Question 10

A wireless engineer is utilizing the voice readiness tool in Cisco Prime for a customer that wants to deploy Cisco IP phones. Which dBm range is the network inspected against?

    Correct Answer: B

    The appropriate dBm range for voice readiness in a wireless network is typically between -72 dBm and -67 dBm. Cisco Prime often uses -72 dBm as the lower end of the acceptable signal strength range for reliable voice communication. Therefore, the correct answer is the option that falls within this range.

I'm logged into Prime 3.8 now, I selected one of our buildings, then a floor, then clicked "Inspect Voice Readiness" from the tools menu. With ''Cisco Phone' selected as client, the range is *not* editable, an it's -75dBm to -67dBm. So there is something wrong with this question and it's answers. No answer is right, and I've done a document search to try shed light on the correct answer and found nothing. Think very carefully about how you answer this!

CyborgXCZOption: B

Can confirm that Cisco Prime 3.10 has static value -75 to -67 so -72 could be consider as preferred value.

ShamsDimashkiOption: B

Always -67 is preferred

You will see different values for this signal level. Some references will refer to −75 dBm, and they mean the minimum signal (signal should be at least at −75 dBm). Others will mention −72 dBm as the “preferred” minimum, meaning that −75 dBm is acceptable, but −72 dBm will provide a better location estimation.

LiselotOption: D

-85 to -67 dBm (I guess the minus signs have forgotten in the answers)
