Question

Accepted Answer

Answering questions related to crimping, UTP fiber, VLANs, and the difference between hub and switch for a Network Engineer position.

Crimping RJ45 connectors onto UTP cables is a common task for network engineers. Advantages include ease of installation and cost-effectiveness. Disadvantages include susceptibility to interference and limited distance.
UTP fiber cables offer higher bandwidth and longer distances than UTP cables. Advantages include immunity to electromagnetic interference and better security. Disadvantages include higher cost and more difficult installation.
VLANs are used to segment a network into smaller, more manageable subnetworks. Benefits include improved security, better performance, and easier management. Categories of VLANs include port-based, MAC-based, and protocol-based.
Hubs and switches are both used to connect devices on a network. However, switches are more intelligent and efficient than hubs. Switches use MAC addresses to forward data to the correct device, while hubs broadcast data to all devices on the network.
