                          CWNP Certified Wireless Analysis Professional Sample Questions:

                          Question #1
                          You have implemented an AP at a remote office. It is a single-band AP supporting
                          802.11ac. Several users complain that their laptops cannot connect to the WLAN. These laptops are from multiple vendors and range in age from 2 to 4 years. The SSID and security profile settings are correct. All default settings were used on the AP with the exception of the SSID and security settings.
                          What is the most likely issue preventing these STAs from connecting to the AP?

                          A. They are 5 GHz-only devices
                          B. They do not support VHI and only support OFDM
                          C. They are 2.4 GHz-only devices
                          D. They do not support the basic data rates


                          Question #2
                          VoIP is used heavily in your organization. You must troubleshoot problems with dropped calls on the WLAN.
                          What is a common cause of dropped calls when using Wi-Fi VoIP phones?

                          A. Data rates below 54 Mbps
                          B. Slow roaming
                          C. Use of WMM
                          D. Data rates below 75 Mbps


                          Question #3
                          As the WLAN administrator in your organization you are responsible for troubleshooting connection issues. Several STAs are connecting to the network, but are unable to communicate after connection. You suspect a DHCP problem. After capturing traffic on the wired-side of the AP, you want to view only DHCP traffic.
                          What filter in Wireshark can be used for this purpose?

                          A. DHCPv4
                          B. BOOTP
                          C. DHCP
                          D. DHCPv6


                          Question #4
                          To what data rates can a 5 GHz PHY device shift when changers occur in the signal strength?

                          A. 11, 5.5, 2, 1
                          B. 24, 18, 11, 2
                          C. 24, 18, 12, 5.5
                          D. 24, 18, 12, 6


                          Question #5
                          You work as an SE for a value-added reseller. A client has an existing deployment of
                          802.11n Aps and wants to upgrade several BSSs to 802.11ac.
                          What hardware feature of some enterprise Aps may allow for this without a forklift upgrade?

                          A. Simply check the Enable 802.11ac checkbox in the web-based configuration interface
                          B. Converting the 802.11n radio to an 802.11ac radio through software
                          C. Replace the antennas with 802.11ac antennas
                          D. Adding an 802.11ac module to the existing APs
