The import process can’t create a new catalog from a CSV file 29) When exporting catalog through a CSV file, is it possible to export product bundles? No, the CSV export only contains product attributes and does not include columns for product bundles. 30) What is the best practice to make sure that your catalog CSV file fits for the SFCC standards?Export a catalog first and modify it with your changes, then navigate to catalog import and select which catalog you want to update during the import process, also make sure all your attributes are valid before beginning the import process. 31) Is it true that we can assign products to only one category inside storefront catalog?No, we can assign product to more than one category. 32) What is Rule-based categorization?Rule-based categorization rules automatically assign all products that fit a criteria to a category. You create rule sets to establish these criteria and all products that fit the criteria are automatically assigned to the category 33) When product inherits the category attributes?If category is designated as the primary category for a product, that product inherits the assigned category attributes. 34) Can we copy the category without copying the products assigned to this category?Yes. For example, you want to create a Flash Sale category for climbing gear and you have a Climbing Gear category already defined with product assignments. You can copy the Climbing Gear category without its products, and preserve the category attributes, product attribute definitions, search refinement definitions sorting rule, and page meta tag rules of your original Climbing Gear category in the Flash Sale category. 35) Is it possible to schedule a category to be shown on a storefront within a specific time?Yes, you just navigate to category you want to schedule and set date and times for Online From and Online To. 36) Which product attributes can be used as search criteria on your storefront?Every product attribute, including custom attributes, which is specified in your Search Refinement Definitions. 37) What for do we need Page Meta Tag Rules tabs in SFCC?Page meta tags are used in HTML documents to provide structured data about a web page. Meta tags don’t appear on the page itself, but in the page code, describing page content and making it easy for web crawlers/search engines to populate your page in search results 38) Given a task to implement new product type - cologne, with available volumes0.2 and 0.3 L, what are the steps to implement this feature?You should add new custom attribute — volume (with type set of strings) for a product system object,DO NOT MARK IT AS required, next make it searchable by adding it to search refinement definitions, create demo product if needed, assign it to category, hit indexes rebuild and good to go. 39) What are slicing rules in SFCC?Slicing rule is used to determine whether the variation product appears as a single search result with a single image or is sliced and appears with a search result for each variation product with its own image 40) What is the difference between UUID and ID?

It hosts the live site that is used by customers. 65) What is realm?In general, realm is a container for all your instances including Primary Instance Group (PIG) And Secondary Instance Group (SIG). 66) Can we have multiple realms in SFCC?In most cases, you have a single realm in which you can develop, stage, and deploy multiple sites with different branding or locales. The people managing the storefront site don’t have to be in the same location. Sites can share product catalogs or have different catalogs.Note! If you have different lines of business or global teams that each have their own processes or business policies, consider maintaining multiple realms. You can also have separate realms if you have distinct organizations with separate back-end integrations, schedules, or other concerns that make it advantageous to let each team manage their sites independently. Sites in the same realm can share the product catalog for product data. Sites in different realms can’t share data through the catalog structure. However, you can share data by importing it into different realms. 67) What is the minimum and maximum number of Sandboxes which can be created in Secondary Instance Group?The minimum number of sandboxes in a SIG is 3, and the maximum is 47.3??? 68) What are software deployment stages in SFCC?The software deployment stages for B2C Commerce development include Sandbox, Build and Merge, Staging, Development, and Production. 69) What is quota in SFCC?Quotas are part of the Demandware Platform. They are used to monitor platform resource usage in custom code. Platform resources include memory, application server threads, database table sizes, and so on. Typically, when a quota is exceeded, custom code is using platform capabilities inefficiently, and a more efficient solution is possible. 70) How many quota types are there in SFCC? There are many quota types, which can be grouped into API and Object quota.The Demandware Platform was designed to be used as an ecommerce system. With that usage scenario in mind, certain constraints and limits were set during design and implementation to ensure the efficiency and stability of solutions built on top of the platform. These limits concern memory usage, resource consumption, API calls, and the number of business objects. 71) What happens when a quota is exceeded?A quota is either “enforced” or “not enforced.” If an enforced quota is exceeded, an exception is thrown, which prevents the current operation from completing. The exception cannot and should not be caught within the customization. The design criteria must be avoidance of quota violations. Examples for quota violations are:• a Collection with too many elements was created in memory, or• too many persistent objects of a certain type were created in an instance.If an enforced quota is exceeded in a storefront request, the general error page appears. If an enforced quota is exceeded during a standard import, a Data Warning or Data Error is reported. If a quota is not enforced, the platform does not take an action when the limit is exceeded. 72) What are API quotas?API quotas may define limits on number of object instances, object sizes, runtimes, number of executions per page, or prevent the execution of a B2C Commerce Script method or pipelet in the storefront. 73) What are Object quotas in SFCC?Object quotas and object relationship quotas define a limit on the number of objects. Object quotas typically limit the number of objects of a particular type per instance. Object relationship quotas limit the number of objects that may be associated with one object of that type. 74) What is SFCC Model-View-Controller (MVC) Architecture?Software architectural model whereby the underlying data (model) is separate from the user interface (view), so that changes to the user interface don’t affect data handling, and data can be reorganized without changing the user interface. The decoupling of data access and business logic from data presentation and user interaction is facilitated by a controller. 75) What is an SFCC Storefront? Your online ecommerce site powered by B2C Commerce. A single instance can include multiple storefronts. 76) What for do we need isml tag?To include the contents of one template inside another or the contents of another URL. 77) Can we include both URL and template path in one single tag? You must include either template or URL, but not both. 78) What is the maximum include depth in SFCC? The maximum include depth is fixed to 10. 79) Can remote include other remote includes?Yes, remote includes can include other remote includes. 80) What should we do to include text string in our templates instead of hard- coding them?We can use the Resource class methods. 81) How can we implement page caching in SFCC?You can enable page caching in Business Manager; and use the ISML tag within a template to control what parts of a page are cached and for how long. 82) When caching should not be used? If the page data is frequently updated. 83) What is static page content in SFCC?Web page elements such as HTML headings and text, images called with HTML tags, and any other part of the page that is unaffected by the ISML conversion process, are considered static content. 84) What is dynamic page content in SFCC?When ISML tags call variables to generate a specific list at run time (for example, a list of products), they look up object properties in the Pipeline Dictionary to present product details or other session-dependent data dynamically. This is called dynamic content. URLs are another example of dynamic content. The system parses this information at run time to compose content that changes from session to session. 85) How you can pass certain product into res.render() method to access it later in template by variable my Product?res.render(‘template_path’, {myProduct : product}). 86) What is tag used in ISML?Build units of reusable template functionality that are inserted into the template using custom ISML tags.When specifies a template, the specified template is included and user defined attributes/custom ISML tags are accessible. 87) How can you ensure that a script expression is HTML encoded?You must set the included page’s content type to text/html via the following statement: 88) What are custom hooks in SFCC?They are custom extension points which can be called in your storefront code using the B2C Commerce script System package HookMgr class methods. You can then access the hook in either OCAPI or your storefront code. This flexibility makes them useful for functionality in a multichannel set of applications based on the same site. 89) If there are multiple modules to call in one extension point, how can we control their order of execution?We can’t control the order in which the modules are called. 90) If you call multiple modules in one single hook, which value will be returned? (Let’s pretend that all modules have return statement)Only the last hook returns a value. 91) How can we manage hooks execution order?Hooks are executed in the order of the cartridges on the path. Therefore, when you change the order of the cartridges, you also change the order of hook execution. 92) Why should we be cautious when using hooks? Because unprivileged users can make privileged OCAPI or method calls. Also, because of the design placement of OCAPI hooks, a developer can inadvertently modify API calls to accept no authentication or to bypass expected authorization entirely. 93) What are shop API accepted request methods? GET, POST, PATCH, DELETE, PUT. 94) What are log files in SFCC?Log files capture information about system resources, performance, errors, and quotas. 95) Which roles can view SFCC logs? Site admin and developer 96) How many log levels are there in SFCC? There are 5 of them:info error warn debug fatal 97) How many custom log names can we have in SFCC?SFCC allows only 40 different log file names (therefore, 40-log instances and log files) per day. This quota is a hard limit and is counted per App server. 98) How can we identify that log is for web service?The log file name for a web service always starts with “service”. E.g., service-logprefix-blade2–4-appserver-20150206.log 99) What is security log in Salesforce B2C commerce? Security log contains log entries for Business Manager logins. 100) When security log is deleted and can we delete them manually?Security log files are automatically deleted after 90 days. Users and clients can’t delete security logs, or turn off security logging. 101) How can we get parameter with name addressId from query string in controller endpoint?req.querystring.addressId 102) How can we perform a null-check in SFCC?We can use empty(object) operator. Example: empty(addressId). 103) Which controller method should we use to overwrite the functionality? server.replace 104. How can we get complete url path when we know only controller name and endpoint ? Let it be Account-Login.We should use the URLUtils package and it’s method called url. For Account-Login it would be URLUtils.url(‘Account-Login’). 105. How can we get the form with name newsletter which is stored under cartridge/forms directory with file name newsletter.xml ?If we have required server package, it is very simple to do that, just with following code: var newsletterForm = server.forms.getForm(‘newsletter’) 106. What is the difference between Resourse.msg() and Resource.msgf() methods?Resource.msg — Returns the message from the specified properties resource bundle.Resource.msgf — Returns the message from the specified properties resource bundle, with the provided arguments substituted for the message argument placeholders 107. How can we generate csrf token in our controller?We should require csrf middleware and include it to our controller endpoint middleware (between enpoint name and the endpoint function declaration. 108. How can we declare and set server variables in template? There are 2 ways to achieve that:1) write server script inside the tag and use js syntax for variable declaration and setting 2) Use the ISML tag, which populates the variable with provided data (value and scope) 109. How can we figure out is service mocked or not in code? Check the value returned from service.isMock(). 110. How can we prevent changes in object?We should use Object.freeze() method passing the object as parameter. 111. How can we check that new properties can be added to an object?We should use Object.isExtensible() method passing the object as parameter. 112. How can we get an array of object properties names?We should use Object.keys() method passing the object as parameter. 113. How can we escape/unescape URI special characters?We should use decodeURI static method to unascape characters, and encodeURI static method to escape them. 114. How can we hide the part of the page from unregistered customers?In template, we should add conditional tag with condition similar to session.customer.isRegistered, and place the markup you want to hide between opening and closing tags. 115. When can we use Transaction.rollback() method?We can use that method only if transaction was started with with begin () before 116. What is the best practice to iterate through SFCC objects array? Require collections module, which can be found under scripts/util directory 117. Why do we need layout folder in templates directory? It is common place to store page decorators. 118. Why do we need tag?The decorator template uses tag to identify where the decorated content is to be included. 119. What happens if the decorator has multiple tags? If the decorator template has multiple tags, the content to be decorated is included for each tag. 120. Which class should be used for creating a server instance in SFCC? Local Service Registry. 121.

How can we get site default locale? dw.system.Site.getCurrent().defaultLocale. 125. What is the difference between Array.prototype.map() and Array.prototype.forEach()?The main difference between map and forEach is that the map method returns a new array by applying the callback function on each element of an array, while the forEach method doesn’t return anything. 126. What is the difference between inline, inline-block, and block elements?The block elements always start on a new line. They will also take space for an entire row or width. List of block elements are , .Inline elements don’t start on a new line, they appear on the same line as the content and tags beside them. Some examples of inline elements are , ,, and tags.Inline-block elements are similar to inline elements, except they can have padding and margins and set height and width values. 127. Considering the following JavaScript object: let bike = {gears: 10}.

In other words, it explains how transparent the element is. 130. How can image repetition of the background image be controlled?background-repeat property controls the repetition of images in the background. Use no-repeat if the image is to be displayed once in the background (background- repeat: no-repeat;). 131. What is Cascading in CSS?Cascading determines what rules to apply to elements by sizing up the importance of various styling rules that may be in conflict with each other. 132. Is css case-sensitive?CSS is not case-sensitive, but the URLs of images and font families are case- sensitive. CSS is case-sensitive only for XML declarations with XHTML DOCTYPE on the page. 133. What is the universal selector?Universal selector (*) is a selector which can match the name of any element type, rather than selecting the elements of a specific category. 134. What are the key features of jQuery?DOM Manipulation, Event handling, AJAX Support, Animations, Lightweight, Cross Browser Support. 135. What is the difference between $(this) and this in jQuery ? this and $(this) refer to the same element but the difference is that this is used in a traditional method but with $() it becomes a jQuery object on which we can use the functions of jQuery. 136. What are the three required parameters used for the jQuery Ajax method?1) URL — You need to specify the URL to send the request;2) Type — This specifies the type of requests such as Get or Post;3) Data — It specifies the data to be sent to the server; 137. What is method chaining in jQuery and what are the advantages?Method chaining is a feature of jQuery that allows several methods to be executed on a jQuery selection in sequence in a single code statement.For example:$(‘button#play-movie’) .on(‘click’, playMovie).css(‘background-color’, ‘red’) .show() 138. What is the usage of html() method in jQuery?The jQuery html() method is used to change the entire content of the selected elements. It replaces the selected element HTML content with new content. Do not muddle with .text() method 139. What must have files to implement page or component types in page designer?To implement page types and component types, you must include a meta definition file and a script file. 140. Where do we define page-level custom attributes for page designer?The page-level attributes should be defined in the meta definition file for the page type. 141. How can we optimize page loading time?There are numerous things accountable for lowering page load time. Let us look at the four best ways to reduce its loading time:Image Optimization: It is always advised to scale your videos and pictures before uploading them to a page.Browser Cache: The utilization of cache will boost speed for pages that you have visited already. Optimize and compress content: Compressing the content of a website decreases the load time of a page to a great extent.Stylesheet Reference on Top: Setting stylesheet reference to the header of a doc allows your page to load quickly. 142. What is Progressive Rendering?Progressive rendering is a process that is utilized generally to boost the web page’s rendering content process. Now the rendering process is utilized in modern web development to enhance the mobile data uses of the user, async HTML fragments, prioritizing visible content, and lazy loading of images. 143. Why do we utilize the “use strict”; statement?The ‘use strict’ statement sets a few restrictions in the script. Typically, it is utilized to facilitate the strict mode of the script, making sure there could be no loose coupling like undeclared variables. 144. Define the Anonymous function in JS?Generally, the function name is defined when we define the function itself, in normal user-defined functions, but in the case of an anonymous function, the function name is not defined. Here we make use of an assignment operator and variable to stow the function as an object, then utilizing that variable, we will be capable to invoke the function itself.Example: var multiply = function(a,b){ return a*b ;} 145. Suggest some ways on how to fix the browser-specific styling issue?We can make a distinctive stylesheet for various browsers making use of server-side rendering. Another method is utilizing a library such as Bootstrap, which already has the code to manage the browser-specific styling issue.Reset or Normalize CSS can also be utilized. Multiple 3rd party plugins equip libraries for browser styling issues. 146. What is the difference between attribute and property? Attributes are an element of an HTML document while properties are a part of the Document Object Model (DOM).Example: Here, value and type are the attributes of HTML, but when the statement is read by the browser and parses this code it will make a DOM with different properties, like accept, autofocus, accessKey, baseURI, checked, childElementCount, align, alt, childNodes, children, classList, className, attributes, and clientHeight.Example:var data = document.querySelector(input); // here we created a document object of input tagconsole.log(input.getAttribute('value')); // tech // getting the attribute value console.log(input.value); // tech // getting the property of the input object 147. Why did we utilize the data- the attribute in HTML and why it is now advised not to use?Generally, data attributes of HTML are utilized to accumulate the custom data, which is private to the web application or page. This custom data is for personalizing the JavaScript of the user as per the user action on the web page. These days, data-attributes are not advised to utilize as the user can change the attribute easily just by utilizing the browser inspect console. 148. What is the difference between classical inheritance and prototypal inheritance?Class Inheritance: instances inherit from classes (like a blueprint — a description of the class), and create sub-class relationships: hierarchical class taxonomies. Instances are typically instantiated via constructor functions with the `new` keyword. Class inheritance may or may not use the `class` keyword from ES6.Prototypal Inheritance: instances inherit directly from other objects. Instances are typically instantiated via factory functions or `Object.create()`. Instances may be composed from many different objects, allowing for easy selective inheritance. 149. What are pseudo-elements? Pseudo-elements are keywords that let you specify specific parts of an element instead of the entire thing. For example, you can select an element’s ::first-line or select ::before an element. 150. What is the purpose of OCAPI ?The Open Commerce API (OCAPI) enables you to access resources using HTTP requests and HTTP responses. Each resource is addressed by its unique URL, which includes the API version. Data is transported using request or header parameters, or within the request body as a JSON document with a defined structure. OCAPI is divided into different APIs: the Shop API allows a client to interact with the system as a shop customer or as an agent shopping on behalf of a customer, the Data API gives create/read/update/delete access to system resources, and the Meta API is used to retrieve a formal description of the Open Commerce API, including custom attributes. 151. What are the key differences between OCAPI requests and storefront-based pipeline or controller requests?There are several fundamental differences between OCAPI and pipeline / controller- based requests that should be considered by developers when designing an OCAPI strategy for API-first applications:1) OCAPI requests are not cached by the web-tier, they are cached with a separate cache that is owned by the application-tier — which follows the same cache-clear behavior as the web-tier;2) OCAPI requests always incur application-tier overhead — regardless of their cache status. Since OCAPI requests are not cached by the web-tier, they always incur the overhead associated with uncached storefront requests;3) OCAPI documents follow a different caching behavior than storefront requests. Where storefront requests will respect the individual cache TTLs of remote-include content, OCAPI requests that comprise multiple documents will respect the minimum cache TTL of all documents retrieved from the request. 152. Can OCAPI Data API requests be cached by Salesforce B2C Commerce ?No. Due to the nature of OCAPI Data API requests, they cannot be cached. All Data API requests will incur real-time processing via the application-tier to retrieve the data requested, format it as part of the REST API response, and deliver the response. 153.
