SUSE Linux Advanced System Administration (SCA) Course Overview This instructor led SUSE Linux Advanced System Administration (SCA) training course is designed to teach the advanced administration,security,networking and performance tasks required on a SUSE Linux Enterprise system. Similarly,the course is targeted to closely follow the official SUSE Certified Administrator curriculum for certification. Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.
TARGET AUDIENCE:
Who will the Course Benefit? The SUSE Linux Advanced System Administration (SCA) training course is suitable for Linux System Administrators who need to acquire advanced administration knowledge of the key administrative,networking and security tasks required on Linux within the Enterprise. An ideal course for delegates who will be working in an environment using several different Linux distributions and therefore knowledge of skills common to all the different Linux distributions is required. For the purpose of practical exercises,SUSE Linux will be used. Note: Should the delegate only require knowledge of Red Hat Linux then they should instead consider attending our range of Red Hat Linux Administration courses.
COURSE PREREQUISITES:
Requirements Experience of administering Linux in an Enterprise environment to the level covered in the SUSE Linux System Administration (SCA) course.
