WGU Introduction to IT Sample Questions (Q77-Q82):

NEW QUESTION # 77
Which motherboard component is used for short-term storage of data?

Answer: B

Explanation:
*RAM (Random Access Memory) is the motherboard component used for short-term storage of data.
*RAM is a type of computer memory that can be read and written. It serves as temporary storage for data that the CPU (Central Processing Unit) needs to access quickly.
*When you run programs or open files, the data is loaded into RAM from storage devices (such as hard drives or SSDs). The CPU can then access this data rapidly, allowing for efficient execution of tasks.
*Unlike permanent storage (such as hard drives), RAM is volatile, meaning its contents are lost when the computer is powered off or restarted.
*RAM is crucial for overall system performance. The more RAM a computer has, the better it can handle multitasking, large applications, and data-intensive tasks.
*In summary, RAM provides fast, temporary storage for data that the CPU actively uses during program execution.

NEW QUESTION # 78
Based on an analysis of a company's needs, a database should be installed so that data resides on different machines, often in entirely different locations. What is the name of the database that satisfies this need?

Answer: B

Explanation:
A distributed database is a database in which data is stored across multiple computers or servers rather than in a single central location. These machines may be in the same building, across a campus, or in different geographic regions. In Information Technology and database design, distributed databases are used to improve availability, fault tolerance, scalability, and performance by placing data closer to users and by reducing reliance on one server. The distributed database management system coordinates storage, replication, and query processing so that users can access data as if it were a single database, even though it is physically spread out. This model supports business continuity because if one site fails, another site can continue serving requests depending on the replication strategy. Relational and NoSQL describe data models and query approaches, while cloud describes a deployment environment that can host many types of databases, including distributed ones. Because the defining requirement here is data stored on different machines and locations, the correct answer is a distributed database.


NEW QUESTION # 79
A programmer needs to create a variable that holds the number of lightbulbs in a pack. What is the name of the data type that should be used?

Answer: B

Explanation:
A variable that holds the number of lightbulbs in a pack should use an integer data type because the value is a count expressed as a whole number. In programming and database contexts, integers are used for quantities that do not require fractions, such as number of items, units sold, students in a class, or days in a month.
Choosing an integer type supports efficient memory usage, accurate arithmetic for counting, and proper validation rules such as preventing non-whole values. A Boolean type would be incorrect because it can store only two states, such as true or false. Floating-point types are designed for values that may include decimals, such as measurements or scientific values, and can introduce rounding behavior that is unnecessary for simple counts. Character data is used for single symbols or letters, not numerical counts intended for arithmetic. In Information Technology best practices, selecting the most appropriate data type reduces errors and improves data integrity. Therefore, the correct data type for the number of lightbulbs in a pack is integer.


NEW QUESTION # 80
What is scope creep?

Answer: A

Explanation:
Scope creep refers to the uncontrolled and often unmanageable growth of a project's requirements or 'scope' once it's underway1. Here's a breakdown:
1.Project Scope:
oProject scope defines the outline of requirements and deliverables for a project.
oIt's usually established at the beginning of project planning and captured in project plans, roadmaps, or briefs.
2.What Is Scope Creep?
oScope creep occurs when the asks and deliverables exceed the pre-set project scope.
oStakeholders add more deliverables or push back deadlines, leading to changes beyond the original plan.
oThese changes can delay the project timeline, increase costs, and impact quality.
3.Examples of Scope Creep:
oMissed Deadlines: When team leads extend deadlines without clear instructions, causing work to never feel
"done."
oExternal Changes: Unexpected events (e.g., macroeconomic shifts, natural disasters) lead to extra work and adjustments.
oResource Constraints: Trying to achieve the same goals with fewer resources, affecting overall project status.
4.Preventing Scope Creep:
oClear Communication: Define scope upfront and communicate changes transparently.
oScope Management: Regularly review and manage scope throughout the project.
oAgile Methods: Use Agile practices to adapt to changes while maintaining focus on objectives.
Remember, managing scope effectively is crucial for project success!

NEW QUESTION # 81
What is the type of software that has no intellectual property protections?

Answer: C

Explanation:
Public domain software has no intellectual property protections such as copyright restrictions. In Information Technology licensing concepts, public domain means the creator has waived copyright or the copyright has expired, so the work can be used freely by anyone. Users can copy, modify, distribute, and reuse the software without needing permission and without paying licensing fees. This is different from freeware, which is free to use but still copyrighted and subject to license limitations. It is also different from shareware, which is typically copyrighted software released as a trial or limited version to encourage purchase of the full product.
Closed-source refers to a model where the source code is not provided publicly, but it does not mean there are no intellectual property protections. The key phrase in the question is no intellectual property protections, which aligns directly with public domain status. Therefore, the correct answer is public domain.
