What does an assigned IP addres 169.254.0.12 indicate?
Correct Answer
D. The computer is configured for DHCP and cannot connect to the DHCP server.
Explanation
An IP address of 169.254.0.12 is in the range of Automatic Private IP Addressing (APIPA). APIPA is a feature in DHCP that assigns a unique IP address to a computer when it cannot obtain an IP address from a DHCP server. Therefore, the computer is configured for DHCP but is unable to connect to the DHCP server, resulting in the assignment of the APIPA address.
3.
Which method of communication is used to support Ethernet type networks?
Correct Answer
B. Broadcast
Explanation
Broadcast is the correct answer because it is a method of communication used to support Ethernet type networks. In a broadcast communication, a message is sent from one device to all devices on the network, allowing for efficient and simultaneous communication between multiple devices. This method is commonly used in Ethernet networks to transmit data packets to all connected devices, ensuring that all devices receive the information.

Which wireless standard is designed for a maximum data tranfer rate of 11 Mb?
Correct Answer
B. IEEE 802.11b
Explanation
IEEE 802.11b is the correct answer because it is a wireless standard specifically designed for a maximum data transfer rate of 11 Mbps. This standard operates in the 2.4 GHz frequency range and uses direct-sequence spread spectrum (DSSS) modulation to transmit data. It was introduced as an improvement over the original IEEE 802.11 standard, offering faster speeds and better compatibility with existing equipment. While other wireless standards such as IEEE 802.11a and IEEE 802.11g provide higher data transfer rates, IEEE 802.11b is specifically designed for 11 Mbps. Bluetooth and IEEE 802.6 are not wireless standards designed for this data transfer rate.
5.
Which two are examples of wireless encryption? (Select two answers.)
Correct Answer(s)
C. WEP
D. WPA
Explanation
WEP and WPA are examples of wireless encryption. WEP (Wired Equivalent Privacy) is an older encryption protocol that was commonly used to secure wireless networks. However, it is now considered weak and easily crackable. WPA (Wi-Fi Protected Access) is a more secure encryption protocol that was introduced as an improvement over WEP. It provides stronger encryption and better security features to protect wireless networks from unauthorized access. Both WEP and WPA are used to ensure the confidentiality and integrity of data transmitted over wireless networks.
6.
Which item is an example of a physical network address?
Correct Answer
B. MAC address
Explanation
A physical network address refers to a unique identifier assigned to a network interface card (NIC) in a device. The MAC address, also known as the Media Access Control address, is a hardware address that is assigned to the NIC by the manufacturer. It is a 48-bit address and is used for communication within a local area network (LAN). Unlike IP addresses, which can change or be assigned dynamically, MAC addresses are permanent and cannot be changed. Therefore, the MAC address is an example of a physical network address.
7.
Which are the default settings for a Windows XP computer network adapter?
Correct Answer
A. DHCP and configured as part of a workgroup.
Explanation
The default settings for a Windows XP computer network adapter are DHCP and configured as part of a workgroup. DHCP stands for Dynamic Host Configuration Protocol, which allows the computer to automatically obtain an IP address from a DHCP server. Configuring the network adapter as part of a workgroup means that the computer is not joined to a domain, but rather connected to a local network of computers. This setting is commonly used for home or small office networks where there is no centralized server for user authentication and management.
8.
What does the term "Map Network Drive" mean?
Correct Answer
B. Create a shortcut to a network location.
Explanation
The term "Map Network Drive" refers to creating a shortcut to a network location. This allows the user to easily access and navigate to a specific folder or shared resource on a network. By mapping a network drive, the user can assign a drive letter to the network location, making it appear as if it is a local drive on their computer. This simplifies the process of accessing files and resources stored on a network, as they can be accessed directly from the mapped drive without having to manually navigate through the network.
9.
Which is the best example of a secure password?
Correct Answer
B. MySpecialPa$$w0rd
Explanation
The best example of a secure password is "MySpecialPa$$w0rd" because it includes a combination of uppercase and lowercase letters, numbers, and special characters. This makes it more difficult for hackers to guess or crack the password. It also has a sufficient length, which adds an extra layer of security.
10.
What icon is used to identify a shared folder?
Correct Answer
A. An open hand palm up.
Explanation
The open hand palm up icon is used to identify a shared folder. This icon represents the concept of sharing and indicates that the folder is accessible to others. It is a universally recognized symbol for sharing and is commonly used in various operating systems and applications to denote shared folders.
11.
Which is used to provide a centralized authentication method from remote locations?
Correct Answer
E. DHCP
Explanation
DHCP (Dynamic Host Configuration Protocol) is used to provide a centralized authentication method from remote locations. It automatically assigns IP addresses to devices on a network, allowing them to connect and communicate. By centrally managing and distributing IP addresses, DHCP simplifies network administration and provides a secure and efficient authentication method for remote locations.
12.
What is the purpose of a DNS server?
Correct Answer
B. To resolve domain names to IP addresses.
Explanation
A DNS server is responsible for translating domain names, which are user-friendly and easy to remember, into IP addresses, which are numerical and necessary for devices to communicate with each other on the internet. This translation process allows users to access websites and other online resources by simply typing in a domain name, without having to remember the corresponding IP address. Therefore, the purpose of a DNS server is to resolve domain names to IP addresses.

What is another name for a computer to computer network?
Correct Answer
D. Ad hoc
Explanation
Ad hoc is another name for a computer to computer network. This term refers to a temporary or impromptu network that is created on-the-fly without the need for pre-existing infrastructure or centralized control. In an ad hoc network, devices connect directly with each other, forming a decentralized network without relying on a dedicated server.
