Which of the following is a best practice for securing virtual environments?

Question

Options

• AAllowing unrestricted access to virtual machines from the internet
• BNone of the above
• CRegularly applying security updates to virtual machines
• DUsing the same administrative password across all virtual machines

• A
  6% (3)
• B
  2% (1)
• C
  90% (43)
• D
  2% (1)

Explanation

Virtual machines (VMs) run operating systems and applications that are just as vulnerable to exploits as physical systems. Regularly patching and updating them closes known security vulnerabilities. Option A is dangerous because unrestricted internet access exposes VMs to external threats. Option D violates the principle of least privilege and password uniqueness - sharing passwords across all VMs means a single compromise can cascade to all machines. Therefore, C is the only security best practice listed.
