Question #1
A developer has a catalog XML file that must be imported into a sandbox with the Business Manager Import & Export module. The file will be uploaded over WebDAV. In which WebDAV location must the file be placed so that it is listed for import?
Correct answer: B
Explanation
Files that Business Manager can import are read from the Impex/src directory, usually in a subfolder such as Impex/src/catalog. Cartridges holds code versions and Static holds storefront static resources, so neither is scanned by the import modules.

Question #2
A developer creates a hooks.json file that maps a hook name to a script in a custom cartridge. Which cartridge file must contain a hooks property that points to hooks.json so that the hooks are registered?
Correct answer: B
Explanation
Hook registration starts in the cartridge's package.json, where the hooks property holds the relative path to hooks.json. Without that reference, the platform does not read the hook mappings.

Question #3
A developer adds a route that processes a standard form POST in an SFRA controller. Which middleware function must be added to the route to verify the CSRF token before the route handler runs?
Correct answer: B
Explanation
csrfProtection.validateRequest checks the submitted token and stops the request if it is missing or invalid. generateToken is used on the route that renders the form so the token can be placed in the page, which is the tempting but wrong choice for the submit route.

Question #5
A developer creates a string attribute named ecoRating on the Product system object type. A merchant opens a product in Merchant Tools > Products and Catalogs > Products and cannot find the field on any tab. What should the developer do?
Correct answer: D
Explanation
Attributes appear in the Business Manager editor only when they belong to an attribute group, which is managed in the Attribute Grouping tab of the system object. Site-specific, searchable and mandatory settings change how the value behaves but do not place the field on the page.

Question #6
A developer defines a newsletter form in forms/default/newsletter.xml. The email field has mandatory="true" and a regex attribute. The POST route of the controller must continue only when every field satisfies the constraints from the XML definition. The form is loaded as follows: var newsletterForm = server.forms.getForm('newsletter'); Which condition correctly tests the submission?
Correct answer: C
Explanation
A form object returned by server.forms.getForm exposes a valid property that is true only when all fields pass the mandatory, length and regex rules in the form definition. req.form is just the raw posted data and has no validation state.

Question #7
A developer adds this route to a controller in an SFRA cartridge. Requesting Wishlist-Show returns an empty response and no template is rendered. No error is written to the log. server.get('Show', function (req, res, next) { var items = getWishlistItems(req.currentCustomer); res.render('wishlist/show', { items: items }); }); What is the cause?
Correct answer: B
Explanation
In SFRA, res.render only queues the template, and the response is produced when the handler calls next() and the route completes. Omitting next() produces an empty response without an exception. A missing middleware function would change access rules but would not blank the page.

Question #8
A merchant needs a new site that sells in euros and displays prices that include tax. A developer opens Administration > Sites > Manage Sites to create the site. Which two settings does the developer specify for the site? Choose 2 answers.
Select 2 answers.
Correct answer: C, D
Explanation
Currency and taxation type (net or gross) are site-level settings chosen in Administration > Sites > Manage Sites. Tax jurisdictions and tax tables are configured separately under Merchant Tools > Ordering > Taxation, and price books are assigned to the site afterward, so neither defines the site's currency or tax type.

Question #9
A developer needs to grant an external system access to specific resources of the Data API. In which Business Manager module are the OCAPI client permissions configured?
Correct answer: A
Explanation
Client IDs, resources, allowed methods and attribute access for the Shop and Data APIs are defined as JSON in Administration > Site Development > Open Commerce API Settings. Roles & Permissions controls what Business Manager users can open, which is a common point of confusion, but it does not set OCAPI client permissions.

Question #10
A single-page app hosted at https://shop.northwind.example calls the OCAPI Shop API. In the browser, requests to /s/NorthwindUS/dw/shop/v23_2/products/883 fail with a CORS error. The same request with the same client ID succeeds in Postman. Which change resolves the issue?
Correct answer: A
Explanation
Browsers enforce CORS, so the Shop API settings must list the calling origin in allowed_origins for the client ID. Postman does not apply CORS checks, which is why the call works there and shows that resource permissions are already correct. The Data API settings and cache time do not affect cross-origin access.
