When measuring signal strength, dBm is commonly used and 0 dBm corresponds to 1 mW power.

What does -20 dBm correspond to?

A.-1 mW

B.01 mw

C10 mW

D1mW

Show Suggested Answer

Suggested Answer: B

dBm is a unit of power that measures the ratio of a given power level to 1 mW. The formula to convert dBm to mW is: P(mW) = 1mW * 10^(P(dBm)/10). Therefore, -20 dBm corresponds to 0.01 mW, as follows: P(mW) = 1mW * 10^(-20/10) = 0.01 mW Reference: https://www.rapidtables.com/convert/power/dBm_to_mW.html

I thought it would be more than that, but I guess not!

Yup, -20 dBm is .01 mW for sure.

Wait, is it really that low? Sounds off.

-20 dBm is actually 0.01 mW.

I’m not completely confident, but I feel like -20 dBm is less than 1 mW, maybe around 0.01 mW?

I vaguely recall that every 10 dBm change is a factor of 10 in power. So, -20 dBm should be 0.01 mW, right?

I think -20 dBm is actually 0.01 mW, but I might be mixing it up with another practice question we did.

I remember something about dBm being a logarithmic scale, but I'm not sure how to convert -20 dBm to mW.

Okay, let me see if I can figure this out. If 0 dBm is 1 mW, then -20 dBm must be less than that. I'm going to guess that it's 1 mW divided by 100, which is 0.01 mW. I'll select option B.

I remember learning about this in class. If 0 dBm is 1 mW, then each 3 dB decrease is a halving of the power. So -20 dBm must be 1/100th of 1 mW, which is 0.01 mW. I'll go with option B.

Hmm, this one's a bit tricky. I know dBm is a logarithmic scale, but I'm not sure how to convert -20 dBm to actual power. I'll have to think about this one a bit more.

Okay, let's think this through. If 0 dBm corresponds to 1 mW, then -20 dBm must be less than 1 mW. I'm pretty sure it's 0.01 mW, so I'll go with option B.

I'm feeling pretty confident about this one. I think the answer is to enable management access on the Cluster IP (CLIP) address, as that will ensure changes are made on the primary.

I'm pretty sure it's option B, g_form.addInfoMessage(). That sounds like the most straightforward way to print a message on a blue background to the top of the form.

I'm pretty confident the answer is A, 192.1.1.100. The virtual server IP is on the internal VLAN, and that's where the traffic is reaching the servers, so that should be the first IP used.
