    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because the process of software development involves several stages, including requirement analysis, design, development or coding, testing, and maintenance. These stages are collectively known as the Software Development Life Cycle (SDLC). The SDLC provides a structured approach to developing software, ensuring that all necessary steps are followed and that the final product meets the required specifications and quality standards.

    Rate this question:

  • 15. 

    Earlier a defect is found the cheaper it is to fix it.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Finding a defect earlier allows for quicker identification and resolution, which ultimately reduces the cost of fixing it. When a defect is detected early in the development process, it requires less effort and resources to rectify, as it hasn't had the chance to propagate and impact other parts of the system. Additionally, early detection minimizes the potential for customer dissatisfaction or negative consequences that could arise from a defect going unnoticed. Therefore, finding defects early is beneficial in terms of cost and overall project efficiency.

    Application should be stable. Clear Design and Flow of the application is needed for Automation testing

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given statement is true because in order for automation testing to be effective, it is important that the application being tested is stable. If the application is unstable or has bugs, it can lead to inaccurate test results and unreliable automation scripts. Additionally, a clear design and flow of the application is necessary for automation testing as it helps in identifying test scenarios, creating test scripts, and executing them efficiently. Without a clear design and flow, it can be difficult to automate the testing process effectively.

    Cost of Production = Right The First time cost(RTF) + Cost of Quality

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given statement is true. The cost of production is determined by the sum of two factors: the cost of producing a product or service correctly the first time (RTF) and the cost of maintaining quality. This means that in order to calculate the total cost of production, both the initial cost of producing the product correctly and the ongoing cost of ensuring its quality must be considered. Therefore, the statement is correct.

    Inode :

    • File owner identifier

    • None

    • File path

    • Date

    Correct Answer
    A. File owner identifier
    Explanation
    The correct answer is "File owner identifier" because an inode is a data structure in a Unix-like file system that stores metadata about a file, including information about the file's owner. The inode contains the user ID of the file's owner, which serves as an identifier for the owner of the file.

    . Which of the following views can you use to display reports

    • None

    • Grid and graph

    • Grid

    • Graph

    Correct Answer
    A. Grid and graph
    Explanation
    The correct answer is Grid and graph because these views allow the user to display reports in a visual and organized manner. The Grid view presents the data in a tabular format, making it easy to compare and analyze different values. On the other hand, the Graph view uses visual representations such as charts and graphs to present the data, making it easier to identify trends and patterns. By using both Grid and graph views, users can have a comprehensive view of the report data and make informed decisions based on the information presented.

    Why unix access I/O? 

    • All of these

    • Create file.

    • Open file

    • Change the file properties.

    Correct Answer
    A. All of these
    Explanation
    Unix allows access to I/O (input/output) operations for various reasons. It provides the ability to create files, which is essential for storing data and information. Unix also allows users to open files, enabling them to read and write data to these files. Additionally, Unix allows users to change the properties of files, such as permissions and ownership, providing control and security over the file system. Therefore, Unix supports all of these operations to facilitate efficient and effective management of files and data.

    Rate this question:

  • 27. 

    Why inode is used? 

    • File path

    • Date

    • Fileowner identifier

    Correct Answer
    A. Fileowner identifier
    Explanation
    Inode is used to store the fileowner identifier. This identifier helps in determining the owner of the file, which can be useful for access control and permission management. The inode contains metadata information about the file, including the owner's user ID. This allows the operating system to enforce file permissions and restrict access to certain files based on the fileowner identifier.

    Data warehousing and on-line analytical processing (OLAP) are _______ elements of decision support system. 

    • None of the given

    • Unusual

    • Essential

    • Optional

    Correct Answer
    A. Essential
    Explanation
    Data warehousing and on-line analytical processing (OLAP) are essential elements of a decision support system. This is because data warehousing involves the collection, organization, and storage of large amounts of data from various sources, which is crucial for making informed decisions. OLAP, on the other hand, allows users to analyze this data through multidimensional views and complex queries, providing valuable insights for decision-making processes. Without these components, a decision support system would lack the necessary data and analytical capabilities to effectively support decision-making.

    Software testing which is done without planning and Documentation is known as  

    • Functional testing.

    • Regression testing

    • Unit Testing

    • AdHoc Testing

    Correct Answer
    A. AdHoc Testing
    Explanation
    AdHoc testing refers to a type of software testing that is performed without any formal planning or documentation. It involves randomly testing the system without following any specific test cases or scripts. This type of testing is usually carried out when there is limited time or resources available, or when there is a need to quickly identify defects or issues in the software. AdHoc testing is not systematic and may not cover all possible scenarios, but it can be effective in finding certain types of defects that may not be identified through formal testing methods.

    Which of the following holds the data which does’nt belongs to either fact table or dimensional table? 

    • None of these

    • Slowly changing dimensions

    • Confirmed dimensions

    • Junk dimensions

    Correct Answer
    A. Junk dimensions
    Explanation
    Junk dimensions hold data that does not belong to either a fact table or a dimensional table. These dimensions are created to store attributes that do not fit into any existing dimension. Junk dimensions are typically used to consolidate low cardinality flags, indicators, or other miscellaneous attributes that are not related to the main dimensions of the data model. They help to simplify the data model and reduce the number of dimension tables required.

    Types of Data mart?

    • Dependent

    • Independent

    • Hybrid

    • All

    Correct Answer
    A. All
    Explanation
    The correct answer is "All" because there are three types of data marts: dependent, independent, and hybrid. A dependent data mart relies on a centralized data warehouse for its data, while an independent data mart is a standalone database that is created specifically for a particular business function or department. A hybrid data mart combines elements of both dependent and independent data marts, allowing for a combination of centralized and decentralized data storage and processing. Therefore, the answer "All" encompasses all three types of data marts.

    Defect report can be? 

    • Both

    • Non-judgemental

    • Numeric

    • None

    Correct Answer
    A. Both
    Explanation
    A defect report can be both non-judgmental and numeric. Non-judgmental means that the report should only state the facts about the defect without assigning blame or making subjective evaluations. Numeric means that the report may include quantitative information such as the severity or frequency of the defect. Therefore, a defect report can encompass both these characteristics, providing objective information about the defect without making any judgments and potentially including numerical data.
