Pass the GAQM: Management CITM-001 Questions and answers with ValidTests

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.

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.

Information processing is the exchange of information among people, processes and systems within an organization1. It is crucial for achieving business goals, making informed decisions and working efficiently2. To effectively deliver the information needed to decision makers, Management Information Systems (MIS) need to have the necessary components to collect, process, store and retrieve the information whenever it is needed3. The success of information processing depends on the alignment of MIS with the organizational strategy, structure and culture3. Therefore, the two management departments that are responsible for the success of information processing are top management and middle management. Top management is responsible for setting the vision, mission, goals and objectives of the organization, as well as defining the policies and procedures that guide the information flows3. Middle management is responsible for implementing the plans and strategies of top management, as well as coordinating and supervising the activities of lower-level managers and employees3. Both top and middle management need to ensure that the information systems are aligned with the business needs, and that the information flows are effective, efficient and secure3. References: 1: Practices for managing information flows within organizations12: Management Information Systems (MIS): Definition and How It Works23: Information management3

 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.

An ER diagram (Entity-Relationship diagram) is a type of diagram that consists of object types and relationships. An object type is a category of objects that share common attributes and behaviors, such as a class, an entity, or a component. A relationship is a connection or association between two or more object types, such as an inheritance, an aggregation, or a dependency. An ER diagram is used to model the structure and semantics of a system, such as a database, a software system, or a business domain. An ER diagram can show the cardinality, optionality, and constraints of the relationships, as well as the attributes and operations of the object types. References: What is an Entity Relationship Diagram (ERD)?, Object Diagrams | Unified Modeling Language (UML), The Easy Guide to UML Class Diagrams | Class Diagram Tutorial, Class diagrams vs Object diagrams in UML

Explicit knowledge is the type of knowledge that can be easily articulated, expressed, and recorded in the form of text, number, symbol, code, formula, or musical note. It is the knowledge that is based on facts, data, and rules that can be shared and communicated. Examples of explicit knowledge are company policies, process documents, research reports, etc12345 References:

Information can be defined as data that has been processed or organized in a meaningful way that reduces uncertainty. Information can be either tangible or intangible, depending on whether it has a physical form or not. For example, a printed report is tangible information, while an email is intangible information. Information can also be static or dynamic, depending on whether it changes over time or not. For example, a historical record is static information, while a stock price is dynamic information. However, the question asks for the two entities that define information, not the two attributes that describe information. Therefore, the correct answer is A and B, tangible and intangible. References: Sample Exam - GAQM, page 2, question 6.

 A relation is a type of association that describes how two or more entities are related to each other. A relation can have different properties, such as cardinality, optionality, and directionality, that specify the nature and constraints of the association. A relation can also have attributes that store information about the association. For example, a relation between Employee and Project entities can have an attribute called Role that indicates the role of each employee in each project. A relation can be represented by a line connecting the entities in an entity-relationship diagram (ERD). References: Association and Associative entity - IBM, When to use Associative entities? - Stack Overflow, [Entity-Relationship Model - Tutorialspoint].

A malicious program that records a user’s keystrokes is an example of a Trojan horse. A Trojan horse is a type of malware that masquerades as a legitimate file or application, but secretly performs malicious actions in the background. A Trojan horse can be used to install other malware, such as keyloggers, on the victim’s device. A keylogger is a specific type of Trojan horse that captures and sends the user’skeystrokes to a remote attacker, who can use them to steal sensitive information, such as passwords, credit card numbers, or personal data.

The other options are not correct because:

Adware is a type of malware that displays unwanted advertisements on the user’s device, often redirecting them to malicious websites or installing more malware. Adware does not necessarily record the user’s keystrokes, although some adware may have keylogging capabilities.

An anti-virus program is a software that protects the user’s device from malware, such as viruses, worms, ransomware, spyware, etc. An anti-virus program does not record the user’s keystrokes, but rather scans and removes any malicious programs that may do so.

A performance monitor is a software that measures and displays the performance of the user’s device, such as CPU usage, memory usage, disk space, network traffic, etc. A performance monitor does not record the user’s keystrokes, but rather provides useful information for troubleshooting or optimizing the device.

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?
