Question 1

ZephyrCorp's marketing team relies heavily on UTM parameters for campaign tracking. However, the IT team notices that the AEM Dispatcher is not caching any pages when users arrive via campaign links (e.g., `/content/zephyr/home.html?utm_campaign=summer`). Which configuration must the developer adjust to ensure the page is cached while still passing the parameters to the client-side analytics?

Accepted Answer

Add the UTM parameters to the /ignoreUrlParams section with an 'allow' rule.

Answer

Add the UTM parameters to the /filter section with a 'deny' rule.

Answer

Configure the /cache section to set /allowAuthorized to '1'.

Answer

Update the /statfileslevel configuration to match the depth of the campaign pages.

Question 2

A content author at Nimbus Retail modifies the 'Hero Image' component directly on a Live Copy page located at `/content/nimbus/us/en/home`. What is the immediate effect of this action on the Multi-Site Manager (MSM) relationship?

Accepted Answer

Inheritance from the Blueprint is cancelled specifically for the 'Hero Image' component.

Answer

The Live Copy relationship is permanently detached for the entire page.

Answer

The changes are automatically pushed back to the Blueprint.

Answer

The modification is rejected unless the author explicitly suspends the Live Copy first.

Question 3

True or False: When resolving OSGi configurations, a configuration placed in the `config.author.dev` folder will take precedence over a configuration placed in the `config.author` folder for an AEM instance running with the run modes `author` and `dev`.

Accepted Answer

True

Answer

False

Question 4

Quantum Financial is experiencing severe performance degradation when executing a JCR-SQL2 query that searches for all 'cq:Page' nodes containing the word 'mortgage' under the path '/content/quantum/en', while also filtering by a custom property 'jcr:content/approved=true'.

As the lead AEM Developer, you need to optimize this query by creating a custom Oak index. Based on the requirements, which index type is the most appropriate and why?

```mermaid
flowchart TD
A[Query Execution] --> B{Contains Full-Text Search?}
B -- Yes --> C[Lucene Index]
B -- No --> D{Property Restrictions Only?}
D -- Yes --> E[Property Index]
D -- No --> F[Traversal]
```

Accepted Answer

A Lucene Index, because the query involves a full-text search ('contains the word mortgage') which Property Indices do not support efficiently.

Answer

A Property Index, because filtering by the custom property 'approved=true' is faster using an exact match evaluation.

Answer

An Ordered Index, because the results must be evaluated sequentially based on the path depth of '/content/quantum/en'.

Answer

A Node Type Index, because the query specifically filters for nodes of type 'cq:Page'.
