HP-UX System and Network Administration for Experienced UNIX System Administrators (H5875S) is fast-paced and ONLY covers the differences between HP-UX and other versions of UNIX. Potential students must already be experienced in the administration of another version of UNIX to get the full benefit from this course.
The following questions are a guide to help you check your existing UNIX administration knowledge and experience. If you score less than 22 correct answers, HP Education & Training strongly recommends that you consider taking the following course and course bundle instead:
- HP-UX System and Network Administration I (H3064S)
followed by
- HP-UX System and Network Administration II (H3065S)
