GAQM Certified Information Technology Manager Exam CITM-001 CITM Exam Practice Test

Answer : A

Conversion is the process of changing the existing system to the new system. It involves transferring data, installing hardware and software, training users, and decommissioning the old system.Conversion is the ninth step in the Systems Design Life Cycle, according to the CITM study guide1Reference:1CITM Study Guide, Chapter 4: System Development Life Cycle, page 4-14.

Answer : B

Interviews are a user-oriented design technique that allows the systems analyst to spend a great deal of time with the users, understanding their needs, preferences, expectations, and problems. Interviews can be structured, semi-structured, or unstructured, depending on the level of flexibility and depth required. Interviews can provide rich and detailed insights into the users' context, goals, tasks, and pain points, as well as their feedback and suggestions for improvement. Interviews can also help to establish rapport and trust between the systems analyst and the users, which can facilitate the design process and user acceptance.Reference:User-Centered Design Basics | Usability.gov,User-centered design: Definition, examples, and tips

Answer : C

A client-server environment is a type of distributed system that divides the application logic into three layers: presentation, application, and data. The presentation layer is responsible for the user interface and interaction, the application layer contains the business logic and functionality, and the data layer manages the storage and retrieval of data.Each layer can run on a different machine or server, allowing for scalability, modularity, and security1234Reference:

According to the Certified IT Manager (CITM) course outline, there are nine stages in a systems design life-cycle. They are: 1. Initiation, 2. Concept Development, 3. Planning, 4. Requirements Analysis, 5. Design, 6. Development, 7. Integration and Test, 8. Implementation, and 9. Operations and Maintenance. Each stage has its own objectives, deliverables, and activities that ensure a systematic and effective approach to system development.Reference:CITM Course Outline,System Development Life Cycle - GeeksforGeeks,Systems development life cycle - Wikipedia

Answer : A

Functional design is a design approach that focuses on the functionality and performance of a system, rather than its structure or appearance. Functional design usually begins with specifying the desired output, such as the goals, objectives, and requirements of the system, and then derives the input, processes, and data needed to achieve the output. Functional design can be applied to various types of systems, such as software, hardware, or business processes. Functional design is often contrasted with other design approaches, such as organizational design, object-oriented design, and structured design, which have different emphases and methods.Reference:

According to the CITM certification, there are six trends that have drastically altered the way organizations use technology. These are:

Cloud computing: The delivery of computing services over the internet, such as servers, storage, databases, networking, software, analytics, and intelligence. Cloud computing enables organizations to access scalable, flexible, and cost-effective IT resources on demand.

Big data and analytics: The collection, processing, and analysis of large and complex data sets to generate insights and value. Big data and analytics enable organizations to improve decision making, optimize operations, enhance customer experience, and create new products and services.

Social media and collaboration: The use of online platforms and tools to communicate, share, and interact with others. Social media and collaboration enable organizations to engage with customers, employees, partners, and stakeholders, as well as to foster innovation and knowledge sharing.

Mobile and wireless: The use of devices and networks that allow users to access information and services anytime and anywhere. Mobile and wireless enable organizations to extend their reach, improve productivity, and offer convenience and personalization.

Internet of things (IoT): The network of physical objects that are embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems. IoT enables organizations to monitor and control their assets, processes, and environments, as well as to create new business models and opportunities.

Cybersecurity: The protection of information systems and data from unauthorized access, use, disclosure, modification, or destruction. Cybersecurity enables organizations to safeguard their assets, reputation, and trust, as well as to comply with laws and regulations.

Answer : A, B, D

Distributed databases provide several advantages over centralized databases, including improved scalability, availability, performance, flexibility, fault tolerance, and security1. Here are some of the advantages of distributed databases:

Increased availability: Distributed databases can tolerate failures of individual nodes or sites without affecting the overall system functionality. Users can access data from other sites if their local site is down or unreachable.Data replication and backup mechanisms can also enhance data availability and recovery2.

Easier expansion: Distributed databases can be scaled horizontally by adding more nodes to the network. This allows for increased capacity and performance as data and user demand grow.Adding new sites or units to the distributed system does not require significant efforts or disruption in the existing functions2.

Improved performance: Distributed databases can offer faster response and lower communication costs by locating data near the users who normally use that data. Distributed query processing and transaction management can also optimize the use of network and computing resources.Furthermore, distributed databases can exploit the parallelism of multiple nodes to execute operations concurrently13.
