Right Answer: To deal with large volumes of data in Ab Initio, I use partitioning to split the data into smaller, manageable chunks, utilize parallel processing to enhance performance, optimize graphs by minimizing data movement, and leverage components like the Rollup and Join to efficiently aggregate and combine data. Additionally, I ensure proper memory management and use the Ab Initio Co>Operating System for distributed processing.
Right Answer: Alfresco integrates with external systems like SAP or Salesforce primarily through:
* **CMIS (Content Management Interoperability Services):** A standard protocol for accessing content repositories.
* **REST APIs:** Alfresco provides REST APIs for interacting with its functionalities.
* **Custom Integrations:** Developing custom integrations using Java, JavaScript, or other programming languages to connect directly with system APIs or databases.
* **Pre-built Connectors/Modules:** Alfresco Marketplace may offer pre-built connectors for specific systems.
Right Answer: Agile is an iterative approach that focuses on collaboration and flexibility, allowing for changes throughout the development process. Waterfall is a linear and sequential model where each phase must be completed before moving to the next, making it less adaptable to changes. DevOps is a culture and set of practices that combines software development (Dev) and IT operations (Ops) to improve collaboration, automate processes, and shorten the development lifecycle, emphasizing continuous integration and delivery.
Right Answer: A software developer primarily focuses on writing, testing, and maintaining code to create software applications. They are involved in the implementation of features and fixing bugs. In contrast, a software engineer applies engineering principles to software development, often involving system design and architecture. A software architect, on the other hand, is responsible for the overall structure and high-level design of software systems, making decisions about technology and frameworks used.
Right Answer: The RTE (Runtime Environment) manages inter-ECU communication by using a standardized communication mechanism that allows different ECUs (Electronic Control Units) to exchange data through defined interfaces. It utilizes the COM (Communication) module to handle message transmission and reception, ensuring that data is sent and received according to the AUTOSAR specifications, including support for different communication protocols like CAN, LIN, and Ethernet.
Right Answer: Block elements take up the full width available and start on a new line (e.g., `<div>`, `<h1>`). Inline elements only take up as much width as necessary and do not start on a new line (e.g., `<span>`, `<a>`). Inline-block elements are similar to inline elements but can have width and height set, and they respect margins and padding (e.g., `<img>`, `<button>`).
Right Answer: Event bubbling is a JavaScript event propagation method where an event starts from the target element and bubbles up to its ancestors in the DOM hierarchy. Event delegation is a technique that involves attaching a single event listener to a parent element to manage events for multiple child elements, leveraging event bubbling to handle events efficiently.
Right Answer: Promises in JavaScript are objects that represent the eventual completion (or failure) of an asynchronous operation and its resulting value. They allow you to handle asynchronous code more easily by providing methods like `.then()` for success and `.catch()` for errors.
`async` and `await` are syntactic sugar built on top of promises. An `async` function always returns a promise, and within an `async` function, you can use `await` to pause execution until a promise is resolved, making the code easier to read and write as if it were synchronous.
Right Answer: HTML5 is the latest version of HTML, which includes new features such as native support for audio and video, new semantic elements (like `<article>`, `<section>`, and `<header>`), improved parsing rules, and better support for web applications with APIs like local storage and canvas. HTML, on the other hand, refers to earlier versions that lack these enhancements.
Right Answer: `var` is function-scoped or globally-scoped and can be re-declared and updated. `let` is block-scoped, can be updated but not re-declared in the same scope. `const` is also block-scoped, cannot be updated or re-declared, and must be initialized at the time of declaration.
