Which of the following authentication methods is token-based?
A. Kerberos
B. TACACS+
C. Passwords
D. TKIP
Show Answer
Correct Answer: A
Explanation: Kerberos uses ticket-based authentication. After initial authentication, it issues tickets (such as a Ticket Granting Ticket and service tickets) that act as authentication tokens to prove identity without repeatedly sending passwords. The other options are not token-based authentication methods.
Question 41
The battery on a user’s smartphone discharges quickly when the user travels. The smartphone was replaced two weeks ago. Which of the following should a technician do first?
A. Replace the battery with a higher capacity option.
B. Provide an external battery to extend the usage time.
C. Ensure that the charging port is working as expected.
D. Look for applications that are reporting the highest utilization.
Show Answer
Correct Answer: D
Explanation: Because the phone was replaced recently, a failing battery or hardware issue is unlikely. Rapid discharge while traveling commonly results from apps using GPS, background data, or roaming services. The first troubleshooting step is to review battery usage and identify high-utilization applications before considering hardware replacements or accessories.
Question 42
After using a third-party disk optimization software package, a technician restarts a laptop and receives the message No operating system found. The technician verifies that the BIOS properly recognizes the SSD. Which of the following should the technician do next?
A. Update BitLocker settings in the BIOS.
B. Replace the CMOS battery.
C. Turn on from installation media and repair the MBR
D. Isolate the system from the corporate network.
Show Answer
Correct Answer: C
Explanation: The BIOS recognizes the SSD, so the hardware is functioning. The error "No operating system found" commonly indicates a corrupted or missing boot loader/MBR, which can occur after disk optimization tools modify disk structures. Booting from installation media and repairing the MBR or boot records is the appropriate next step. The other options do not address a boot record corruption scenario.
Question 43
Various alerts on a user’s Windows 11 laptop are continually interrupting the user during videoconference calls. Which of the following should a support technician recommend to best solve the issue?
A. Use multiple sound output devices for the various source applications.
B. Disable all notifications in different applications in the order they appear.
C. Configure the Sounds option in Control Panel to be set to No Sounds.
D. Set Windows Notifications settings to Do Not Disturb.
Show Answer
Correct Answer: D
Explanation: Windows 11’s Do Not Disturb mode suppresses notification alerts during meetings without disabling system sounds or requiring per-application changes, making it the most effective and least disruptive solution for interruptions during videoconference calls.
Question 44
A customer is explaining issues with a workstation to a technician. While the customer is listing the issues, the technician is browsing social media on a smartphone. Which of the following professionalism and communication techniques should the technician be using in this situation? (Choose two.)
A. Follow up with the customer.
B. Avoid personal interruptions.
C. Provide proper documentation.
D. Clarify customer statements.
E. Actively listen and take notes.
F. Maintain professional attire.
Show Answer
Correct Answer: B, E
Explanation: The technician should demonstrate professionalism by avoiding personal interruptions such as browsing social media while the customer is speaking. In addition, actively listening and taking notes ensures the technician fully understands the issues being described and shows respect and engagement with the customer.
Question 45
A customer reports that a computer is displaying pop-ups and making unexpected sounds. Which of the following should a technician do before remediating this issue?
A. Back up the customer's data.
B. Update the OS.
C. Reimage the workstation.
D. Quarantine the machine.
Show Answer
Correct Answer: D
Explanation: The symptoms described (pop-ups and unexpected sounds) strongly suggest malware infection. Before attempting any remediation, a technician should quarantine/isolate the machine from the network to prevent the potential spread of malware to other systems. Actions like updating the OS or reimaging come later, and while backing up data is important, it should not be done until the system is isolated to avoid spreading the infection.
Question 46
A Microsoft OS laptop user requests an alternative log-in authentication method because they have forgotten their password multiple times. Which of the following should a technician enable to satisfy this request?
A. Single sign-on
B. Windows Hello
C. BitLocker
D. User Account Control
Show Answer
Correct Answer: B
Explanation: Windows Hello provides alternative authentication methods such as biometric (fingerprint, facial recognition) or PIN-based sign-in, allowing users to log in without repeatedly entering a traditional password. The other options do not replace or simplify the Windows log-in authentication process.
Question 47
A user’s computer is running slowly. Web pages take several seconds to open, and applications are slow responding to user input. A technician opens the Windows Task Manager and sees the following information:
Disk: 2%
Network: 12%
GPU: 15%
CPU: 70%
Memory: 97%
Which of the following would a technician most likely do to resolve the issue?
A. Clear browser cached data.
B. Upgrade the network connection.
C. Close unnecessary programs.
D. Delete temporary files.
Show Answer
Correct Answer: C
Explanation: The Task Manager shows memory usage at 97%, which commonly causes system-wide slowness as the system relies heavily on paging. Closing unnecessary programs reduces memory consumption immediately. Network, disk, and GPU usage are low, and clearing cache or temporary files would not address acute high memory usage.
Question 48
Which of the following malware types typically has very high computing resource usage?
A. Rootkit
B. Cryptominer
C. Boot sector virus
D. Trojan
Show Answer
Correct Answer: B
Explanation: Cryptominers are designed to perform continuous, intensive cryptographic calculations to mine cryptocurrency, which leads to sustained high CPU/GPU usage. The other malware types focus on persistence, stealth, or unauthorized access rather than heavy computation.
Question 49
Which of the following is a protocol that provides AAA for network services?
A. RADIUS
B. Kerberos
C. TKIP
D. WPA3
Show Answer
Correct Answer: A
Explanation: RADIUS is specifically designed to provide centralized Authentication, Authorization, and Accounting (AAA) for network access. Kerberos handles authentication only, while TKIP and WPA3 are wireless security mechanisms rather than AAA protocols.
