You need to transfer configuration files to a router across an unsecured network.

TheCCST Cybersecurity Study Guidehighlights thatSSH (Secure Shell)provides encrypted communication for secure remote access and file transfer (using SCP or SFTP) over unsecured networks. This ensures confidentiality and integrity of the files in transit.

"SSH encrypts all data exchanged between client and server, protecting credentials and file contents from interception. It is the preferred protocol for secure device management and file transfers across untrusted networks."

(CCST Cybersecurity,Basic Network Security Concepts, Secure Remote Management section, Cisco Networking Academy)

A(Telnet) transmits data in plaintext.

B(HTTP) is unencrypted web traffic.

C(TFTP) is a simple, insecure file transfer protocol without encryption.

Dis correct: SSH secures configuration file transfers across insecure networks.
