Rahul, an employee of a Pune firm, works from home and connects to the office server through a VPN. What is the principal security benefit the VPN provides for this connection?

A VPN's principal benefit is that it creates an encrypted tunnel across the public internet, so data travelling between Rahul's home and the office is protected from interception. It does not replace authentication, remove malware risk on the device, or act as a firewall.

  3. CIt creates an encrypted tunnel over the public internet so data in transit is protected from interceptionCorrect
  4. DIt permanently blocks all unsolicited incoming connections to the office network

Explanation

A VPN encapsulates and encrypts traffic across the public network, protecting confidentiality and integrity in transit. It does not replace authentication, does not clean an infected endpoint, and is not a firewall for blocking inbound connections.
