Free Salesforce B2C Commerce Developer practice questions

Question 1

Cumulus Financial's commerce team is releasing a new storefront build. The release lead asks the developer how code should reach production given the platform's upload restrictions. Which two practices should the developer follow? Choose 2 answers.
A. Package the whole code version as a .zip and upload it once to production's Code Deployment page
B. Use Code Replication to transport the active code version from staging to the production instance
C. Turn off the client certificate requirement on staging so a build server can upload without a second factor
D. Upload the new cartridges into a new, inactive code version on the staging instance and test it there
E. Upload the cartridges over WebDAV straight into production's active code version during a quiet period

Accepted Answer

Correct answer: B. Use Code Replication to transport the active code version from staging to the production instance | D. Upload the new cartridges into a new, inactive code version on the staging instance and test it there
The Code Deployment guide recommends uploading code into an inactive version on staging, testing it, and then using Code Replication, which copies the active code version from staging to production. Production rejects WebDAV uploads into its active version, and Salesforce mandates disallowing direct code uploads to production. Two-factor upload to staging (credentials plus client certificate) is required and should stay on. Uploading a .zip of a code version isn't supported; cartridges are uploaded instead.

Question 2

A Universal Containers developer opens Administration > Sites > Manage Sites and clicks New to create a sandbox site for a European storefront. Which three settings does the developer enter on the New Site page? Choose 3 answers.
A. The default currency for the site
B. The colon-separated cartridge path for the storefront code
C. The taxation type, Net or Gross
D. The site ID, using alphanumeric characters, hyphens and underscores
E. The storefront catalog and the inventory list that the site will use

Accepted Answer

Correct answer: A. The default currency for the site | C. The taxation type, Net or Gross | D. The site ID, using alphanumeric characters, hyphens and underscores
The New Site page asks for the ID, the default currency, the taxation type (Net or Gross) and a description. The cartridge path is entered afterward on the site's Settings tab. Catalogs and inventory lists are assigned to the site later from Merchant Tools, because a new site starts with no products, prices or other business data.

Question 3

A Universal Containers developer deploys a home page template that contains <isslot id="home-promo" context="global" description="Home page promo"/>. The storefront renders nothing in that spot, and the log has an entry for the slot ID. What should happen next?
A. Create a slot configuration for home-promo in the Business Manager content slots module
B. Wrap the isslot tag in an iscache tag so the slot is rendered on the next request
C. Add a context-object attribute that points to the current basket so the slot can resolve
D. Add the cartridge that contains the template to the Business Manager site's cartridge path

Accepted Answer

Correct answer: A. Create a slot configuration for home-promo in the Business Manager content slots module
When no slot is defined in the database for a slot ID, isslot renders no content and writes a log entry, so the merchandiser or developer must create a slot configuration in Business Manager. Caching changes how often the output is regenerated, not whether a configuration exists. Global slots don't need a context object. The storefront site's cartridge path is already rendering the template, so the Business Manager cartridge path isn't involved.

Question 4

An Ursa Major Solar developer is checking availability messages for a backorderable solar lantern. Its inventory record has a stock level of 2 and a backorder allocation of 5. Refer to the code below:

var ProductMgr = require('dw/catalog/ProductMgr');
var product = ProductMgr.getProduct('UMS-LANTERN');
var levels = product.getAvailabilityModel().getAvailabilityLevels(10);
var summary = levels.inStock.value + '/' + levels.backorder.value + '/' + levels.notAvailable.value;

What is the value of summary?
A. 2/5/0
B. 10/0/0
C. 2/0/8
D. 2/5/3

Accepted Answer

Correct answer: D. 2/5/3
getAvailabilityLevels(quantity) splits the requested quantity across availability statuses. With 2 in stock and 5 backorderable, a request for 10 returns 2 in stock, 5 on backorder and 3 not available, so summary is 2/5/3. 10/0/0 ignores the stock level entirely. 2/0/8 ignores the backorder allocation. 2/5/0 drops the 3 units that no status can cover. The inStock, backorder and notAvailable properties return Quantity objects, so .value reads the number.

Question 5

A Bloomington Caregivers developer reviews these Shop API settings for an existing realm with OCAPI enabled:

{
    "_v": "23.1",
    "clients": [
        {
            "client_id": "bbbbbbbbbbbbbbbbbbbbbbbbbbbbbb",
            "resources": [
                { "resource_id": "/baskets", "methods": ["post"], "read_attributes": "(**)", "write_attributes": "(**)" },
                { "resource_id": "/baskets/*", "methods": ["get"], "read_attributes": "(**)", "write_attributes": "(**)" }
            ]
        }
    ]
}

The app creates and reads baskets, but a PATCH request to /baskets/{basket_id} that updates the currency is declined. Which change fixes it?
A. Add "patch" to the methods array of the /baskets/* resource entry
B. Change _v to the OCAPI version the app calls, because _v must match the request URL version
C. Change write_attributes on /baskets/* to (currency) so the property can be included in requests
D. Add a /baskets/** resource entry with ["get"], because PATCH uses the subresource path

Accepted Answer

Correct answer: A. Add "patch" to the methods array of the /baskets/* resource entry
The methods property is an HTTP method filter, so a resource entry that lists only get declines PATCH; adding patch to the /baskets/* entry allows the update. _v is the version of the configuration file structure and is independent of the OCAPI version in the request. write_attributes already allows all properties with (**), and narrowing it would not add the missing method. PATCH on a basket targets /baskets/{basket_id}, which /baskets/* already matches, and a GET-only entry would not allow PATCH anyway.

Question 6

A Cumulus Financial developer must review today's customerror files on a staging instance. Which two ways can the developer reach the log files? Choose 2 answers.
A. Open Administration > Operations > Custom Log Settings and use the Download tab beside each category
B. Connect an sFTP client to the instance's Logs folder on port 22 using the Business Manager user name and password for that instance
C. Connect a WebDAV client with Business Manager credentials to /on/demandware.servlet/webdav/Sites/Logs on the instance
D. In Business Manager, open Administration > Site Development > Development Setup and use the Log files link under WebDAV Access
E. Open Merchant Tools > Reports & Dashboards and export the error log report for the current day as a CSV file

Accepted Answer

Correct answer: C. Connect a WebDAV client with Business Manager credentials to /on/demandware.servlet/webdav/Sites/Logs on the instance | D. In Business Manager, open Administration > Site Development > Development Setup and use the Log files link under WebDAV Access
The Log Files page describes both routes: the Log files link in the WebDAV Access section of Development Setup, and a WebDAV client pointed at https://<instance>/on/demandware.servlet/webdav/Sites/Logs with a Business Manager user that has the right access. The same page states sFTP is not supported. Custom Log Settings configures levels and categories but does not serve the files. Reports & Dashboards is a merchant analytics tool, not a log viewer.

Question 7

A Northern Trail Outfitters merchandiser unchecked Enabled on the nto.http.loyalty.get service in Business Manager during a vendor outage. Refer to the controller code below:

var result = loyaltyService.call({ customerNo: customerNo });
if (!result.ok) {
    Logger.warn('Loyalty status {0}, reason {1}', result.status, result.unavailableReason);
}

What is written to the warn log?
A. Loyalty status SERVICE_UNAVAILABLE, reason DISABLED
B. Loyalty status ERROR, reason DISABLED
C. Loyalty status ERROR, reason CIRCUIT_BROKEN
D. Loyalty status SERVICE_UNAVAILABLE, reason CONFIG_PROBLEM

Accepted Answer

Correct answer: A. Loyalty status SERVICE_UNAVAILABLE, reason DISABLED
When a service is disabled, no call is made and the Result has the status SERVICE_UNAVAILABLE with the unavailable reason DISABLED, which getUnavailableReason() returns for that status. ERROR is the status for a general service error after a call is attempted. CONFIG_PROBLEM means the service was not configured correctly, which differs from being switched off. CIRCUIT_BROKEN is the reason when the circuit breaker blocks the call, and it accompanies SERVICE_UNAVAILABLE, not ERROR.

Question 8

A Universal Containers developer tries to add another custom attribute to the Content system object type and is blocked. The object already has 50 custom attribute definitions, 12 of them localizable. What explains the result?
A. Content allows at most 50 custom attribute definitions, and localizable definitions count toward it
B. The Content limit is 500 definitions, so the block comes from the attribute group size instead
C. Only 25 non-localizable attributes are allowed per object, so the block is from that quota
D. Localizable attributes count double, so the object has really used 62 of its allowance

Accepted Answer

Correct answer: A. Content allows at most 50 custom attribute definitions, and localizable definitions count toward it
The business objects page lists a maximum of 50 custom attribute definitions for Content and other extensible system objects, 500 for Product and for site and organization preferences, and states that localizable custom attribute definitions count toward the limit, so 50 definitions hit the cap. Localizable definitions count once, not twice. The 500 limit applies to Product, not Content. There is no separate 25-attribute quota for non-localizable attributes.

Question 9

The base Cart-AddProduct route used by Northern Trail Outfitters already posts each added item to an external inventory reservation service. A developer must change how that step builds the reservation request, and a teammate proposes server.append in the overlay cartridge to send a corrected reservation. What should the developer do instead?
A. Use server.append and remove the original reservation step from the chain with removeListener before it runs
B. Append a step that calls the service again and passes a flag so the inventory system ignores the first reservation
C. Copy the corrected reservation code into app_storefront_base so every site on the instance picks up the fix
D. Replace the route in the overlay cartridge so the original middleware, including its reservation call, doesn't execute

Accepted Answer

Correct answer: D. Replace the route in the overlay cartridge so the original middleware, including its reservation call, doesn't execute
With server.append, the original middleware chain runs before the added step, so a third-party call in the original chain still runs and could run twice. The SFRA guide recommends replacing a route when you need to change individual steps or when the route interacts with a web service. You can't remove a single step with event emitter listeners, because removeListener doesn't recognize named emitters. Editing app_storefront_base voids its upgrade path and is explicitly discouraged.

Question 10

A Get Cloudy Consulting developer adds a gift-message form, defined in forms/default/giftMessage.xml, to an SFRA route. The route gets the form object with the server module's getForm function and then calls res.render('checkout/giftMessage') with no data argument. The template reads pdict.giftForm.message, but the field never renders. What should the developer change?
A. Pass the form object to the template in the data argument of res.render(), for example under the giftForm key
B. Call clear() on the form before rendering it so that the in-memory form object is created again for the request
C. Move giftMessage.xml into the cartridge's templates/default/forms folder so that the template can find it
D. Include the form definition in the template with <isinclude> so that the template loads the form fields itself

Accepted Answer

Correct answer: A. Pass the form object to the template in the data argument of res.render(), for example under the giftForm key
The Forms guide says form data is read in templates through pdict, but the form is available only if the controller passes the object returned by getForm to the template, by adding it to the data passed when rendering. isinclude includes templates, not form definitions. Calling clear() only resets the values the in-memory form keeps during the session; it doesn't make the form visible to the template. Form definitions belong in the cartridge's forms folders (such as forms/default), not under templates.

Question 11

An AW Computing developer must integrate a partner's FTP price-list drop and a legacy SOAP order service. Which two statements about the service types' callbacks are correct? Choose 2 answers.
A. A SOAP service must implement initServiceClient to get the WebReference2 port, and it also implements execute
B. For an FTP service, when the script doesn't call setOperation(), the execute callback runs when the service is called
C. An HTTP service must implement initServiceClient to build its HTTPClient, because the framework doesn't create it
D. The Generic service type wraps dw.net.HTTPClient, so its parseResponse callback receives the HTTP client object
E. The HTTP Form type sends the parameters given to call() as a JSON body by default, so no createRequest is needed

Accepted Answer

Correct answer: A. A SOAP service must implement initServiceClient to get the WebReference2 port, and it also implements execute | B. For an FTP service, when the script doesn't call setOperation(), the execute callback runs when the service is called
The Web Services page says the FTP type has setOperation(), and if it isn't called, the execute callback defined in the service definition runs when the service is called. It also says SOAP services implement two more callbacks, initServiceClient and execute, and that initServiceClient is required only for SOAP because other client types are created automatically. That is why HTTP services do not need initServiceClient. The Generic type doesn't wrap any class, and the HTTP Form type builds a URL-encoded form POST from the call parameters.

Question 12

AW Computing is launching its storefront in four languages and wants translators to work without touching template logic. Which approach does Salesforce recommend for storefront text?
A. One template set, with its text externalized into properties files translated per locale
B. One template set with <isif> branches on the locale that hold the text for each language
C. Content assets for every label, so merchandisers translate the text in Business Manager
D. A separate copy of every template for each locale, with translated text written into each copy

Accepted Answer

Correct answer: A. One template set, with its text externalized into properties files translated per locale
Salesforce recommends one template set with localizable strings externalized into resource files, which is the approach SFRA uses: the template resource bundles are translated, not the templates. Separate template sets per locale duplicate display logic and are the less preferred option. Locale branches in templates put translations into logic, and turning every label into a content asset isn't the documented approach for template text.

Question 13

An Ursa Major Solar ERP integration, an existing OCAPI integration on a realm where OCAPI is enabled, replaces a customer address through the OCAPI Data API with an HTTP PUT request. It works on a sandbox but is blocked on staging and production. Which two changes let the integration perform the same logical PUT on those instances? Choose 2 answers.
A. Send the request with POST and the request parameter method=PUT
B. Send the request with PATCH, because PATCH replaces the whole resource like PUT does
C. Send the request with PUT but add the Content-Length: 0 header to pass the block
D. Send the request with GET and the full address document in the query string
E. Send the request with POST and the header x-dw-http-method-override: PUT

Accepted Answer

Correct answer: A. Send the request with POST and the request parameter method=PUT | E. Send the request with POST and the header x-dw-http-method-override: PUT
The OCAPI HTTP Methods page says that for security reasons PUT is blocked from making direct calls against production or staging instances, and that you perform a logical PUT through POST by overriding the method. The override can be given as the method request or form parameter or as the x-dw-http-method-override header, with the value in upper case. PATCH is a partial update that only changes provided properties, so it isn't the same as PUT. GET is a safe method that never changes server state, and the Content-Length: 0 advice is for requests without a body, not a way around the PUT block.

Question 14

An AW Computing developer builds a custom attribute editor that lets marketers pick a store on a map. The component type sets the attribute to "type": "custom" with an editor_definition that references the editor ID, and the editor files are in int_awc_editors, which is on the storefront site's cartridge path. In the visual editor, the attribute shows no map. What should the developer do?
A. Move the editor's meta definition and script into experience/components, next to the component that uses the editor
B. Load the editor's JavaScript with assets.addJs in the storefront page template, so the visual editor can run it
C. Add int_awc_editors to the cartridge path of the Business Manager site, where custom attribute editors are loaded
D. Change the attribute type to string, because editor definitions are applied only to string attributes in the editor

Accepted Answer

Correct answer: C. Add int_awc_editors to the cartridge path of the Business Manager site, where custom attribute editors are loaded
The cartridge that contains the custom attribute editor's meta definition, script and client-side code must be added to the cartridge path for the Business Manager site, because the editor runs in the Business Manager visual editor. A custom attribute editor is used with an attribute of type custom and an editor_definition, so switching to string removes it. Editor files belong under experience/editors, not experience/components. Storefront assets aren't loaded into the editor, which runs each custom editor in its own iframe.

Question 15

Cloud Kicks' SFRA OnRequest hook loads the shopper's loyalty profile and recomputes recommended categories on every request. The Code Profiler shows the hook costs about 40 ms per request. What does the documented guidance say?
A. Expensive custom logic of more than 10 ms in OnSession and OnRequest should be limited or moved
B. OnRequest logic runs asynchronously after the response is sent, so it doesn't add page time
C. OnRequest logic is excluded from page caching rules, so the cost only matters on uncached pages
D. OnRequest logic runs once per session, so the 40 ms is paid only on the first page of each visit

Accepted Answer

Correct answer: A. Expensive custom logic of more than 10 ms in OnSession and OnRequest should be limited or moved
The Site Performance page's storefront best practices say to limit expensive (more than 10 ms) custom server logic in OnSession and OnRequest, so a 40 ms hook should be reduced or moved. Claims that OnRequest logic runs only once per session, is excluded from caching rules or runs after the response is sent would make the cost irrelevant, and they contradict the documented advice to limit this logic. The Code Profiler lists ONREQUEST calls as a request result type, which is how the 40 ms cost was measured.

Question 16

A Bloomington Caregivers developer writes a chunk-oriented script module for a nightly volunteer-hours export and leaves out every optional function. Which three functions must the module still provide? Choose 3 answers.
A. write, which receives the list of items for the chunk and returns nothing
B. beforeStep, which runs once before any chunk is read, processed or written
C. read, which returns one item or nothing when there are no more items
D. process, which applies business logic to an item and returns one item
E. getTotalCount, which returns the total number of items before chunking starts

Accepted Answer

Correct answer: A. write, which receives the list of items for the chunk and returns nothing | C. read, which returns one item or nothing when there are no more items | D. process, which applies business logic to an item and returns one item
The Create Custom Job Step Types page marks read, process and write as required for chunk processing: read returns one item or nothing, process transforms an item and returns one item, and write receives the list of items for a chunk. The page marks getTotalCount and beforeStep as optional; getTotalCount is called once before chunk processing to support progress monitoring, and beforeStep runs before all items of all chunks are handled. Unless the steptypes file names other functions, the module must export functions named read, process and write.

Question 17

A Get Cloudy Consulting developer creates common/layout/promoLayout.isml with a header include and a footer include, and wraps the body of a campaign template like this:

...

The storefront shows the header and footer but none of the campaign body. What is the cause? A. The isdecorate tag needs a .isml suffix on the template path, so the body is rendered as plain text B. promoLayout.isml doesn't contain an tag, so the decorated content is omitted from the output C. The campaign body must use inside isdecorate, because inline markup is ignored D. Decorator templates must sit in a decorators folder, so the body is skipped and only the includes run

Accepted Answer

Correct answer: B. promoLayout.isml doesn't contain an tag, so the decorated content is omitted from the output A decorator template marks where the wrapped content goes with ; if the decorator has no isreplace tag, the decorated content is omitted. Template paths don't need the .isml suffix, which is appended automatically. There is no required decorators folder: SFRA's own decorators live in common/layout. The wrapped content can be any markup, so inline HTML inside isdecorate is valid.

Question 18

Before moving to a newer compatibility mode, a Universal Containers developer must find every template that still uses <iscache status="off"/>, including its code location. Where should the developer look?
A. The sysevent log, which records template compile warnings when a code version activates
B. The deprecation log, which records each deprecated iscache usage with its code location
C. The customwarn log, which is written whenever a template sets a status value on a tag
D. The quota log, which lists every template that turned off page caching on each server

Accepted Answer

Correct answer: B. The deprecation log, which records each deprecated iscache usage with its code location
Setting status="off" on iscache is deprecated, and the system writes messages to the deprecation log that warn about the usage and show the code location of each occurrence. The quota log covers object and API quotas. The customwarn log holds messages from Logger.warn calls in custom code. The sysevent log shows app server registration and cartridge-related events such as code version activation, not deprecated tag usage. To disable caching going forward, omit the iscache element instead.
