Question 20

SSH allows the company to securely and remotely access network devices.

SSH (Secure Shell) is a protocol that provides a secure channel over an unsecured network in a client-server architecture, enabling secure remote access to network devices.

A) Telnet

Telnet is an older protocol that allows for remote communication but does not encrypt data, making it vulnerable to eavesdropping and attacks. Therefore, it does not meet the security requirements necessary for safe remote access to network devices.

B) TKIP

TKIP (Temporal Key Integrity Protocol) is a security protocol designed to provide encryption for wireless networks, specifically as part of the WPA (Wi-Fi Protected Access) standard. However, it is not designed for remote access to network devices and thus does not fulfill the requirements of the question.

C) RDP

RDP (Remote Desktop Protocol) is primarily used for remotely accessing Windows desktops and servers. While it provides remote access, it is not specifically designed for accessing network devices and may not be as secure as SSH for this purpose.

D) SSH

SSH is the ideal choice for securely accessing network devices remotely. It provides strong authentication and encryption, ensuring that data transmitted over the network is protected from interception.

Conclusion

SSH is definitively the correct option for securely and remotely accessing network devices due to its robust security features, including encryption and authentication. In contrast, Telnet, TKIP, and RDP either lack the necessary security measures or are not designed for accessing network devices, making them unsuitable options for the company's needs.
