CEA-C01 common mistakes
CEA-C01 · Understand the traps and how to avoid them.
Treating the exam's architecture framework as a generic EA methodology and answering from general TOGAF-style memory instead of the specific framework the exam tests, e.g., describing phases or artifacts that belong to a different framework.
Candidates often study EA from prior commercial framework experience and assume terminology carries over; the exam's framework has its own named components, and superficially similar terms mean different things.
What to do instead
Build a one-page glossary that maps each exam-framework term to a plain-language definition and explicitly note where it differs from frameworks you already know. Practice restating framework definitions in your own words without borrowing language from other frameworks.
Conflating the framework's foundational concepts (e.g., architecture domains, abstraction levels, and stakeholder concerns) and using them interchangeably when a question asks which concept applies.
The concepts are related and overlap in casual usage; under time pressure candidates pick the most familiar-sounding term rather than the one matching the question's precise scope.
What to do instead
Create a comparison table with one row per foundational concept listing its definition, the question it answers, and a distinguishing example. Drill by classifying short scenarios into exactly one concept and justifying the exclusion of the nearest alternative.
Choosing a framework model or viewpoint based on which one the candidate remembers best rather than matching the model to the stated stakeholder concern and abstraction level.
Questions present a stakeholder need and several plausible models; candidates pattern-match on keywords instead of evaluating whether the model's purpose actually addresses the concern.
What to do instead
For each model in the exam framework, memorize three things: the concern it addresses, the stakeholders it serves, and the abstraction level. Practice scenario questions by first writing the concern, then eliminating models whose stated purpose does not cover it.
Mixing up views, viewpoints, and the underlying model, describing a view as if it were the specification or the model as if it were the presentation.
The terms are near-synonyms in everyday speech, and candidates skim definitions once and rely on intuition afterward.
What to do instead
Memorize a strict one-line distinction (viewpoint = the specification/conventions; view = the resulting representation for a stakeholder; model = the underlying structured content) and answer at least a dozen questions that hinge only on that distinction until it is automatic.
Selecting an implementation or migration approach without first establishing the baseline and target states and the gap between them, jumping straight to a transition plan.
Implementation content feels concrete and actionable, so candidates gravitate to it; questions that test sequencing are answered as if the plan came first.
What to do instead
Adopt a fixed reasoning order for any implementation question: baseline, target, gap, then transition/roadmap. Write that order at the top of scratch notes and explicitly check whether the question supplies the baseline and target before evaluating options.
Ignoring governance and architecture-change control in implementation scenarios, treating the architecture as a one-time deliverable rather than something governed through change.
Candidates focus on producing artifacts and forget that the framework includes ongoing oversight, compliance review, and change management of the architecture itself.
What to do instead
For every implementation scenario, ask 'who approves changes to this architecture and how is conformance checked?' Memorize the framework's governance touchpoints and practice identifying the governance gap in otherwise plausible answer options.
Confusing architecture planning inputs with outputs, e.g., treating stakeholder concerns or business drivers as deliverables, or treating the architecture roadmap as a starting assumption.
Planning questions list many plausible-sounding items, and candidates do not track direction of flow from drivers through requirements to the plan.
What to do instead
Draw the planning flow once (drivers and concerns in, requirements and scope, then plan and roadmap out) and classify every listed planning artifact as input, activity, or output. Rehearse with questions that ask what must precede a given planning step.
Skipping stakeholder identification and concern elicitation and going directly to scope definition, so answers omit stakeholders whose concerns should have driven the scope.
Scope feels like the 'real' planning work and stakeholders feel like a formality; candidates underestimate how many questions hinge on who the architecture serves.
What to do instead
Before answering any planning question, list the stakeholders implied by the scenario and their concerns, then check whether the chosen option accounts for them. Practice questions where the correct answer is a stakeholder-engagement step rather than a technical scoping step.
Producing or selecting a model that is technically valid but violates the framework's modeling conventions, such as missing required relationships, wrong level of detail, or inconsistent naming and identifiers.
Candidates focus on whether the diagram 'makes sense' and overlook the rules that make models consistent and reusable across the architecture.
What to do instead
Memorize the framework's modeling rules checklist (required elements, relationship semantics, naming and identifier conventions, appropriate detail level) and apply it as a pass/fail test to each candidate model in practice questions.
Analyzing an architecture in isolation, failing to trace impacts across domains or to integrate analysis results back into the architecture, so answers miss cross-domain dependencies or integration consequences.
Questions are often framed within one domain, and candidates answer locally without considering how a change propagates to other domains, models, or the integrated architecture.
What to do instead
For every analysis question, run a fixed cross-check: which other domains, models, and stakeholders does this touch, and how do the results feed back into the architecture? Practice by writing the impact chain for each scenario before reading the answer options.
