Consider the common style guide scenarios presented in this course. Which of the following statements is true?

• A. The "clone a built-in Style Guide" should be used when you want to extend an existing theme.
• B. Build-your-own Style Guide should be used when the changes in the theme are not extensive.
• C. The "specialize a built-in Style Guide" scenario should be used when the changes to the base theme are not extensive.

Which of the below is NOT a reason for adopting Naming Conventions for Modules

• A. Enforce the reference architecture
• B. Reveal nature of each module
• C. Ensure it belongs to the correct layer
• D. Normalize known patterns

Concepts are assembled into Modules in the Assembl are not principles in the Assemble step.

• A. Don't join concepts with different lifecycles
• B. N/A
• C. Apply known design patterns
• D. Isolate reusable logic from Integration logic
• E. Join conceptually-related concepts

Which of the following is an Assembling principle?

• A. Disclose business concepts and integration needs.
• B. Isolate all business concepts.
• C. Keep concepts with different lifecycles apart.
• D. Join all integrations into a single Module.

Which of the below matches the most to Core Module Pattern - ECS Lazy Load variation

• A. ... is a pattern with two modules, a connector module that can be used to encapsulate an external API with the input/output structures and a wrapper module to expose the normalized API to the consumers.
• B. Same as Base ECS pattern, but have a local replica. Store data to serve as a local cache. Pro: Leverage Entity Use, Simpler Integration API. Con: Less impact on source system
• C. ... a wrapper used to contain the logic, actions and data that will expose code that is inside of i external library or to inspect external database and import the data structures so they can be used as entities inside of OS
• D. ... Entity is exposed as read-only and API is available to centralize business logic for entity creation/update
• E. ... is needed if data is coming from MULTIPLE external systems. IS will decide which driver to use depending on the data.
• F. Same as ECS with local replica but API module is provided. So any changes to the external system can notify OS, which OS then gets update from the ERP system (subscription system)
• G. ... caches only summary data that is frequently lister, joined or searched. Full detail for a single entry is fetched directly from external system. Use when whole database too big or costly to synchronize. Details are only required for single entities (not lists)
• H. Same as ECS with local replica but synchronization logic is separated. Pro: Code independence. Consumers of CS is not affected by Sync. Sync can orchestrate several CS
• I. ... Entity is not in Outsystems but in an external ERP system. IS just makes remote call to external system/database. No data is being kept inside OS. Data retrieval may not be optimized as it needs to traverse two different systems to get the information back. Con: Integration API must support all use cases
• J. ... tries to fetch data from local cache entity, if not there, get single entry from the external system. Cache only that record (read-through caching) Use when whole database too big or costly to synchronize. Integration only touches a small portion of the database. Avoid if access to lists of data is needed up front
