To recompile only the source code files that have changed since the last build, which can shorten the build time for long-running builds. To remedy syntax errors within the source code, causing the project not to build. To remedy an issue where the source code seems accurate, but Git is indicating a merge conflict. To discard any existing build state before building the project, which can remedy issues where the source code seems accurate yet fails to build.

A commit operation ... Prepares the files to be copied locally. Creates a remote copy of our changed local file(s). Creates a snapshot of the changes so that they can be pushed. Downloads the updated files from the remote repository to our local machine.

After pushing commits to the remote repository for the first time using the command 'git push -u origin master', what shorthand command can you use in future?. 'git push'. 'git push origin'. 'Same as before, git push -u origin master'. 'git push master'.

A team working with Agile methodologies is complaining that they are sending requests for clarification to the Product Owner, but these requests go unanswered. What action should they take?. If there is a question about story, tell the developers to use their best judgement, avoid delay, and discuss the issue in sprint review. Send a note to the Product Owner saying the delays in completing the work will be their responsibility, not the team's. Schedule a problem-solving session with the Product Owner and the other team members. Develop a service-level agree (SLA) that defines certain response times for different types of request and ask the Product Owner to sign off on it.

It's not suitable for projects with unclear requirements.

One of the main principles in the Agile Manifest is ... The highest priority is the final product. No constant interaction between client and development team is necessary. There must be a continuous generation of documentation. People are the main success factor of a project.

The technique of observation when collecting customer information consists of ... Regular meetings between clients and analysts to determine the characteristics of the software product. Analyze "in situ" (in the client company) how the organization works and how the product to be developed fits into it. Study the official documents of the company where its operation is described. Identify a first set of basic requirements when the needs are not clear.

The transition phase of the RUP (Rational Unified Process) methodology is ... Where your source code is produced. Where the product is prepared for delivery to the customer. Where its main architecture is defined. Where the application is designed.

What does the Agile Manifesto indicate?. Documenting requirements up front is more valuable than at the end. Contract negotiation should be used to settle disputes. Responding to change is more valuable than following a plan. Following the plan is essential for not going over budget.

What is known as feedback in the life cycle of software?. Create new tests for error control. Go through the same phase several times. Add new lines of code in the product. The product that is generated after each phase.

When using agile methodologies, if the team needs to make a decision, what is the best course of action?. Take a vote and the majority rules. Identify the person who is most knowledgeable and ask them to decide. Try to achieve consensus. Let the most senior member of the team decide.

When using Agile methodologies, the Product Owner is focused on testing a new system concept in the marketplace as quickly and inexpensively as possible. What is this first-generation product called?. Generation 1 product. Production version. Minimum viable product. Focus group demonstrator.

When using Agile methodologies, which ceremony should the Product Owner not attend?. Daily stand-ups. Code reviews. Story point estimating. Sprint retrospectives.

When using Agile methodologies, which choice is not a benefit generally associated with product demonstrations?. Learn about new requirements. Learn about feature estimates. Learn about feature usability. Learn feature suitability.

When using Agile methodologies, why should a team do refactoring?. It recalibrates the success criteria for the product in the marketplace. It improves the functionality of the product. It improves the design, which can lead improved development efficiency and maintainability. It assigns developers to other teams in order to eliminate personality conflicts.

Which is not an advantage of the V model?. Simple and easy to use, like the cascade model. In each phase some specific deliverables must be made. Integrates development with product maintenance. Useful for small projects with easy to understand requirements.
