A network administrator is troubleshooting a network with a hub. Users report slow performance. The administrator suspects collisions. What is the most effective way to confirm and resolve the issue?

Replace all UTP cables with STP cables

Check the hub's collision counter and replace the hub with a switch

A network engineer is troubleshooting intermittent connectivity on a legacy Ethernet segment that uses a hub. The engineer notices that the link is operating in half-duplex. What is the most likely cause of the intermittent connectivity?

Duplex mismatch between the hub and a connected device

Collisions due to the shared medium

Electromagnetic interference from nearby equipment

Attenuation due to excessive cable length

A network administrator is troubleshooting a legacy network where multiple computers are connected to a hub. Users complain of slow performance and frequent timeouts. The administrator suspects collisions. What is the best way to reduce collisions in this network?

Increase the hub's transmission power

Use longer cables to reduce interference

What is a key characteristic of a point-to-point Ethernet connection?

It requires a hub to connect multiple devices

It shares bandwidth among all connected devices

It operates in half-duplex mode and uses CSMA/CD

It provides dedicated bandwidth and can operate in full-duplex mode

A network administrator is connecting two switches directly with a fiber link. The link is configured for full-duplex. Which statement is true about this connection?

The link creates a single collision domain for both switches

The link uses CSMA/CD to avoid collisions

The link requires a hub to operate

The link is a point-to-point connection with dedicated bandwidth in each direction
