1. What do know about a Software Configuration Management?


Software configuration management (SCM or S/W CM) is the task of tracing and controlling changes in the software, part of a larger cross-disciplinary field of the configuration management. SCM practices included a revision control and the establishment of baselines.

2. What are the goals of SCM? Why do use Software Configuration Management?


Configuration identification– Identifying a configurations, configuration items, and baselines.

Configuration control– Implementing a controlled change process. This is usually an achieved by setting up a change control board whose primary function is to approved or reject all change requests that are sent to against any baseline.

Configuration status accounting– Recording and reporting all the important information on the status of the development process.

Configuration auditing– Ensuring that configurations contain all their intended parts and are sound with the respect to their specifying documents, including requirements, architectural specifications and user manuals.

Build management– Managing a process and tools used for builds.

Process management– Ensuring adherence to an organization’s development process.

Environment management– Managing the software and hardware that host a system.

Teamwork– Facilitate team an interactions related to the process.

Defect tracking– Making sure each defect has traceability back to the source.

3.Why do need Software Configuration Management?


Configuration Management focuses on the establishing and maintaining the consistency of a system or product throughout its a lifetime. CM is a collection of competencies, techniques, and tools whose purpose is to ensures the consistency of a system’s requirements, functional attributes, and physical properties.

4. What are the advantages of a Software Configuration Management?


  • It reduces a redundant work
  • It effectively manages a simultaneous updates
  • It avoids the configuration-related problems
  • It simplifies coordination between the team members
  • It is helpful in tracing a defects
  • Continuous Integration (CI) is a process of auto

5. What is a Continuous Integration?


Mating the build and testing of code at every time a team member commits a changes to version control.

6. What are configuration management tools?


Chef– Chef is one of the most famous SCM tools. It is basically a framework for an infrastructure development. It provided a support and packages for framing one’s an infrastructure as code.

Puppet– Puppet was first introduced in the 2005 as an open-source configuration management tool. It is written in a Ruby. This CM system allows explaining the state of the IT infrastructure, and then automatically enforces a correct state.

CFEngine– CFEngine is one of the most famous open-source and fully distributed a CM systems and provides automated configuration compute resources. Ansible – Ansible is an open-source platform for the CM, orchestration and deployment of a computing resources.

Juju– Juju is an open-source configuration management and an orchestration management tool. It enabled a applications to be deployed, integrated and scaled on different types of cloud platforms faster and more efficiently.

9. What is meant by a build automation?


Build automation is the process of an automating the creation of a software build and the associated processes include in the compiling computer source code into a binary code, packaging binary code, and running automated tests.

10. Explain the use of the command?


In the Windows Operating System, the use of the command is a program that matches an input field on a text-based user interface with the Windows graphical user interface. It is widely used to perform and an execute commands of different advanced administrative programs. It is also used to troubleshoot or solve any Windows problems.

11. What are the various build automation tools?


There are more Build tools available in the market they are: Maven, Hudson, Gradle, SBT, and Rake.

12. How is Settings.xml different from the pom.xml?


Settings.xml is the user preferences. It lives in main Maven directory (usually $HOME/.m2) and holds on r own settings, like listings for non-public repositories, usernames, and other personalized configuration. pom.xml is a control file for every Maven project or module. It tells Maven which dependencies on the project needs, what processing to apply to built it, and how to package it when it’s to beready. The POM is part of a project itself, and so information that’s necessary to built the project should go there.

13. How do incorporate the SNAPSHOT version into a Maven?


Resolution of dependency ranges should not resolved to a snapshot (development version) unless it is included as an explicit boundary. There is no require to compile against development code unless are explicitly using a new feature, under which a snapshot will become the lower bound of the version specification. As releases are considered to a newer than the snapshot they belong to, they will be chosen over the old snapshot if found.

14.Are compile and install same?


When are installing a program, it means are running an application, which is called an installer. It has a script that contained a set of setup operations that initiate a program to run on a computer. On the other hand, compiling from a source has an advantage of optimizing and configuring a specific system. Therefore, it can be rightly be said that they are not an exactly the same.

15.Explain a Software Configuration Management?


Software configuration management or SCM is a set of rules , processes, and tools that help in an organizing the development process the right way. It helps to keep the present state of the software, which is termed as a baseline. It even enabled a developers to work on new versions for fixes and features. If don’t use SCM, it will made the source code fragmented and unorganized due to which a web development process gets impossible as, without SCM, it is impossible to break a significant pieces of the application.

16. What is the purpose of the SCM or Software configuration management?


First, it helps to accelerate a return on investment of portal investment. It also downstream a risk and cost mitigation.Second, Software configuration management reduced the design gaps between the SCM processes and the environment configuration process. SCM puts a direct effect on a application’s performance.Third, SCM maintains the consistency of the product’s functions, performance, and physical attributes in respect to its design, requirements, and operational information.

17. What is a use of !! command?


It’s used to execute the last command.

With a well-developed software configuration management, an IT developer can be better assess all of a past system implementations of a business and thereby can better cater to a future business needs and changes.

Reliability: Nothing is more disappointing than an unreliable system that is down and require to be repaired frequently. In order to run the business smoothly, a company require reliable software configuration management to ensured that each department in the company is doing their job the right way.

Reduction of risk and a cost: An effective configuration management system saved a lot of money with an operation of record keeping, maintenance, checks, and balances, which help to prevent mistakes and also repetition.

20. What is a transitive dependency? Can override a Transitive Dependency version and If Yes, how?


Transitive dependency is the dependencies not explained directly in the current POM but a POM of the dependent projects.Yes, can override a transitive dependency version by a specifying the dependency in the current POM.

21. Do know Continuous Integration?


It is the process of the automating the integration code from a wide number of a contributors to a single project. The CI process contains a several automatic tools that ascertain an accuracy of the new code prior to integration. The code version of a control system is the crux of the Continuous Integration process. This version is a supplemented along with the other checks like syntax review tools, automated quality tests, and much more.

22. Explain a transitive dependency?


A transitive dependency is the kind of indirect connection between values that leads to the functional dependency. By its nature, it need three or even more features having functional dependency among them. It implied column A in the table depends on the column B via an intermediate connection with column C.

23. Explain a cyclic dependency?


It is a kind of connection between the 2 domains or even more. It gives a rise to a situation where a slave domain is dependent on itself. Not only this, but a master domain also relies on one of its slave the domains. The domain manager decided if there was a cyclic dependency before adding the dependency or not.

24. What do know about a build automation?


In the field of software development, build mainly refers to a process which converts a files and other important things into the software product under the responsibility of the developers. The software product is built into the consumable form. The build includes:
