Which of the following uses TCP port 22 by default? (Choose three.)

A.
FTPS

B.
STELNET

C.
TLS

D.
SCP

E.
SSL

F.
HTTPS

G.
SSH

H.
SFTP

Explanation:
G: Secure Shell (SSH) is a cryptographic network protocol for securing data communication. It establishes a
secure channel over an insecure network in a client-server architecture, connecting an SSH client application
with an SSH server. Common applications include remote command-line login, remote command execution,
but any network service can be secured with SSH. SSH uses port 22.
D: SCP stands for Secure Copy. SCP is used to securely copy files over a network. SCP uses SSH to secure
the connection and therefore uses port 22.
H: SFTP stands for Secure File Transfer Protocol and is used for transferring files using FTP over a secure
network connection. SFTP uses SSH to secure the connection and therefore uses port 22.
