WGU Introduction to IT Introduction-to-IT Prüfungsfragen mit Lösungen (Q10-Q15):

10. Frage
Which securely best practice designates specific persons who are authorized to view and edit particular parts of a database system?

Antwort: B

Begründung:
*Role-based access control (RBAC) is a securely best practice that designates specific persons who are authorized to view and edit particular parts of a database system.
*In RBAC, access permissions are assigned based on predefined roles or job functions within an organization.
*Here's how RBAC works:
1.Roles: Define roles based on job responsibilities (e.g., administrator, manager, user).
2.Permissions: Assign specific permissions (read, write, execute) to each role.
3.Users: Associate users with roles.
4.Access Control: Users inherit permissions from their assigned roles.
*Benefits of RBAC:
oGranularity: Allows fine-grained control over access rights.
oScalability: Easily manage access for large user bases.
oSecurity: Reduces the risk of unauthorized access.
*Example: An employee in the HR department might have read-only access to employee records, while an administrator has full editing rights.
*RBAC ensures that only authorized individuals can access specific data or perform certain actions within the database system.

11. Frage
How does application software differ from operating systems?
Choose 2 answers

Antwort: A,D

Begründung:
Application software and operating systems serve different purposes within a computer system. The primary distinction lies in their functionality and interaction with the computer's hardware and the user.
*Operating Systems (OS):
oAn OS is system software that acts as an intermediary between the user and the computer hardware.
oIt manages and coordinates the hardware components of a computer system, including the CPU, memory, storage devices, and peripheral devices.
oThe OS provides a platform for application software to run and facilitates user interaction with the system through a user interface.
oExamples include Microsoft Windows, Linux, and macOS.
*Application Software:
oApplication software consists of programs designed to perform specific tasks for the user.
oThese tasks can range from productivity applications like word processors and spreadsheets (Answer A) to communication tools like email clients (Answer B).
oUnlike the OS, application software does not manage hardware resources directly. Instead, it relies on the OS to provide these services.
oExamples include Microsoft Word, Excel, and Mozilla Firefox.
*Key Differences:
oApplication software is run by the end-user to perform specific tasks, while the OS runs in the background, managing the overall operation of the computer system.
oThe OS directly supports and manages the computer hardware system, which is not the case for application software.

12. Frage
What is the primary role of the database administrator?

Antwort: C

Begründung:
The core responsibility of a database administrator (DBA) centers around managing and optimizing Database Management Systems (DBMS). This includes:
*Installation and Configuration: Setting up new database instances, applying relevant configurations, and ensuring they align with the organization's needs.
*Maintenance: Performing regular backups, security updates, and patch management to keep the databases secure and healthy.
*Performance Analysis: Monitoring database performance, identifying bottlenecks, and implementing optimizations to ensure efficient data retrieval and operations.
*Troubleshooting: Proactively addressing database errors, resolving operational issues, and ensuring data integrity.


13. Frage
How does high-level programming language differ from low-level language?

Antwort: B


14. Frage
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?

Antwort: B

Begründung:
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.
