What is meant by Virtualization?

Virtualization means that data does not exist anywhere.

Virtualization is a method to combine more computing power onto one server

Virtualization is a method to combine multiple computer environments onto one server

Virtualization means that no real computer system is needed to distribute cloud solutions.

What might be considered an advantage for someone storing valuables in a bank in comparison to someone storing data in the Cloud?

The bank uses physical measures to protect your valuables

The bank has better protection against fires and floods.

. The bank has better opening hours.

In identity management, how might location information be used?

. to determine the user’s native language

to determine whether the user is connected via a mobile platform

to provide advertisements for local restaurants, determined by GPS

to provide the correct version of the application for the user’s operating system

digital identity

group management

role management

separation of duties

Restricting access to systems/applications based on time is part of which Triple-A security cornerstone?

Accounting

Application

C. Authentication

Authorization

How might moving to Cloud computing enhance user’s ongoing experience of software applications?

by accomplishing quick and efficient application updates

by increasing the access to information available on the Internet

by moving internal systems with performance problems to the Cloud
