Your Azure environment contains multiple Azure virtual machines.
You need to ensure that a virtual machine named VM1 is accessible from the Internet over HTTP.
Solution: You modify an Azure Traffic Manager profile.
Does this meet the goal?
A. Yes
B. No
Answer
B. No, modifying an Azure Traffic Manager profile does not meet the goal of making the virtual machine VM1 accessible from the Internet over HTTP.
Explanation
Azure Traffic Manager is a DNS-based load balancing solution. It is not used to ensure that a virtual machine named VM1 is accessible from the Internet over HTTP.
To ensure that a virtual machine named VM1 is accessible from the Internet over HTTP, you need to modify a network security group or Azure Firewall.
In this question, we need to add a rule to a network security group or Azure Firewall to allow the connection to the virtual machine on port 80 (HTTP).
Azure Traffic Manager is a DNS-based traffic load balancer that enables you to distribute traffic optimally to services across global Azure regions. While Traffic Manager can direct traffic to different endpoints, including Azure virtual machines, it does not directly expose virtual machines to the Internet or enable HTTP access.
To make VM1 accessible from the Internet over HTTP, you would need to take the following steps:
- Assign a public IP address to the virtual machine or use a load balancer with a public IP address.
- Configure Network Security Group (NSG) rules to allow inbound HTTP traffic (port 80) to the virtual machine.
- Ensure the virtual machine is running a web server and properly configured to respond to HTTP requests.
Traffic Manager can be used in conjunction with these steps to distribute traffic to VM1 and other virtual machines for load balancing and high availability. However, modifying a Traffic Manager profile alone does not expose VM1 directly to the Internet over HTTP.
The solution of modifying an Azure Traffic Manager profile does not directly meet the goal of making VM1 accessible from the Internet over HTTP. Additional steps like assigning a public IP, configuring NSG rules, and running a web server are necessary.
