Question 4

A network technician is configuring a device and needs to enter a MAC address. Which of the following is a valid MAC address in hexadecimal notation?

Accepted Answer

3A:4B:5C:6D:7E:8F. MAC addresses are 12 hexadecimal digits (0-9, A-F), typically displayed in pairs separated by colons, e.g., 3A:4B:5C:6D:7E:8F. Option A uses letters beyond F (G, H, I, J, K, L) which are not hex digits. Option B has only 6 digits (AB:CD:EF), which is too few. Option D uses Z, Y, W which are not valid hex digits. Only option C meets the requirements: 12 hex digits using only 0-9 and A-F.

Answer

1G:2H:3I:4J:5K:6L

Answer

AB:CD:EF

Answer

0X:1Z:2Y:3X:4W:5V

Answer

11.2 GB

Answer

5.8 GB

Answer

3.2 GB

Question 8

A technician is troubleshooting a computer that fails to boot. Which of the following types of firmware is responsible for initializing hardware and loading the operating system?

Answer

Operating system kernel

Answer

Boot loader

Answer

Device driver

Question 9

Which of the following best describes the function of a hypervisor?

Accepted Answer

It allows multiple operating systems to run on a single physical machine. A hypervisor allows multiple operating systems to run on one physical machine by virtualizing hardware. It does not manage cloud resources directly, nor is it an OS or antivirus.

Answer

It is a type of operating system designed for servers

Answer

It manages cloud resource allocation across multiple data centers

Answer

It provides antivirus protection for virtual machines
