Question

A company is experiencing network access errors within one department that operates in a secure environment. The network administrator needs to investigate the configurations of the switches servicing that department to determine the cause of the network access errors. Which of the following tools should be used to directly access the switches in that department?

Options

  • AAES
  • BRDP
  • CHTTP
  • DSSH

Why each option

SSH (Secure Shell) is the industry-standard protocol for encrypted, authenticated command-line access to network infrastructure devices like switches and routers. It is the appropriate tool for a network administrator to directly investigate switch configurations in a secure environment.

AAES

AES (Advanced Encryption Standard) is a symmetric encryption algorithm used within other protocols, not a remote access protocol capable of connecting to a switch.

BRDP

RDP (Remote Desktop Protocol) provides GUI-based remote access to Windows desktops and servers, not command-line access to network infrastructure devices like switches.

CHTTP

HTTP is a stateless web transfer protocol and, while some switches expose a web interface over HTTP, it is neither a direct nor a secure access method appropriate for a secure environment.

DSSHCorrect

SSH provides encrypted and authenticated remote CLI access to managed network devices such as switches, making it the correct tool for directly connecting to and troubleshooting infrastructure. It operates on TCP port 22 and is supported by virtually all managed switches, protecting credentials and session data from interception. Unlike insecure alternatives, SSH is specifically designed for administrative access to network devices in security-sensitive environments.
