Discuss CompTIA CNX-001 Exam Topic 2 Question 18

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.)

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.

I think 2.4GHz is a good choice for range.

Kimbery 8 days ago

I’m convinced!

Jordan 13 days ago

Overall, 2.4GHz and omnidirectional seems best.

Arlene 18 days ago

Right, obstacles can affect performance.

Flo 23 days ago

Let’s not forget about the environment too.

Ahmed 28 days ago

I still think 2.4GHz is the safest bet.

Louisa 1 month ago

Exactly, not ideal for wide coverage.

Alberto 1 month ago

But it’s more directional, right?

Kati 1 month ago

Patch antenna could also help focus the signal.

Kimbery 2 months ago

Yes, that combo should cover more area.

Jordan 2 months ago

I’d go with 2.4GHz and an omnidirectional antenna.

Arlene 2 months ago

True, but it has a shorter range.

Flo 2 months ago

But 5GHz has less interference.

Ahmed 2 months ago

Agreed, it penetrates walls better.

Louisa 2 months ago

I think 2.4GHz is a good choice for range.

Pearly 3 months ago

I’m not sure about the patch antenna, seems risky.

Ammie 3 months ago

Wait, is 6GHz even a good option for this?

Zoila 3 months ago

5GHz has better speed, but range? Nah.

Billye 3 months ago

I’d pick the omnidirectional antenna too.

Karan 3 months ago

Definitely go with 2.4GHz for range!

Jesus 4 months ago

I’m a bit confused; I thought 5GHz had better speed but shorter range. Does that mean it’s not ideal for this situation?

Elvera 5 months ago

I practiced a similar question, and I think 2.4GHz and an omnidirectional antenna could be the best combo for range.

Eve 5 months ago

I think the omnidirectional antenna would be a good choice for coverage, but I'm not sure about the frequency.

Denise 5 months ago

I remember that the 2.4GHz band has a longer range but is more prone to interference.
