A developer needs to use the AEM Core Components. What is the recommended way to complete this task?
The recommended approach to use AEM Core Components is by creating proxy components. Proxy components are essentially wrapper components within your own project that reference the core components. This practice allows developers to inherit functionality from the core components while being able to override and extend it as necessary. By using proxy components, developers can ensure that any custom styles and configurations are preserved even when the core components are updated in the future.
A developer wants to replace the element name of the host element with titleLevel property of the model in HTL.
Which action would be taken to complete this task?
In HTL (HTML Template Language), data-sly-element is used to dynamically set the name of a DOM element. The provided option C correctly demonstrates the use of data-sly-element to replace the element name with the value of the titleLevel property of the model. The context 'unsafe' is specified because changing the element name can be a security risk if the value is not properly sanitized since it could lead to script injection vulnerabilities if used with user-provided data.
Options A and B are incorrect because they don't use the data-sly-element attribute, which is necessary to dynamically change the tag name of the element in HTL.
A developer wants to be able to execute the following query:
SELECT
*
FROM [ntbase] AS s
WHERE
s.status ='STARTED'
Which two options are mandatory additions to the Index? (Choose two.)
When creating a custom query in AEM's JCR (Java Content Repository), the query's performance is highly dependent on the indexing configuration. For the given query that selects all nodes with a 'status' property equal to 'STARTED' from the 'nt:base' node type, the index must be set up correctly:
Option A, 'nt:base index rule', is correct. The index rule for 'nt:base' must be added to define which properties of nodes of this type are indexed.
Option D, 'status property with propertyIndex = true', is also correct. This index ensures that queries filtering on the 'status' property are executed efficiently. The property index should be set to true, which means that this property is indexed and the query will use this index to filter the results.
Option B is incorrect because setting the property index to false would mean that the property is not indexed, making the query less efficient since the repository would need to scan each node to find matches.
Option C, 'nt:base aggregate', is not mandatory. Aggregates are used to include properties of related nodes in the index, but they are not required for a simple property match like the one in the given query.
A developer would like to view page transaction response times. Which log file would they use?
The request log in AEM records details about requests processed by the AEM instance, including transaction response times. This log is useful for developers when they need to analyze the performance of page requests, including how long each page takes to load. The request log can typically be found in the logs directory of the AEM installation and may be named request.log.
stdout.log typically contains the standard output of the AEM process and is not specific to request transactions.
audit.log is used to log user actions for auditing purposes and does not include transaction response times.
Which datastore is useful when the datastore is on Network File System (NFS}?
When using a Network File System (NFS) for AEM, CachingFileDataStore is recommended because it caches binary data on the file system and stores only references to the binaries in the repository. This can be beneficial for performance, as it reduces the latency associated with reading binaries over the network, especially when NFS is being used. The caching layer helps in optimizing read operations by keeping a local cache of frequently accessed data.
S3DataStore is used when integrating with Amazon S3 for storage.
FileDataStore does not provide caching capabilities and would not be as efficient as CachingFileDataStore when using NFS.
