NEW QUESTION # 57
Which two application features should you implement by using session storage? Choose 2.
Answer: B,C
Explanation:
The correct features are saving temporary authentication tokens and passing form data to a confirmation page.
sessionStorage provides a storage area scoped to the current origin and browser tab, and its data is retained only for the duration of the page session. That makes it appropriate for short-lived application state that must survive page reloads or navigation within the same workflow, but should not remain permanently available after the session ends. Passing form data from an entry page to a confirmation page is a classic session-scoped use case because the data is needed briefly during a multi-page transaction. Temporary authentication tokens can also fit the session-storage model when the token should be tied to the active browser session rather than persisted across future visits. Customized UI/UX settings usually need to persist across sessions, so localStorage or server-side user preferences are more appropriate. Game progress saved for future use is also persistent state, not session-only state. Passing data to a function is ordinary JavaScript memory usage and does not require Web Storage.

NEW QUESTION # 58
Review the markup segment. Which entry will validate successfully according to the required pattern?
Answer: D
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.

NEW QUESTION # 59
Which two background graphics will automatically adjust to different screen sizes? Choose 2.
Note: You will receive partial credit for each correct selection.
Answer: A,B
Explanation:
The correct answers are A and C because background-size: contain and background-size: cover are the CSS values that scale a background image in response to the size of the element or viewport. contain scales the background image as large as possible while preserving the entire image inside the background area. This prevents cropping and maintains the image's aspect ratio, although empty space may appear if the container and image proportions differ. cover also preserves the aspect ratio, but scales the image until the entire background area is filled; this may crop part of the image, but it prevents empty space. Both values are commonly used in responsive design because the image automatically recalculates its rendered size as the page or element changes dimensions. initial resets the property to its default behavior and does not intentionally create responsive scaling. auto uses the image's intrinsic dimensions or proportional automatic sizing, so it does not reliably adjust the graphic to different screen sizes in the way required.

NEW QUESTION # 60
You are creating a dietary request form for an upcoming conference. The form must include the following elements:
* The title " Conference Registration Form "
* A Name input field for the attendee ' s name
* A list of food options the attendee can select by using the mouse or typing Complete the code by moving the appropriate code segments from the list on the left to the correct locations on the right. You may use each code segment once, more than once, or not at all.
Note: You will receive partial credit for each correct response.
Answer:
Explanation:
Explanation:
< !DOCTYPE html >
< html >
< body >
< h1 > The Fitness World Around Us - Spring Conference < /h1 >
< form action= " process.php " method= " post " >
< legend > Conference Registration Form < /legend >
< p > < label for= " name " > Name: < /label >
< input type= " text " id= " name " size= " 30 " maxlength= " 30 " value= " " / > < /p >
< input id= " food " placeholder= " Cuisine " list= " food-choice " size= " 40 " / > < br >
< datalist id= " food-choice " >
< option value= " Vegetarian " > Vegetarian < /option >
< option value= " Traditional " > Traditional < /option >
< option value= " Surprise Me " selected > Surprise Me < /option >
< /datalist >
< input type= " submit " >
< /form >
< /body >
< /html >
The correct solution must satisfy all three stated form requirements. The title " Conference Registration Form
" is supplied by the < legend > element in the first valid code segment. That same segment also includes the required attendee name field by using a < label > associated with an < input type= " text " > . The for= " name
" and id= " name " relationship makes the label programmatically connected to the input, which is the correct HTML form-accessibility pattern. For the food options, the correct choice is the segment that uses an < input
> element with a list attribute connected to a < datalist > element. This is required because the attendee must be able to select an option by using the mouse or type a value manually. A < select > element provides a fixed dropdown list, and radio buttons provide fixed clickable choices, but neither is the best match for a type-ahead list requirement. The < datalist > element supplies predefined options such as Vegetarian, Traditional, and Surprise Me while still allowing keyboard entry through the associated input field.

NEW QUESTION # 61
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.
