Which of the following IP addresses would a technician see if acomputer is connected to a multifunction network device and isattempting to obtain an IP address automatically but is notreceiving an IP address from the DHCP server?
- A.
172.16.10.10
- B.
192.168.0.10
- C.
169.254.10.10
- D.
192.168.10.10
Correct Answer
C. 169.254.10.10Explanation
If a computer is connected to a multifunction network device and is attempting to obtain an IP address automatically but is not receiving one from the DHCP server, it will most likely receive an IP address in the range of 169.254.0.0 to 169.254.255.255. This range is reserved for Automatic Private IP Addressing (APIPA), which is used when a device is unable to obtain an IP address from a DHCP server. The IP address 169.254.10.10 falls within this range and would be the IP address that the technician would see in this scenario.Rate this question:

What is the total number of devices that can be daisy-chained toan IEEE 1394 port?
- A.
127
- B.
63
- C.
15
- D.
255
Correct Answer
B. 63Explanation
The correct answer is 63. The IEEE 1394 port, also known as FireWire, allows for daisy-chaining devices. Each device in the chain requires a unique identifier, known as a node ID. In the case of IEEE 1394, the node ID is a 6-bit value, allowing for a total of 63 unique IDs (2^6 - 1). Therefore, the maximum number of devices that can be daisy-chained to an IEEE 1394 port is 63.Rate this question:

How should you apply spray cleaner to a monitor?
- A.
Spray the cleaner directly on the monitor screen.
- B.
Spray the cleaner on the top of the monitor and wipe down
- C.
Spray evenly on the monitor.
- D.
Spray the cleaner on a clean, lint-free cloth first.
Correct Answer
D. Spray the cleaner on a clean, lint-free cloth first.Explanation
When applying spray cleaner to a monitor, it is important to avoid spraying the cleaner directly on the screen. This can cause the cleaner to seep into the monitor and potentially damage the internal components. Instead, it is recommended to spray the cleaner onto a clean, lint-free cloth first. This allows you to control the amount of cleaner applied and ensures that it is evenly distributed across the screen when wiping it down.Rate this question:

Moving your CPU’s speed beyond its normal operating range iscalled _____________.
- A.
Overclocking
- B.
Overdriving
- C.
Overpowering
- D.
Overspeeding
Correct Answer
A. OverclockingExplanation
Overclocking refers to the process of increasing the clock speed of a computer's central processing unit (CPU) beyond its normal operating range. This is typically done to achieve higher performance and faster processing speeds. By increasing the clock speed, the CPU can perform more calculations per second, resulting in improved overall system performance. However, overclocking can also lead to increased heat generation and potential instability if not done correctly or if the hardware is not capable of handling the higher speeds.Rate this question:

What is the main advantage of selecting a 64-bit operating systemover a 32-bit operating system?
- A.
The ability to use software-based data execution prevention (DEP)
- B.
The ability to use unsigned drivers
- C.
The ability to access more than 4 GB of RAM
- D.
The ability to run multiple 16-bit programs in separate memory spaces
Correct Answer
C. The ability to access more than 4 GB of RAMExplanation
The main advantage of selecting a 64-bit operating system over a 32-bit operating system is the ability to access more than 4 GB of RAM. A 32-bit operating system can only support up to 4 GB of RAM, while a 64-bit operating system can support much larger amounts of RAM, allowing for better performance and the ability to run memory-intensive applications. This is particularly beneficial for users who require a large amount of memory for tasks such as video editing, gaming, or running virtual machines.Rate this question:

Why would the display on a laptop get dimmer when the powersupply from the AC outlet is disconnected?
- A.
The laptop cannot use full brightness when on battery power.
- B.
Power management settings on the laptop.
- C.
To operate properly, laptop displays require an alternating current power source.
- D.
Security settings on the laptop.
Correct Answer
B. Power management settings on the laptop.Explanation
When the power supply from the AC outlet is disconnected, the laptop switches to battery power. In order to conserve battery life, power management settings on the laptop may automatically adjust the display brightness to a lower level. This helps to reduce power consumption and extend the battery runtime. Therefore, the display on a laptop may get dimmer when disconnected from the AC outlet due to the power management settings.Rate this question:

Which type of RAM has a peak transfer of 12,800 MB/s?
- A.
DDR3-800
- B.
DDR2-1600
- C.
DDR3-1600
- D.
DDR2-800
Correct Answer
C. DDR3-1600Explanation
DDR3-1600 RAM has a peak transfer of 12,800 MB/s. DDR3 refers to the third generation of DDR (Double Data Rate) RAM, which is faster and more efficient than its predecessors. The number 1600 indicates the data transfer rate in megahertz (MHz), meaning that this type of RAM can transfer data at a rate of 1600 million cycles per second. Since each cycle transfers two pieces of data, the effective data transfer rate is 1600 MHz x 2 = 3200 MHz. To convert this to megabytes per second (MB/s), we multiply by 8 (since there are 8 bits in a byte), resulting in a peak transfer rate of 12,800 MB/s.Rate this question:

When it comes to computer case form factors, which of thefollowing provides the most room for effective cooling?
- A.
ATX
- B.
BTX
- C.
ITX
- D.
MicroATX
Correct Answer
B. BTXExplanation
BTX provides the most room for effective cooling compared to the other form factors mentioned. BTX (Balanced Technology Extended) is a form factor designed to improve airflow and cooling efficiency by rearranging the components and positioning the CPU near the front of the case. This allows for better heat dissipation and reduces hot spots within the case. ATX, ITX, and microATX form factors do not prioritize cooling as much as BTX does, making BTX the correct answer.Rate this question:

Which device limits network broadcasts, segments IP addressranges, and interconnects different physical media?
- A.
Switch
- B.
WAP
- C.
Firewall
- D.
Router
Correct Answer
D. RouterExplanation
A router is a device that limits network broadcasts, segments IP address ranges, and interconnects different physical media. It is responsible for directing network traffic between different networks or subnets, ensuring that data packets are delivered to their intended destinations efficiently. Routers use routing tables to determine the best path for forwarding data packets based on IP addresses. Unlike switches, routers operate at the network layer of the OSI model and can connect networks using different protocols and media types. Therefore, a router is the correct answer for this question.Rate this question:

Which of the following power connections might be used by harddrives? (Select the two best answers.)
- A.
8-pin
- B.
7-pin

Molex
- D.
15-pin
- E.
Berg
Correct Answer(s)
A. 8-pin
C. Molex
D. 15-pinExplanation
Hard drives typically use two types of power connections: Molex and 15-pin SATA power connectors. The Molex connector is a standard power connector that has been used for many years in computer systems. The 15-pin SATA power connector is a newer type of power connector that is specifically designed for SATA devices, including hard drives. The 8-pin and 7-pin connectors mentioned in the options are not commonly used for hard drives, making them incorrect answers. The Berg connector is also not typically used for hard drives, making it an incorrect answer as well.Rate this question:
