1. Which is true of a star topology

Correct Answer: Correct answer is: (A) If 1 cable breaks then that device fails but the rest of the network still runs.

Exam Relevance: CCNA, Network+ Certification, CompTIA A+

Difficulty: Easy

Concept notes: In a star topology, each device is connected to a central hub or switch. If a cable connecting a single device to the hub breaks, only that device is affected, while the rest of the network continues to function.

Common Mistakes: A common misunderstanding is that a failure in one cable will affect the entire network, similar to a bus topology. However, in a star topology, the failure is isolated to the specific device.

Explanations: In a star topology, each device is connected to a central hub or switch. If a cable connecting a single device to the hub breaks, only that device is affected, while the rest of the network continues to function. This is because the central hub maintains connections to all other devices, ensuring that the network remains operational.

Option Analysis:

Option A: Correct. In a star topology, if one cable breaks, only the device connected to that cable fails, while the rest of the network continues to function.
Option B: Incorrect. In a star topology, a single cable failure does not cause the entire network to fail.
Option C: Incorrect. While the rest of the network continues to function, the device connected to the broken cable will fail.
Option D: Incorrect. Data rerouting is not a feature of a star topology; the network simply continues to function without the failed device.

Mnemonic: Star fails one, not all.

2. What's a mesh network?

Correct Answer: Correct answer is: (B) Every computer connected to every computer.

9. What is the name of network topology in which there are bi-directonal links between each possible node?

Correct Answer: Correct answer is: (B) Mesh topology.

Exam Relevance: CCNA, Network+ Certification, CompTIA Network+

Difficulty: Moderate

Concept notes: In a mesh topology, each node is connected to every other node with bi-directional links, allowing for multiple paths between any two nodes.

Common Mistakes: A common misunderstanding is that a ring topology also has bi-directional links between all nodes, but in a ring topology, nodes are only connected to their immediate neighbors.

Explanations: Mesh topology is characterized by the presence of bi-directional links between each possible node. This ensures that there are multiple paths between any two nodes, enhancing reliability and redundancy. In contrast, bus and ring topologies do not have bi-directional links between every node.

Option Analysis:

Option A: Bus topology has a single backbone to which all nodes are connected, not bi-directional links between each node.
Option B: Mesh topology has bi-directional links between each possible node, making it the correct answer.
Option C: Ring topology has nodes connected in a circular fashion, with each node connected to its immediate neighbors, not every node.
Option D: Not all the above topologies have bi-directional links between each possible node.

10. In a "chain"communication network, messages usually flow:

Correct Answer: Correct answer is: (B) Sequentially from one person to another.

Exam Relevance: Networking Fundamentals, CCNA, ITIL

Difficulty: Easy

Concept notes: In a "chain" communication network, messages are passed in a sequential manner from one person to the next, forming a linear path.

Common Mistakes: A common misunderstanding is that messages can flow randomly or directly to all members, which is not the case in a chain topology.

Explanations: In a chain communication network, each member communicates only with the adjacent members, creating a linear sequence. This means that messages flow sequentially from one person to the next, ensuring a direct and ordered path of communication.

Option Analysis:

Option A: This is incorrect because in a chain network, messages do not flow randomly between any two members. They follow a specific sequence.
Option B: This is correct because in a chain network, messages flow sequentially from one person to another, forming a linear path.
Option C: This is incorrect because a chain network does not restrict communication to only top-to-bottom flow. It can be in any direction along the chain.
Option D: This is incorrect because in a chain network, messages do not flow directly from the top to all members. They follow a sequential path.
