CIA Tools, Technologies, and Prototyping 2 — Questions and Answers
Question 1: Which prototyping fidelity level is most appropriate during the early discovery phase to quickly test multiple conceptual directions with stakeholders?
- High-fidelity interactive prototype
- Low-fidelity paper prototype (Correct answer)
- Coded functional prototype
- Pixel-perfect mockup
Correct answer: Low-fidelity paper prototype
Low-fidelity paper prototypes allow rapid iteration on broad concepts without investing significant time or resources.
Question 2: A data architect needs to model a system where entities have complex, overlapping relationships without a fixed schema. Which database technology is most appropriate?
- Relational (SQL) database
- Graph database (Correct answer)
- Columnar database
- Flat-file database
Correct answer: Graph database
Graph databases excel at representing and querying complex, overlapping entity relationships through nodes and edges.
Question 3: In information architecture, which tool is specifically designed to help practitioners identify how users naturally group and label content?
- Heuristic evaluation
- Card sorting (Correct answer)
- A/B testing
- Tree testing
Correct answer: Card sorting
Card sorting reveals users' mental models by having them organize topics into groups and assign labels.
Question 4: Which technology standard is most commonly used to define and validate the structure of XML documents in enterprise data exchange?
- DTD (Document Type Definition)
- XSD (XML Schema Definition) (Correct answer)
- XSLT
- XPath
Correct answer: XSD (XML Schema Definition)
XSD provides a richer and more expressive way to define XML document structure, data types, and constraints compared to DTD.
Question 5: A CIA practitioner wants to evaluate whether users can find specific content within a proposed navigation structure. Which testing method directly measures this?
- Card sorting
- Tree testing (Correct answer)
- Usability testing
- Cognitive walkthrough
Correct answer: Tree testing
Tree testing (reverse card sorting) presents users with a navigation hierarchy and tasks to find items, measuring findability directly.
Question 6: Which metadata standard is most widely used for describing digital library resources and ensuring interoperability across institutions?
- JSON-LD
- Dublin Core (Correct answer)
- Open Graph Protocol
- Schema.org
Correct answer: Dublin Core
Dublin Core provides 15 core metadata elements widely adopted for describing digital library and archival resources across institutions.
Question 7: When building an interactive clickable prototype to test navigation flows, which dimension of fidelity is being increased compared to a static wireframe?
- Visual fidelity
- Interaction fidelity (Correct answer)
- Content fidelity
- Data fidelity
Correct answer: Interaction fidelity
Adding clickable interactions increases interaction fidelity, allowing users to experience navigation flows without increasing visual design detail.
