  1. SSH (Secure Shell)Cevap
  2. Port 22Cevap
  3. C
    Telnet
  4. D
    Port 23

Cevap

SSH (Secure Shell) and TCP Port 22 must be selected to secure in-band remote management.
SSH (Secure Shell) and TCP port 22 are the standard protocol and port combination used for encrypted in-band command-line access to network infrastructure switches and routers.

Adım Adım Çözüm

1
Identify the security requirement for remote management
The requirement specifies that administrative sessions must be encrypted.
Encryption prevents eavesdropping and credential theft across the network.
2
Select the appropriate protocol and default port number
SSH provides encrypted CLI management and operates by default on TCP port 22.
Telnet and port 23 transmit traffic in plaintext and do not meet the security requirement.
