A company’s business model was changed to provide more web presence and now its ERM
software is no longer able to support the security needs of the company. The current data center
will continue to provide network and security services. Which of the following network elements
would be used to support the new business model?
A.
Software as a Service
B.
DMZ
C.
Remote access support
D.
Infrastructure as a Service
Explanation:
Key words: WEB Presence & ERM
• ERM (enterprise resource management) describes software that lets an enterprise manage user access to its network resources efficiently.
• ERM software generally lets a user sign on to different enterprise systems and applications using the same password.
• ERM software makes it easy for the enterprise to control and keep track of which systems and resources each user has access to, and provides consistent standards for creating and changing passwords.
• One system administrator can usually manage user access to all platforms – UNIX, mainframe, Windows NT, and so forth – and to the applications on these platforms that require controlled access.
PROCESS OF ELIMINATION:
B – “DMZ” will segregate WEB Servers, but will not fix the issues with ERM
C-“Remote access support “is simply daft
D- IaaS – Infrastructure as a Service. They already are catering for the Infrastructure (The current data centre will continue to provide network and security services)
So the best answer is: A
Software as a Service (SaaS) allows for on-demand online access to specific software applications or suites without having to install it locally. This will allow the data centre to continue providing network and security services.
