What is APIPA related to ?
- A.
IP address
- B.
Multimedia
- C.
Software License
- D.
Programming
Correct Answer
A. IP addressExplanation
APIPA stands for Automatic Private IP Addressing. It is a feature in the Windows operating system that allows a computer to automatically assign itself a private IP address when it is unable to obtain an IP address from a DHCP server. This feature is useful in situations where a computer is connected to a network but cannot communicate with a DHCP server, such as when there is a network connectivity issue. Therefore, APIPA is related to IP addresses as it provides a way for devices to assign themselves an IP address in the absence of a DHCP server.Rate this question:

Correct Answer
E. Go to My Computer and confirm that the host drive is mapped, or the path exists in Network PlacesExplanation
The first action to take in this situation is to go to My Computer and confirm that the host drive is mapped, or the path exists in Network Places. This is important because if the drive is not mapped or the path does not exist, the shared network application will not be accessible. By checking this, you can determine if the issue lies with the mapping or path, and then take appropriate steps to resolve it.Rate this question:

To enable data and resource sharing between the LANs in the downtown office and the manufacturing plant in the suburbs, a router is needed. A router is a networking device that connects multiple networks together and routes data packets between them. It can analyze the destination IP address of each packet and determine the most efficient path for it to reach its destination. Therefore, a router is the most suitable device for connecting the two LANs and facilitating communication and data sharing between them.Rate this question:

Which physical connection is the fastest?
- A.
twisted pair
- B.
coaxial cable
- C.
fiber-optics
- D.
microwaves
Correct Answer
C. fiber-opticsExplanation
Fiber-optics is the fastest physical connection because it uses light to transmit data, allowing for extremely high speeds and large bandwidth. Unlike twisted pair and coaxial cable which use electrical signals, fiber-optics can transmit data over long distances without significant loss or interference. Microwaves, although they can transmit data wirelessly, are not as fast as fiber-optics in terms of data transmission speeds.Rate this question:

What can greatly reduce TCP/IP configuration problems?
- A.
WINS Server
- B.
WINS Proxy
- C.
DHCP Server
- D.
PDC
Correct Answer
C. DHCP ServerExplanation
A DHCP (Dynamic Host Configuration Protocol) server can greatly reduce TCP/IP configuration problems. DHCP automatically assigns IP addresses to devices on a network, eliminating the need for manual configuration. It also provides additional configuration settings such as subnet mask, default gateway, and DNS server addresses. By using a DHCP server, network administrators can ensure that devices are properly configured with the correct IP settings, reducing the chances of configuration errors and simplifying the management of TCP/IP configurations.Rate this question:

- A.
VPN
- B.
PPP
- C.
WEP
- D.
WPA

MAC
Correct Answer(s)
C. WEP
D. WPAExplanation
WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access) are both examples of wireless encryption. WEP was the original encryption protocol used for securing wireless networks, but it is now considered to be weak and easily compromised. WPA, on the other hand, is a more secure encryption protocol that was introduced as a replacement for WEP. It provides better security features and is recommended for protecting wireless networks. Both WEP and WPA are used to encrypt data transmitted over wireless networks to prevent unauthorized access and protect the privacy of the users.Rate this question:

80
- B.
443
- C.
