Q22. Which of these snippets represents a wrapper that calls jQuery safely and doesn't require repetitive use of the word "jQuery"?
- .
$.ready(function () {
// do stuff
});- .
(function ($) {

})(jQuery);- .
$(function () {
// do stuff
});- .
jQuery(function ($) {
// do stuff

add_action( 'example_hook', 'example_function', $accepted_args, $priority ) -
add_action( 'example_function', 'example_hook', $priority, $accepted_args ) -
add_action( 'example_hook', 'example_function', $priority, $accepted_args ) -
add_action( 'example_function', 'example_hook', $priority )
Q24. You have a search bar on your site. You would like to use a <label> to make the word "Search" visible to screen readers, but you don't want to display the word "Search" on the screen. How can you accomplish this?
- Assign an ARIA state of "hidden" to the label, like this:
<label state="hidden">Search</label> <input type="text" name="search" id="search" /> - Use the built-in WordPress CSS class .screen-reader-text to hide the text from the screen, like this:
<label class="screen-reader-text">Search</label> <input type="text" name="search" id="search" /> - Create a custom CSS class to set a large negative value to the text-indent property to hide the text off-screen, like this:
<label class="hide-this">Search</label> <input type="text" name="search" id="search" /> - The majority of users do not require a screen reader. Remove the label entirely.
if ( ! defined( 'ABSPATH' ) ) {
die;
}
- This is how WordPress detects a plugin's presence. This ensures that the plugin is running from the /wp-content/plugins/ directory. If it is not, the plugin should not run.
- This is a way to prevent naming collisions. ABSPATH is the absolute path to the plugin's directory. If ABSPATH is defined by another WordPress plugin with the same directory slug, the plugin should not run.
- This is a security measure. ABSPATH is the absolute path to the WordPress directory. If the file is called directly, ABSPATH will not be defined and therefore, the plugin should not run.
- This is a compatibility checker. ABSPATH is defined in WordPress core. The plugin checks that the minimum version of WordPress needed to support the plugin is installed. If it is not, the plugin should not run.
- Use !important next to styles if they don't give you the result you want.
- Use hyphens in class names.
- Use spaces to indent each property.
- Avoid CSS shorthand for proper documentation.
Q27. WordPress is translated, at least partially, in more than 200 locales. If you wanted to help translate WordPress into other languages, which contributor group would you join?
- core
- polyglots
- accessibility
- documentation
- Actions are used to add custom functions and remove WordPress functions. Filters are used to make strings translatable for localization.
- Actions are used to add or remove code at runtime. Filters are used to modify data before it is either displayed in the browser or saved to the database.
- Actions are used to assign values to variables at runtime. Filters are used to extract data from actions and display it in the browser.
- Actions are used to add user-inputted data to the database. Filters are used to validate user-inputted data prior to adding it to the database.

Q30. The WordPress REST API is designed to receive and respond to particular types of requests using basic HTML methods.

Q33. If your WordPress site is seriously compromised, what is the best course of action to return your site to good health?
- Determine the date of the attack and restore your site to a backup point prior to that date.
- Hire a third-party service to clean up your site because it is difficult for someone who is not a WordPress security expert to find and remove all traces of an attack.
- Manually delete suspicious files on the server and delete any database tables that are not core WordPress.
- Change your hosting password, your WordPress admin password, and your database password.
Explanation: It's not the cheapest, but it's the most reliable. Restoring the backup might not help if you have backdoor scripts installed outside of WP directory.

Q38. How can you add a custom script that needs to run only on the contact page of a site? The slug of the page is contact.
- Link to the script directly from a template named page-contact.php using the get_header() template tag like this:
get_header( '<script src="/my-script.js"></script>' );
- Use functions.php to conditionally load the script by hooking it to wp_enqueue_scripts(), like this:
add_action( 'wp_enqueue_scripts', 'load_scripts' );
function load_scripts() {
if ( is_page( 'contact' ) ) {
echo '<script src="/my-script.js"></script>';
}
}
- Use functions.php to conditionally load the script by hooking it to wp_enqueue_scripts(), like this:
add_action( 'wp_enqueue_scripts', 'load_scripts' );
function load_scripts() {
if ( is_page( 'contact' ) ) {
wp_enqueue_script( 'script', get_template_directory_uri() . '/script.js' );
}
}
- Link to the script directly from a template named page-contact.php, like this:
<head>
<script src="/my-script.js"></script>
</head>

- disables the theme and plugin editor in the WordPress admin
- disables the ability to edit core WordPress files from either within the WordPress admin or via direct file access
- sets read-only permissions on all files in the WordPress install
More WordPress Security: Disallow File Edit Setting In WordPress. Setting all files to read-only would make auto-updates impossible.
