WGU Introduction to IT Sample Questions (Q88-Q93):

NEW QUESTION # 88
What is one purpose of business continuity planning?

Answer: D

Explanation:
Business continuity planning defines how an organization will resume and sustain essential services after a disruption. In Information Technology, disruptions can include cyberattacks, power failures, natural disasters, hardware failures, and human error. A continuity plan documents roles, responsibilities, communication steps, alternative processes, and recovery procedures so operations can continue at an acceptable level. It typically includes priorities for restoring critical systems first, along with targets such as recovery time objective and recovery point objective. Preventive maintenance is important for reducing failures, but it is not the primary purpose of business continuity planning. Ethical policy consistency is part of governance and compliance, not continuity planning. Eliminating downtime for nonessential services is unrealistic and not a central goal; continuity focuses on maintaining or restoring critical functions, and nonessential systems may remain offline during recovery. Because the plan's purpose is to guide an organization in restarting services and operations after an incident, the correct answer is helping define how to resume services after a disruption.


NEW QUESTION # 89
What is the primary role of the database administrator?

NEW QUESTION # 92
How are high-level languages different from machine language?

Answer: B

Explanation:
High-level languages and machine language (also known as machine code) serve different purposes in the world of programming. Let's explore the differences:
1.High-Level Languages:
oDefinition: High-level languages are programming languages that are designed to be more human-readable and user-friendly. Examples include C, C++, Java, Python, and Ruby.
oCharacteristics:
Abstraction: High-level languages provide a higher level of abstraction, allowing programmers to express complex logic using familiar syntax and natural language constructs.
Readability: Code written in high-level languages is easier for humans to understand because it resembles everyday language.
Platform Independence: High-level languages are platform-independent, meaning the same code can run on different operating systems with minimal modifications.
Compiler or Interpreter: High-level code is compiled or interpreted into machine code before execution.
oAdvantages:
Productivity: Developers can write code more quickly and efficiently.
Maintenance: Easier to maintain and debug due to readability.
Portability: Code can be moved across platforms.
oExample:
Python
# Example in Python
def greet(name):
print(f"Hello, {name}!")
greet("Alice")
2.Machine Language (Machine Code):
oDefinition: Machine language consists of binary instructions (0s and 1s) that directly correspond to the instructions executed by the computer's central processing unit (CPU).
oCharacteristics:
Low-Level: Machine language is the lowest level of programming language.
Binary Representation: Each instruction is represented as a sequence of binary digits (bits).
Specific to Hardware: Machine code is specific to the architecture of the computer (e.g., x86, ARM).
Direct Execution: The CPU executes machine instructions directly.
oAdvantages:
Efficiency: Machine code runs directly on the hardware, making it highly efficient.
No Translation Overhead: No need for translation (compilation or interpretation) since it's already in the CPU's native language.
oExample (Simplified):
o01100110 00001010 ; Binary sequence representing an addition operation
3.Summary:
oHigh-level languages provide abstraction, readability, and portability.
oMachine language is specific to the hardware, efficient, and executed directly by the CPU.
