OutSystems Architecture Specialist (OutSystems 11) 認定 Architecture-Specialist-11 試験問題:

1. _API module is for

A) A BL becomes a Calculation Engine if it performs complex calculations, (e.g. an invoice calculation engine or an insurance simulator). Engines are usually subject to versions.
B) Logic to Synchronize data in CS's with an external system. Isolating this logic makes the CS completely system agnostic and it's easier to decouple or replace the external system.
C) Technical wrapper to expose an API to External consumers, keeping core services system agnostic and supporting multiple versions of the API.
D) Reusable Core Services with public entities, actions, and blocks.
E) Isolated Business Logic (Actions) or Core Widgets (blocks), to manage complexity, composition or to have its own lifecycle.

2. What does NOT happen due to a lack of architecture concerns?

A) Unmanageable dependencies : System not isolated from each other. Updating or replacing a system has a cascade/snowball effect on other systems
B) Poor service abstraction : Business concepts not correctly isolated, business rules tend to be spread over different systems and little to no code reuse
C) Inflexible and slow-moving legacy systems : adapting legacy systems to business changes may be difficult. Changes in complex and inflexible systems can take a long time
D) Tech Debt : AI Mentor will raise architectural tech debt such as cyclic dependency and side to side dependency

3. Which of the below matches the most to Core Module Pattern - Core Entity Pattern...

A) ... 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
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) ... Entity is exposed as read-only and API is available to centralize business logic for entity creation/update
D) ... 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)
E) 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.
F) ... is needed if data is coming from MULTIPLE external systems. IS will decide which driver to use depending on the data.
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) 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) 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)
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

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

A) ... tries to fetch data from local cache entity, if not there, get single entry from the external system.

5. Which of the below is NOT a reason why application Architecture is important when building quality software solutions?

A) Manages Complexity : Helps reduce emerging complexity by focusing on relevant properties and omitting irrelevant details, thus leading to simpler representation
B) Drives Consensus : Helps create common ground with the team
C) Supports Planning : Helps the team anticipate and build solutions
D) Reduces Risk : Architecture is a cost effective way to mitigate substantial risks and ensure ^ success
E) Facilitate Change : When something comes up that requires you to veer from the origina design or path, architecture of your system can show you exactly what needs to change and help with communication and planning.
F) Reduces Costs : Architecture benefits are not only technical, but affect how you operate
G) Helps Communication : Helps you to get buy in from the business and to communicate overall plan to them
