NEW QUESTION # 21
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 # 22
The following two images show a web page that uses a responsive layout displayed on a mobile device and on a PC.
Displayed on a mobile device:
The layout stacks the content vertically.
Displayed on a computer monitor:
The layout displays the content cards horizontally in multiple columns.
Review the images on the left.
Complete the statements by selecting the correct option from each drop-down list.
Answer:
Explanation:
Explanation:
First drop-down: flex boxes
Second drop-down: background-size
Third drop-down: cover
The layout changes from a stacked mobile layout to a multi-column desktop layout without relying on media queries. That behavior is commonly achieved with responsive flex boxes, where items can wrap naturally based on the available width. The header image must fill the available header area on both mobile and desktop. For that requirement, the correct CSS property is background-size, and the correct value is cover.
background-size: cover scales the image so the entire header area is filled, even if part of the image is cropped. contain would preserve the full image but could leave empty space, and auto would keep the image at its natural size.
NEW QUESTION # 23
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. References/topics: HTML5 form validation, pattern attribute, regular-expression validation, text input constraints.
NEW QUESTION # 24
Identify the filter applied to each image.
Complete the markup by selecting the correct option from each drop-down list.
Note: You will receive partial credit for each correct selection.
Answer:
Explanation:
Explanation:
The first image has a brown/yellow vintage tone, which indicates the sepia(100%) CSS filter. Sepia converts the image colors into a warm monochrome effect commonly associated with aged photographs. The second image appears faded and washed out while retaining the same general image content, which corresponds to opacity(30%); this makes the image mostly transparent, allowing only 30 percent opacity. The third image shows the original beach image with a visible shadow offset behind it, so the correct filter is drop-shadow(8px
8px 10px black). The first two 8px values define the horizontal and vertical shadow offset, 10px defines the blur radius, and black defines the shadow color. saturate(100%) would leave saturation at its normal level and would not visibly create a special effect. grayscale(100%) would remove color entirely and produce a black- and-white image, which is not shown in the visible rows. References/topics: CSS filter property, image effects, sepia(), opacity(), drop-shadow(), graphical enhancement with CSS.
NEW QUESTION # 25
You need to define a grid that meets the following requirements:
* Explicitly sets the width of 6 equal columns of 1 fraction
* Explicitly sets 5 varied sized rows
* Defines 15px of space between each grid column
* Defines 10px between each grid row
Complete the code by selecting the correct option from each drop-down list.
Answer:
Explanation:
Explanation:
display: grid;
grid-template-columns: repeat(6, 1fr);
grid-template-rows: 50px 50px 150px 150px 100px;
grid-gap: 10px 15px;
The correct grid definition starts with display: grid;, which turns the element into a CSS Grid container. To explicitly create six equal-width columns, the correct property is grid-template-columns, and the most efficient value is repeat(6, 1fr). The repeat() function avoids writing 1fr six separate times, while 1fr assigns each column one equal fraction of the available grid width. The five row sizes must be explicitly declared with grid-template-rows, using the exact varied values shown: 50px 50px 150px 150px 100px. This creates five rows with fixed pixel heights. For the spacing requirement, grid-gap: 10px 15px; is the correct shorthand.
The first value controls the row gap, so rows are separated by 10px; the second value controls the column gap, so columns are separated by 15px. References/topics: CSS Grid containers, explicit grid tracks, grid-template- columns, grid-template-rows, repeat(), fractional units, grid gaps.
