Authentic IT Specialist Certification Exam INF-306 Questions Answers

The correct segment is D because named grid-region layouts are defined with grid-template-areas. This CSS Grid property specifies named grid areas, establishes the cells in the grid, and assigns names to those cells. The syntax requires each row of the grid template to be written as a quoted string, with repeated names indicating that the named area spans multiple columns or rows. In the shown layout, heading spans the entire top row, menu occupies the left column across lower rows, content spans the central area, right occupies the right-side area, and contact spans the bottom content region. Options B and C are incorrect because named grid-area strings do not belong in grid-template-rows or grid-template-columns; those properties define track sizing, not named layout regions. Option A defines explicit column and row sizes but does not define the semantic named areas shown in the mockup.

The correct answer is D because the layout shown is a named-area CSS Grid layout. The mockup contains five semantic regions: the top header area for the logo and page title, a left-side menu, a central main content area, a right-side additional content area, and a bottom copyright/contact area. In CSS Grid, this type of visual structure is defined with grid-template-areas, where each quoted string represents one grid row and each repeated name represents how far that area spans across columns. In option D, heading spans the full top row, menu occupies the left column across the lower rows, content fills the main center region, right fills the additional content region, and contact spans the bottom row to the right of the menu. Option A only defines row and column sizes and does not name the five content areas. Options B and C are invalid for this purpose because named layout strings do not belong in grid-template-rows or grid-template-columns.

< input id= " phone "

pattern= " [0-9]{10} "

placeholder= " 0000000000 " >

The correct first attribute is pattern because the requirement is to validate the entered value against a specific format: exactly ten numeric digits and no symbols. The regular expression [0-9]{10} means that only digits from 0 through 9 are allowed, and exactly ten of them must be entered. This prevents values such as 123-456-7890, (123)4567890, or 123 456 7890 because those contain symbols or spaces. The correct second attribute is placeholder, not value, because the input should initially display all zeroes but that displayed text must not be submitted or stored with the form. A placeholder is hint text shown when the field is empty; it disappears when the user enters real data and is not submitted as the control’s value. By contrast, value= " 0000000000 " would actually prepopulate the input and could be submitted if the user did not change it. The required option is not selected because the question focuses on format validation and display hint behavior, not mandatory completion.
