Correct answers
The tasks User interface and Database schema both can be done
simultaneously.
The task Students support system can start when the task Result management is completed.

A developer team has used some components during the development for which they do not have access to the source code (only binaries are available). Therefore, for debugging they explore the documentation and code examples to understand the correct use of the components' code. Which of the following debugging strategies is used by the developer scheme?

Correct answer
Blackbox debugging
Consider the design of an online shop that sells computers, laptops, and related accessories, along with software licenses. All products other than software licenses are delivered by its delivery partners, while software licenses are delivered online. The design has an interface iDelivery, which is implemented by different kinds of delivery classes. However, during the process of implementing the online delivery class, the developers discovered that many of the functions declared by iDelivery were not relevant to online delivery. However, since they implement iDelivery, they are forced to implement those functions that are not relevant.
Identify the SOLID principle that is not fulfilled by the design.
Single responsibility principle
Open-close principle
Liskov substitution principle
Interface segregation principle
Dependency inversion principle
Correct answer
Interface segregation principle
Factory design pattern
Builder design pattern
Adapter design pattern
Facade design pattern
Correct answer
