A user reports that the pages flash on the screen two or three times before finally staying open when attempting to access banking web pages. Which of the following troubleshooting steps should the technician perform NEXT to resolve the issue?
Correct Answer:
B
The next troubleshooting step that the technician should perform to resolve the issue of pages flashing on the screen before staying open when accessing banking web pages is to verify the address bar URL. The address bar URL is the web address that appears in the browser’s address bar and indicates the location of the web page being accessed. Verifying the address bar URL can help determine if the user is accessing a legitimate or malicious website, as some phishing websites may try to impersonate banking websites by using similar-looking URLs or domains.
A hard drive that previously contained PI I needs to be repurposed for a public access workstation. Which of the following data destruction methods should a technician use to ensure data is completely removed from the hard drive?
Correct Answer:
A
Shredding is a data destruction method that physically destroys the hard drive by cutting it into small pieces using a machine. Shredding ensures that data is completely removed from the hard drive and cannot be recovered by any means. Shredding is suitable for hard drives that contain PII (personally identifiable information),
which is any information that can be used to identify, contact, or locate an individual. Degaussing, low-level formatting, and recycling are not data destruction methods that can guarantee complete data removal from a hard drive.
Which of the following would most likely be used to extend the life of a device?
Correct Answer:
C
Proper ventilation is a factor that can extend the life of a device by preventing overheating and thermal damage to the device’s components. Proper ventilation means ensuring that there is enough airflow around and inside the device to dissipate heat and maintain a suitable temperature for optimal performance. Proper ventilation can be achieved by using fans, heat sinks, vents, or liquid cooling systems, as well as avoiding placing the device near heat sources or in enclosed spaces. Battery backup, electrostatic discharge mat, and green disposal are not factors that can extend the life of a device.
A technician removed a virus from a user's device. The user returned the device a week later with the same virus on it. Which of the following should the technician do to prevent future infections?
Correct Answer:
B
Educating the end user is the best way to prevent future infections by viruses or other malware. The technician should teach the user how to avoid risky behaviors, suchas opening suspicious attachments, clicking on unknown links, downloading untrusted software, etc. Disabling System Restore, installing the latest OS patches and performing a clean installation are possible ways to remove existing infections, but they do not prevent future ones.

Which of the following could be used to implement secure physical access to a data center?
Correct Answer:
C
Badge readers are used to implement secure physical access to a data center. They are used to read the identification information on an employee’s badge and grant access to the data center if the employee is authorized2.
This system requires individuals to have an access badge that contains their identification information or a unique code that can be scanned by a reader. After the badge is scanned, the system compares the information on the badge with the authorized personnel database to authenticate if the individual has the required clearance to enter that area. The other options listed, such as a geofence, alarm system, or motion sensor are security measures that may be used in conjunction with badge readers, but do not provide identification and authentication features.
