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?

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? Select one: Back up the user data to a removable drive. Perform file restore from the existing backup copy at the logical partition. Run the CHKDSK utility. Install a new hard disk as the primary disk, then make the current disk a slave.

Back up the user data to a removable drive. 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.

A scientific expedition team is using laptops for their work. The temperatures where the scientists are working range from -13 degrees Fahrenheit (-25 degree Celsius) to 80 degrees Fahrenheit (27 degrees Celsius). The humidity level is around 40 percent. Noise levels are low, but the terrain is rough and winds can reach 45 miles per hour (72 kilometers per hour). When needed, the scientists stop walking and enter the data using the laptop. Which condition is most likely to adversely affect a laptop that is used in this environment?

the temperature Even though laptops are normally manufactured to operate within a wide range of temperatures, the lower temperature is below freezing and not an optimal environment.
