CTA Quick Reference Guide

A fast-track refresher for the Salesforce Certified Technical Architect (CTA) exam. With 2 hours before a mock board, this distills the full study vault into the patterns, rules, and gotchas you need under pressure.

#SectionDomainOne-Line Summary
1System ArchitectureD1Org strategy, licensing, mobile, reporting, platform limits
2SecurityD2Sharing model, OWD, role hierarchy, field-level security, encryption
3DataD3Data modeling, LDV, migration, archival, external objects
4Solution ArchitectureD4Declarative vs code, AppExchange, build vs buy, Well-Architected
5IntegrationD5Patterns, middleware, APIs, error handling, governor limits
6Dev LifecycleD6CI/CD, environments, branching, testing, governance, CoE
7CommunicationD7Presentation flow, Q&A survival, trade-off articulation, STAR-A
8ArtifactsAllDiagram creation, the Big 3, supporting artifacts, Lucidchart
9Scenario AnalysisAllRequirement extraction, assumption handling, time management

  1. Artifacts — 15 min
  2. Scenario Analysis — 10 min
  3. System Architecture — 10 min
  4. Security — 15 min
  5. Data — 15 min
  6. Integration — 15 min
  7. Solution Architecture — 10 min
  8. Dev Lifecycle — 10 min
  9. Communication — 15 min

Focus on these three sections only:

  1. Artifacts - know the Big 3 diagrams cold (System Landscape, Data Model, Role Hierarchy)
  2. Security - OWD defaults, sharing rules, role hierarchy patterns
  3. Communication - the trade-off formula and STAR-A framework for Q&A
  • Tables first - every section leads with cheat-sheet tables. Read these before anything else.
  • Gotchas second - the :::caution and :::danger callouts flag common exam failures.
  • Mermaid diagrams - visual patterns you can reproduce on the board.
  • Skip prose - these pages are intentionally terse. If something is unclear, follow the wikilink to the deep-dive file.

I chose [APPROACH] because [REASONS]. I considered [ALTERNATIVE] but rejected it because [LIMITATION]. The trade-off is [WHAT YOU GIVE UP], mitigated by [STRATEGY].

StepAction
SRestate the challenge
TThink - pause 3-5 seconds visibly
AAnswer the specific question
RRationale - explain your reasoning
AAdapt - update your design if the challenge reveals a gap

“This diagram shows [what]. The key decision is [decision]. The trade-off is [trade-off]. This connects to [next topic] because [reason].”
