Actual exam question for Adobe's AD0-E720 exam

Question #: 15
Topic #: 4

An Adobe Commerce developer needs to display a URL in the template. How would the variable $ur1 be securely output in the template?

A<?php echo $escaper->escapeUrl($url) ?>

B<?php echo $escaper->escapeLink($url) ?>

C<?php echo $escaper->escapeHtml($url) ?>

Show Suggested Answer

Suggested Answer: A, C

To apply a knockout binding to a

to run a function, onClick(), when it's clicked, the developer can use either of the following solutions:

: This solution will use the click binding to execute the onClick() function as an expression when the

is clicked. The function will be called with the current binding context as the first parameter and the event object as the second parameter.

: This solution will use the click binding to execute the onClick function as a reference when the

is clicked. The function will be called with the current binding context as the first parameter and the event object as the second parameter.

The following solutions are not valid and will not work:

: This solution will use the virtual element syntax to apply the click binding, but it will pass a string literal instead of a function expression or reference. This will cause an error, as the click binding expects a function value.

: This solution will use a custom attribute instead of a data-bind attribute to apply the click binding. This is not supported by knockout and will not have any effect.

C won't work for URLs, just HTML.

I’m leaning towards option A too, but I wonder if there’s a specific scenario where escapeLink would be better.

I thought escapeHtml was for general output, not specifically for URLs. This is tricky!

I think it might be option A, but I'm not entirely sure if escapeUrl is the right function for this context.

Easy peasy! `escapeUrl()` is the way to go here. It will properly encode the URL to ensure it's displayed safely in the template.

I'm a little confused by the different escaping functions. Can someone explain the difference between `escapeUrl()`, `escapeLink()`, and `escapeHtml()`? I want to make sure I choose the right one.

Okay, I've got this. The key is to use the `escapeUrl()` function to properly encode the URL and prevent any malicious input from being executed.

Hmm, I'm a bit unsure about this one. I know we need to escape the output to prevent XSS attacks, but I'm not sure which function is the most appropriate here.

Okay, let me see... X.509 and AES-256 seem like the most likely encryption types supported. I'll go with those two.

Wait, there's an 'escaper' object? I was just going to echo the $url variable directly. Glad I checked the answers!

The correct answer is A) escapeUrl($url) ?>. This is the most secure way to display a URL in a template, as it properly escapes the URL to prevent potential security vulnerabilities.
