Which of the following options are factors that affect the performance of the front-end host port? (Multiple choice)

Question

Options

• AConcurrency pressure on the front-end host.
• BThe type of business processed by the front-end host port.
• CFront-end host port performance indicators.
• DFront-end host port information.
• EIs there any bit error on the front-end host port?

• A
  76% (19)
• B
  24% (6)

Explanation

Four factors directly govern front-end host port performance: concurrency pressure (A) increases load and can saturate the port; port performance indicators (C) such as throughput and latency metrics define and bound the port's operational capacity; port information (D) - configuration details like link speed, duplex mode, and capacity limits - sets the physical ceiling on what the port can handle; and bit errors (E) degrade signal integrity, causing retransmissions and reducing effective throughput.

Option B is incorrect because the type of business is too abstract and indirect - it does not itself act on port performance. What matters are the measurable traffic characteristics and physical port properties captured by the other four options, not a business category label.

Memory tip: Think of port performance as governed by who's pushing data (A), what the port can do (C & D), and how cleanly data travels (E) - the business label (B) is just a description, not a performance lever.
