Exam N10-008 topic 1 question 182 discussion

B, its the only option that lets you update multiple switches at once, every other option is one-by-one

TFTP Server: Setting up a TFTP (Trivial File Transfer Protocol) server allows you to store the security update files in one location. This avoids the need to transfer files individually to each switch. SSH: Secure Shell (SSH) is a secure protocol used for remote access and management of network devices. SSH provides encryption and secure authentication, making it the preferred method for accessing devices remotely. By combining TFTP and SSH, the technician can: Transfer Update Files: Upload the security update files to the TFTP server. SSH into Devices: Securely access each switch using SSH, which ensures a secure connection. Retrieve Updates: From the switch's command-line interface (CLI), retrieve the update files from the TFTP server. Perform Updates: Apply the security updates on each switch. This approach minimizes the need for physical access, speeds up the update process, and ensures that updates are performed securely and efficiently. It also allows centralized control over the update process and reduces potential downtime.

The keyword here is physical access. They want to check which option does not use physical access. Another very bad question with no sense

The most efficient and effective way to perform security updates on several switches in a network is to configure a TFTP server, SSH into each device, and perform the update (Option B). This method allows the technician to update multiple switches simultaneously, without having to physically access each switch. Options A, C, and D would either be time-consuming, expensive, or still require physical access to each switch.

Configure a TFTP server, SSH into each device, and perform the update.
