Demo Questions
Question 1
You need to troubleshoot the CosmosDB1 issues from the on-premises environment. What should you use?
- route command
- Network Watcher next hop diagnostic tool
- Network Watcher Connection troubleshoot diagnostic tool
- nslookup command
Correct answer: C
Explanation:
This tool helps you troubleshoot network connectivity issues from a virtual machine to a given endpoint. It tests for reachability from the virtual machine to the endpoint and provides information about why a connection fails1. In this case, you can use this tool to troubleshoot the connectivity issues from the on-premises environment to CosmosDB1.

Question 2
You need to resolve the issue with internet traffic from VM1 being routed directly to the internet.
What should you do?
- Modify IP address prefix of RT12
- Associate RT12 with Subnet1a.
- Associate RT12 with Subnet2a.
- Modify the next hop type of RT12.
Correct answer: B
Explanation:
This will ensure that the route table RT12, which has a route to direct internet traffic to the virtual network gateway VNG1, is applied to the subnet where VM1 is located. This will override the default route that sends internet traffic to the internet gateway. This will ensure that the route table RT12, which has a route to direct internet traffic to the virtual network gateway VNG1, is applied to the subnet where VM1 is located. This will override the default route that sends internet traffic to the internet gateway.
Question 3
You need to resolve the VM2 routing issue.
What should you do?
- Modify the IP configuration setting of the Azure network interface resource of VM1.
- Add a network interface to VM1.
- Add a network interface to VM2.
- Modify the IP configuration setting of the Azure network interface resource of VM2.
Correct answer: D
Explanation:
To resolve the VM2 routing issue, you should modify the IP configuration setting of the Azure network interface resource of VM2. This will ensure that VM2 can communicate with other resources in the virtual network. Troubleshooting connectivity problems between Azure VMs involves several steps such as checking whether NIC is misconfigured, whether network traffic is blocked by NSG or UDR, whether network traffic is blocked by VM firewall, whether VM app or service is listening on the port and whether the problem is caused by SNAT1.
