Answers
C.
Virtual private network (VPN)
D.
Virtual desktop
Answers
D.
Virtual desktop
Suggested answer: C

Explanation:

The best solution for ensuring secure remote access to corporate resources is to use a virtual private network (VPN), as this creates an encrypted tunnel between the user's device and the corporate network, preventing unauthorized interception or modification of data in transit. Additional firewall rules may help to restrict access to certain ports or protocols, but they do not provide encryption or authentication. Multi-factor authentication may help to verify the identity of the user, but it does not protect the data in transit.Virtual desktop may help to provide a consistent user interface and access to applications, but it does not ensure the security of the communication channel.Reference:CISA Review Manual (Digital Version), Chapter 5: Protection of Information Assets, Section 5.2: Network Security Devices and Technologies
