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 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.
Q25. You might see this code in a WordPress plugin. What does it do?
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.
Q26. Which is a best practice for working with WordPress CSS?
Use !important next to styles if they don’t give you the result you want.

Q28. What is the difference between an action and a filter?
Actions are used to add custom functions and remove WordPress functions. Filters are used
to makestrings 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.
Q29. If you activate or update a plugin and it breaks your site so that you cannot manage it via
wp-admin, how can you disable the plugin?

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.

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

<input type="text" id="title" name="title" />
$title = $_POST[ 'title' ];
https://www.icontrolwp.com/blog/more-wordpress-security-disallow-file-edit-setting-wordpress/
The code sample does not use the GET method. It should be wrapped in
the get_post_field() function and look like this $title = get_post_field( $GET[ 'title' ]
);
The code sample does not sanitize the form data. It should use
the sanitize_text_field() function and look like this: $title = sanitize_text_field(
$_POST[ 'title' ] );
There is no error. The code follows WordPress best practices.
The code sample does not allow for translation. It should use a translation function and look
like this: $title = __( $_POST[ 'title' ];
