Question #22
You have been asked to design a high-density wireless network for a university campus. Which two principles would you apply in order to maximize the wireless network capacity? (Choose two.)
- AChoose a high minimum data rate to reduce the duty cycle.
- BMake use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual-band clients are used.
- CEnable 802.11n channel bonding on both 2.4 GHz and 5 GHz to increase the maximum aggregated cell throughput.
- DIncrease the number of SSIDs to load-balance the client traffic.
- EImplement a four-channel design on 2.4 GHz to increase the number of available channels.
Correct Answer:
AB
AB
GPT-4o - Answer
Right on, choosing a higher minimum data rate does indeed help in shrinking the duty cycle. This means less airtime is used per data unit, which helps squeeze more out of your available bandwidth, boosting the overall network capacity. Also, swinging for the 5-GHz band cuts down on the congestion typically seen on the 2.4 GHz band, especially when you’ve got dual-band clients in the mix. This switch not only provides cleaner channels but also supports higher data rates, which is exactly what you want in a packed campus environment. Both principles are crucial in beefing up your network’s ability to handle more traffic smoothly.
Question #23
Which optimal use of interface dampening on a fast convergence network design is true?
- Awhen the switch hardware is faster than the debounce timer down detection
- Bwhen numerous adjacent flaps of very short duration occur
- Cwhen occasional flaps of long duration occur
- Dwhen the router hardware is slower than the carrier delay down detection
Correct Answer:
B
B
GPT-4o - Answer
Interface dampening is particularly potent in environments where you've got a bunch of quick, successive link flaps. What dampening does is quite clever - instead of reacting to every single flap (which might just overload your network with redundant recalculations), it temporarily suppresses the "flappiness" of the interface. This means your network doesn't get thrown off by every minor disruption, maintaining better overall stability and performance. It's like a built-in buffer against chaos in your network design – super handy for keeping things running smoothly!
