What is a facility used to house management information systems and associated components, such as telecommunications and storage systems? a) Call centre b) Data centre c) Delivery base d) Central centre   MULTIPLE CHOICE ANSWERS 1. B Enterprise architecture is both dynamic and continually changing. 2. A The three primary areas that enterprise architecture supports are operations, change and sustainability (the environment). 3. C Backup is an exact copy of a system's information, where recovery is the ability to get a system up and running in the event of a system crash or failure. 4. B Within the area of support provided by information infrastructure, the disaster recovery area has the ability to recover information or systems in the event of a catastrophic disaster. 5. D Fault tolerance is the ability for a system to respond to unexpected failures or system crashes as the backup system immediately and automatically takes over with no loss of service. 6. B The business continuity planning (BCP) system includes these factors: (1) identifying critical systems, business processes, and the maximum amount of time the company can continue to operate without functioning systems; (2) identifying a detailed order in which functional areas should be restored; and (3) ensuring the most critical are focused on first. 7. A The definition of maintainability (or flexibility) – how quickly a system can transform to support environmental changes. 8. C The definition of reliability (or accuracy) – a measure of whether a system is functioning correctly and providing accurate information. 9. A When building a scalable system that can support any new company development, the key factors to consider are anticipating expected and unexpected growth. 10. A The definition of usability – the degree to which a system is easy to learn and efficient and satisfying to use. 11. C Three pressures driving sustainable MIS infrastructures include increased electronic waste, increased energy waste and increased carbon emissions. 12. D Grid computing takes advantage of the available 75 per cent of unused processing power of a computer and links thousands of individual computers around the world to create a virtual supercomputer that can process intensive tasks. 13. C Cloud computing may change the way businesses operate, as well as the way people interact with technology. 14. B Infrastructure as a Service (IaaS), Software as a Service (SaaS), Platform as a Service (PaaS). 15. B The definition of data centre – a facility used to house management information systems and associated components, such as telecommunications and storage systems.   REVIEW QUESTIONS FROM CHAPTER 7 OF THE BALTZAN ET AL.
