Which approach encrypts data traveling over shared lines so that it is protected from external monitoring?
Container engine
Domain resolution
Dedicated line
Virtual Private Network
A Virtual Private Network (VPN) uses cryptographic methods such as IPsec or TLS to secure traffic over public channels. A dedicated line is a physical link, which is not the same as encrypting data sent over shared infrastructure. A container engine is for running isolated workloads, not encrypting data. Domain resolution associates hostnames with IP addresses, but it does not provide a secure channel.
