Lab Assessment Questions & Answers

Instead of assigning permissions to a new user every time someone is hired, you would just add them to the groups they need. 2.Given a scenario where there are five (5) database administrators that may periodically need access to a given system. Discuss a concept to better manage these administrators' access permissions. You would add the 5 dba’s to group that would be assigned access to the system. 3.The new web administrator's account has been set up and a password provided. What is the process to force a password change upon first login?

You should type “su –c ‘ change –d 0 (users name)” 4.What is the purpose of the “su” command? Explain its significance.
