When a pc first connects to the network, it attempts to lease an address from what server?(hint: dealing with dynamically assigned IP addresses)
-
APIPA server
-
DHCP server
-
MIDI server
-
AIPPA server
Correct Answer
A. DHCP serverExplanation
When a PC first connects to a network, it needs an IP address to communicate with other devices. The DHCP (Dynamic Host Configuration Protocol) server is responsible for assigning and managing IP addresses dynamically. It leases an IP address to the PC for a specific period of time, allowing it to join the network. The APIPA (Automatic Private IP Addressing) server is not involved in this process, as it assigns a default IP address when a DHCP server is not available. The MIDI server is unrelated to IP address assignment, and the AIPPA server does not exist.Rate this question:

A customer calls your shop and is angry about a product they purchased from there yesterday. How should you handle this situation?
-
Hang up on the customer
-
Tell the customer that there is nothing you can do for them.
-
Listen to the customers complaint and attempt to help them.
-
Immediately get your supervisor.
Correct Answer
A. Listen to the customers complaint and attempt to help them.Explanation
In a situation where a customer is angry about a product they purchased, it is important to handle the situation professionally and empathetically. Hanging up on the customer or telling them that there is nothing you can do for them would only escalate the situation further and damage the customer relationship. Therefore, the best approach is to listen attentively to the customer's complaint, showing understanding and empathy, and then attempt to find a solution or offer assistance in resolving their issue. In more complex cases, involving a supervisor may be necessary, but the initial step should always be to actively listen and try to help the customer.Rate this question:

Which of the following protocols guarantees packet delivery?
-
TCP
-
UPS
-
IP
-
UDP
Correct Answer
A. TCPExplanation
TCP (Transmission Control Protocol) guarantees packet delivery by using a reliable and connection-oriented approach. It ensures that all packets are successfully delivered to the destination by implementing mechanisms like acknowledgments, retransmissions, and flow control. TCP establishes a reliable and error-free communication channel between the sender and receiver, making it suitable for applications that require guaranteed delivery of data, such as web browsing, file transfer, and email. On the other hand, UDP (User Datagram Protocol) does not guarantee packet delivery as it is connectionless and does not have mechanisms for error recovery or flow control.Rate this question:

Cmos settings
-
Power supply
-
None of the above
Correct Answer
A. Power supplyExplanation
When replacing a damaged motherboard with a good one, it is important to first test the power supply. This is because a faulty power supply can cause damage to the motherboard or other components. By testing the power supply, you can ensure that it is functioning properly and providing the correct amount of power to the motherboard. Testing the BIOS or CMOS settings would not be necessary in this situation, as they are specific to the motherboard and not likely to be affected by the replacement. Therefore, the correct answer is power supply.Rate this question:

To limit how much disk space a user account can access, an administrator can set which of the following?
-
User profiles
-
Group profiles
-
User access levels
-

Correct Answer
A. Disk quotasExplanation
An administrator can set disk quotas to limit how much disk space a user account can access. Disk quotas allow administrators to allocate a specific amount of disk space to each user, preventing them from exceeding the allocated limit. This helps in managing disk space usage and ensuring fair distribution of resources among users. By implementing disk quotas, administrators can prevent individual users from monopolizing the available disk space and ensure efficient utilization of storage resources.Rate this question:

An extended partition refers to a type of partition on a hard drive that can be divided into multiple logical drives. Unlike a primary partition, which can only contain one logical drive, an extended partition allows for the creation of multiple logical drives, such as D and E. This allows for better organization and allocation of storage space on the hard drive.Rate this question:
