Advance Interview Questions Part 5
Here I will try to put new AEM 6.3+ version questions being asked in Interviews.
How jenkins know that the sonar has failed?
A : By using quality gates as post build action after every jenkins job, will ensure the jenkins build fails when quality (i.e. coverage or number of bugs etc) is not matched in sonarqube build.
How to inherit client libs from parent to child with child having it's own values?
A : Embed the global clientlibs category and override the required classes and js in your clientlibs.
How to ensure the assets are shared and used by different authors and publishers from one location in AEM?
A : For this scenario, using Asset as cloud service is the best and latest solution. However older versions of AEM also supported binary less assets replication for this purpose.
Core component - Image component out of the box lazy loading.
A : Image component has out of the box lazy loading feature as part of component policy (design dialog).
Why content as service is required by AEM?
A: You need content to go anywhere and everywhere — screens, websites, mobile apps, IoT devices and beyond. But you don’t have the time to recreate that content for all those channels yourself. What it all comes down to is that you need content that works no matter what device they use, but you need it without all the heavy manual programming.
Content as a service lets you use any of your content in Experience Manager and delivering that content to any channel. You can set the content for delivery to different types of devices with just a few keystrokes. And your developers don’t need deep knowledge of the Experience Manager repository structure. Select how you want the content delivered — as packed HTML (HTML/CSS/JS) or channel-independent content (JSON). Now, you can easily manage content and experiences for your digital properties, viewing and changing content in real time.
What is the benefit of using language copy?
A : If you do wish to translate content, then please evaluate using Language Copy instead of live copy. Language Copies can be updated as well and synchronized with their source. AEM has Update & Translate workflows available Out of the box that can synchronize changes between the source and language copy. However, in order to use these workflows, one needs to structure the content in a way that language roots (pages with ISO locale code) are all at the same level.
What is shallow live copy?
A : Switching to a shallow live copy: Will have immediate effect and is non-reversible.
- Child pages are explicitly detached from the live copy. Further modifications on children cannot be preserved if undone.
- Will remove any descendant LiveRelationships even if there are nested LiveCopies.
Translation project in detail.
A : Translation projects enable you to manage the translation of AEM content. A translation project is a type of AEM project that contains resources that are to be translated into other languages. These resources are the pages and assets of the language copies that are created from the language master.
Third party integration with hybris.
A:
1. Use Adobe's package share to install cq-hybris-server, cq-hybris-content, cq-geometrixx-hybris-content.
2. If you have cq-hybris-server package installed, Platform will start automatically along with AEM. You do not have to do anything more as it is already pre-configured and works out of the box. This will connect with your local hybris instance.
3. If you have to connect with a standalone ecomm server, do following
- Go to http://localhost:4502/system/console/configMgr.
- Search for Day CQ Commerce Hybris Connection Handler and click on it.
- Now, change Base URL variable in the popup.
- You can also change other values if required.
- Test integration by importing the catalog from the Platform: http://localhost:4502/etc/importers/hybris.html.
What is cross channel and omni channel marketing?
A : Cross-channel marketing is a strategic, customer-focused digital marketing technique used by marketers globally to provide their customers with a consistent experience when interacting with their brand across multiple digital channels
Omnichannel marketing refers to the multichannel sales approach that provides the customer with an integrated shopping experience. The customer can be shopping online from a desktop or mobile device, via phone, or in a brick-and-mortar store, and the experience will be seamless
How to make sure only a part of page is dynamic in akamai (CDN) in case we're not using dispatcher or SDI?
A : most of the CDN are capable of supporting ESI, which is Edge Side Include. This is same as Apache's Server Side Include, which facilitates, only some part of the page be fetched dynamically and other static part of the page remains cached.
Content with an ESI tag is fetched from somewhere else, while the rest of the webpage's content can be cached. If only some of the webpage is generated dynamically and the rest is cached, the webpage will load much more quickly than if the whole page needed to be generated for each user.
What is the reason for using Dynamic media?
Dynamic media is a content as service offering from Adobe. Dynamic media provides with some unique AI based features to assets in AEM like smart tagging, smart crop, interactive images etc. Dynamic media images can be accessed through AEM instances and can be configured to give dynamic digital experiences to the consumers. There are plenty of URL modifiers can be used those can be used with assets to get dynamic rendering of the images/videos. This is useful when there are large assets involved and those require dynamic modification on the fly.
Explain shared DAM in AEM 6.5.
Shared DAM or connected DAM is a feature offered by AEM to provide integration of AEM sites and Assets. At times the website creation capabilities and digital assets used to create these websites may reside in different deployments. One reason can be geographically distributed existing deployments that are required to work together. Another reason can be acquisitions leading to heterogenous infrastructure, including different Experience Manager versions, that the parent company wants to use together.
Explain the process of using S3 bucket to store assets.
AEM can be configured with S3 bucket allowing assets binary data to be stored on S3 bucket. There are two ways of using S3 bucket for storing assets.
1. Clustered
2. Stand alone
A special feature pack is required to be installed in AEM, Once the necessary configuration changes have been made and AEM is started it will automatically start syncing all its binary data to the S3 storage bucket.
Download the S3 bucket related jar from here - https://repo1.maven.org/maven2/com/adobe/granite/com.adobe.granite.oak.s3connector/
and then go to \jcr_root\libs\system\install and copy all the jar files and keep it inside crx_quickstart/system/install directory of your local instance of AEM. Restart the AEM. This should install required connector for S3 bucket in you environment.
S3 bucket can easily handle 100 requests per second.
Each asset is stored as a separate entry.
When storage size runs into the terabyte range a clustered S3 architecture can be useful. Instead of having 3 buckets for 3 servers with a total of 15 TB it is also possible to share a single bucket.
When storage size runs into the terabyte range a clustered S3 architecture becomes interesting: instead of having 3 buckets for 3 servers with a total of 15 TB it is also possible to share a single bucket. Finally, as a rule of thumb: if total size equals or exceeds 500 GB a move to S3 is advisable. Similarly, if the repository is expected to grow larger than 500 GB or its growth cannot easily be accommodated on the current hosting platform than a move to S3 is also suggested.
Provide details of ams services.
Adobe Managed Services, or AMS, is a Cloud-based management service bringing Adobe Experience Cloud products (including Analytics, Campaign, Target and Experience Manager) closer to Software as a Service (SAAS) solutions. To create powerful digital experiences, you need agility, speed and security.
AMS gives automated capabilities like CI/CD pipelines based on cloud manager. It is secure, scalable and provides high availability.
