Source-QA discrepancy resolved for GitHub conversion
The Drive Practice tab contains DS6-001 through DS6-056; the Answer Key has the same 56 IDs; the Coverage tab reports 56 and 14 answers in each position. The Instructions tab retains stale cells saying 72 and 18 A · 18 B · 18 C · 18 D. This GitHub conversion follows the populated bank and Coverage tab: 56 / 14 each.
Diagnostic tags to record after real misses
Useful confusion-pair tags include: - Storage & Operations vs adjacent Knowledge Areas; - database vs instance vs schema vs node; - administrator-role confusion; - centralized vs distributed vs federated; - loose vs tight federation; - ACID vs BASE vs CAP; - Production vs Development vs Test vs Sandbox; - relational/schema-on-write vs non-relational/schema-on-read; - row vs column orientation; - valid vs transaction time; - retention vs archive vs purge; - CDC vs replication vs sharding; - active vs passive replication; - mirroring vs log shipping; - resiliency vs recovery; - backup vs tested recovery; - physical vs functional configuration audit; - availability vs speed; - migration vs integration; - Storage vs Performance vs Operational vs Service metrics; - Data Audit vs Data Validation.
