A customer reports that their laptop frequently disconnects from the office Wi-Fi and reconnects after a few seconds. The network uses WPA2-PSK with AES encryption. The technician checks the router logs and sees repeated '4-way handshake timeout' errors. What is the most likely cause of this issue?

A user reports that their smartphone cannot connect to the office Wi-Fi, but other devices can. The network uses WPA2-Enterprise with PEAP-MSCHAPv2. The technician checks the phone's settings and sees that it is configured for WPA2-PSK. What is the most likely reason for the connection failure?

A security incident occurs where an attacker captures the 4-way handshake of a WPA2-PSK network and successfully cracks the passphrase offline. The technician is tasked with preventing this type of attack in the future. Which protocol should the technician implement?

A technician is setting up a wireless network for a home office. The client is concerned about neighbors accessing their internet. The technician enables WPA2-PSK with a strong passphrase. Which additional step should the technician take to ensure the network is as secure as possible?

During a security audit, a technician discovers that a company's wireless network uses WEP encryption. The network has been in place for 10 years and still uses the original router. What is the most immediate security risk?

A technician is configuring a wireless network for a new office. The network must support legacy devices that only support WPA-TKIP, but the technician also wants to maximize security for modern devices. Which configuration should the technician use?

A technician is troubleshooting a wireless network where users report intermittent connectivity. The network uses WPA2-Enterprise with a RADIUS server. The technician notices that the RADIUS server logs show frequent authentication failures from one specific access point. What is the most likely cause?

A small business owner wants to replace their old wireless router because guests have been using the network to access inappropriate content. The owner wants to isolate guest traffic from the main business network and enforce content filtering. Which combination of wireless security and features should the technician recommend?

During a wireless site survey, a technician discovers that an employee has set up a personal wireless router in their cubicle, connected to the corporate network. This rogue access point is broadcasting an open SSID. Which security risk is most immediately concerning?

A technician is setting up a guest Wi-Fi network in a coffee shop. The owner wants customers to be able to connect easily without entering a password, but still wants basic encryption to prevent eavesdropping. Which security configuration should the technician use?

A company's IT policy requires that all wireless connections use certificate-based authentication to prevent unauthorized access. The network is currently using WPA2-PSK. Which configuration change is necessary to meet this policy?

A user's laptop running Windows 10 Pro connects to the corporate Wi-Fi but cannot access internal resources. The network uses WPA2-Enterprise with PEAP-MSCHAPv2. The laptop's wireless profile is configured correctly. Other users in the same office can access resources. What is the most likely cause?

A small business owner reports that after upgrading their wireless router to a newer model, their older laptops running Windows 7 cannot connect to the Wi-Fi network. The new router is configured with WPA3-Personal. Which of the following is the most likely reason for the connectivity failure?

A network administrator is configuring a new wireless network for a hospital that requires the highest level of security for patient data. The network must support 802.1X authentication with smart cards. Which combination of security protocols and authentication methods should be used?

A customer calls saying their home Wi-Fi network suddenly stopped working after they changed the router's security mode from WPA2-PSK to WPA2-Enterprise. All their devices previously connected fine. What is the most likely cause of the problem?

During a security audit at a law firm, the IT manager wants to ensure that all wireless communication is encrypted with the strongest available standard that is also compatible with their mix of Windows 10 laptops and iOS tablets. Which security protocol should you recommend?

A company's security policy mandates that all wireless traffic must be encrypted using a protocol that is resistant to KRACK attacks. The current network uses WPA2-PSK with AES. Which of the following upgrades should be implemented to meet this requirement?

A user reports that their Windows 11 laptop can see the office Wi-Fi network but fails to connect, displaying 'Can't connect to this network'. Other users with the same laptop model connect without issues. The network uses WPA2-PSK with AES. What should you check first?

A user reports that their corporate laptop can connect to the guest Wi-Fi network but not to the internal corporate network. Both networks use WPA2-Enterprise with 802.1X. The laptop works fine on other corporate networks. What is the most likely issue?

A customer complains that their new smartphone connects to their home Wi-Fi but has no internet access. The router is configured with WPA2-PSK and a 64-character pre-shared key. Other devices work fine. What is the most likely cause?

A technician is troubleshooting a wireless network where users report intermittent connectivity and slow speeds. The network uses WPA2-Enterprise with EAP-TLS and certificate-based authentication. The technician notices that the RADIUS server logs show frequent certificate validation failures. What is the most likely root cause?

A company's security policy requires all wireless traffic to be encrypted with AES. A technician is configuring a new access point and sees the following options: WPA2-PSK (TKIP), WPA2-PSK (AES), WPA3-SAE, and WEP. Which option should the technician select?

During a security audit, a technician discovers that a small office's wireless router is still using WPA-TKIP. The office has 20 devices, including some older smartphones that cannot support WPA2. What should the technician recommend to improve security without replacing all devices?

A technician is setting up a wireless network for a small office that handles sensitive client data. The office has a mix of modern laptops and a few legacy printers that only support WEP. What should the technician do to maintain security while keeping the printers functional?

A network administrator is investigating a security incident where an attacker captured the 4-way handshake of a WPA2-PSK network and successfully cracked the passphrase. Which protocol change would most effectively prevent this type of attack in the future?

A technician is configuring a new wireless network for a school. The network must support hundreds of student devices simultaneously and provide strong security. The school wants to use a single SSID with individual logins for students. Which security protocol should the technician choose?

A small business owner reports that after upgrading their wireless router to a newer model, several older laptops running Windows 7 can no longer connect to the Wi-Fi network. The new router is configured to use WPA3. What is the most likely reason for the connection failures?

A user reports that their laptop frequently disconnects from the office Wi-Fi and reconnects after a few seconds. The network uses WPA2-Enterprise with PEAP-MSCHAPv2. Other users do not experience this issue. What is the most likely cause?
