Protecting Azure Stack Hub VMs Running Linux OS

Correct Answer: E

For protecting Azure Stack Hub VMs that run Linux OS, you need to: Build a root user account.

This account can be specified while enabling Azure Site Recovery upon these VMs.

This account is used by the process server for installing the Azure Site Recovery Mobility service.

Installing the latest OpenSSH, OpenSSL packages, and OpenSSH-server.

Enabling and Running SSH port 22.

Enabling Secure FTP subsystem and password authentication.

Option A is incorrect.

Creating a root user account is a mandatory step to protect the Azure Stack Hub VMs.

But it is not the only one.

All the given options are true.

Option B is incorrect.

All the given options including B are the mandatory steps to protect the Azure Stack Hub VMs that run Linux OS.

Option C is incorrect.

Enabling and running Secure Shell (SSH) port 22 is a mandatory but not only step to protect the Azure Stack Hub VMs.

All the given options are true.

Option D is incorrect.

Enabling the Secure FTP subsystem and password authentication is a mandatory thing to perform for protecting the Azure Stack Hub VMs that run Linux OS.

But the other given options also represent the necessary steps.

Option E is correct.

All the given options are correct.

To protect Azure Stack Hub VMs that run Linux OS, you need to perform the following steps:

A. Creating a root user account: This step is important because it enables you to have full control over the VM and make changes to the system as required. By creating a root user account, you can log in as the root user and perform any required system-level tasks.

B. Installing the latest OpenSSH, OpenSSH-server, and OpenSSL packages: These packages are required to enable secure communication with the VM. OpenSSH is used to connect to the VM remotely over a secure connection, and OpenSSL is used to encrypt the communication between the client and the server. Installing the latest versions of these packages ensures that any security vulnerabilities are patched and that the communication between the client and the server is secure.

C. Enabling and running Secure Shell (SSH) port 22: SSH is a secure protocol that is used to connect to the VM remotely. By default, the SSH port 22 is disabled on Linux VMs. You need to enable it to be able to connect to the VM remotely. To enable the SSH port, you need to modify the firewall rules and allow traffic on port 22.

D. Enabling Secure FTP subsystem and password authentication: This step is not necessary to protect Azure Stack Hub VMs that run Linux OS. In fact, Secure FTP is an outdated protocol and is not recommended for use. Instead, you should use SFTP (Secure File Transfer Protocol), which is a secure alternative to FTP. Additionally, password authentication is not recommended as it can be easily compromised. It is recommended to use key-based authentication instead.

Therefore, the correct answer is E. All of the above except for D.
