Q: 5
Which unit of measurement, as formally defined, is an absolute unit that is used to quantify received
signal power levels on a logarithmic scale?

Option C, not D. dBi looks tempting since it's common in wireless but that's antenna gain, not received signal power. Seen similar questions in practice banks, almost always C for absolute/log unit here.
C. not D. dBm is absolute, dBi measures antenna gain so it's a common trap. Pretty sure C from similar exam reports.
Option C is right since dBm is an absolute unit referenced to 1 mW, not a relative one like dBi. Got tripped up by this on some practice sets before. Always double check if they're asking for power or antenna gain.
Why not D if the question was about measuring antenna gain instead of received signal power?
Yeah, it's definitely C. dBm is the absolute unit for received signal strength on a log scale. dBi trips people up since it's relative (antenna gain), not absolute. Seen this exact kind of wording come up in a lot of CWNA practice sets.
Probably C. dBm is the only absolute unit here, while dBi is often a trap since it's relative antenna gain.
C for this, seen it called out clearly in the CWNA official guide and practice tests.
Seen this a lot in practice exams and the official study guide. C is it, since dBm is an absolute unit for measuring received power on a log scale. The others are either not absolute or used for something else (like antenna gain). I’m pretty confident, but open to corrections if someone has different context.
C , but if they’d asked about relative gain for antenna, D would flip as correct. Just how CWNP words these sometimes.
C imo, dBm is absolute and quantifies received power using a logarithmic scale. dBi is about antenna gain, not received signal power. I think C lines up with the CWNA guide, but let me know if you see it differently.
