Audience Profile

Experienced DBAs, Windows Server pros, team leads.

We designed this course based on our experience of having taught hundreds of classes to literally thousands of students. We tried very hard to make the labs, of which there are over 30, very oriented to a single concept such as Adding a Replica or Transferring Logons. 

Q: What is SQL Always On high availability?

A: The SQL is always in high availability and features a disaster-recovery solution that provides an enterprise-level option for database mirroring. Introduced in SQL Server 2012 (11. x), Always On availability groups maximize the availability of a group of user databases for a business.

Q: What are the duration and prerequisites of the 55246-A: SQL 2016 Always on High Availability course?

A: The duration of this course is 3 days, whereas before this course, learners must have experience in SQL DBA and Windows IT Pro.

Q: What is the course objective of the 55246-A: SQL 2016 Always on High Availability course?
