Correct Answer: Configure 802.1Q tagging with a higher priority for VoIP traffic

The best method to ensure that the VoIP traffic has a higher priority is to 'Configure 802.1Q tagging with a higher priority for VoIP traffic'. This is because 802.1Q tagging, or VLAN tagging, provides the ability to logically segment a LAN into separate broadcast domains. By assigning a higher priority to VoIP traffic through QoS or Quality of Service, the switch can prioritize the VoIP packets during times of high network usage. Therefore, this aids in preventing voice quality degradation. On the other hand, 'Enable Network Address Translation', 'Enable port mirroring' and 'Configure SNMP monitoring' though important networking procedures themselves, are not directly related to improving the priority of VoIP traffic. Network Address Translation or NAT helps in modifying network address information in packet headers for different IP routing purposes. Port mirroring is often used for network appliances requiring to monitor network traffic. SNMP monitoring is used to manage network performance, find and solve network issues, and plan for network growth. None of these methods inherently provide a method to increase priority for chosen traffic like 802.1Q tagging does.

Correct Answer: Cable tester

The tool best suited to identify a break in the Ethernet cable is a Cable tester. A Cable tester is specifically designed to check for issues such as breaks or faults in the cable, ensuring the cable's proper functioning. A Crimper tool, on the other hand, is used to join two pieces of metal or other malleable materials by deforming one or both of them to hold the other. Thus, it is not relevant in identifying a break in the cable. A Patch panel is a device that serves as a conduit for cable connections, but it is not a tool for diagnosing cable issues. Lastly, a Tone generator is a device used to apply specific types of tones to a line for tracing and identifying it but it does not identify a break in the cable.

Correct Answer: Managed switch, 802.1Q

A Managed switch is used for creating VLANs as it allows for control and configuration of the ports and traffic, whereas an Unmanaged switch does not. Additionally, the 802.1Q standard is related to VLAN implementation and tagging. So, 'Managed switch, 802.1Q' is the correct answer. On the other hand, 'Unmanaged switch, 802.1Q' and 'Unmanaged switch, 802.3ab' are incorrect because an Unmanaged switch cannot create VLANs. 'Managed switch, 802.3ab' is also incorrect as 802.3ab standard is related to Gigabit Ethernet over copper wiring and not VLANs.
