What could cause a fixed disk error.
- A.
No-CD installed
- B.
Bad ram
- C.
Slow processor
- D.
Incorrect CMOS settings
Correct Answer
D. Incorrect CMOS settingsExplanation
Incorrect CMOS settings can cause a fixed disk error. The CMOS (Complementary Metal-Oxide-Semiconductor) settings store important information about the computer's hardware configuration. If these settings are not properly configured, it can lead to errors in accessing the fixed disk. This can include issues such as incorrect disk size, disk not being recognized, or problems with disk booting. Therefore, incorrect CMOS settings can be a potential cause for a fixed disk error.Rate this question:

Correct Answer
A. BusExplanation
The most common logical topologies are bus and ring. The bus topology is a network arrangement where all devices are connected to a single cable, known as the bus. Data is transmitted on the bus and received by all devices, but only the intended recipient processes it. This topology is simple and cost-effective, making it popular for small networks. The ring topology, on the other hand, connects devices in a circular loop, with each device connected to two neighboring devices. Data travels in one direction around the ring, passing through each device until it reaches its destination.Rate this question:

Correct Answer
C. Connection-orientedExplanation
TCP is a connection-oriented sub protocol because it establishes a reliable and ordered connection between two devices before transmitting data. This means that TCP ensures that all data packets are received in the correct order and without errors. It also provides flow control and congestion control mechanisms to manage the transmission of data. Unlike connectionless protocols, TCP requires a connection to be established before data transfer can occur, making it a connection-oriented protocol.Rate this question:

- C.
UDP
- D.
IP
Correct Answer
D. IPExplanation
The correct answer is IP. IP (Internet Protocol) is the sub protocol that enables TCP/IP to internetwork. It allows for the routing of data packets across multiple LAN segments and different types of networks through routers. TCP (Transmission Control Protocol) is responsible for establishing and maintaining a reliable connection between two devices, while ICMP (Internet Control Message Protocol) is used for error reporting and diagnostic functions. UDP (User Datagram Protocol) is a connectionless protocol that is used for sending datagrams without establishing a connection.

To eliminate the possibility of a broadcast storm, switches and bridges implement the ____.
- A.
RIP (Routing Information Protocol)
- B.
STP (Spanning Tree Protocol)
- C.
BGP (Border Gateway Protocol)
- D.
OSPF (Open Shortest Path First) protocol
Correct Answer
B. STP (Spanning Tree Protocol)Explanation
To eliminate the possibility of a broadcast storm, switches and bridges implement the Spanning Tree Protocol (STP). This protocol helps to prevent loops in a network by creating a loop-free logical topology. It achieves this by selectively blocking redundant paths and allowing only one active path between switches. By doing so, STP ensures that broadcast frames do not endlessly circulate in the network, preventing congestion and improving network efficiency. RIP, BGP, and OSPF are routing protocols used for different purposes and are not specifically designed to eliminate broadcast storms.Rate this question:

In IPv4 addressing, a node with an IP address of 168.34.88.29 belongs to a Class ____ network.
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
B. BExplanation
The IP address 168.34.88.29 belongs to a Class B network. In IPv4 addressing, the first octet of the IP address determines the class of the network. Class B networks have the first two octets reserved for the network portion, while the last two octets are used for host addressing. Therefore, based on the given IP address, it falls within the range of Class B networks.Rate this question:

The default subnet mask for a Class B network is ____.
- A.
255.0.0.0
- B.
255.255.0.0
- C.
255.255.255.0
- D.
255.255.255.255
Correct Answer
B. 255.255.0.0Explanation
The default subnet mask for a Class B network is 255.255.0.0. This subnet mask allows for a larger number of hosts compared to a Class C network, which has a default subnet mask of 255.255.255.0. The subnet mask 255.0.0.0 is not correct for a Class B network as it would allow for a much larger number of hosts than a Class B network can accommodate. The subnet mask 255.255.255.255 is a broadcast address and cannot be used as a subnet mask.Rate this question:

On an Ethenet network, a(n) ____ is the portion of a network in which collisions occur if two nodes transmit data at the same time.
- A.
Collision domain
- B.
Crash domain
- C.
Interference domain
- D.
Duplicate domain
Correct Answer
A. Collision domainExplanation
A collision domain is the portion of a network where collisions occur if two nodes transmit data at the same time. In an Ethernet network, all devices connected to a hub or a repeater are part of the same collision domain. When two devices transmit data simultaneously, a collision occurs, and both devices have to retransmit their data. This is because Ethernet uses a CSMA/CD (Carrier Sense Multiple Access with Collision Detection) protocol, which allows multiple devices to share the same network medium but requires collision detection and resolution. Therefore, the correct answer is collision domain.Rate this question:

C. RouterExplanation
A router is a multiport connectivity device that directs data between nodes on a network. Unlike switches and bridges, routers operate at the network layer of the OSI model, which allows them to make intelligent decisions about where to send data packets based on their destination IP addresses. Routers are commonly used in home and office networks to connect multiple devices and facilitate communication between them. They can also provide additional features such as network security and traffic management.Rate this question:

B. 32-bitExplanation
IPv4 addressing uses a 32-bit number to represent each IP address. This means that there are 2^32 (approximately 4.3 billion) unique IP addresses available in IPv4. Each IP address consists of four sets of 8-bit numbers separated by periods, such as 192.168.0.1. This 32-bit addressing scheme allows for the identification and communication of devices on a network, ensuring that each device has a unique identifier.Rate this question:
