NEW QUESTION # 158
You were previously onsite at XYZ's facility to conduct a pre-deployment RF site survey. The WLAN has been deployed according to your recommendations and you are onsite again to perform a post-deployment validation survey.
When performing this type of post-deployment RF site survey voice over Wi-Fi, what is an action that must be performed?
Answer: C
Explanation:
When performing a post-deployment validation survey for voice over Wi-Fi (VoWiFi), an action that must be performed is Application analysis with an active phone call on a VoWiFi handset. Application analysis is a method of testing the performance of a specific application over the WLAN by measuring parameters such as throughput, latency, jitter, packet loss, MOS score, and R-value. Application analysis with an active phone call on a VoWiFi handset can help to evaluate the quality of service (QoS) and user experience of VoWiFi calls over the WLAN. It can also help to identify any issues or bottlenecks that may affect VoWiFi calls such as interference, roaming delays, or insufficient coverage.

NEW QUESTION # 159
You are tasked with performing a throughput test on the WLAN. The manager asks that you use open source tools to reduce costs. What open source tool is designed to perform a throughput test?
Answer: A
Explanation:
iPerf is an open source tool that is designed to perform a throughput test on the WLAN. iPerf is a cross-platform command-line tool that can measure the bandwidth and quality of network links by generating TCP or UDP traffic between two endpoints.iPerf can run as either a server or a client mode, depending on whether it receives or sends traffic. iPerf can also report various metrics of network performance, such as throughput, jitter, packet loss, delay, and TCP window size. To perform a throughput test on the WLAN using iPerf, one device needs to run iPerf in server mode and another device needs to run iPerf in client mode. The devices need to be connected to the same WLAN network and have their IP addresses configured properly.
The device running iPerf in client mode needs to specify the IP address of the device running iPerf in server mode as well as other parameters such as protocol, port number, duration, interval, bandwidth limit, packet size, etc. The device running iPerf in server mode will listen for incoming connections from the client device and send back acknowledgments or responses depending on the protocol used. The device running iPerf in client mode will send traffic to the server device according to the specified parameters and measure the network performance. The device running iPerf in client mode will display the results of the throughput test at the end of the test or at regular intervals during the test. The results can show the average, minimum, maximum, and instantaneous throughput of the network link, as well as other metrics such as jitter, packet loss, delay, and TCP window size.

NEW QUESTION # 160
A wireless engineer wants to enable both legacy 802.11b clients and modern 802.11ax clients to associate with the same 2.4 GHz SSID. What is a drawback of enabling this level of backward compatibility?
Answer: C
Explanation:
When a BSS supports both legacy 802.11b clients and newer high-throughput clients like
802.11ax, protection mechanisms such as RTS/CTS or CTS-to-Self must be used to prevent collisions between devices using different modulation schemes that cannot always detect each other's transmissions. These protection mechanisms consume additional airtime and overhead, reducing the overall throughput and efficiency available to all clients in the BSS, including the newer, faster devices. For this reason, many administrators choose to disable 802.11b data rates entirely on modern networks.
NEW QUESTION # 161
In an 802.1X/EAP authentication exchange, what device acts as the "authenticator" that relays authentication messages between the client and the authentication server?
Answer: B
Explanation:
In an 802.1X/EAP framework, there are three roles: the supplicant, which is the client device requesting network access; the authenticator, which is the access point or WLAN controller that controls access to the network and relays EAP messages between the supplicant and the authentication server; and the authentication server, typically a RADIUS server, which validates the credentials and makes the final access decision. The authenticator does not make authentication decisions itself; it simply passes messages back and forth and enforces the outcome.
NEW QUESTION # 162
In an 802.11n (H T) 2.4 GHz BSS, what prevents each station from using all the airtime when other client stations are actively communicating in the same BSS?
Answer: B
Explanation:
What prevents each station from using all the airtime when other client stations are actively communicating in the same BSS is CSMA/CA. CSMA/CA stands for Carrier Sense Multiple Access with Collision Avoidance and is a media access control method used by WLAN devices to share the wireless medium. CSMA/CA works by having each station sense the medium before transmitting a frame. If the medium is busy (i.e., another station is transmitting), the station defers its transmission until the medium is idle. If the medium is idle, the station waits for a random backoff period before transmitting. This way, CSMA/CA reduces the chances of collisions and ensures fair access to the medium for all stations. CSMA/CA also uses positive acknowledgements to confirm successful transmissions and retransmissions to recover from errors. CSMA
/CD, DOS prevention, and OFDMA are not used by WLAN devices in a BSS. References: [CWNP Certified Wireless Network Administrator Official Study Guide: Exam CWNA-109], page 108; [CWNA: Certified Wireless Network Administrator Official Study Guide: Exam CWNA-109], page 98.
