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). STP is a network protocol that prevents loops in a network topology by creating a loop-free logical topology. It achieves this by selectively blocking redundant paths and allowing only one active path between any two network devices. By doing so, STP ensures that broadcast frames and other network traffic do not endlessly circulate in the network, thereby preventing a broadcast storm.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
A node with an IP address of 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 a range of IP addresses from 128.0.0.0 to 191.255.255.255, and the first octet falls within this range.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. Class B networks have a default subnet mask of 255.255.0.0 because they have a network portion of 16 bits and a host portion of 16 bits. This allows for a maximum of 65,534 hosts on each network.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 other words, it is the area where packets from different devices can collide and cause data loss or corruption. This can happen in Ethernet networks when multiple devices are connected to a shared medium, such as a hub or a half-duplex switch. In a collision domain, devices must follow the CSMA/CD (Carrier Sense Multiple Access with Collision Detection) protocol to avoid collisions by checking for activity on the network before transmitting data.Rate this question:

A ____ is a multiport connectivity device that directs data between nodes on a network
- A.
Switch
- B.
Bridge
- C.
Router
- D.
Gateway
Correct Answer
C. RouterExplanation
A router is a multiport connectivity device that directs data between nodes on a network. Unlike switches and bridges, routers are designed to connect multiple networks together and determine the best path for data to travel. Routers use routing tables to make decisions about where to send data packets based on their destination IP addresses. Gateways, on the other hand, are devices that connect different types of networks together, such as a local area network (LAN) to the internet. Therefore, a router is the correct answer as it specifically directs data between nodes on a network.Rate this question:

In IPv4 addressing, each IP address is a unique ____ number
- A.
12-bit
- B.
32-bit
- C.
64-bit
- D.
128-bit
Correct Answer
B. 32-bitExplanation
In IPv4 addressing, each IP address is a unique 32-bit number. This means that IPv4 addresses are composed of 32 binary digits or bits, which are divided into four groups of eight bits each, known as octets. Each octet is represented in decimal form, ranging from 0 to 255, and is separated by periods. This addressing scheme allows for approximately 4.3 billion unique IP addresses to be assigned.Rate this question:
