Network Hardware

Correct Answer: Network analyzer

A Network analyzer is the best tool for monitoring network traffic in real time and can be used to troubleshoot intermittent connectivity issues. It provides statistics, data flows, and the performance of the network, enabling the network administrator to identify issues precisely. A Cable tester, on the other hand, would be used to test the strength and connectivity of a physical cable such as ethernet, they are not for real-time monitoring. Antivirus software is more about computer security, it doesn't allow for real-time network monitoring. A Multimeter is used to monitor voltage, current, and resistance, it does not provide real-time monitoring of network traffic.

Correct Answer: Switch

A 'Switch' is the ideal hardware for connecting multiple wired devices in a small network. It uses MAC addresses to forward data to the correct destination. While 'Router' is sometimes a good fit, it is mainly used for connecting different networks instead of devices within the same network. An 'Access Point' is typically for wireless connections, not wired ones. Finally, a 'Hub', an older technology, also connects devices, but it broadcasts incoming traffic to all connected devices without considering the destination, which is less efficient and secure than a 'Switch'.

Correct Answer: Confirm the printer is on the correct VLAN

The best answer is to 'Confirm the printer is on the correct VLAN'. A VLAN (Virtual Local Area Network) is used to group together devices that are on separate physical networks. If a device is not on the correct VLAN, it will not be able to communicate with the other devices on that VLAN. Therefore, to make the new network printer visible to the users, its VLAN configuration should be checked to ensure that it is on the correct VLAN The other answers are not as appropriate: 'Enable WEP encryption' might be useful for securing a wireless printer, but it doesn't deal directly with device visibility on the network. 'Disable firewall on user computers' would not be recommended in this situation, as this could lead to security vulnerabilities and wouldn't necessarily make the printer visible on the network. 'Enable jumbo frames on the printer' could improve network performance but again isn't directly tied to network device visibility either.
