Exam SY0-601 topic 1 question 78 discussion

Telnet (port 23) is insecure and should be replaced with SSH (port 22)

Answer: SSH (22) Port 23 (Telnet) and Port 22 (SSH) are network protocols used to remotely access and manage systems however telnet does not encrypt the connection so captured traffic appears in cleartext whereas an ssh connection would be encrypted. ========================= SNMP (Simple Network Management Protocol) - is a protocol for collecting and organizing information about managed devices on networks. Devices that typically support SNMP include servers/desktops, routers, switches, etc. SFTP (Secure File Transfer Protocol) is a secure file transfer protocol that uses SSH encryption to securely sending and receiving file transfers. FTP (File Transfer Protocol) - For file transfers

SNMPv3 offers security features such as authentication and encryption, which ensure that credentials and other sensitive data exchanged between SNMP managers and agents are protected from unauthorized access and interception.

A. SSH

SSH (Secure Shell) is a cryptographic network protocol used to securely access and manage network devices remotely. Unlike Telnet (Option D), which sends credentials in cleartext over port 23, SSH encrypts all communication between the client and server, providing a secure remote login and management solution. It ensures that administrative usernames and passwords are not sent in plaintext, making it the best choice for securing remote access to network devices.

SSH is a cryptographic network protocol designed for secure remote login, command execution, and data communication. It provides strong encryption and authentication mechanisms, protecting the confidentiality and integrity of the transmitted data, including usernames and passwords. Unlike Telnet (option D), which sends data in clear text, SSH encrypts the communication channel, preventing unauthorized interception and eavesdropping.

A is correct

ssh replaces telnet in that it provides an encrypted session. Telnet sends in clear text, unsecure.

A. SSH. SSH is an encryption protocol used to connect to systems.
