Which platform is best for Desktop Apps on Windows?

Answer 20

.NET

Question 21

Which platform would you recommend for developing Web API that:

1. Is cross Platform
2. Is dynamically Typed
3. Offers great performance

Answer 21

node.js

Question 22

Which front end JavaScript framework is better for quick and simple web front end?

Answer 22

React.
Angular is a comprehensive framework with long learning curve, and is less optimized for quick and simple apps.

Question 23

Which one of the following capabilities DOES NOT exist in typical relational databases?
Transactions
Foreign Keys
Unstructured Data Support

Answer 23

Unstructured Data Support
Relational databases support only structured data (with some notable exceptions). NoSQL databases are the preferred way to store and query unstructured data.

Question 24

What is the relationship between Non-Functional Requirements and Quality Attributes?

Answer 24

Quality Attributes fulfi the non-functional requirements.
The various Quality Attributes map to the Non-Functional Requirements and are implemented in the architecture.

Question 25

Which quality attributes defines the ability of the system to grow and shrink according to load?

Answer 25

Scalability

Question 26

Which Quality Attribute deals with the easiness of adding new code to the system?

Answer 26

Extensibility

Question 27

Which Quality Attribute is used when designing the system's monitoring?

Answer 27

Manageability. The manageability quality attribute helps us manage the application, including its monitoring.

Question 28

What is the purpose of the Layered Architecture?

Answer 28

Makes to component much more modular. Using layered architecture helps us modularize the component, and switch entire functionality by replacing a single layer.

Question 29

In a classic layered component, can the SI layer call directly to the DAL?

Answer 29

No. Layers cannot skip the layer beneath them, and usually there is a BL layer beneath the SI layer.

Question 30

Using Interfaces, what can we avoid?

Answer 30

Strong Coupling. Interfaces allow us to separate the actual implementation of two classes using contract - Interface - thus prevent the strong coupling between them

Question 31

Using Constructor Injection greatly helps:

Answer 31

With Testing. Using Constructor Injection really simplifies testing, that can inject some mock types when running tests.

Question 32

If your interface contains 25 members, which principle of SOLID does it break?

Answer 32

Interface Segregation Principle

Question 33

Which of the following is NOT part of the System Architecture?

Answer 33

Defining the graphic theme of the system

Question 34

What problem is solved by using Services Directory?

Answer 34

The Spider Web. Using Services Directory we avoid the Spider Web, where each service communicates directly with other services, thus having a dependency on them.

Question 35

Which component is essential for implementing Stateless Architecture?

Answer 35

Load Balancer. Load Balancer enables balancing the load between services, which is the whole point of stateless architecture.

Question 36

Would you cache telemetry data that's received every 5 seconds and retrieved by end users every 1 minute on average?

Answer 36

No. We usually want to cache data that is rarely changed and frequently retrieved, and this case is the complete opposite.

Question 37

Which messaging method would you prefer between two services: The first one - receives data from various sensors for processing The second one - processes the data and saves it in DB. Assume that performance are not top priority, but all the data must be processed, and we want to avoid data loss as much as possible.

Answer 37

Queue. Queue is probably the best match here. It's the most reliable messaging method, on the expense of performance.

Question 38

What are the sub-sections of the Components' Drill Down section?

Answer 38

Role, Tech stack, Architecture, development instructions

Question 39

What is the purpose of the Architecture Document?

Answer 39

To describe what should be developed and how, and to lay out the requirements.

Question 40

What are an audience of the Architecture Document?

Answer 40

Developers Project Manager CTO

Question 41

Which requirements are detailed in the architecture document?

Answer 41

Functional and Non-Functional

Question 42

What is the purpose of the executive summary?

Answer 42

To provide a high level overview of the architecture and boost confidence in your network.

Question 43

Which section in the document describes the technology stack?

Answer 43

In the components' drill down or in the Architecture overview section. If the system is comprised of various, separate services, each runs in its own process, then the tech stack is described per service. On the other hand, if the system is a single process one, then the tech stack is described in the architecture overview section.

Question 44

What are Micro Services?

Answer 44

An architecture in which various functionalities ar implemented as separate, loosely coupled services that interact with each other using standard, lightweight protocol.
