What could be the cause of intermittent wired connectivity issues?

• A. Signal interference
• B. Router misconfiguration
• C. Switch port state changes
• D. Driver incompatibility

Answer: (C)

Intermittent wired connectivity issues can often stem from changes in the state of switch ports. When a switch port changes states—such as transitioning from "up" to "down"—it can disrupt the connection intermittently. This could occur due to physical issues like a loose cable connection, a faulty switch port, or improper VLAN configurations that affect how devices communicate across the network. These disruptions can lead to devices being unable to send or receive data consistently, which is characteristic of intermittent connectivity problems. While other options like signal interference, router misconfiguration, and driver incompatibility can affect network performance, they are typically more associated with specific types of connectivity issues rather than the unpredictable nature of intermittent problems. Signal interference generally pertains to wireless connections or electromagnetic interference in wired networks but does not directly relate to wired connection drops. Router misconfiguration can lead to persistent issues rather than intermittent ones, where the configuration is incorrect but remains so. Driver incompatibility typically relates to communication issues between the operating system and hardware but is less likely to cause sporadic behavior. Thus, the best choice for explaining the cause of intermittent wired connectivity is linked to the dynamic state changes of switch ports.
