What app will Alex use to access the VM remotely that he created on Azure?

To remotely access a virtual machine (VM) created on Azure, Alex will use Remote Desktop Protocol (RDP). RDP is a protocol specifically designed for remote access to Windows-based systems, allowing users to connect to their desktops as if they were sitting directly in front of them. It provides a graphical interface and permits users to interact with the remote machine effectively, including the ability to run applications and manage files as needed.

In the context of Azure, RDP is typically the go-to choice for connecting to Windows VMs. This is because Azure often uses Windows Server for VMs, and RDP is built into Windows for remote management.

Other methods like VNC and SSH serve different purposes: VNC is more suited for cross-platform access to graphical desktops, while SSH (Secure Shell) is commonly used for secure command-line access primarily for Unix/Linux systems. FTP (File Transfer Protocol) is utilized for transferring files, not for remote access to the desktop interface of a VM. This makes RDP the most appropriate option for accessing a Windows VM created in Azure.
