What component of the 802.11 standard allows stations to reserve access to the RF medium for a specified period of time?  Short guard intervals  DTIM Interval  Listen Interval  Probe Request frames  RTS or CTS frames Q29. You are the network administrator for ABC Company. Your manager has recently attended a wireless security seminar. The seminar speaker taught that a wireless network could be hidden from potential intruders if you disabled the broadcasting of the SSID in Beacons and configured the access points not to respond to Probe Request frames that have a null SSID field.Your manager suggests implementing these security practices. What response should you give to this suggestion?  Any 802.11 protocol analyzer can see the SSID in clear text in frames other than Beacons frames. This negates any security benefit of trying to hide the SSID in Beacons and Probe Response frames.  To improve security by hiding the SSID, the AP and client stations must both be configured to remove the SSID from association request and response frames. Most WLAN products support this.  Any tenants in the same building using advanced penetration testing tools will be able to obtain the SSID by exploiting WPA EAPOL-Key exchanges. This poses an additional risk of exposing the WPA key.  This security practice prevents manufacturers’ client utilities from detecting the SSID. As a result, the SSID cannot be obtained by attackers, except through social engineering, guessing, or use of a WIPS. Q30. Which IEEE 802.11 physical layer (PHY) specifications include support for and compatibility with both ERP and HR/DSSS?  VHT (802.11ac)  OFDM (802.11a)  DSSS (802.11-Prime)  HT (802.11n) Q31. Which of the following frequency ranges are specified for use by IEEE 802.11 radios? (Choose all that apply.)  902 – 928 MHz  2.4000 – 2.4835 GHz  5.15 – 5.25 GHz  5.470 – 5.725 GHz  5.725 – 5.875 GHz Q32. The requirements for a WLAN you are installing state that it must support unidirectional delays of less than150 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 Q33. What statement is true concerning the use of Orthogonal Frequency Division Multiplexing (OFDM) modulation method in IEEE 802.11 WLANs?  OFDM implements BPSK modulation to allow for data rates up to 7 Gbps.  OFDM was first introduced in 802.11a and is used by the ERP, HT and VHT PHYs as well.  OFDM modulation is used only in 5 GHz 802.11 transmissions.  OFDM was used by Frequency Hopping Spread Spectrum (FHSS) PHY devices. Q34. Return Loss is the decrease of forward energy in a system when some of the power is being reflected back toward the transmitter.What will cause high return loss in an RF transmission system, including the radio, cables, connectors and antenna?  The use of cables longer than one meter in the RF system  High output power at the transmitter and use of a low-gain antenna  A Voltage Standing Wave Ratio (VSWR) of 1:1  An impedance mismatch between components in the RF system Q35. What terms accurately complete the following sentence?The IEEE 802.11-2016 standard specifies mandatory support of the _______________ cipher suite for Robust Security Network Associations, and optional use of the ________________ cipher suite, which is designed for use with pre-RSNA hardware and is deprecated.  802.1X/EAP, WEP  CCMP, TKIP  TLS, SSL  RC5, RC4 Q36. Users and Network support personnel at a mid-sized equipment manufacturer have been discussing the potential uses and benefits of implementing an indoor WLAN. The network administrator and network manager have requested a meeting of senior management personnel to discuss a WLAN implementation before performing a site survey or taking any implementation steps. The first topic of discussion in the meeting is the corporate policy concerning implementation and use of WLAN technology.What specific topics are appropriate in this policy meeting? (Choose 2)  Use of the latest 802.11ac equipment  Business justification  User productivity impact  Antenna types  Defining RF channels for use Q37. What is a channel mode specified by the 802.11n (High Throughput) PHY?  Frequency Hopping  20/40 MHz  22 MHz  80 MHz Q38. What term correctly completes the following sentence?In an IEEE 802.11 frame, the IP packet is considered by the MAC layer to be a(n) _________.  MAC Service Data Unit (MSDU)  MAC Protocol Data Unit (MPDU)  IP datagram  PLCP Service Data Unit (PSDU)  PLCP Protocol Data Unit (PPDU) Q39. What is an advantage of using WPA2-Personal instead of WEP-128 as a security solution for802.11 networks?  WPA2-Personal uses CCMP for encryption, and WEP-128 uses TKIP for encryption  WPA2-Personal uses dynamic encryption keys, and WEP-128 uses static keys  WPA2-Personal uses 802.1X/EAP for authentication, and WEP-128 uses preshared keys  WPA2-Personal is based on IEEE 802.11 industry standards, but WEP is not Q40. As XYZ Company’s wireless specialist, you have been asked to troubleshoot some unexpected frame patterns in a wireless protocol capture. Your peers explain that the network’s beacon frames are inconsistent. That is, the BSSID is the same for all beacons, but the source address varies between three different addresses.What network configuration would cause this beacon frame behavior?  A single AP supports multiple BSSs with different SSIDs  A virtual cell single channel network has been implemented  The beacons are from an IBSS instead of a BSS  Three APs still share the same default configuration. Q41. Which one of the following frequency ranges is not specified for use by IEEE 802.11 radios as of802.11-2012?  600-630 MHz  2.4000-2.4835 MHz  5.725-5.874 GHz  5.15-5.25 GHz Q42. Your consulting firm has recently been hired to complete a site survey for a company. Your engineers use predictive modeling software for surveying, but the company insists on a pre- deployment site visit.What task should be performed as part of the pre-deployment visit to prepare for a predictive survey?  Evaluatethe building materials at ABC’s facility and confirm that the floor plan documents are consistent with the actual building.  Test several antenna types connected to the intended APs for use in the eventual deployment.  Collect information about the company’s security requirements and the current configuration of their RADIUS and user database servers.  Install at least one AP on each side of the exterior walls to test for co-channel interference through these walls. Q43. The IEEE 802.11-2012 standard requires VHT capable devices to be backward compatible with devices using which other 802.11 physical layer specification (PHY)?  OFDM  HR/DSSS  ERP-PBCC  DSSS  Loading … Use Free CWNA-108 Exam Questions that Stimulates Actual EXAM : https://www.actualtests4sure.com/CWNA-108-test-questions.html --------------------------------------------------- Images: https://blog.actualtests4sure.com/wp-content/plugins/watu/loading.gif https://blog.actualtests4sure.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2022-11-02 14:10:13 Post date GMT: 2022-11-02 14:10:13 Post modified date: 2022-11-02 14:10:13 Post modified date GMT: 2022-11-02 14:10:13
