You have 1 hour to complete this paper You must achieve 13 or more out of possible 20 marks (65%) to pass this exam Name Email Enter your DOB (dd/mm/yyyy) 1. What is an important concern for the customer in multi-tenant environments? Availability Network bandwidth Network latency Security None 2. Virtualization is a key architectural feature of Cloud computing. What is another one of these key characteristics of Cloud computing? the use of secured access the use of Service Level Agreements the use of standard protocol the use of the Internet None 3. Where did the Internet begin? a cluster of cooperating universities in the USA computer hobbyists the CIA the Department of Defense of the USA None 4. What is a benefit of Cloud Computing for IT staff? higher payment of IT staff involved in Cloud Computing less interruption of work caused by users asking for support less knowledge needed: Cloud Computing does not require special skills lower stress levels: less worry about normal daily activities like making back-ups None 5. What is a correct description of a Thin Client? a Client computer without a screen a mobile phone with access to the Internet a Personal Computer without a hard drive a user terminal without a processor None 6. What is Multi-tenancy? An architecture in which a single instance of a software application serves multiple customers. An architecture in which each customer has their own software instance. A way of thinking in terms of services and service-based development and the outcomes Of services. The act of creating a virtual (rather than actual) version of something, including (But not limited to) a virtual computer hardware platform, operating system (OS), Storage device or computer network resources. None 7. The ISO/IEC 20000-1:2011 standard requires that ISO/IEC 20000 processes are documented. Who needs to show that they are familiar with the processes and adhere to the procedures and working instructions? Only the organization, because they are responsible for the processes. Only the Cloud service provider, because they take over all responsibility. Both the organization and the Cloud service provider, because they share responsibility. Neither the organization, nor the Cloud service provider, because the processes within Cloud computing are outside the scope of ISO/IEC 20000. None 8. Which service model allows the customer to choose more layers in the Computing architecture? Infrastructure as a Service (IaaS) Platform as a Service (PaaS) Software as a Service (SaaS) There is no difference between the service models. None 9. What is an example of a single purpose environment? any application on any server interface to a large computer interface to large storage Mainframe None 10. What is Federation in Identity management? cloud-based Identity management enabling single sign-on (SSO) for multiple systems systems in the Cloud sharing information about the identity of users the cloud of all systems accessible by a single user the identity of a group of users sharing the same cloud resources None 11. What is the benefit of storage availability in the Cloud? Additional storage does not require budget for new large storage devices. Storage in the Cloud has a higher availability than storage devices in the Local Area Network (LAN). Storage in the Cloud has shorter access times than storage in the LAN. Storage in the Cloud is easier to protect against intrusion. None 12. Which question do you not have to ask when moving your local Cloud network to a hybrid environment? How do I test if my provider has everything under control? How well is my data protected against theft? What happens to my data when I’m not using it? What will my customers notice from the move? None 13. What is Abuse of Cloud Services? An intolerable system slowdown leaves all of the legitimate service users confused And angry as to why the service isn’t responding. Cloud provider may not only host your data and applications, but also malicious software. Moving into the Cloud may make it more difficult for organizations to prove their Compliance to legislation and regulations during external audits. Some of the cloud providers staff or sub-contractor staff may be untrustworthy. None 14. Why is a trial period needed when considering to use Software as a Service (SaaS)? to establish the required bandwidth for using the cloud services to evaluate whether the cloud services will be useful to find out whether the vendor will meet the Service level agreement (SLA) to have time to accommodate the local network to use of the new services None 15. Why are standards used in Cloud Computing? Standards provide compliance. Standards provide location independence. Standards provide portability. Standards provide security. None 16. What is a major limitation in using applications on mobile platforms? lack of applications available for mobile platforms limited memory of mobile phones not all applications are available for all mobile platforms. there is no enterprise applications available for the mobile platforms None 17. What is an important limitation of Cloud Computing? automation increased costs privacy shared resources None 18. In a cloud environment, consumers become dependent upon providers for products and services. What is a term used to describe the difficulties in migrating a software application from one provider to another? Data conversion plan Loyalty program Marketing strategy Vendor lock-in None 19. What is a staffing benefit of Cloud Computing? fewer IT-staff higher recruitment managed services self-service None 20. What is a Virtual Private Network (VPN)? a secured connection for remote access to a Local Area Network (LAN) a secured private cloud for a single user a virtual network device for private purposes an operating system for private network systems None 1 out of 5 Time is Up!
