Program narrative
This track sequences guided labs that mirror day-two operations for production clusters in Seoul-region data halls. You rehearse patching cadences, observe wait statistics, and document change windows using our rubric so the scope stays clear when you sit the exam.
Included rehearsals
- Scenario labs for availability groups and readable secondaries
- Query store snapshots with annotated review notes
- Operational runbooks for index maintenance and fragmentation
- Tempdb layout drills with measurable IO patterns
- Extended events templates tuned for OLTP noise
- Post-lab reflection prompts mapped to blueprint domains
- Peer review checklist for change approvals
Outcomes you can evidence
- Produce a defensible maintenance calendar for clustered instances
- Explain tempdb contention using captured wait types
- Assemble an incident packet with timelines and remediation steps

FAQ
Do you include official exam vouchers?
No. Pricing covers instruction, labs, and mock attempts. You purchase vouchers directly from the provider when you are ready.
What if I fall behind during a release week at work?
You can shift one clinic sitting per month. We do not promise unlimited extensions because pacing integrity matters for the group.
Is performance tuning covered end-to-end?
We cover the administrator-facing surface area required by the blueprint. Deep developer tuning is out of scope and called out explicitly in week four.
Experience notes
Week two’s lab on patching failover pairs finally made the checklist feel repeatable. I still wish the module on readable routing had one more drill, yet the mentor notes on my submission were precise.
The tempdb layout exercise referenced the same NUMA sketch our team argues about—useful, not theatrical.
