Free Isaca Cybersecurity Audit Certificate Actual Exam Questions - Question 15 Discussion

This one definitely feels like C. VPN and IPsec are more about securing connections or networks, not about opening command-line shells directly. SFTP is for file transfers, so it doesn't fit the "command-line shell session" part. SSH is the standard tool used to remotely log in securely via a shell, so it matches best here.

Maybe C, since VPN and IPsec handle network layers, not direct shell access.

Makes sense that it’s C since SSH is designed to open secure shell sessions remotely. VPN and IPsec handle broader network security, and SFTP is just for transferring files, so they don’t fit here.

C imo, since VPN and IPsec are protocols for secure communication at the network level, not for accessing a remote shell directly. SFTP is just a secure file transfer protocol, no shell access involved. SSH specifically provides that encrypted command-line interface, so it fits the question perfectly.

It’s C because SSH allows you to remotely access a shell securely, unlike VPN or IPsec which focus on network security layers, and SFTP just handles file transfers, not command-line sessions.

I agree that VPN and IPsec are more about securing networks rather than providing a direct command-line interface. Also, SFTP is mainly for file transfers, not interactive shell sessions. So, the question really narrows down to the option that specifically handles secure remote logins. Could it be that the focus is on the “encrypted command-line shell session,” which points directly to something designed for secure shell access? Does anyone see a reason why SSH wouldn’t be the best fit here?

Option C makes the most sense because VPN and IPsec are more about creating secure networks, not just a command-line shell. SFTP is for file transfer, so it can’t be the answer here.

It’s C for sure. SSH is exactly that secure remote login thing, right? Not sure why they added SFTP in there, feels confusing.
