Why each option

This question tests foundational knowledge of SSH, covering its purpose, scope of use, and core security mechanism. SSH is a cryptographic network protocol designed to replace insecure plaintext remote access protocols.

AIt is the core routing protocol of the Internet.

SSH is a remote access and tunneling protocol, not a routing protocol; the core routing protocols of the Internet are BGP (Border Gateway Protocol) and interior protocols such as OSPF and EIGRP.

BIt was designed as a replacement for TELNET and other insecure shells.Correct

SSH was explicitly created by Tatu Ylonen in 1995 as a secure replacement for TELNET, rlogin, rsh, and other protocols that transmitted credentials and data in plaintext over the network.

CIt is a network protocol used primarily on Linux and Unix based systems.Correct

SSH originated in and remains predominantly used on Linux and Unix-based operating systems for remote administration, though it is now also available on Windows.

DIt allows data to be exchanged using a secure channel between two networked devices.Correct

SSH establishes an encrypted channel between client and server using public-key cryptography and symmetric encryption, ensuring confidentiality and integrity of all exchanged data.
