NEW QUESTION # 112
Which item information should be stored in a database to determine a student's previous academic year's course load?
Answer: C
Explanation:
To determine a student's previous academic year's course load, the most crucial piece of information is the course identification number. This unique identifier allows for the retrieval of specific data related to each course, such as the number of credit hours or units associated with the course, which directly contributes to the calculation of the course load.
Here's a step-by-step explanation of how this information is used:
1.Identify the Student: The database must have a record of the student for whom the course load is being determined.
2.Retrieve Course Records: Using the student's identification, the database retrieves all course records associated with that student for the specified academic year.
3.Use Course Identification Numbers: Each course taken by the student will have a unique course identification number.
4.Determine Credit Hours: The course identification number can be used to look up the credit hours or units for each course, as this information is typically tied to the course ID in the database.
5.Calculate Course Load: By summing the credit hours for all courses taken in the previous academic year, the student's course load can be calculated.
References: The process of determining course load and its impact on student performance is discussed in academic literature, which emphasizes the importance of course identification numbers in tracking academic progress1234.
NEW QUESTION # 113
What is an important strategy of business continuity planning?
Answer: D
Explanation:
Data mirroring is an important business continuity strategy because it maintains a synchronized copy of data on a separate storage system or site. In Information Technology, mirroring supports rapid recovery by ensuring that if the primary data store fails, an up-to-date replica is available to restore operations. Mirroring may be implemented through storage replication, database replication, or real-time backup technologies, and it is often used for high-availability systems that require minimal data loss. This approach directly supports business continuity goals by reducing recovery time and limiting the recovery point, meaning less data is lost between the failure and the restored system. User authentication and data encryption are critical security controls, but they do not by themselves ensure operational continuity after outages or disasters. Service variety is not a standard continuity strategy term in most IT curricula. Business continuity focuses on redundancy, replication, failover, and recovery processes. Since mirroring creates a continuously updated duplicate of critical data, it is a core strategy used to maintain availability and speed restoration. Therefore, the correct answer is data mirroring.
NEW QUESTION # 114
Which part of a computer system is hardware?
Answer: C
Explanation:
Hardware refers to the physical, tangible components of a computer system, while software refers to programs and instructions. Random-access memory, or RAM, is hardware because it is a physical set of memory chips installed in the computer, typically on removable modules. RAM provides temporary working storage for the operating system and applications while they are running, allowing fast read and write access compared to long-term storage devices. A compiler is software that translates source code into machine code. The kernel is software and is the core part of an operating system that manages resources such as processes, memory, and device access. The operating system itself is also software that controls the computer and provides services to applications. In Information Technology fundamentals, distinguishing hardware from software is a key concept: hardware includes CPU, RAM, motherboard, storage, and peripherals; software includes the operating system, applications, and programming tools. Since RAM is a physical component, it is the correct answer for the hardware part listed.
NEW QUESTION # 115
Why is business continuity planning essential?
Answer: D
Explanation:
Business continuity planning (BCP) is essential for several reasons:
1.Minimizing Downtime:
oBCP ensures that an organization can continue its critical functions during and after disruptions.
oBy having a well-thought-out plan, companies can minimize downtime and quickly resume operations.

oIt goes beyond traditional business plans, focusing on resilience during adversity.
3.Economic Stability:
oEconomic downturns (e.g., recessions) pose significant threats to businesses.
oA continuity plan helps companies sustain operations even during tough times, preventing financial instability.
4.Adaptability to Growth:
oDuring periods of growth, businesses need to scale rapidly.
oA continuity plan ensures that infrastructure, resources, and workforce can adapt effectively.
