OutSystems Architecture Specialist (OutSystems 11) Sample Questions:

1. Which of the below is NOT a disadvantage of having a fragmented system or microservices?

A) Complicated Debugging and troubleshooting : root cause may be deep inside the chain of services
B) Inter-process communication : network latency and hiccups
C) All of the above
D) Security : need to manage credentials and access management
E) Multiple transactions committed independently
F) Monitoring & Logging : for effective monitoring & logging, requires centralized service
G) Fault tolerance : communication errors, service consistency
H) Limited data mashup in memory and limited to APIs

2. Foundation may have non-business services and business services in them

A) TRUE
B) FALSE

3. Which of the below matches the most to Core Module Pattern - ECS with Direct Integration Pattern

A) . 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
B) 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)
C) ... Entity is exposed as read-only and API is available to centralize business logic for entity creation/update
D) ... 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
E) ... Entity is not in Outsystems but in an external ERP system. IS just makes remote call to p 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
F) ... 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.
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) ... is needed if data is coming from MULTIPLE external systems. IS will decide which driver to use depending on the data.
I) ... 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
J) 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

4. What is NOT a best practice for Mobile Application Architecture: Local Storage?

A) Sync data required per use case: Sync summary data on Session start. On data selection, sync p its details.
B) Sync on every screen or online event
C) Adopt the correct sync frequency: Either at process start and online or at process/transaction end and online

5. Which of the following recommendations should be applied to the Core layer?

A) Core modules should have Front-end Screens for testing purposes.
B) Core modules should have public Read-only Entities.
C) Core modules should not have Core Entities.
D) Core modules should not have business logic.
