An Internet cafe has several computers available for public use. Recently, users have reported the computers are much slower than they were the previous week. A technician finds the CPU is at 100% utilization, and antivirus scans report no current infection. Which of the following is MOST likely causing the issue?

B. A cryptominer is verifying transactions.
C. Files were damaged from a cleaned virus infection.
D. A keylogger is capturing user passwords.
Correct Answer: B
A cryptominer is a malicious program that uses the CPU resources of a computer to generate cryptocurrency, such as Bitcoin or Ethereum. This can cause the CPU to run at 100% utilization and slow down the system. Spyware, virus and keylogger are other types of malware, but they do not necessarily cause high CPU usage.

Question 553:
Which of the following is an advantage of using WPA2 instead of WPA3?
A. Connection security
B. Encryption key length
C. Device compatibility
D. Offline decryption resistance
Correct Answer: C
Device compatibility is an advantage of using WPA2 instead of WPA3. WPA2 is the previous version of the Wi-Fi Protected Access protocol, which provides security and encryption for wireless networks. WPA3 is the latest version, which offers improved security features, such as stronger encryption, enhanced protection against brute-force attacks, and easier configuration. However, WPA3 is not backward compatible with older devices that only support WPA2 or earlier protocols. Therefore, using WPA3 may limit the range of devices that can connect to the wireless network. Connection security, encryption key length, and offline decryption resistance are advantages of using WPA3 instead of WPA2.

Question 554:
A user opened a ticket regarding a corporate-managed mobile device. The assigned technician notices the OS Is several versions out of date. The user Is unaware the OS version is not current because auto- update is turned on. Which of the following is MOST likely the cause of the Issue?
A. The device does not have enough free space lo download the OS updates.
B. The device needs domain administrator confirmation to update to a major release.
C. The device is not compatible with the newest version of the OS.
D. The device is restricted from updating due to a corporate security policy.
Correct Answer: D
A corporate security policy can restrict a corporate-managed mobile device from updating its OS automatically, even if the auto-update feature is turned on. This can be done to prevent compatibility issues, security risks or performance problems caused by untested or unwanted updates. The device administrator can control when and how the updates are applied to the device. The device not having enough free space, needing domain administrator confirmation or being incompatible with the newest version of the OS are not likely causes of the issue, since the user would receive an error message or a notification in those cases.

A. Do not notify the customer if arriving before the customer.
B. Dismiss the customer and proceed with the after-hours work.
C. Contact the customer if the technician is arriving late.
D. Disclose the experience via social media.
Correct Answer: C
The best option for the technician to demonstrate proper communication techniques and professionalism is to contact the customer if the technician is arriving late. This shows respect for the customer's time and expectations, and allows the customer to adjust their schedule accordingly. It also helps to maintain a positive relationship and trust between the technician and the customer. The technician should apologize for the delay and provide a realistic estimate of their arrival time. The technician should also thank the customer for their patience and understanding. The other options are not appropriate or professional. Do not notify the customer if arriving before the customer is not a good practice, as it may cause confusion or frustration for the customer. The customer may have made other plans or arrangements based on the technician's original schedule, and may not be available or prepared for the service. Dismiss the customer and proceed with the after-hours work is rude and disrespectful, as it ignores the customer's needs and preferences. The customer may have questions or concerns about the service, or may want to supervise or verify the work. The technician should always communicate with the customer before, during, and after the service. Disclose the experience via social media is unethical and unprofessional, as it may violate the customer's privacy and the company's policies. The technician should not share any confidential or sensitive information about the customer or the service on social media, or make any negative or inappropriate comments about the customer or the situation.
