CWNA: Certified Wireless Network Administrator v107 — Question 27

The requirements for a WLAN you are installing state that it must support unidirectional delays of less than 150 ms and the signal strength at all receivers can be no lower than -67 dBm. What application is likely used that demands these requirements?

Answer options

• A. E-Mail
• B. RTLS
• C. VoIP
• D. FTP

Correct answer: B

Explanation

The correct answer is B (RTLS) because real-time locating systems require low latency and strong signal strength to function effectively. In contrast, A (E-Mail) and D (FTP) do not have strict timing requirements, and while C (VoIP) also requires low latency, RTLS has more stringent signal strength demands.
