Explanation
A keyboard-video-mouse (KVM) system is commonly used for directly accessing server terminals in a data center. It is not a method that would be possible within a cloud environment, primarily due to the use virtualized systems, but also because only the cloud provider's staff would be allowed the physical access to hardware systems that's provided by a KVM. Hypertext Transfer Protocol Secure (HTTPS), virtual private network (VPN), and Transport Layer Security (TLS) are all technologies and protocols that are widely used with cloud implementations for secure access to systems and services.

DNSSEC is used as a security extension to DNS lookup queries in order to ensure the authenticity and authoritativeness of hostname resolutions, in order to prevent spoofing and redirection of traffic. Although it is a very important concept to be employed for security practices, it is not used to secure or encrypt data transmissions. HTTPS is the most commonly used security mechanism for data communications between clients and websites and web services.
IPSec is less commonly used, but is also intended to secure communications between servers.
VPN is commonly used to secure traffic into a network area or subnet for developers and administrative users.

The create phase encompasses any time data is created, imported, or modified. With any change in the content or value of data, the classification may also change. It must be continually reevaluated to ensure proper security. During the use, share, and archive phases, the data is not modified in any way, so the original classification is still relevant.

Explanation:
A retina scan could be used in conjunction with an RSA token because it is a biometric factor, and thus a different type of factor. An access card, RFID, and USB thumb drive are all items in possession of a user, the same as an RSA token, and as such would not be appropriate.
