing decisions, but it does not provide detailed connection or latency metrics between your Azure VMs.
