Which of the following statements are true about the Python code shown below? (Select all that apply)
import paramiko
import time
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(‘192.168.1.254′, username=’python’, password=’Huawei@123′)
channel = ssh.invoke_shell()
channel.send(‘screen-length 0 temporaryn’)
time.sleep(1)
output = channel.recv(65535). decode(‘utf-8’)
print(output)
ssh.close()
