NEW QUESTION # 61
You are creating a form that asks a user to enter their phone number. The form must be submitted only if the phone number field is not empty and matches the format 111-444-7777. Which markup should you use?
Answer: B
Explanation:
The correct markup is option D. The type= " tel " input type is appropriate for telephone-number entry, but it does not automatically validate a specific telephone-number format because phone formats vary internationally. MDN notes that tel inputs allow telephone entry but are not automatically validated to a particular format. Therefore, a pattern attribute is required to enforce the exact structure. The regular expression [0-9]{3}-[0-9] {3}-[0-9]{4} requires three digits, a hyphen, three digits, another hyphen, and four digits, matching the requested format such as 111-444-7777. MDN defines the pattern attribute as a regular expression the input value must match for constraint validation. The required attribute is also necessary because the field must not be empty; MDN states that required indicates the user must specify a value before the form can be submitted. Option A only limits length. Option B lacks hyphen validation and required.
Option C hard-codes only specific digits. References/topics: HTML5 validation, tel, pattern, required, regular expressions.
NEW QUESTION # 62
You write the following JavaScript code. Line numbers are included for reference only.
01 < script >
02
03 beststudent = new Student( " David " , " Hamilton " );
04 document.write(beststudent.fullname + " is registered. " );
05 < /script >
You need to write a function that will initialize and encapsulate the member variable fullname.
Which code fragment could you insert at line 02 to achieve this goal?
Note: Each correct answer presents a complete solution.
Answer: A
Explanation:
The correct answer is A because the code at line 03 creates an object by calling a constructor function with the new keyword. A constructor function must be declared with the same identifier used in the new Student( " David " , " Hamilton " ) expression. Inside the constructor, instance members should be assigned through this, because this refers to the newly created object. Option A correctly initializes this.firstname, this.lastname, and this.fullname, so beststudent.fullname is available at line 04 and evaluates to " David Hamilton " . Option B is invalid JavaScript syntax because var student(firstName, lastName) is not a valid function declaration. Option C is also invalid syntax for the same reason: var Student(firstname, lastname) cannot declare a constructor.
Option D uses a valid function declaration, but it assigns firstname, lastname, and fullname without this, which creates or references non-encapsulated variables rather than properties of the constructed object.
References/topics: JavaScript constructor functions, new keyword, object instance properties, this, custom classes.
NEW QUESTION # 63
Review the images on the left.
Complete the statements by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
First drop-down: flex boxes
Second drop-down: background-size
Third drop-down: cover
The correct layout mechanism is responsive flex boxes because the content changes from a vertical mobile arrangement to a wider multi-column layout as space becomes available. Flexbox supports this behavior naturally through flexible item sizing and wrapping, often without needing explicit media queries for every screen size. The header image must fill its visible header region on both mobile and desktop. The correct CSS property for controlling how a background image scales inside its container is background-size. The correct value is cover, because background-size: cover scales the image so that the entire container is covered while preserving the image's aspect ratio. This prevents distortion, although some cropping can occur when the image and container have different aspect ratios. contain would preserve the full image but may leave empty space. auto would use the image's intrinsic size and would not reliably fill the header area. background- attachment, background-clip, and background-repeat do not control image scaling.
NEW QUESTION # 64
Match each stage of Application Lifecycle Management to the task that occurs during that stage.
Move each stage from the list on the left to the correct task on the right.
Note: You will receive partial credit for each correct match.
Answer:
Explanation:
Explanation:
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. References
