Which of the following can cause wired network connectivity issues? (Select two.)
The correct answer is A. Loose or damaged Ethernet cables C. Mismatched duplex settings on network interfaces. Loose or damaged Ethernet cables (A) cause physical-layer failures - no signal means no connection. Mismatched duplex settings (C) create half/full duplex mismatches, leading to collisions, excessive errors, and severely degraded throughput, a classic "connected but slow or…

Explanation
Loose or damaged Ethernet cables (A) cause physical-layer failures - no signal means no connection. Mismatched duplex settings (C) create half/full duplex mismatches, leading to collisions, excessive errors, and severely degraded throughput, a classic "connected but slow or dropping" symptom.
Layer 3 switches (B) are a normal part of enterprise networks and actively improve routing efficiency - they don't cause connectivity problems. Enabling OSPF routing (D) is a dynamic routing protocol that helps networks find paths; it doesn't disrupt wired connectivity and is widely used without issue.
Memory tip: Think in OSI layers - connectivity problems trace to the Physical layer (cables) or Data Link layer (duplex/framing). If an answer involves a higher-layer protocol like OSPF or a device feature like L3 switching, it's managing traffic, not breaking links.
