SCA+ in SUSE Linux Enterprise High Availability

PLEASE NOTE: This exam will be retired on 30 April, 2024

The  SCA+ in SUSE Linux Enterprise High Availability certification is an additional option focused on High Availability technologies for administrators who already have an SCA in SLES and are working with the SUSE Linux Enterprise High Availability Extension. Obtaining this certification proves that you understand the details of how to implement and manage an HA solution using the SLES HA Extension. 

How to Earn the Certification

In addition to the core SCA+ in SUSE Linux Enterprise High Availability exam, the SCA or SCE in SUSE Linux Enterprise Server version 12 or 15 certification is a prerequisite for this SCA+ certification.

You will receive the corresponding 12 and/or 15 version of the SCA+ in SUSE Linux Enterprise HA depending on the prerequisite certification you have earned.  You will be awarded the SCA+ in SUSE Linux Enterprise High Availability 15 if you pass the core exam and also hold an SCA in SUSE Linux Enterprise Server 15 OR SCE in SUSE Linux Enterprise Server 15. You will be awarded the SCA+ in SUSE Linux Enterprise High Availability 12 if you pass the core exam and also hold an SCA in SUSE Linux Enterprise Server 12 OR SCE in SUSE Linux Enterprise Server 12.

Important Note: This exam will be retired on 30 April 2024. It will be replaced by the new SCE in SUSE Linux Enterprise 15 High Availability.
