CompTIA CNX-001 Exam - Topic 2 Question 14 Discussion

Actual exam question for CompTIA's CNX-001 exam

Question #: 14
Topic #: 2

A network administrator must connect a remote building at a manufacturing plant to the main building via a wireless connection. Which of the following should the administrator choose to get the greatest possible range from the wireless connection? (Choose two.)

A2.4GHz

B5GHz

C6GHz

DOmnidirectional antenna

EPatch antenna

FBuilt-in antenna

Show Suggested Answer

Suggested Answer: A, E

2.4 GHz: The lower-frequency 2.4 GHz band propagates farther and better penetrates obstacles than 5 GHz or 6 GHz, giving you greater link distance.

Patch antenna: A directional (patch) antenna focuses RF energy into a narrow beam, maximizing gain and range between two fixed points -- the best for a long-haul wireless link.

Haha, who uses 6GHz these days? That's so 2030.

I agree, 2.4GHz and an omnidirectional antenna will give the best range.

I thought 5GHz was better for speed, but for range, I guess 2.4GHz is the way to go, right?

I'm not entirely sure, but I feel like the patch antenna could provide better directionality for long distances.

I think I practiced a similar question where the omnidirectional antenna was a good choice for covering a wide area.

I remember that the 2.4GHz band has a longer range compared to 5GHz, but it can be more crowded with interference.

The key here is maximizing range for the wireless connection. So I'm going to go with 2.4GHz and the omnidirectional antenna. The 2.4GHz frequency has better propagation characteristics, and the omnidirectional pattern will ensure coverage in all directions from the remote building.

I'm a little confused on the antenna types. Is the omnidirectional better than the patch for range? And I'm not familiar with 6GHz, so I'm not sure if that's a real option. Guess I'll have to review my wireless networking knowledge before answering this.

Okay, I've got this. The 2.4GHz frequency and the omnidirectional antenna are the way to go for maximum range. The 5GHz and 6GHz options have shorter ranges, and the patch antenna is more directional. Feeling confident about this one!

Hmm, I'm not sure about this one. I know 2.4GHz has better range, but I'm not sure if 6GHz is an actual wireless frequency option. And what's the difference between the antenna types? I'll have to think this through carefully.

I think the answer is 2.4GHz and Omnidirectional antenna. The 2.4GHz frequency has better range than 5GHz, and the omnidirectional antenna will provide coverage in all directions.
