Question #2
What is NOT a best practice for Mobile Application Architecture: Limit server side calls?
- A . Limit Server side calls to online transactions or Synchronization. Do the bulk of the operations on the Client Side before passing information to the Server Side.
- B . Synchronize on every screen or online event for better granularity No direct calls to backend systems. Do call to Outsystems Core Services and Outsystems will handle the interaction with external backend systems.

Question #3
There are generally 4 common style guide scenario.
Which of the below is NOT a common style guide scenario?
- A . Specialize a Built-in: Use when introducing changes to an existing theme for multiple apps. First, create a custom theme that REFERENCE the Base Theme. Second, clone a Custom
Template from the Base Template but this custom theme will reference the custom theme created previously. Third, create new applications based on the Custom Theme and Custom Template - B . Built-in Style Guide: Uses Built-in style guide from Outsystems UI. Minor customizations to the Base Theme should be done inside the App Theme.
C, Build Your Own: Use when custom style guide cannot benefit from any existing theme. Just like Clone a Built In scenario, clone both Custom Theme and Custom Template from the Base Theme and Base Template, however clone the Base Theme from Outsystems UI. - C . Since the theme is very basic, front-end developer will have to expand and design the theme from there.
Modify Built-in Style Guide: Use when only small changes are required for single application. First, create a custom theme that REFERENCE the Base Theme. Second, clone a Custom Template from the Base Template but this custom theme will reference the custom theme created previously. Third, reference that application to the custom Theme and Template. - D . Clone a Built-in: Use when introducing extensive changes to existing theme. First, CLONE a custom theme from a Base Theme. Second, clone a Custom Template from the Base Template but this custom theme will reference the custom theme created previously. Third, create new applications based on the Custom Theme and Custom Template.
Base Theme can be Outsystems UI or your own custom theme.

Correct Answer: C
Question #29
Which of the below matches the most to Core Module Pattern – Core Entity Pattern…
- A . is a pattern with two modules, a connector module that can be used to encapsulate an O external API with the input/output structures and a wrapper module to expose the normalized API to the consumers.
- B . … is needed if data is coming from MULTIPLE external systems. IS will decide which driver to use depending on the data.
- C . … 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
- D . … Entity is exposed as read-only and API is available to centralize business logic for entity creation/update
- E . 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 - 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 . … 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
- H . … 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)
- I . 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
- J . … 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
Correct Answer: D
