FAQ
Hardware requirements?
A laptop with 16GB RAM and local SSD is recommended. Labs stream from our sandbox; you do not need a GPU.
Can teams attend together?
Yes, with a shared workbook. Individual accountability checkpoints remain per learner.
Is cross-region replication included?
We touch distributed availability groups at a planning depth only; building them across clouds is not included.
Experience notes
The quorum worksheet alone paid for the course. The readable routing lab assumed a cleaner network than ours, so I had to adapt, which the instructor encouraged.
