100-150 Question 235
Select 2A network administrator is tasked with configuring a new router that has no existing configuration. The administrator is working remotely and wants to ensure secure access to the router's command-line interface. Which of the following methods should the administrator use to achieve this?
- A
Use SSH to connect to the router after enabling it through a terminal emulator.
- B
Establish a VPN connection to the network and use SSH to connect to the router.
- C
Connect to the router using telnet for initial configuration.
- D
Access the router's management console using a cloud-managed platform like Meraki.
- E
Write and deploy a configuration script through the router's web-based GUI.
Show answer and explanation
Correct answers: A, B
Explanation
SSH is the preferred method for secure remote access to network devices, but it needs to be enabled first. A terminal emulator can be used for initial setup, or a VPN can provide secure access to the network, allowing SSH to be used. Telnet is insecure and not recommended, and other methods like cloud-managed platforms or GUIs are not relevant to this scenario.
- A. Correct.
SSH is a secure protocol for remote access, but it requires configuration to be enabled. A terminal emulator such as PuTTY can be used to set up SSH access.
- B. Correct.
Establishing a VPN connection ensures secure access to the network, and SSH can then be used for secure communication with the router.
- C. Incorrect.
Telnet is not secure as it transmits data, including credentials, in plaintext. It is not recommended for remote access.
- D. Incorrect.
A cloud-managed platform like Meraki can manage devices, but it is not applicable for direct configuration of a standalone router unless it is part of the Meraki ecosystem.
- E. Incorrect.
Web-based GUIs are not typically used for scripting or initial configuration of routers, and this scenario does not describe a GUI interface being available.
