OutSystems Architecture Specialist (OutSystems 11) Sample Questions:

1. Which of the following is a benefit of having good architecture?

A) Unmanageable dependencies
B) Manages complexity
C) Poor service abstraction
D) Slow-moving legacy systems

2. 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) Isolate reusable logic from Integration logic
D) Join conceptually-related concepts
E) Apply known design patterns

3. Which of the following options denotes the advantages of defining a Style Guide up front?

A) Security and scalability.
B) Speed up the development phase.
C) Allows apps and the Style Guide to be deployed to Production.
D) Improve performance and maintainability.

4. Which of the below matches the most to Library Module Pattern - Extension Pattern...

A) ... a wrapper used to contain the logic, actions and data that will expose code that is inside of ) external library or to inspect external database and import the data structures so they can be used as entities inside of OS
B) ... 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
C) 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
D) ... is needed if data is coming from MULTIPLE external systems. IS will decide which driver to use depending on the data.
E) 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
F) Entity is exposed as read-only and API is available to centralize business logic for entity creation/update
G) Entity is not in Outsystems but in an external ERP system. IS just makes remote call to v 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
H) 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)
I) ... 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)
J) ... 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.

5. Which of the below are FALSE about UI framework?

A) Templates - Defines the structure of the application modules. Templates contains screen p definitions and basic set of functionalities, including authentication.
B) Theme - for the look and feel of your applications, which includes screen layouts, global stylesheet and grid definitions. Contains CSS styles and classes.
C) Patterns - are blocks that provide common and reusable UI. Chat message, date picker and carousel are a few examples. Contains reusable UI components.
D) All of the above are true
