System Architecture Flashcards

Two development teams need to work on the same application ruleset at the same time without overwriting each other's changes. Which Pega feature supports this?

Answer: Branch rulesets

Branch rulesets isolate each team's changes until they are merged back into the base ruleset.

A rule's availability is set to Final. What does this mean?

Answer: The rule cannot be overridden in another ruleset

Final rules can still be resolved and used, but they cannot be overridden by a rule with the same name in a different ruleset.

When rule resolution finds no matching rule through pattern inheritance, what does it search next?

Answer: The parent class set by directed inheritance

After pattern inheritance, Pega follows the directed parent named in the class definition, up to @baseclass.

Which ruleset validation mode lets rulesets in the same application refer to each other's rules without declaring explicit prerequisites?

Answer: Application Validation (AV)

Under Application Validation, a rule can reference any rule in the application's rulesets and in its built-on applications.

A business manager needs to update a decision table in production without a full deployment. What should the architect configure?

Answer: A delegated rule in a production ruleset listed in the access group

Production rulesets in the access group let authorized users change delegated rules at run time.

What is the main benefit of Pega's Situational Layer Cake architecture?

Answer: It lets rules be specialized by organization, line of business, or situation while common behavior is reused

The Situational Layer Cake lets you reuse common layers and specialize only the parts that differ for a given context.

Which ultimate base class sits at the top of every Pega class hierarchy?

Answer: @baseclass

Every class eventually inherits from @baseclass, the root of the hierarchy.
