Hi! I am studying for a complex exam from networking, database administration. project management, system analysis, SDLC and programming and I have some networking questions I need help with. I am working as a computer tech and I need to confirm my knowledge. Any help will be appreciated.
Here they are:
1) How should you help users who have forgotten their user account
passwords?
A.

3) You are consulting a company with a LAN application that is not
performing as expected. Your analysis shows that the application transfers
large amounts of data to and from a database server over the network and
needs near real-time response.

expected? (Choose three.)
A.
fiber channel RAID
B.
database server fail over
C.
