Which file is required in order for an AMP file to be valid?
A.
module.properties
B.
service-context.xml
C.
file-mapping.properties
D.
web.xml
Correct Answer: A
Explanation:
Option A is correct because every valid Alfresco Module Package (AMP) must contain a module.properties file. This file provides essential metadata about the module, such as its name, version, description, and unique identifier, allowing Alfresco to recognize, validate, and install the AMP correctly. Without the module.properties file, the AMP is considered invalid and cannot be deployed. The other files, such as service-context.xml, file-mapping.properties, and web.xml, may be included depending on the module's functionality, but they are not mandatory for every AMP. Therefore, the correct answer is Option A (module.properties).
Question #2 (Topic: demo questions)
Which one of the following statements about aspects is TRUE?
A.
Aspects can only be applied to “cm:content”.
B.
An aspect can have a type as a parent.
C.
An aspect may not include associations.
D.
Aspects can inherit from other aspects.
Correct Answer: B
Explanation:
Option B is correct because, in Alfresco's content model, an aspect can have a type as its parent. This allows the aspect to inherit the properties and behavior of the parent type, making it possible to extend existing content models without creating entirely new types. Aspects are used to add optional metadata and functionality to nodes and are not limited to the cm:content type. They can also include associations when required. Therefore, the statement that an aspect can have a type as a parent is true, making Option B the correct answer.
Question #3 (Topic: demo questions)
What does it mean when it is said in Solr indexing that the index is “eventually consistent”?
A.
The index will only be consistent after a server restart.
B.
The index will become consistent when there are no more transactions to index.
C.
The index becomes consistent once a day when the index job runs.
D.
The index can only be consistent when the Lucene index job eventually runs.
Correct Answer: B
Explanation:
Option B is correct because, in Solr indexing, "eventual consistency" means that the search index may not immediately reflect the latest changes made to the Alfresco repository, as transactions are indexed asynchronously. However, once all pending transactions have been processed and there are no more transactions waiting to be indexed, the Solr index becomes fully consistent with the repository. This approach improves system performance while ensuring that the index eventually catches up with all repository updates. Therefore, the correct answer is Option B: the index will become consistent when there are no more transactions to index.
Question #4 (Topic: demo questions)
When testing an Alfresco Content Services extension under high levels of concurrency, you notice
that some transactions are failing due to locking issues with the database. What is an appropriate
way to resolve this?
A.
Manually unlock the offending records and start the testing again.
B.
Directly use Alfresco’s database connection pool and write your own SQL.
C.
Use the RetryingTransactionHelper to retry code that fails due to locking.
D.
Rewrite the queries used by your application to reduce the chance of the lock.
Correct Answer: C
Explanation:
Option C is correct because Alfresco provides the RetryingTransactionHelper specifically to handle transaction failures caused by temporary database locking or deadlock issues under high concurrency. When a transaction fails due to a transient locking conflict, this helper automatically retries the transaction, improving reliability without requiring manual intervention. This is the recommended best practice for developing Alfresco extensions that must operate correctly in concurrent environments. In contrast, manually unlocking records (Option A) is not a practical or recommended solution, directly writing SQL using Alfresco's database connection pool (Option B) bypasses Alfresco's transaction management, and simply rewriting queries (Option D) may reduce locking but does not address transient transaction failures. Therefore, the correct answer is Option C.
Question #5 (Topic: demo questions)
Ifan object is moved to a different folder, what will happen to the node’s security permissions?
A.
It will inherit the ACL from the new parent folder.
B.
It will inherit the ACL from the user who is moving it.
C.
It will inherit the system wide ACL.
D.
It will keep its old ACL.
Correct Answer: A
Explanation:
Option A is correct because, by default, when an object (node) is moved to a different folder in Alfresco Content Services, it inherits the Access Control List (ACL) from its new parent folder. This means the node adopts the security permissions of its new location unless it has explicitly assigned permissions that disable inheritance. Inheritance of permissions ensures that access rights remain consistent with the folder structure and organizational security policies. The node does not inherit permissions from the user performing the move or the system-wide ACL, nor does it automatically retain its old ACL after being moved. Therefore, the correct answer is Option A.
