INF-306 Exam Dumps : HTML5 Application Development

First drop-down: four

Second drop-down: maxlength

Third drop-down: email, password, and phone

The form contains four user-entry input elements: email, password, confirm password, and phone. Since the requirements state that all fields must be completed, the required attribute must be applied to all four inputs. The password field must prevent entries longer than eight characters, so the correct length-control attribute is maxlength, not max; max applies to numeric/date-style value ranges, while maxlength limits character count in text-style inputs. The phone field also benefits from maxlength because its placeholder format has a fixed visible structure. Finally, completed pattern attributes are needed for email, password, and phone because each has a required format rule: the email must match the placeholder-style address format, the password must use only letters and numbers, and the phone number must follow the placeholder format such as 123-45-678. The title attribute should accompany these patterns to produce meaningful browser validation messages.

Application Lifecycle Management organizes website creation into ordered stages that move from intent to implementation and long-term support. The Plan stage comes first because it establishes why the website exists, who the audience is, and what goals the application must satisfy. The Design stage converts those requirements into structure, including page layout, navigation, interface organization, and visual arrangement. The Develop stage is where the website is built by writing HTML markup, CSS styling, JavaScript behavior, and integrating required assets or APIs. The Test stage evaluates whether the completed website functions correctly and is usable according to requirements; this includes checking features, layout behavior, validation, and user workflows. The Deploy stage publishes the finished website to the target hosting or production environment so users can access it. Finally, the Maintain stage occurs after release and includes monitoring, updating, fixing defects, improving compatibility, and keeping content or functionality current.

The correct methods are setItem(), removeItem(), and clear(). The HTML5 Web Storage API exposes localStorage as a persistent key-value storage object for the current origin. Data stored in localStorage remains available after page reloads and browser restarts unless it is explicitly removed or cleared. setItem(key, value) stores a value under a named key or updates the value if the key already exists. removeItem(key) deletes one specific key-value pair from storage. clear() removes all key-value pairs from the storage object for that origin. These methods are part of the standard Storage interface used by both localStorage and sessionStorage. write is not a Web Storage method; it is associated with document-writing behavior, not application state storage. cookie is also incorrect because cookies are a separate browser storage mechanism accessed through document.cookie, not a method of localStorage.
