Define a retinal projection display. GPS Stands for: What is E-ink and how does it work? What is a hardware 2FA token? Name a currently available product. Ransomware damage can be limited by frequent and regular use of: Define Tailgating. Give an example of a physical device that can help prevent tailgating. List the top 3 mobile operating systems by market share in Jan 2021: List 2 advantages and 2 disadvantages to mobile device tethering. List in order the 6 steps to take in troubleshooting computers. What is a rootkit and why are they (good/bad)? . What are the four general areas of safety with regard to PC's? . You have a user whose PC is completely hung. They report it had been making a slight grinding noise, intermittently for weeks and before the hang it was exceptionally hot. You ask what happens when they reboot and they report the same issue. But, if they leave it long enough, it will work again for a little bit and hang again. What are some things you can check and what is the likely cause? You have a user who reports their computer is randomly crashing. They notice it only seems to happen when they have several applications open. What is the likely hardware problem and how could you test this? 14. Your PC has been booting from a USB flash for a year. But, all of a sudden you receive a message that there's "no bootable device". You test the USB flash and it's still working. You check the boot order in the bios and it's changed!

Which RAID type might you use to fulfill these requirements? 19. You are an administrator who must deploy a database server. The databases will be very transactional and therefore require high write and read speed. What attributes might you consider when choosing your drive? 20. Which optical storage type can store the most and how? 21. Which RAID gives you full failover and the highest throughput? 22. How can you copy a file from one directory to another, using the command prompt? 23. You must run a backup of a very important directory on the hard drive of a server, every night. What utility (builtin Windows) could you use to make sure this task runs every night? Define a retinal projection display. GPS Stands for: What is E-ink and how does it work?
