WGU Introduction to IT Sample Questions (Q43-Q48):

NEW QUESTION # 43
What does a modem do?

Answer: D

Explanation:
A modem serves as the connection between the customer network and the internet service provider. In Information Technology networking, modem stands for modulator-demodulator. Traditionally, it converts outgoing digital data from a computer or router into a form suitable for transmission over the provider's communication medium and converts incoming signals back into digital data. Depending on the service type, this may involve cable, DSL, fiber, or cellular technologies, each using specific signaling methods. The modem typically terminates the ISP line and hands off connectivity to a router or directly to a computer.
Option A describes routing or switching behavior rather than a modem function. Option B describes a server that offers hosted services. Option D describes a firewall, which protects a trusted network by filtering traffic from untrusted networks. Since the essential purpose of a modem is enabling communication between the customer premises equipment and the ISP network, the correct choice is that it serves as the connection between the customer network and the internet service provider. Therefore, the correct answer is option C.

NEW QUESTION # 45
Which motherboard component is used for short-term storage of data?

Answer: A

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 # 46
Which securely best practice designates specific persons who are authorized to view and edit particular parts of a database system?

Answer: A

Explanation:
*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.
