An office is experiencing intermittent connection issues. A network engineer identifies that the issue occurs whenever someone uses the fax machine that is connected to a switch. Which of the…

Running a new Cat 5 line would address a physical cable fault, but the issue is intermittent and specifically linked to the fax machine's usage, suggesting a logical network problem rather than a damaged cable.

Enabling 802.1Q tagging is a component of VLAN implementation, but it is not the complete solution; the engineer needs to actually define and configure the VLANs and assign the fax machine's port to it.

Changing the MTU (Maximum Transmission Unit) primarily addresses network fragmentation or performance tuning for specific packet sizes, which is unlikely to resolve intermittent connection issues caused by a device's general network activity.

Configuring a VLAN (Virtual Local Area Network) for the fax machine isolates its network traffic from the main office network. This segmentation prevents any potential broadcast storms, excessive traffic, or misconfigurations from the fax machine from interfering with other devices and causing intermittent connection issues.
