Answer
Brief Explanations:
An open network is insecure for accessing company - internal files. MFA (Multi - Factor Authentication) is a security method but not a means to access the internal network. Using just a cellphone without proper network setup won't work. A VPN (Virtual Private Network) creates a secure connection to the company's internal network, allowing access to shared files while traveling.
Answer:
C. VPN
