SQL 2016 ALWAYSON HIGH AVAILABILITY (55246-A)
This three-day instructor-led training is aimed to familiarize database administrators and Windows engineers with SQL Always On and High Availability principles. It compares and contrasts SQL 2012 and SQL 2014. This SQL online course is a lab intense course to give students a strong grip on the SQL. Being an advance SQL course only experienced DBAs and windows server pros can take advantage of it.
Audience profile
Experienced DBAs, Windows Server pros, team leads. This is a lab intense course! 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. We did this because it is common in technical courses to write long labs with multiple exercises which in our opinion is not effective as they turn into ?click streams?. We assume the student is new to the technology and that the instructor is knowledgeable in it.
