A website built on AEM Sites displays the company's stock price in the footer of all pages. The stock data is retrieved from a third party REST service using two-way SSL and rendered in an AEM component using HTL During performance testing in the last development sprint it becomes apparent that the third party service sometimes takes up to 30 seconds to respond, which degrades the overall site performance.
How should an Architect address this issue?

1. A. Call the REST service directly from the browser
2. B. Temporarily remove the component from all content
3. C. Load the stock data component asynchronously
4. D. Add a 5 second timeout to the REST call

Correct Answer: C
“loading the stock data component asynchronously can improve the site performance by not blocking the page rendering while waiting for the REST service response”.

A customer wants to migrate their AEM environment from an on-premise infrastructure to a public cloud to improve performance. The customer currently hosts many assets (images, videos, documents) in the DAM. Approximately 10 business users frequently upload new assets and update existing assets. Editors then use these assets on the sites.
What should an Architect do as part of this migration?

1. A. Move to a shared datastore and enable binary less replication
2. B. Set up Connected Assets to share the DAM assets in the sites
3. C. Set up a horizontally scalable AEM environment on MongoDB
4. D. Run online revision cleanup before moving to the new storage format

Correct Answer: D
“running online revision cleanup before moving to the new storage format can reduce the size of the repository and improve performance”.

A large digital agency has 10 TB of assets in their DAM where renditions for each Asset must be created without affecting performance for the authors. Which capability should the Architect recommend to meet the requirements?

1. A. Reduce the number of AEM Asset versions
2. B. Create AEM multi-threaded workflow
3. C. Use AEM Asset Offloading
4. D. Update dispatcher configuration to cache Assetsa

Correct Answer: C
“AEM Asset Offloading allows for delegating asset processing tasks such as rendition generation to a separate AEM instance or service. This reduces the load on the author servers and improves performance for authors”.

An Architect needs to design a deployment process without downtime for end users. The system architecture contains an AEM author, two AEM publishers, two publish Dispatchers, and a centrally managed load balancer. The publishers serve some content that cannot be cached.
Which two actions should the Architect take to meet these requirements? (Choose two.)

1. A. Connect each publish Dispatcher to one AEM publish
2. B. Use each publish Dispatcher to load-balance to both AEM publishers
3. C. Deploy software packages by replicating them from author to publishers
4. D. Configure the centrally managed load balancer to connect directly to the AEM publisher that is not being dedKyed to
5. E. Deploy software package to AEM Publishers one by one

Correct Answer: BE
“using each publish Dispatcher to load-balance to both AEM publishers can provide high availability and fault tolerance. Deploying software packages to AEM Publishers one by one can avoid downtime for end users”.

An AEM Sites implementation is migrating from on-premise to AEM as a Cloud Service. Previously, the application was deployed in a single package for both code and access policy nodes. After initial deployment and testing in the new infrastructure, it is reported that user permissions are not working as expected.
What change should the Architect make to address this issue?

1. A. Update package metadata to use MergePreserve for handling access policy nodes
2. B. Move access policy nodes to a dedicated package and install manually
3. C. Refactor access policy nodes to Apache Sling JCR Repoinit scripts in the same package
4. D. Document permissions and request the Customer Success Engineer to configure

Correct Answer: C
Refactor access policy nodes to Apache Sling JCR Repoinit scripts in the same package1. According to Adobe Experience Manager documentation23, access policy nodes are used to control who can access a
policy-protected document. However, they are not supported by AEM as a Cloud Service and need to be refactored using Apache Sling JCR Repoinit scripts.
