WGU D325 Lesson 12 ACTUAL TEST||KEY EXAM QUESTIONS WITH CORRECT VERIFIED SOLUTIONS||A+ GRADED!!!UPDATED 1) What is the purpose of using a VPN with an open Wi-Fi network? - ANSWER To create an encrypted tunnel for secure communication 2) What mechanism does WPA3 use to encrypt open authentication traffic? - ANSWER Wi-Fi Enhanced Open 3) What is an enterprise mobility management (EMM) suite primarily used for in a BYOD environment? - ANSWER To enforce security policies on connected devices 4) What is one solution to mitigate the risk of rogue access points? - ANSWER Using EAP-TLS security for mutual authentication 5) Which of the following BEST describes the method an attacker might use to make an evil twin access point more appealing to unsuspecting users? - ANSWER Configuring the evil twin access point with a similar or identical SSID to a legitimate access point 6) What is the inverse-square rule in the context of wireless signals? - ANSWER Doubling the distance between devices reduces the signal strength by a factor of four 7) What can cause a loss of power/signal strength in a wireless network? - ANSWER Free space path loss and interference 8) What is throughput in the context of wireless networks? - ANSWER The amount of data transferred at the network layer 9) What is the recommended AP power setting relative to the weakest client power? - ANSWER 2/3rds of the weakest client power 10) What is antenna cable attenuation? - ANSWER The loss of signal strength along a coax cable 11) Why is it important to consider the band (2.4 GHz or 5 GHz) that client devices support when addressing wireless coverage issues? - ANSWER Client devices that only support 2.4 GHz cannot connect to a 5 GHz network. 12) In a complex environment, why might it be necessary to adjust the power level used by an access point on a given channel? (Select two.) - ANSWER To ensure clients can communicate effectively To prevent the access point from interfering with other cells 13) What type of interference occurs when access points are configured to use overlapping channels, such as channels 1 and 3 in the 2.4 GHz band? - ANSWER Adjacent channel interference 14) Aside from interference, what could signal problems also be a result of? - ANSWER An attack on the network by making clients connect to a rogue AP 15) What is Electromagnetic Interference (EMI) and how can it be detected? - ANSWER EMI is interference from a powerful source in the same frequency band. 16) What is the primary purpose of analyzing access point association times for client devices? - ANSWER To identify issues with roaming 17) What is a legitimate reason for a client to disassociate but not de authenticate from an AP? - ANSWER The client is roaming in an extended service area. 18) What might unexpected client disassociations indicate if there is no roaming, interference, or standards support issue? - ANSWER A potential malicious attack 19) What role does a controller play in managing overcapacity in an enterprise Wi-Fi solution? - ANSWER It provides reporting tools to diagnose bandwidth issues. 20) What is a common method to dynamically manage network load and reduce overutilization in a wireless network facing overcapacity issues? - ANSWER Reassigning wireless channels dynamically 21) During a company-wide meeting, it was observed that the Wi-Fi network became significantly slower, and some attendees could not connect to the network at all. The meeting room is equipped with a single AP designed to support up to 30 clients, but there were 50 attendees, most of whom were trying to connect their devices to the Wi-Fi network. 22) Which of the following solutions would be MOST effective in preventing such overcapacity issues in future meetings? - ANSWER Install an additional AP in the meeting room. 23) What is the recommended maximum channel utilization to minimize co-channel interference? - ANSWER 50% 24) What does a negative dBm value represent? - ANSWER A fraction of a milliwatt 25) What is the typical round trip time (RTT) delay when accessing a site over a satellite link compared to DSL? - ANSWER 600-800 ms for satellite and 10-20 ms for DSL 26) What issue can arise with captive portals? - ANSWER Redirects may not work if the portal does not use HTTPS. 27) A network administrator is tasked with enhancing the security of their company's wireless network. The company has been using WPA2-Personal for wireless security, but with the growing number of employees and the need for individual accountability, the administrator decides to switch to an enterprise authentication method. The network administrator configures the access points to use WPA2-Enterprise with an AAA server for authentication. 28) Which of the following BEST describes the benefit of the network administrator's decision to switch to WPA2-Enterprise? - ANSWER It enables individual user authentication and accountability.
