Fact verification pass, 2026-11-07¶

A claim-by-claim check of the pages written on 2026-11-07 against vendor and project primary documentation fetched the same day. Skipped: README and index pages, generated files, docs/content-gaps-2026-11-07.md, and the exams/snowflake and exams/mongodb notes (already corrected). Counts are approximate groupings of checkable claims (product behavior, defaults, names, flags, versions), not a line-exact audit.

Classes. VERIFIED: the fetched page supports it. FIXED: the page said something the source contradicts or does not support, now changed. UNVERIFIABLE: no fetched source settles it; the page now says so, or the claim was softened or removed.

Per page¶

Hands-on and day-one pages were run for real on 2026-11-07; only their vendor claims (versions, defaults, flags) were checked here, not the pasted outputs. The Dagster "open source" wording is counted under the ETL page.

Fixes¶

Still unverifiable¶

• Tableau prices (tableau.com returns 403, including to a browser; ownership and license tiers settled below).
• SnowPro Core before Advanced: only a May 2023 Snowflake blog says so; current Advanced pages and the FAQ answer are silent.
• Warehouse time travel and snapshot features across platforms (stated as unchecked on the backup page).
• Auto-suspend setting names per platform (stated as unchecked on the cost page).
• Kafka consumer group state descriptions (names settled; the Javadoc gives no per-state text).
• Warehouse time travel and auto-suspend setting names per platform: not attempted in the second pass.
• Not run and not checked: Airflow mapping, Spark/Trino Iceberg readers, MySQL/SQL Server/managed-service commands beyond the doc-level checks above.

Cert guides pass¶

A second pass over the four cert guides added on 2026-11-07 (GCP Associate Data Practitioner, Databricks Data Analyst Associate, Databricks Associate Developer for Apache Spark, MongoDB Associate Data Modeler): exam logistics re-fetched from the vendor pages and guides, every practice question's key and distractors judged against vendor docs, and note claims with a number, default, syntax or named behavior checked. Same classes as above. Counts are approximate groupings of checkable claims.

No keyed answer was wrong and no distractor was accidentally correct in any of the 102 questions. One explanation stated an unsupported capability (GCP Q20).

Fixes¶

Verified without change (selection)¶

• GCP: 2 hours, 50-60 questions, USD 125, English and Japanese, no prerequisites, 6+ months recommended; section weights 30/27/18/25 and all four objective lists match the guide PDF; storage-class minimums, lifecycle actions and 24-hour delay, soft delete 7 days, Cloud SQL HA (about 60 seconds, synchronous, same IP, double cost, standby cannot read), backup retention 1 day to 10 years, scheduled queries (5-minute minimum, on-the-hour duplicates, @run_time), BigQuery subscription at-least-once, CSEK not a Cloud KMS feature, Analytics Hub now BigQuery sharing, BQML model types and Model Registry deployment.
• Databricks analyst: 45 scored plus up to 10 unscored, 90 minutes, USD 200, English, 2 years, 14-day retake at full fee, nine weights summing to 100; managed-table 7-day recovery, OpenSharing naming, 5 GB UI upload limit, SET TAG on DBR 16.1+, APPLY TAG, tag inheritance stops at columns, BROWSE for lineage, result cache 24 hours and UI cache 7 days, predictive optimization on managed tables only, CLUSTER BY AUTO requirements and four-key limit, Genie 50-object and 500-benchmark limits, feedback alone does not change behavior, alert states, Quartz cron, admin-created destinations. The /explain command is in the exam guide's own answer key.
• Spark: same logistics as the analyst exam (guide published 2026-10-08), seven weights summing to 100, Python only; defaults (200 shuffle partitions, 128 MB, 10 MB broadcast, AQE since 3.2.0, 64 MB advisory, skew factor 5 and 256 MB), JDK 17 and G1GC default since 4.0.0, Spark Connect (3.4, gRPC, Arrow, port 15002, no built-in authentication, pyspark-client), deploy modes, save modes, 10,000-row Arrow batches.
• MongoDB: 75 questions, 110 minutes, USD 150, English, online proctored, no prerequisites (exam page, read through a browser because the page is script-rendered); errorAndLog new in 8.1, 32-field compound limit, ESR and ERS wording, shard key factors including reshardCollection from 5.0, Archive, Bucket, Outlier, Inheritance and Schema Versioning page wording, Performance Advisor on M10 or higher.

Still unverifiable¶

• GCP: total certification validity (the FAQ gives only the 3-year renewal extension; the Associate Cloud Engineer row is ambiguous); Firestore and Spanner one-line descriptions (product pages truncated); the BigQuery 90-day long-term storage figure (the pricing and storage pages fetched do not state it); Looker docs-side comparison page; Dataflow "exactly-once by default" and Data Fusion built on CDAP were not re-fetched.
• Databricks analyst: exact meaning of "trusted assets" (set-up page uses the term, does not define it); embedded links, external app integrations and channel apps for Genie (set-up page lists sharing, copy link, OpenSharing and API only); passing score (not published).
• Spark: PySpark stateful operator names (the guide excerpt read did not include them); Databricks serverless using Spark Connect connectivity; behavior of local runs (cache storage level, ANSI union errors) is as run, not documented.
• MongoDB: certification validity and retake rules (gated Certification Program Guide; forum reports of a 15-day wait are unofficial); domain weights and objective text come from the Exam Guide v2.0 read earlier today and sit behind a login viewer, so they were not re-fetched; gradual migration practice; the cardinality-selectivity link; Subset in sharded clusters (guide wording plus inference).

Settled 2026-11-07 (second pass)¶

Public pages only, no logins. Left open: MongoDB Associate Data Modeler validity and retakes (gated Certification Program Guide), Google Associate Data Practitioner total validity (FAQ unchanged), Tableau prices, Wave 2 vendor rereads (dated 2026-12-22, not cheap).
