Given that the device is not a WLAN device, you cannot use a protocol analyzer and have chosen to use a spectrum analyzer. You want to view the signal from the interfering device over time to see the activity that is generating.What common spectrum analyzer view should you use for this analysis?  APs  Waterfall/Spectrogram  Real-time FFT  Clients NEW QUESTION 68You 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?  Spectrum analysis to locate and identify RF interference sources.  Frequency-band hopping analysis to detect improper RF channel implementations.  Application analysis with an active phone call on an VoWiFi handset.  Protocol analysis to discover channel use on neighboring APs. NEW QUESTION 69A non-802.11 device is suspected of causing interference on the WLAN. You are not certain of the location or type of device. What is the best solution for locating this non-802.11 device?  Access point spectrum analyzer  Laptop-based spectrum analyzer with an omni-directional antenna  Laptop-based spectrum analyzer with a directional antenna  Laptop-based protocol analyzer with an omni-directional antenna NEW QUESTION 70The IEEE 802.11-2012 standard requires VHT capable devices to be backward compatible with devices using which other 802.11 physical layer specifications (PHYs)?  OFDM  HR/DSSS  ERP-PBCC  DSSS-OFDM ExplanationOFDM (Orthogonal Frequency Division Multiplexing) is the physical layer specification (PHY) that VHT capable devices must be backward compatible with according to the IEEE 802.11-2012 standard. VHT (Very High Throughput) is a PHY and MAC enhancement that is defined in the IEEE 802.11ac amendment and is also known as Wi-Fi 5. VHT operates only in the 5 GHz band and uses features such as wider channel bandwidths (up to 160 MHz), higher modulation schemes (up to 256-QAM), more spatial streams (up to eight), multi-user MIMO (MU-MIMO), beamforming, and VHT PHY and MAC enhancements. VHT can achieve data rates up to 6.9 Gbps.According to the IEEE 802.11-2012 standard, VHT capable devices must be backward compatible with devices using OFDM PHY, which is defined in the IEEE 802.11a amendment and is also used by IEEE802.11g, IEEE 802.11n, and IEEE 802.11h amendments. OFDM operates in both the 2.4 GHz and 5 GHz bands and uses features such as subcarriers, symbols, guard intervals, and OFDM PHY and MAC enhancements. OFDM can achieve data rates up to 54 Mbps.Backward compatibility means that VHT capable devices can interoperate with OFDM devices on the same network by using common features and parameters that are supported by both PHYs. For example, VHT capable devices can use a channel bandwidth of 20 MHz, a modulation scheme of BPSK, QPSK, or 16-QAM, one spatial stream, no beamforming, and OFDM PHY and MAC headers when communicating with OFDM devices. Backward compatibility also means that VHT capable devices can fall back to OFDM mode when the signal quality or SNR is too low for VHT mode.

What is the most important factor in determining the impact of this non-802.11 device?  Receive sensitivity  Channel occupied  Airtime utilization  Protocols utilized ExplanationAirtime Utilization is a per-channel statistic that defines what percentage of the channel is currently being used, and what percentage is therefore free. Airtime usage can come from: Data traffic to and from client devices. Interference from WiFi and non-WiFi sources. Management overhead from APs and client devices.https://wyebot.com/2019/06/06/understanding-airtime-utilization/NEW QUESTION 72As a consultant, you’ve been hired by XYZ Company to provide recommendations about client device selection, operation, and interoperability. What information should be considered to help them choose the right WLAN client devices?  802.11n OFDM is more susceptible to high-power, narrowband interference than 802.11a  In order to earn Wi-Fi Alliance certification, 802.11n clients stations are required to support both2.4 and 5 GHz frequencies  802.11ac devices support the features of the VHT PHY only in the 5 GHz frequency band.  802.11ac is not backwardly compatible with 802.11n or 802.11a.  When HR/DSSS devices are present, VHT MCS rates are disabled for the entire BSS. NEW QUESTION 73You are onsite with a client to perform a post-deployment site survey. When verifying a multiple channel VoWiFi deployment using a VoWiFi handset, which aspect is most important?  Performing protocol analysis with a single wireless adapter that is scanning all channels in use  Testing a constant conversation orhandset tone while roaming from area to area, or performing an active survey  Configuring DSCP-to-802.11e QoS maps on the handset for each access category.  Verifying the VHT functionality to handle the call volume incurred by a single VoIP phone call. NEW QUESTION 74To ease user complexity, your company has implemented a single SSID for all employees. However, the network administrator needs a way to control the network resources that can be accessed by each employee based in their department.What WLAN feature would allow the network administrator to accomplish this task?  RBAC  WPA2  WIPS  SNMP ExplanationThe WLAN feature that would allow the network administrator to control the network resources that can be accessed by each employee based on their department is Role-Based Access Control (RBAC). RBAC is a method of assigning different permissions and policies to users or groups based on their roles in the organization. RBAC can be implemented by using VLANs, ACLs, or firewalls to restrict access to certain network segments or resources. RBAC can also be integrated with 802.1X/EAP authentication to dynamically assign roles and VLANs to users based on their credentials.

When you evaluate the situation, you see that the signal strength is -84 dBm and the noise floor is -96 dBm. The client is an 802.11ac client and connects to an 802.11acAP. Both the client and AP are 2×2:2 devices.What is the likely cause of the low data rate issue?  Weak signal strength  Too few spatial streams  Lack of support for 802.11n  CAT5e cabling run to the AP NEW QUESTION 77In a mesh BSS (MBSS), according to the 802.11-2016 standard, what device connect the mesh to an Ethernet network?  Mesh Gate  Mesh Switch  Mesh Router  Mesh Portal The function of an AP that performs this translation between the wireless network and the wired network (as with M and P) is called the portal. The portal is a function. It is just the logical point where wireless MSDUs are translated to and from a non-802.11 network (802.11-2007, def 3.39 and 3.110). An AP commonly performs the portal function. M, and P are APs and portals.https://www.cwnp.com/uploads/802-11s_mesh_networking_v1-0.pdfhttps://s2.smu.edu/~camp/pubs/mesh80211s.pdfNEW QUESTION 78In an 802.11n WLAN with a heterogeneous set of associated client devices including 802.11b,11g, and 11n, what HT protection mode will the BSS use?  Mode 0: No protection mode (Greenfield)  Mode 1: Nonmember protection mode  Mode 2: 20 MHz protection mode  Mode 3: Non-HT mixed mode NEW QUESTION 79The 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?  VoIP  E-Mail  FTP  RTLS NEW QUESTION 80In a long-distance RF link, what statement about Fade Margin is true?  A Fade Margin is unnecessary on a long-distance RF link if more than 80% of the first Fresnel zone is clear of obstructions.  The Fade Margin is a measurement of signal loss through free space and is a function of frequency and distance.  Fade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading.  The Fade Margin of a long-distance radio link should be equivalent to the receiver’s low noise filter gain. ExplanationFade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading. It is the difference between the receiver’s sensitivity and the actual received signal level. A higher Fade Margin indicates a more robust link that can withstand interference, attenuation, or other factors that may reduce the signal strength. A lower Fade Margin means that the link is more susceptible to failure or performance degradation. Fade Margin is usually expressed in decibels (dB) and can be calculated by subtracting the receiver sensitivity from the received signal level.
