Question 1

Which network topology provides the highest fault tolerance by connecting every node to every other node?

Accepted Answer

Mesh topology

Answer

A full mesh topology connects every node directly to every other node, ensuring no single point of failure can isolate any device.

Question 2

What is the primary purpose of a demilitarized zone (DMZ) in network architecture?

Accepted Answer

To host public-facing services while protecting the internal network

Question 4

What does VLAN segmentation primarily achieve in an enterprise network?

Accepted Answer

Logically separates network traffic without requiring physical separation

Answer

VLANs create logical network segments on shared physical infrastructure, reducing broadcast domains and improving security and manageability.

Question 5

In a three-tier network architecture, which tier handles routing between different network segments?
