Part 1.5

Given a scenario where a business needs high-speed wireless connectivity within an office building, which 802.11 standard would be most appropriate to recommend for maximum throughput?

• 802.11a

• 802.11n

• 802.11b

• 802.11g

A network engineer is deciding between single-mode and multimode fiber for a 10 km link. Which type should they choose and why?

• Multimode fiber, because it supports longer distances

• Single-mode fiber, because it supports longer distances

• Multimode fiber, because it is less expensive for long distances

• Single-mode fiber, because it is less expensive for short distances

If a data center requires a low-latency, short-distance, high-speed connection between two switches, which cable type is most suitable?

• Coaxial cable

• Direct Attach Copper (DAC)

• Single-mode fiber

• Plenum cable
