Which of the following technique is used to troubleshoot if the adapter card and its slots are working fine, but services are unavailable?
-
Replace adapter card that is electronically damaged
-
Visually inspect cards and cables and reconnect if necessary
-
Resolve hardware resource conficts
-
Replace adapter card that is physically damaged
Correct Answer
A. Visually inspect cards and cables and reconnect if necessaryExplanation
Visually inspecting cards and cables and reconnecting if necessary is the appropriate technique to troubleshoot if the adapter card and its slots are working fine but services are unavailable. This is because there may be loose connections or faulty cables causing the services to be unavailable, and by visually inspecting and reconnecting them, any issues can be identified and resolved.Rate this question:

Which of the following is not a function of fully uninterruptible Power Supply system?
-
Long term data backup
-
Keeping the batteries online
-
Monitor the power input line
-
Switch to output of battery power when a loss in power is detected
Correct Answer
A. Long term data backupExplanation
A fully uninterruptible Power Supply (UPS) system is designed to provide continuous power to critical devices in the event of a power outage. It ensures that the devices connected to it remain operational without any interruption. The functions of a UPS system include keeping the batteries online, monitoring the power input line, and switching to the output of battery power when a loss in power is detected. However, long term data backup is not a function of a UPS system. Backup of data is typically handled by separate data storage systems or backup solutions.Rate this question:

Salman need to attache an external CD-Rom drive. Which option needs to be verified when installing an external drive that in not checked normally on installing a internal drive on a notebook?
-
Close the screen of the notebook PC
-
Verify that the power switch, or power supply, is turned off.
-
Verify that proper device drives are installed.
-
Verify that Hard drive is disconnected
Correct Answer
A. Verify that the power switch, or power supply, is turned off.Explanation
When installing an external CD-Rom drive on a notebook, it is important to verify that the power switch or power supply is turned off. This is not normally checked when installing an internal drive on a notebook because the internal drive is already connected to the power supply. However, when attaching an external drive, it is necessary to ensure that the power switch or power supply is turned off to avoid any potential damage or electrical shock.Rate this question:

-
Class 5
-
Class 3
-
Class 1
-
Class 2
-
Class 4
Correct Answer
A. Class 2Explanation
Class 2 lasers are considered safe for eye exposure because they emit low power levels that are not likely to cause damage, even with chronic and continuous exposure. Class 1 lasers are also safe, but they are limited to very low power levels. Class 3 lasers can cause eye damage with direct exposure, while Class 4 lasers can cause eye damage and also pose a fire hazard. The statement in the question suggests that barcode readers, which are commonly used in various industries, fall under the Class 2 category.Rate this question:

Port COM1 is type of---------------------------------------.
-
Parallel Port
-
PS/2 Port
-
USB port
-
Serial Port
Correct Answer
A. Serial PortExplanation
The correct answer is Serial Port. A serial port is a type of port that enables serial communication, which means data is transferred one bit at a time. It is commonly used to connect devices such as modems, mice, and printers to a computer. Unlike parallel ports, which transfer multiple bits simultaneously, a serial port transfers data sequentially. PS/2 ports are used for connecting keyboards and mice, USB ports are used for connecting various devices, and parallel ports are used for connecting printers and other parallel devices.Rate this question:

Sushil is planning to create a data processing-intensive crossword generator software. He had recently purched a good quality processor with L1 and L2 caches but want to increase its speed to allow his software to be tested well. Which of the following methods can he use to increase the speed of his processor at minimal cost?
-
Purchase another processor with L3 cache also.
-
Buy a new processor that supports MMX
-
Use Throttling
-
Use overclocking
Correct Answer
A. Use overclockingExplanation
Overclocking is a method that Sushil can use to increase the speed of his processor at minimal cost. Overclocking involves increasing the clock speed of the processor beyond its default specifications, which can result in improved performance. This can be done by adjusting the settings in the computer's BIOS or using specialized software. By overclocking his processor, Sushil can achieve a higher processing speed without having to purchase additional hardware or software.Rate this question:

-
The PC Card slot has been disabled in the CMOS
-
The card may be faulty
-
Th edevice is physically not present
-
The PC controller in the PC may be faulty
Correct Answer
A. The PC Card slot has been disabled in the CMOSExplanation

The other options listed are all possible conditions that can cause this problem, except for "The PC Card slot has been disabled in the CMOS." If the PC Card slot is disabled in the CMOS (Complementary Metal-Oxide-Semiconductor), it means that the system's BIOS settings have been configured to disable the slot, which is not related to the adapter showing an exclamation mark on a yellow background.Rate this question:

For a node on a network following information are given: IP Address is equal to 139.87.140.76 Subnet mask is equal to 255.255.255.0 Which is the correct network ID for this system?
-
139.87.255.255
-
255.255.255.76
-
139.87.140.0
-
139.87.140.255
Correct Answer
A. 139.87.140.0Explanation
The correct network ID for this system is 139.87.140.0 because the subnet mask is 255.255.255.0, which means that the first three octets of the IP address are the network address and the last octet can be any value within the network. Therefore, the network ID is obtained by setting the last octet to 0.Rate this question:

Which of the following statement is NOT TRUE about software based firewall security issues?
-
Browser used for the communication is firewall security issue in software based firewall as some browser bypass software base firewall
-
Disabling is firewall security issue, because it isn’t integrated into a hardware device it can be disabling by mistake
-
Open ports is firewall security issue, As it’s sometimes difficult to configure FTP or other internetwork communication through a firewall
-
Outgoing traffic is a firewall security issue because firewall controls only incoming traffic
Correct Answer
A. Browser used for the communication is firewall security issue in software based firewall as some browser bypass software base firewallExplanation
The statement "Browser used for the communication is firewall security issue in software based firewall as some browser bypass software base firewall" is not true because software-based firewalls are designed to control and monitor the traffic that passes through the browser as well. They are capable of filtering and blocking unwanted or malicious traffic, including traffic from browsers. Therefore, the statement is incorrect as it suggests that browsers can bypass the firewall, which is not the case.Rate this question:
