Question 1:
Case Scenario:
A leading e-commerce company is refactoring its legacy
monolithic application into a microservices architecture. This
transition is intended to facilitate independent system scaling,
reduce downtime during deployments, and improve overall
agility.
Question:
Which of the following challenges is most critical when
transitioning from a monolithic system to a microservices
architecture?
a) Inability to scale hardware resources

,b) Complex distributed data management
c) Slower adaptation to new business logic
d) Increased upfront capital expenditure
Correct ANS: b) Complex distributed data management
Rationale:
Microservices require decentralized data management with each
service potentially owning its own database. Managing data
consistency, ensuring proper communication, and handling
transactions across distributed services pose significant
complexities compared to a monolithic setup.

Question 2:
Case Scenario:
A multinational software firm is adopting an Agile transformation
to manage several cross-functional teams working on a large-scale
product. However, the integration of legacy systems across
geographic locations is proving difficult.
Question:

,What is the most effective strategy for addressing integration
challenges with legacy systems in an Agile transformation?
a) Immediate replacement of legacy systems
b) Gradual API-first integration with iterative feedback loops
c) Isolated pilot projects without involving legacy integration
d) Strict waterfall planning for legacy components
Correct ANS: b) Gradual API-first integration with iterative
feedback loops
Rationale:
An API-first approach promotes designing robust communication
interfaces that bridge legacy and modern systems. Combined with
Agile’s iterative cycles, this strategy allows teams to
incrementally integrate and test the legacy components,
minimizing risks and disruption.

Question 3:
Case Scenario:
A financial technology company is implementing a new enterprise
application and is seeking to decouple its complex business logic
from varying implementation details across platforms.

, Question:
Which design pattern best addresses decoupling the abstraction
from its implementation, enabling independent variability of
each?
a) Adapter
b) Observer
c) Bridge
d) Decorator
Correct ANS: c) Bridge
Rationale:
The Bridge pattern separates the abstraction from its
implementation, allowing them to vary independently. This
decoupling is critical in large-scale systems where business logic
(abstraction) should not be tightly bound to platform-specific
details (implementation).
