The interviewer will ask this question to again test your knowledge of the software and try to determine how long you've been working with it. Knowing about this will demonstrate your expertise and convince them that you're able to work with older versions of SCOM and, if necessary, upgrade older versions they may already have.
"SCOM was originally developed by Serverware Group and was known as SeNTry ELM. A company by the name of Mission Critical Software acquired the rights to this back in the nineties and changed the name of the product to OnePoint Operations Manager. Microsoft acquired the product in 2001 and renamed it Microsoft Operations Manager, or MOM. MOM was very similar to SCOM 2019, except for the number of Service Packs available. In 2007, Microsoft renamed the product to SCOM 2007 and included several new features in this new release. There were two updates to SCOM and 2012, and another in 2016. The product was most recently updated in 2019."
"SCOM originated as SeNTry ELM from a company called Serverware Group plc. Mission Critical Software acquired the rights in 1998, adapted it, and changed the name to OnePoint Operations Manager. Mission Critical Software merged with NetIQ and sold the rights to Microsoft in 2000. They renamed the product to Microsoft Operations Manager (MOM) and released it in 2001. MOM worked in concert with two other Microsoft programs: Systems Management Server (SMS) 2.0 and Application Center 2000. Microsoft released MOM 2005 Service Pack 1 in 2005 with several enhancements, including mutual authentication, agent proxy capabilities, a secure communications channel, and secure credential storage. In 2007, Microsoft renamed MOM to System Center Operations Manager (SCOM). The company added the command shell to this update. In 2012, Microsoft released System Center 2012 and introduced high availability, application performance monitoring, dashboards, and network device monitoring. Microsoft released System Center 2016 with more advanced cross-platform infrastructure and workload monitoring, further integrating SCOM with the rest of System Center. SCOM 2019 was released in March and focused on areas of monitoring, such as adding tools for monitoring and managing data centers, adding support and management capabilities to newer versions of Windows server, and enabling hybrid management and monitoring with Azure."
