Infrastructure and Operations MCQs
Information Technology – Describes any equipment concerned with the capture, storage, transmission or presentation of information. Is referred to as ICT (Information Communications Technology), emphasizing the importance of communications. Here on MCQs.club we have prepared useful Multiple-Choice Questions (MCQs) on Infrastructure and Operations that fully cover MCQs on IT infrastructure questions, solved mcqs of information technology, IT infrastructure quiz. These IT infrastructure and emerging technologies quiz are useful for Professional Accountancy exams, Business management exams and Competitive exams.
- Information Technology –
- Describes any equipment concerned with the capture, storage, transmission or presentation of information.
- Is referred to as ICT (Information Communications Technology), emphasizing the importance of communications.
- Both A&B
- None
- Information systems (ISs) –
- Are the systems responsible for the provision of information for management.
- They incorporate IT, people, business processes and procedures used to manage the capture and communication of information.
- They involve complex and dynamic interaction between people, technology and process to ensure the delivery of appropriate and timely information to management.
- All of the above
- An effective IS (Information system) should have various logs that individuals examine regularly and take appropriate action on when necessary. Examples of logs include:
- Data entry staff should keep full details of each batch of work, with duration and errors.
- Backups, storage of data off-site should be logged
- Software application systems may generate their own logs of errors
- All of the above
- A security sub-system could maintain detailed logs of who did what and when and also if there were any attempted security violations.
- True
- False
- Quality management is the means by which IS (Information system) department-based processes are controlled, measured and improved. Areas of control for quality management include:
- Software development, maintenance and implementation
- Acquisition of hardware and software
- Security and Human resource management
- All of the above
- Which of the following is correct?
- The development and maintenance of comprehensive procedures by the IS department is evidence of effective governance of IT resources.
- Insistence on observance of processes and procedures is key to the effectiveness and efficiency of the IS organization.
- Both A&B
- None
- Various standards have emerged to assist IS (Information system) organizations in achieving an operational environment that is predictable, measurable and repeatable. Prominent examples of such include:
- The ISO 9000 series that govern software development processes.
- The ISO 9126 standard that focuses on the end result of good software processes
- The capability maturity model developed by the software engineering Institute
- All of the above
- ISO 9000 is a series of international standards for quality management systems. There are different sets of standards that companies can be registered to, including:
- ISO 9001
- ISO 9002
- ISO 9003
- All of the above
- IT service Management (ITSM) –
- Is the process of aligning enterprise IT services with business and a primary focus on the delivery of the best services to end user.
- IT service management deals with how IT resources and business practices in together, are delivered in such a way that the end-user experience the most desired result from the accessed IT resource, application, business process or an entire solution stack.
- Is built around processes and practices that gauges the end-to-end delivery of IT solutions rather than their development.
- All of the above
- Service level agreement (SLA) – is a written contract between a provider of a service and the consumer of the service. The purpose of SLA is to establish measurable targets of performance with the objective of achieving a common understanding of the nature of and levels of service required.
- The above is correct
- The above is incorrect
- IT management should have formal SLAs (Service level agreements) with all of their IT customers because these contracts provide:
- Defined levels of service
- Accountability for the service
- Evaluation criteria and a basis for improvement
- Performance criteria
- All of the above
- Upon completing the system design and program development, the software should be tested in various stages including:
- Program testing to check the logic of individual programs
- System testing to ensure program and file consistency as they are linked together and that they meet system requirements.
- Parallel testing of the new software simultaneously with the existing software.
- All of the above
- Procedures to prevent software license violations include:
- Centralizing control and automated distribution and the installation of software
- Requiring that all PCs be diskless workstations and have the workstations access-applications from a secured LAN
- Installing metering software on the LAN and require all PCs to access applications through the metered software
- All of the above
- Operating Systems (OS) – An operating system is a collection of programs that manage computer resources, provides a user interface, and runs applications. Classes of operating systems include:
- Single user, Multi user, Single tasking
- Multi-tasking single user, Multi-tasking multi-user
- Both A&B
- None
- Operating system – Single user:
- Means that only one user can use the facilities of the operating system at any one time. It somebody else wants to use the computer they have to wait until the person using it finishes.
- These are operating systems in which only one task can be performed by the operating system at any one time.
- This means that a user can sit in front of their computer and the computer appears to do many tasks at the same time.
- None
- Operating system – Single tasking:
- Means that only one user can use the facilities of the operating system at any one time. It somebody else wants to use the computer they have to wait until the person using it finishes.
- These are operating systems in which only one task can be performed by the operating system at any one time.
- This means that a user can sit in front of their computer and the computer appears to do many tasks at the same time.
- None
- Operating system – Multi-tasking Single user:
- Means that only one user can use the facilities of the operating system at any one time. It somebody else wants to use the computer they have to wait until the person using it finishes.
- These are operating systems in which only one task can be performed by the operating system at any one time.
- This means that a user can sit in front of their computer and the computer appears to do many tasks at the same time.
- None
- When purchasing hardware/software from a vendor, consideration should be given to the:
- Testimonials/visits to other users
- Provision for competitive bidding
- Analysis of bids against requirements
- Analysis of vendor financial condition
- All of the above
- The typical procedures and reports for monitoring the effective and efficient use of hardware include:
- Hardware Error Reports
- Availability Reports
- Utilization Reports
- All of the above
- Data management –
- It is the process that controls data buffering, performs I/O operations and deals with file management activities.
- It is a category of system software that is often a major component of the operating system.
- Both A&B
- None
- Data management file organizations that may be supported include:
- Sequential – one record is processed after another, from the beginning to the end of a file
- Indexed Sequential – Records are logically ordered according to a data-related key and can be accessed based on that key
- Direct Random Access – Records are addressed individually based on a non-data related key
- All of the above
- Capacity Management –
- It is the planning and monitoring of the computer resources to ensure that the available resources are being used efficiently and effectively.
- This requires that the expansion or reduction of resources takes place in parallel with overall business growth or reduction
- Both A&B
- None
- Capacity planning should include projections substantiated by past experience, which include both growths of existing business as well as future expansions. What information is required for the successful completion of this task?
