CITM-001 Certified Information Technology Manager (CITM) Questions and Answers

The second step in System Analysis is to conduct a feasibility study, which is an assessment of the technical, economic, legal, operational, and schedule aspects of the proposed system. A feasibility study helps to determine whether the system is viable, beneficial, and achievable within the given constraints and resources. A feasibility study also helps to identify the risks, costs, benefits, and alternatives of the system. References: 1, 2, 3

Rotational delay is the time it takes for the desired sector of the disk to rotate under the read-write head after the head has been positioned at the correct track. It depends on the rotational speed of the disk and the position of the sector relative to the head. It is one of the components of data access delay, along with seek time, transmission delay, and processing delay. References: Delays in Computer Network - GeeksforGeeks, Access time - Wikipedia

Tangible costs are those that can be easily quantified and measured, such as direct expenses or physical assets. However, in some cases, tangible costs savings can be difficult to estimatebecause they depend on various factors, such as the expected life cycle of the asset, the depreciation rate, the maintenance costs, the opportunity costs, and the market conditions. For example, if a company invests in a new production machine, the tangible cost savings would be the difference between the cost of the old machine and the cost of the new machine, plus the additional benefits of the new machine, such as higher output, lower energy consumption, and improved quality. However, these benefits may not be easy to measure or predict, especially in the long term. Therefore, tangible costs savings can be difficult to estimate in some cases. References: Tangible Cost: Meaning and Difference From Intangible Costs - Investopedia, What Are Tangible Costs?

Data warehousing and data mining are closely related technologies that support business intelligence and analytics. Data warehousing is the process of collecting, integrating, and organizing data from various sources into a centralized repository that can support complex queries and analysis. Data mining is the process of applying various techniques and algorithms to extract useful information and patterns from the data stored in the data warehouse. Data mining can help discover hidden relationships, trends, anomalies, and insights that can improve decision making and performance. One of the main reasons for building a data warehouse is to enable data mining, as data warehouses provide a consistent, reliable, and comprehensive source of data that can be mined for various purposes. Data warehouses also facilitate data mining by providing data quality, data cleansing, data transformation, data aggregation, and data indexing services that can enhance the accuracy and efficiency of data mining. Data warehouses and data mining are complementary technologies that work together to deliver business value and competitive advantage. References: Data Warehousing and Data Mining 101, Data Warehousing and Data Mining - Topcoder, Difference between Data Warehousing and Data Mining

Development cost is the type of cost that is considered as actual costs of analysis, design, and installation for the system. Development cost includes the expenses incurred during the planning, designing, building, testing, and deploying of a system. Development cost is usually estimated before the start of a project and is used to measure the feasibility and profitability of a system. Development cost is also used to monitor the progress and performance of a project and to control the scope and quality of a system. References: CITM Course Outline, Module 4, Corporate IT Strategy, page 9. CITM Training Course, Cost, page 14. CITM Certification Overview, Exam Information, Course Outline, Module 4.

 System analysis is the process of understanding problems and needs and arriving at solutions that meet them. It involves identifying, defining, and specifying the requirements of a system, as well as designing, developing, testing, and implementing the system. According to Wikipedia1, system analysis can be broken into five phases: scope definition, problem analysis, requirements analysis, logical design, and physical design. However, according to MasterStart2, there are seven stages of system development life cycle (SDLC), which include planning, requirements analysis, designing, development and testing, implementation, documentation, and evaluation. Therefore, depending on the perspective and the methodology, system analysis can involve three to seven stages, but the most common number is three: requirements analysis, logical design, and physical design. References: Wikipedia; MasterStart

Organizations are linked extensively to increase their efficiency and effectiveness in achieving their goals. By reducing cycle times, organizations can deliver their products or services faster and more responsively to their customers. By improving accuracy, organizations can reduce errors, waste, and rework, and enhance their quality and reliability. These outcomes can also increase the capability of the organization to meet the changing needs and expectations of the market and the stakeholders. References: Sample Exam - GAQM, page 1, question 1; The Future of Flexibility at Work, paragraph 4.

A byte is the smallest unit of data storage that consists of eight bits. A bit is a binary digit that can have two values: 0 or 1. A byte can store one character, such as a letter, a number, or a symbol. An octet is another name for a byte, but it is not commonly used. A character is a symbol that represents a letter, a digit, or a punctuation mark, but it is not a unit of data storage. A field is a group of bytes that stores a specific type of data, such as a name, a date, or a number, but it is not the smallest unit of data storage. References: Data Storage Units of Measurement Table, What are the units of measurements for data storage?, Data Storage Units

Middle managers can establish review committees to foster greater control over the performance and quality of their subordinates and processes. Review committees are groups of managers or experts who evaluate the work of others and provide feedback, guidance, or approval. Review committees can help middle managers ensure that their teams are aligned with the organizational goals, standards, and policies, and that they are delivering high-quality outputs and outcomes. Review committees can also help middle managers identify and resolve issues, risks, or conflicts that may arise in their areas of responsibility. Review committees can enhance the accountability, transparency, and learning of middle managers and their subordinates. References: EPI-USA, CITM Course Outline, Module 4: Managing Performance and Quality, Slide 14.

A macro virus is a virus that is written in a macro language, which is a programming language embedded inside a software application, such as word processors and spreadsheet applications. A macro virus can attach itself to a file or template and run automatically when the file is opened or closed, without the user’s knowledge. A macro virus can infect any system that supports macros, regardless of the operating system. A macro virus can spread quickly by infecting other documents and templates, and may cause damage to the computer and its applications123 References:

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. References:

Managerial control decisions are those that involve measuring and correcting the performance of activities of subordinates to ensure that the enterprise objectives and plans are being accomplished. Managerial control decisions fall between operational and strategic planning because they are concerned with both executing the strategy and tracking its progress. Operational control decisions are those that focus on the efficiency and effectiveness of specific processes, tasks, and functions. Strategic control decisions are those that evaluate the alignment of the strategy with the external and internal environment, and make adjustments if necessary. References: Managerial Control: Definition, Features, Scope, and Process, Types and Levels of Control – Principles of Management, The Control Function of Management - MIT Sloan Management Review

 An international strategy is much like the multinational strategy as there are autonomous local subsidiaries that operate independently from the headquarters. However, unlike the multidomestic strategy, the international strategy does not involve extensive customization of products and services to local markets. Instead, the international strategy relies on offering a standardized product worldwide with little or no change. The international strategy is suitable for firms that face low pressure for global integration and low pressure for local responsiveness. Examples of firms pursuing an international strategy are Harley Davidson, Starbucks, and Rolex. References: International Business Strategy EXPLAINED with EXAMPLES | B2U, 9.4 Types of International Strategies – Strategic Management

In a multi-user design, one group usually develops the systems for use by another group. This is because different groups of users may have different needs, preferences, and expectations for the system. For example, a system that is designed for the accounting department may not be suitable for the marketing department, or a system that is designed for the managers may not be user-friendly for the employees. Therefore, a multi-user design involves identifying the target users, analyzing their requirements, designing the system accordingly, and testing the system with the users. A multi-user design also requires coordination and communication among the developers and the users, as well as among different user groups, to ensure that the system meets the needs and expectations of all stakeholders. References: Multi-User Operating System - GeeksforGeeks; Multiple Group Design: Definition & Examples - Study.com; Chapter 10: Information Systems Development

Systems analysis is the second step in the Systems Design Life Cycle (SDLC), which is a process for planning, creating, testing, and deploying an information system. Systems analysis involves gathering and analyzing the requirements of the system, such as the user needs, the business objectives, and the functional specifications. Systems analysis also involves modeling the system using various techniques, such as data flow diagrams, entity-relationship diagrams, and use case diagrams. Systems analysis helps to define the scope and boundaries of the system, as well as the inputs, outputs, processes, and data structures. Systems analysis is essential for ensuring that the system design meets the expectations and needs of the stakeholders. References: 1, 2, 3, 4

A logic bomb is a type of malicious code that is inserted into a software program and remains dormant until a specific condition or event occurs, such as a certain date, time, or user action. When the condition is met, the logic bomb activates and executes its harmful payload, which can range from deleting or corrupting data, to displaying unwanted messages, to crashing the system. Logic bombs are often used by disgruntled employees or hackers to sabotage an organization’s IT infrastructure or to extort money or information. Logic bombs are different from keyloggers, spam, and viruses, which are explained below:

• A keylogger is a software or hardware device that records every keystroke made by a user on a computer or mobile device, usually for the purpose of stealing passwords, personal information, or other sensitive data. Keyloggers can be installed by hackers through phishing, trojan viruses, or physical access to the device. Keyloggers do not wait for a specific condition to activate, but rather run continuously in the background and transmit the captured data to a remote server or storage device.
• Spam is any kind of unwanted, unsolicited, or irrelevant digital communication that is sent or posted to a large number of recipients or places, typically for the purposes of advertising, phishing, spreading malware, or disrupting normal operations. Spam can be delivered via email,text message, phone call, or social media. Spam does not contain hidden code that executes a harmful action, but rather relies on the user’s response or interaction to achieve its goal, such as clicking a link, opening an attachment, or providing personal information.
• A virus is a type of malware that infects a computer or mobile device by attaching itself to another program or file and replicating itself when the host program or file is executed. A virus can have various harmful effects, such as deleting or modifying data, consuming system resources, displaying unwanted messages, or opening backdoors for hackers. A virus can spread from one device to another through networks, removable media, or email attachments. A virus does not require a specific condition to activate, but rather runs whenever the infected program or file is executed.

Lower level management, also known as supervisory or operational management, is the lowest tier of the managerial hierarchy. It consists of managers who oversee the work of employees and report to middle level managers. Lower level managers can make use of the managerial hierarchy to obtain approvals or additional guidance from their superiors when they face problems or challenges that are beyond their authority or expertise. The managerial hierarchy also helps lower level managers to communicate and coordinate with other managers and departments within the organization. References: 3, CITM Study Guide, Chapter 2: Organizational Structure and Design, Section 2.1: Types of Organizational Structures, Page 18.

The select clause corresponds to the projection operation of the relational algebra. It is used to list the attributes desired in the result of a query. For example, the query select name, age from student will return the name and age attributes of all tuples in the student relation12. References: 1: CSE132A F05 SQLpart1 - University of California, San Diego 2: Basic Operations - RDBMS Questions and Answers - Sanfoundry

According to the CITM course outline1, there are five data collection techniques that are commonly used in business analytics. They are:

• Observations: This technique involves watching and recording the behavior, actions, or events of interest. Observations can be either direct or indirect, structured or unstructured, participant or non-participant.
• Interviews: This technique involves asking questions to individuals or groups of people who have relevant knowledge or experience on the topic. Interviews can be either structured, semi-structured, or unstructured, depending on the level of flexibility and standardization of the questions.
• Surveys: This technique involves administering a set of questions to a sample of respondents who represent the population of interest. Surveys can be either quantitative or qualitative, depending on the type and scale of the questions.
• Focus groups: This technique involves gathering a small group of people who share some common characteristics or opinions on the topic and facilitating a discussion among them. Focus groups can be used to explore attitudes, perceptions, feelings, or preferences of the participants.
• Documents: This technique involves reviewing and analyzing existing documents or records that are relevant to the topic. Documents can be either primary or secondary, depending on the source and authenticity of the information.

RAM, or Random Access Memory, is the best fit for the statement because it is the main memory of the computer system and is volatile. RAM is a type of computer memory that is used to store data that is currently being used by the computer’s operating system and applications. RAM is volatile because it loses its contents when the power supply to the computer is turned off or interrupted. RAM is also faster and more expensive than other types of memory, such as ROM, PROM, or hard disk, which are non-volatile and can retain data without power. RAM isdivided into two types: static RAM (SRAM) and dynamic RAM (DRAM), which differ in their speed, power consumption, and design. References

Temporary work groups are formed for a specific purpose and usually dissolve after the task is completed. They may include employees of customers, suppliers or partner corporations who collaborate with the organization to achieve a common goal. For example, a temporary work group may be created to develop a new product, launch a marketing campaign, or implement a new system. Temporary work groups can benefit from the diverse perspectives, skills, and resources of their members, as well as foster innovation and learning. References: CITM Course Outline, Flexible Work Arrangements: Types and Benefits
