A technician installed a network adapter in a computer and wants to test network connectivity. The ping command can only receive a response from local workstations. What could be causing the problem?
-
The NIC driver is out of date.
-
The operating system is not compatible with the remote sites.
-
The TCP/IP protocol stack is not loaded.
-
The default gateway is not set.
Correct Answer
A. The default gateway is not set.Explanation
The default gateway is not set. In order to communicate with devices outside of the local network, a default gateway needs to be configured on the computer. The default gateway is the IP address of the router or gateway device that connects the local network to other networks. Without a default gateway, the computer does not know where to send network traffic that is destined for remote sites. Therefore, the ping command can only receive responses from local workstations because it can only communicate within the local network.Rate this question:

Why does the cable from the power supply to the motherboard have different colored wires?
-
A single wire could not carry enough current.
-
There is one wire for each motherboard component.
-
Each wire carries a different voltage.
-
The motherboard slot requires the number of wires that are represented by the different colors.
Correct Answer
A. Each wire carries a different voltage.Explanation
The cable from the power supply to the motherboard has different colored wires because each wire carries a different voltage. This is necessary because different components on the motherboard require different levels of voltage to function properly. By using different colored wires, it becomes easier to identify and connect the wires to the correct voltage pins on the motherboard, ensuring that each component receives the appropriate voltage it needs to operate effectively.Rate this question:

A user is reporting that a new external hard drive is defective. The laptop will allow access to the drive at times, and then will report that the drive cannot be found. Upon an initial examination of the laptop, it is discovered that the user has ten USB devices connected to the laptop. What is the best quick solution to this problem?
-
Remove all the peripherals except the hard drive and observe the results
-
Move the laptop to another location and observe the results.
-
Replace the power adapter and observe the results.
-
Replace the USB hub and observe the results.
-
Flash the BIOS on the laptop and observe the results.
Correct Answer
A. Remove all the peripherals except the hard drive and observe the resultsExplanation
The best quick solution to this problem is to remove all the peripherals except the hard drive and observe the results. This is because having too many USB devices connected to the laptop can cause power and resource issues, leading to intermittent access to the external hard drive. By removing the peripherals, the laptop can allocate sufficient power and resources to the hard drive, potentially resolving the issue of it not being found.Rate this question:

A technician is asked to wire a network that supports CSMA/CD. Which architecture and physical topology should the technician use for supporting this access control method?
-
Ethernet and Star
-
FDDI and Ring
-
Token Ring and Double Ring
-
Wireless and Ring
Correct Answer
A. Ethernet and StarExplanation
CSMA/CD (Carrier Sense Multiple Access/Collision Detection) is an access control method used in Ethernet networks. In this method, devices on the network listen for carrier signals before transmitting data and if a collision occurs, the devices involved in the collision detect it and take appropriate actions. Therefore, the technician should use the Ethernet architecture and a star physical topology. In a star topology, all devices are connected to a central hub or switch, allowing for easy detection of collisions and efficient communication.Rate this question:

When installing a service pack or security patches on an operating system, what should be done to protect the system in the event of a faulty or aborted installation?
-
Create a restore point.
-
Check the updates for the latest ones.
-
Disable Automatic Updates to prevent interference with the current operation.
-
Test all aspects to ensure that the update is correct for the operating system.
Correct Answer
A. Create a restore point.Explanation
When installing a service pack or security patches on an operating system, it is important to create a restore point to protect the system in the event of a faulty or aborted installation. A restore point allows the system to be rolled back to a previous state before the installation, effectively undoing any changes made during the installation process. This ensures that if something goes wrong or the installation is not successful, the system can be restored to its previous working condition without any major consequences.Rate this question:

A network administrator has finished migrating from a peer-to-peer network to a new client-server network configuration. What are two advantages of the new configuration? (Choose two.)
-
The total cost of the new solution is considerably lower.
-
Data is more secure in the event of hardware failures.
-
Individual users are in control of their own computers and network resources
-
Data resources and access are centrally controlled.
-
Personnel costs are lower because a dedicated network administrator is no longer necessary.
Correct Answer(s)
A. Data is more secure in the event of hardware failures.
A. Data resources and access are centrally controlled.Explanation
The new client-server network configuration provides two advantages. Firstly, data is more secure in the event of hardware failures. This is because the data is stored centrally on servers, which are typically equipped with redundancy measures such as RAID and backup systems. Secondly, data resources and access are centrally controlled. This means that the network administrator has the ability to manage and control user access to data and resources, ensuring better security and efficient allocation of resources.Rate this question:

A customer needs to purchase a new power supply for a computer. What must be considered when selecting an appropriate power supply?
-
The power supply converts DC to AC.
-
The power supply has sufficient wattage to support all components inside the computer.
-
The power supply provides at least 800 V.
-
The power supply must have both a P-8 and P-9 connector.
Correct Answer
A. The power supply has sufficient wattage to support all components inside the computer.Explanation
The most important consideration when selecting an appropriate power supply for a computer is to ensure that it has sufficient wattage to support all components inside the computer. This is because different components in a computer require different amounts of power, and if the power supply does not have enough wattage, it may not be able to provide enough power to all the components, leading to system instability or failure. Therefore, it is crucial to choose a power supply with sufficient wattage to meet the power demands of the computer.Rate this question:
