200-301 Question #1468: Real Exam Question with Answer & Explanation

Question

Which interface condition is occurring in this output?

Options

• Abad NIC
• Bbroadcast storm
• Cduplex mismatch
• Dhigh throughput

Explanation

Assuming the interface output indicates a large volume of data successfully processed with minimal errors, the condition occurring is high throughput.

Common mistakes.

• A. A bad NIC typically manifests as an interface status down, excessive errors (e.g., CRC errors, input errors, collisions), or intermittent connectivity issues, which would impede, not indicate, high throughput.
• B. A broadcast storm is characterized by an excessive amount of broadcast traffic, often leading to network congestion, high CPU utilization on network devices, and potentially high discard rates or errors, which is distinct from healthy high throughput.
• C. Duplex mismatch occurs when one side of a link operates in full-duplex and the other in half-duplex, resulting in a high number of late collisions, input errors, and generally poor performance, rather than simply high throughput.
