A network administrator is choosing fiber for a link inside a data center, with a maximum distance of 300 meters. Which fiber type and light source combination is most appropriate?

Coaxial cable with a laser light source

Single-mode fiber with a laser light source

Multimode fiber with an LED or VCSEL light source

Multimode fiber with a laser light source exclusively

A legacy network uses a hub to connect several PCs. The administrator notices frequent collisions during peak usage. What is the primary cause of these collisions?

The PCs are using full-duplex mode, which is not supported by hubs

The PCs are using different Ethernet speeds

The UTP cabling is too long, exceeding the 100-meter limit

The hub creates a single collision domain where all devices share the same bandwidth

A network administrator is connecting two switches with a fiber link. The link is configured for full-duplex. What is a direct benefit of this configuration?

Simultaneous data transmission and reception

A network engineer is connecting two routers directly with a fiber cable. The link is configured for full-duplex. What is true about this link?

The link can only transmit in one direction at a time

The link requires a crossover cable

The link does not require CSMA/CD

The link is more susceptible to collisions than half-duplex
