WGU Introduction to IT 認定 Introduction-to-IT 試験問題 (Q135-Q140):

質問 # 135
What is the arrangement of network devices in a mesh topology?

正解：A

解説：
In a mesh topology, every device is connected to every other device. In Information Technology networking fundamentals, a full mesh topology provides multiple direct paths between nodes, which improves redundancy and fault tolerance. If one connection fails, data can often be rerouted through other links, reducing the chance of total network disruption. This makes mesh designs valuable for mission-critical environments where high availability is required. However, the number of connections grows quickly as devices increase, which raises cost, complexity, and management overhead. The other options describe different topologies: a star topology connects all devices to a central device such as a switch, a bus topology connects devices to a single shared communication line, and a ring topology connects each device to exactly two others, forming a loop. Because the defining feature of a mesh is the extensive interconnection among devices, the correct description is that every device is connected to every other device. Therefore, the correct answer is option C.


質問 # 136
One database field needs to be restricted to only those values that are single alphanumeric symbols. Which data type should be used?

正解：A

解説：
A field restricted to single alphanumeric symbols should use the character data type because it is designed to store exactly one character. Alphanumeric symbols include letters A through Z and digits 0 through 9, and these are naturally represented as individual characters. In Information Technology and database systems, selecting a character type allows the designer to enforce a fixed length of one, which helps maintain data integrity by preventing longer entries. An integer type is used for whole numbers and would not properly handle letters, while floating point is for decimal values and is also inappropriate for single symbols. A character string type can store multiple characters, which would allow inputs longer than one symbol unless additional constraints are applied. Using the character type is therefore the most direct and standard approach for storing one letter or digit, such as a middle initial, a grade code, or a single-character category label.
Therefore, the correct data type is character.


質問 # 137
What is a step for considering risk during the planning phase of project management?

正解：A

解説：
Risk planning in project management includes identifying risks and then analyzing and prioritizing them so the team can focus on the most serious threats. A standard step taught in Information Technology project management is prioritizing risks by severity and likelihood. Severity reflects the impact on scope, cost, schedule, security, or quality if the risk occurs, while likelihood reflects the probability of occurrence.
Combining these factors helps create a risk matrix and guides decisions about mitigation strategies, contingency plans, and resource allocation. Comparing project progress to milestones is part of monitoring and controlling during execution, not risk planning. Listing each possible cause of failure is related to risk identification, but on its own it does not complete the analysis step that determines which risks matter most.
Establishing clear and attainable goals is part of initiation and planning, but it is not specifically a risk analysis technique. Because the question asks for a step for considering risk during planning, prioritizing by severity and likelihood is the best match. Therefore, the correct answer is option A.


質問 # 138
An IT department employee is identifying the Boolean data in a system. What is one example of this type of data?

正解：D

解説：
Boolean data represents a logical value with only two possible states, typically true or false. In Information Technology, Boolean types are foundational for conditions, comparisons, control flow, and database fields that store yes-or-no style information. The example, "Whether a number is positive or not," fits Boolean data because the statement can be evaluated as true if the number is greater than zero, or false otherwise. This two- state characteristic is exactly what defines Boolean logic. The other options describe different data types: the first letter of a last name is a character, a full last name is a character string, and the price of gas in dollars and cents is numeric with decimals, typically stored as a floating-point or fixed-point decimal type. Boolean fields are widely used in systems for flags such as active or inactive, approved or not approved, and eligible or not eligible. Therefore, the correct example of Boolean data is whether a number is positive or not.


質問 # 139
What is the goal in improving uptime?

正解：A

解説：
The goal of improving uptime is increasing the portion of time for which systems are operational. In Information Technology operations and service management, uptime measures availability, meaning how consistently an information system is running and accessible when users need it. High uptime is critical for business continuity, customer satisfaction, and meeting service level agreements. Improving uptime involves reducing both planned downtime, such as maintenance windows, and unplanned downtime, such as hardware failures, software crashes, network outages, or cyberattacks. Common strategies include redundancy, failover clustering, monitoring and alerting, preventative maintenance, patch management, and resilient infrastructure design. Increasing time between maintenance events can contribute indirectly, but it is not the definition of uptime improvement. Faster startup processes may reduce downtime duration during restarts, but it is only one factor. Increasing the interval between backups could actually increase risk and does not improve availability. Since uptime is fundamentally the percentage of time systems remain available and functioning, the correct objective is to increase the portion of time the systems are operational. Therefore, the correct answer is option D.
