D.

A network technician needs to set up an access method for Ann, a manager, to work from home.

Ann needs to locally mapped corporate resources to perform her job.

Which of the following would provide secure access to the corporate resources?

A.

Utilize an SSH connection to the corporate server.

B.

Use TFTP to transfer files to corporate resources.

C.

Allow RDP through an external firewall.

D.

Connect utilizing client-to-site VPN.

D.

The correct answer for this question is D. Connect utilizing client-to-site VPN.

A VPN (Virtual Private Network) is a secure method to connect remote workers to the corporate network. It creates a secure, encrypted tunnel between the remote worker's computer and the corporate network, ensuring that all the data transmitted between them is encrypted and secure.

Client-to-site VPN is a type of VPN that enables remote workers to connect securely to the corporate network by using VPN client software installed on their computer. Once the connection is established, the remote worker can access corporate resources as if they were on the same network.

Option A, utilizing an SSH connection to the corporate server, is not the best choice for providing remote access to corporate resources. SSH is a secure protocol for remote access to servers, but it is typically used for command-line access and does not provide access to mapped network drives or printers.

Option B, using TFTP to transfer files to corporate resources, is not a secure method of remote access as TFTP does not provide encryption.

Option C, allowing RDP through an external firewall, is also not a secure method of remote access as RDP (Remote Desktop Protocol) does not provide encryption and is vulnerable to attacks such as brute-force password attacks.

Therefore, the most secure method of remote access to corporate resources for Ann is to use client-to-site VPN.
