                                NEW QUESTION # 14
                                Which two code segments declare a JavaScript method? Choose 2.

                                Answer: C,D

                                Explanation:
                                The correct selections are B and C because both define a function as a member of an object context, which is the essential JavaScript pattern for declaring a method. MDN defines a method as a function that is a property of an object. It also shows that a function expression can be assigned to a variable or property and then invoked later. In option B, Score: function() { ... } represents an object-literal method property. This pattern is commonly used when defining custom objects, prototypes, configuration objects, or class-like structures in JavaScript. In option C, this.Score = function() { ... } assigns a function to the current object instance, creating an instance method that can be called through that object. Option A does not declare a method; as written, it is only an invalid or incomplete variable assignment and does not use the function keyword or method syntax.
                                Option D invokes Score() and assigns its return value to a; it calls a function rather than declaring a method.

                                NEW QUESTION # 15
                                Move the appropriate attributes from the list on the left to the correct descriptions on the right. You may use each attribute once, more than once, or not at all.
                                Note: You will receive partial credit for each correct match.

                                Answer:

                                Explanation:

                                Explanation:
                                pattern # Provides a way to set a regular expression that the value must match placeholder # Provides a way to set default text that displays until focus is placed in an element required # Provides a way to set form elements as mandatory multiple # Provides a way to allow more than one file or email address in a single input The correct matches are based on standard HTML5 form validation and input-attribute behavior. The pattern attribute defines a regular expression that the input value must satisfy before the form can be submitted successfully. It is commonly used for structured values such as phone numbers, codes, postal formats, or custom identifiers. The placeholder attribute supplies short hint text inside an input field, helping the user understand the expected value before entering data. The required attribute makes a form control mandatory; if the field is empty, constraint validation prevents successful submission. The multiple attribute allows a single input to accept more than one value, specifically for controls such as input type= " file " and input type= " email " , where users may upload multiple files or enter multiple email addresses. The maxlength attribute is not used in these matches because it limits the maximum number of characters that can be entered, but none of the listed descriptions asks for character-length restriction. References/topics: HTML5 form attributes, constraint validation, pattern, placeholder, required, multiple, input validation.


                                NEW QUESTION # 16
                                Review the markup segment. Which entry will validate successfully according to the required pattern?

                                Answer: A

                                Explanation:
                                The valid entry is A, assuming the OCR-corrupted option represents the intended secret-code format: four letters, a hyphen, two digits, a hyphen, four digits, a hyphen, and four letters. The HTML pattern attribute defines a regular expression that an input value must satisfy during constraint validation. MDN specifies that pattern is used to define a regular expression the input value must match. In the intended pattern, the first group must contain exactly four alphabetic characters, the second group exactly two numeric digits, the third group exactly four numeric digits, and the final group exactly four alphabetic characters. Option A satisfies that structure: kukX is four letters, 04 is two digits, 4938 is four digits, and WJDF is four letters. Option B fails because the final group Uhj6 contains a digit. Option C fails because the first group includes a digit and the digit grouping/hyphen structure is wrong. Option D fails because 23h contains a letter where only digits are allowed. References/topics: HTML5 form validation, pattern attribute, regular-expression validation, text input constraints.


                                NEW QUESTION # 17
                                You need to use a flexbox so that new content you add to the container appears at the highest point on a vertical list. You want to achieve this goal without specifying an order. Which value should you use for flex- direction?

                                Answer: C

                                Explanation:
                                The correct value is column-reverse. The flex-direction property defines the main axis of a flex container and determines whether flex items are laid out horizontally, vertically, or in the reverse direction. column creates a vertical layout where items flow from the top of the container toward the bottom. If new content is appended after existing content, normal column layout places that new item later in the visual list, typically lower on the page. column-reverse preserves a vertical main axis but reverses the visual direction, so later items in the source order appear at the highest visual point of the list. This satisfies the requirement without using the order property on individual flex items. row and row-reverse are incorrect because they create horizontal layouts, not vertical lists. The reverse-direction flex values should be used deliberately because visual order can differ from DOM order, but for this exam scenario, column-reverse is the value that places newly appended vertical content at the top. References/topics: CSS flexbox, flex-direction, main axis, column layout, reverse visual flow.


                                NEW QUESTION # 18
                                The development team just released a new version of an app for your team to test. Which three tasks should you perform during testing? Choose 3.

                                Answer: A,C,D

                                Explanation:
                                The correct testing tasks are to verify application functionality, find defects, and ensure the app meets design specifications. Testing occurs after development produces a build and before acceptance or deployment decisions are made. Its purpose is to compare the implemented application against expected behavior, requirements, and design specifications. Option A is correct because functional testing confirms that user workflows, controls, validation rules, scripts, and page interactions work as intended. Option C is correct because defect discovery is a core testing responsibility; testers identify failures, inconsistencies, regressions, and unexpected behavior so the development team can correct them. Option D is correct because the app must be evaluated against the documented design, including layout, navigation, responsiveness, accessibility expectations, and feature behavior. Asking customers to submit bugs or feature requests is a feedback or product-management activity, not the primary task of an internal test cycle immediately following a development release. Checking syntax errors is primarily handled during development, linting, editing, or build processing; a released test build should already parse and execute sufficiently for functional testing.
