Show answer & explanation
Correct answer: C
Technologies like:
IPsec
IP encapsulation
Tunneling protocol
are core building blocks of a Virtual Private Network (VPN).
Why these are used in VPN
A VPN creates a secure “tunnel” over a public network (like the Internet):
IPsec → provides encryption, authentication, integrity
Encapsulation → wraps original packets inside new packets
Tunneling → sends data securely through an “invisible path”
Together, they allow private communication over public infrastructure.
