NEW QUESTION # 10
You are given the design for an app. The project manager asks you to outline the steps you must take to release and maintain the app.
Move each step from the list on the left to its correct sequence in the application lifecycle on the right.
Note: You will receive partial credit for each correct response.
Answer:
Explanation:
Explanation:
Determine requirements # Develop code # Test the app
#
Monitor performance # Deploy the app
The correct application lifecycle sequence begins with Determine requirements because the team must first define what the app must accomplish, who will use it, and which functional and technical expectations must be satisfied. Since the question states that the design is already provided, the next implementation step is Develop code, where the HTML, CSS, JavaScript, assets, APIs, and app logic are created according to the approved design and requirements. After development, the app must be validated through Test the app.
Testing confirms that the app works correctly, meets requirements, handles user input properly, and does not contain functional defects that would block release. Once testing is complete, the app can be released through Deploy the app, which publishes it to the target environment or makes it available to users. The final operational stage is Monitor performance, where the released app is observed, maintained, updated, and improved based on performance, reliability, defects, and user behavior. References/topics: application lifecycle management, requirements, development, testing, deployment, maintenance.
NEW QUESTION # 11
You need to complete a postal code input form element (post_code). Include attributes to make the field mandatory, set the data type as text, and limit the input to five numeric digits.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
First blank: type
Second blank: pattern
Third blank: required
The first blank must be type because the question requires the input data type to be text, producing type= " text " . The second blank must be pattern because [0-9]{5} is a regular expression that permits exactly five numeric digits. The third blank must be required because the postal code field must be mandatory before the form can be submitted.
NEW QUESTION # 12
You define the Pet class as follows:
class Pet {
constructor(name, breed) {
this.name = name;
this.breed = breed;
this.show = function() {
var text = " < p > Your pet ' s name is " + name + " . The pet ' s breed is " + breed + " . < /p > " ; return text;
};
}
}
You need to derive a Dog class from the Pet class.
Complete the code by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
First blank: class Dog extends Pet {
Second blank: super(name, breed);
The correct syntax for deriving one JavaScript class from another is extends, so the derived class declaration must be class Dog extends Pet {. This creates Dog as a subclass of Pet, allowing Dog instances to inherit members defined by the Pet constructor, including name, breed, and the show() function assigned inside the parent constructor. Inside a derived class constructor, super() must be called before using this. The call super (name, breed); invokes the parent Pet constructor and passes the values required to initialize the inherited name and breed properties. Pet(name, breed); is incorrect because a class constructor cannot be invoked like a normal function. Pet.constructor(name, breed); is also incorrect because it does not call the parent constructor for the current instance. After super() runs, the Dog constructor can safely assign subclass-specific properties such as price and gender. References/topics: JavaScript classes, inheritance, extends, derived constructors, super(), custom class creation.
NEW QUESTION # 13
The following output has more text than will fit in the element.
You need to apply CSS to contain the text inside the element ' s border without creating unneeded scrollbars or losing text. Which attribute setting should you use?
Answer: C
Explanation:
The correct setting is overflow: auto;. The CSS overflow property controls how content behaves when it does not fit inside an element's padding box. The requirement has three parts: keep the text inside the element's border, avoid unnecessary scrollbars, and avoid losing text. overflow: hidden clips overflowing content and does not provide a user-visible scrollbar, so text can become inaccessible. overflow: visible allows excess content to render outside the element's box, failing the containment requirement. overflow: scroll makes the element scrollable, but user agents display scrollbars whether or not content is actually overflowing, which violates the requirement to avoid unneeded scrollbars. MDN describes overflow: auto as clipping overflow content at the padding box while allowing it to be scrolled into view, with scrollbars displayed only when content is actually overflowing. This makes auto the precise choice for a controlled text container. References
/topics: CSS overflow, scroll containers, content clipping, layout flow, preserving overflowing content.
NEW QUESTION # 14
You write the following markup to create a page. Line numbers are included for reference only.
01 < !DOCTYPE html >
02 < html >
03 < head >
04 < style >
05
10 < /style >
11 < /head >
12 < body >
13 < svg height= " 500 " width= " 500 " >
14 < defs >
15 < filter id= " f2 " x= " 0 " y= " 0 " width= " 200% " height= " 200% " >
16 < feOffset result= " offOut " in= " SourceGraphic " dx= " 20 " dy= " 20 " / >
17 < feGaussianBlur result= " blurOut " in= " offOut " stdDeviation= " 10 " / >
18 < feBlend in= " SourceGraphic " in2= " blurOut " mode= " normal " / >
19 < /filter >
20 < /defs >
21 < text x= " 10 " y= " 100 " style= " fill:red; " > Blur Me! < /text >
22 Sorry, your browser does not support inline SVG.
23 < /svg >
24 < /body >
25 < /html >
An SVG blur filter is defined in the markup on the left. You need to apply the SVG blur filter to the text element on the page.
Which CSS code should you insert at line 05?
Answer: B
Explanation:
The correct CSS is option B because the SVG filter is declared inside < defs > with the identifier id= " f2 " .
To apply an SVG filter from CSS, the filter property must reference that filter by URL syntax using the filter' s ID selector: filter: url( " #f2 " );. The text selector targets the SVG < text > element, so the rule applies the defined filter effect to the visible text content, Blur Me!. The filter itself uses < feOffset > , < feGaussianBlur
> , and < feBlend > to create the blurred visual effect. Option A is incorrect because filter: #blur; is not valid filter-reference syntax and does not match the actual filter ID. Option C is incorrect because fill controls paint color, not filter application, and blur is not a valid fill value. Option D uses url(blur), which does not reference the defined f2 filter and omits the required ID reference. References/topics: SVG filters, < filter > , filter IDs, CSS filter: url(#id), SVG < text > styling.
