QUESTIONS WITH CORRECT ANSWERS 2026
WhatZdoes Ia Iradio Irequire? I- ICORRECT IANSWER I-A Itransmitter, IA Ireceiver, Ithe Iover-
the- Iair Imedium Ibetween Ithe Itransmitter Iand Ireceiver
2.4Ghz Ihas Ia Ilonger Iwavelength Ithan I5Ghz Ibut Iis Imore Isusceptible Ito Iinterference. IThis Imeans... I-
ICORRECT IANSWER I-2.4Ghz Ihas Ilonger Irange Iand Ican Ipenetrate Ifloors Iand Iwalls.
Dynamic IFrequency ISelection I(DFS) Iallows Iwireless Idevices Ito I- ICORRECT IANSWERZ-
share Iparts Iof Ithe I5 Iand I6 IGhz Ifrequency. IA I5 Iand I6 IGhz Idevice Iwill Iuse IDFSZto Iswitch Ichannels Iif
Iradar IisZd Ietected.
2.4Ghz IBandsZ- ICORRECT IANSWER I-802.11, I802.11b, I802.11g, I802.11n, I802.11ax
5 IGhz IBands I- ICORRECT IANSWER I-802.11a, I802.11n, I802.11ac, I802.11ax
6 IGhz IBands I- ICORRECT IANSWER I-Wi-Fi I6E
,BeamformingZis Iused Iwith Iomnidirectional Iantennas I- ICORRECT IANSWER
I- Ito Iincrease Itheir Istrength Iin Ithe Idirection Iof Ithe Iconnected Iclient
Idevices
Spatial Istream I- ICORRECT IANSWER I-
is Ia Iwireless Idata Isignal Itransmitted Ior Ireceived Iby Ian Iantenna. IThe Imore Iantennas Ian Iaccess Ipoint
Ihas Ith Ie Imore Idata Iit Ican Ireceive/transmit Iat Ione Itime
If Ithe Inoise Ilevel Iis ItooZhigh I- ICORRECT IANSWER I-
it Ican Idegrade Ithe Istrength Iand Iperformance Iof Iyour Iwireless Isignals.
Power Iloss Ican Isignificantly Iaffect I- ICORRECT IANSWER I-
Ithe Irange Iand Ithroughput Iof Iyour Iwireless Idevices.
, Signal Istrength I- ICORRECT IANSWERZ-
is Ithe Iwireless Isignal Ipower Ilevel Ireceived Iby Ia Iwireless Iclient. IA Istrong Isignal Istrength Iresults Iin
Imore Ireli Iable IconnectionsZand Ihigher Ispeeds Ibut Ican Ialso Icause Iinterference Iwith Inearby Idevices.
AZdecibel I(dB) I-ZCORRECT IANSWER I-is Ia Irelative Imeasure Iof IRF Ipower.
AZwatt I-ZCORRECT IANSWER I-is Ian Iabsolute Imeasure Iof IRF Ipower
The Isignal Istrength Iis Irepresented Iin IdBm IformatZ(0 Ito I-100) I- ICORRECT IANSWER I-
This Iis Ithe Ipower Iratio Iin Idecibels I(dB) Iof Ithe Imeasured Ipower Ireferenced Ito Ione Imilliwatt I(mW).
The Icloser Ithe Ivalue Iis Ito I0 I- ICORRECT IANSWER I-the Istronger Ithe Isignal. IFor
Iexample, I- I45 IdBm Iis Ibetter Isignal Istrength Ithan I-65 IdBm
The Inoise Ilevel Iis Imeasured Iin IdBm Iformat I(0 Ito I-100 IdBm) I- ICORRECT IANSWER I-
This Iis Ithe Ipower Iratio Iin Idecibels I(dB) Iof Ithe Imeasured Ipower Ireferenced Ito Ione Imilliwatt.
The Icloser Ithe Ivalue Ito I0, Ithe Igreater Ithe Inoise Ilevel I- ICORRECT IANSWER I-
Negative Ivalues Iindicate Iless Ibackground Inoise. IFor Iexample, I-96 IdBm Iis Ia Ilower Inoise Ilevel
Ithan I- I20 IdBm.
