While troubleshooting a computer problem, a technician has determined what has caused the problem. Which of the following should be the technicians NEXT troubleshooting step?
-
Document findings, actions and outcomes.
-
Ask the user opened ended questions to see if they agree with the cause.
-
Establish a plan of action and implement the solution.
-
Verify full system functionality.
Correct Answer
A. Establish a plan of action and implement the solution.Explanation
The technician's next troubleshooting step should be to establish a plan of action and implement the solution. This is because once the cause of the problem has been determined, the technician needs to come up with a plan to fix it and then take action to implement that plan. Documenting findings, actions, and outcomes should be done throughout the troubleshooting process, but it is not the next step after determining the cause. Asking the user open-ended questions to confirm the cause may be helpful, but it is not the next step in the troubleshooting process. Verifying full system functionality should be done after the solution has been implemented.Rate this question:

Which of the following are forms of biometric authentication? (Select THREE).
-
Smart card
-
Barcode scanner
-
Voice recognition
-
Fingerprint reader
-
Optical recognition
-
Secure ID Token
Correct Answer(s)
A. Voice recognition
A. Fingerprint reader
A. Optical recognitionExplanation
The correct answer is Voice recognition, Fingerprint reader, and Optical recognition. These three options are forms of biometric authentication because they rely on unique physical characteristics of an individual. Voice recognition analyzes the unique features of a person's voice, fingerprint reader scans and matches the patterns on an individual's fingerprint, and optical recognition uses technology to analyze and match the unique patterns of an individual's iris or retina. Smart card, barcode scanner, and secure ID token are not forms of biometric authentication as they do not rely on unique physical characteristics of an individual.Rate this question:

If a computer needs Windows XP and Windows 2000 configured for a dual-boot environment, which of the following file system should be used in formatting the drive?
-
NTFS
-
UFS
-
FAT
-
NFS
Correct Answer
A. NTFSExplanation
To configure a dual-boot environment with Windows XP and Windows 2000, the NTFS file system should be used in formatting the drive. NTFS (New Technology File System) is the preferred file system for Windows operating systems as it offers better security, reliability, and support for larger file sizes and volumes compared to FAT (File Allocation Table) file system. UFS (Unix File System) and NFS (Network File System) are not compatible with Windows operating systems and therefore not suitable for this scenario.Rate this question:
