An employee mentions that opening a large document file is taking longer than usual. The desktop support technician suspects that there might be a fault in the hard disk. What should the technician do next?
Always perform a backup before beginning any troubleshooting. The correct answer is: Back up the user data from the workstation.
A customer reports that recently several files cannot be accessed. The service technician decides to check the hard disk status and the file system structure. The technician asks the customer if a backup has been performed on the disk and the customer replies that the backup was done a week ago to a different logical partition on the disk. What should the technician do before performing diagnostic procedures on the disk?
Always perform a backup before beginning any troubleshooting. Even though the data was backed up to a different partition, the data is still on the same hard drive. If the drive crashes, the data might not be recoverable. The correct answer is: Back up the user data to a removable drive.
What task should be completed before escalating a problem to a higher-level technician?
Before escalating a ticket, document each test that has been performed. Information about the tests is vital if the problem needs to be escalated to another technician. The correct answer is: Document each test that was tried.
A company is deploying both thin and thick client computers. Which configuration step will a technician need to do on the thin clients that will most likely not be done on the thick clients?
Connect the computer to the application server. A thick client is a normal corporate workstation.
