EMT Practice Test

1. Question Content...

---

Question1: A developer has a component named foobar with the following file:
foobar.html:
<div data-one="${'foo'}" data-two="${2}" data-three="${true}"></div>
<div data-one="${''}" data-two="${0}" data-three="${false}"></div>
What is the output when the component is rendered?

Question2: An application contains an OSGi configuration that contains a password.
How should a developer prevent this sensitive information from being stored in plain text in JCR?

Question3: A developer creates an AEM editable template that includes a Layout Container. When the developer creates a page using this template, the Layout Container placeholder does NOT appear.
What is causing this issue?

Question4: A developer needs to ensure that the path /content/<proj>/segments exists on all environments with the correct initial content that the developer provides in a package. Content that exists in that path should NOT be affected.
Which import mode should the developer use in the filter definition?

Question5: A developer needs to implement a service component that should be manually configured by operations to react on operational circumstances. The service component should NOT be active by default. The service has the properties myservice.name (one string value) and myservice.stringValues (a list of the string values) to be configured.
The developer needs to use OSGi Metatype annotations to make those properties configurable in the Apache Felix Web Console.
Which set of steps should the developer take to meet these requirements?

Question6: Which two methods could a developer use to obtain a Session without using a deprecated API? (Choose two.)

Question7: A developer is installing a content package with the package manager. The developer needs to restrict the approximate number of nodes in a batch that is saved to persistent storage in one transaction.
How should the developer modify the number of transient nodes to be triggered until automatic saving?

Question8: A developer needs to install a content package on an AEM environment. However a content package with the same name is already installed.
What would be the safest way for the developer to install the content package to make sure only the changes of the new content package get applied?

Question9: A developer needs to create an OSGi service to run on an Author instance and send out newsletters at periodic intervals. Intervals should be customized using the Web Console Configuration. Concurrent execution must be prevented.
Which code snippet should a developer use to achieve?

Question10: A developer is working on a complex project with multiple bundles. One bundle provides an OSGi service for other bundles.
Which two options are necessary to ensure that the other bundles can reference that OSGi service? (Choose two.)

Question11: A developer wants to extend AEM Core Components to create a custom Carousel Component.
How should the developer extend the Core Components?

Question12: A developer has a component named foobar with the following file:
FooBar.java
import com.adobe.cq.sightly.WCMUsePojo;
public class FooBar extends WCMUsePojo; {
@Override
public void activate() throws Exception {}
public String getLink() {
return "http://www.foo'bar.com";
}
public String getText() {
return "foo'bar";
}
}
foobar.html
<div data-sly-use.fooBar="FooBar">
<a href="${fooBar.link}" title="${fooBar.text}">
${fooBar.text}
</a>
</div>
What is the output when the component is rendered?

Question13: A developer is working on the following Sling Model that is being used in a component.
@Model(adaptables = SlingHttpServletRequest.class, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL) public class SampleModel {
@Inject
private Page currentPage;
private boolead matchingTitle;
@PostConstruct
private void init(){
matchingTitle = title.equals(currentPage.getName());
}
public boolean isMatchingTitle(){
return matchingTitle;
}
}
The model must check if the configured value of the jct:title property for the component matches the same name of the current page. If the jcr:title property of the component has NOT been configured, then isMatchingTitle() must return false.
How should the developer inject the title property in this model?

Question14: A developer creates two custom classes. ClassA has the following code:
package com.aem.abc;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class ClassA {
private static final Logger logger = LoggerFactory.getLogger(this.getClass()); public void classAMethod() { logger.debug("Message from Class A method");
}
}
The developer creates a custom log custom.log with debug level in OSGi sling log support for the Java package com.aem.abc. The developer adds another class ClassB with the following code:
package com.aem.xyz;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class ClassB {
private static final Logger logger = LoggerFactory.getLogger(this.getClass()); public void classBMethod() { logger.debug("Message from Class B method");
}
}
Which action must the developer take to see the log messages in the same file from both classes?

Question15: How should a developer enable remote debugging of an AEM server without modifying the AEM start script?

Question16: A developer needs to configure sets of values according to the following parameters:
- Varies for different staging environments
- Varies for different content paths
- Diffets between author and publish
Which implementation strategy should the developer use to meet these requirements?

Question17: A developer created an editable template with a Layout Container. The developer needs to restrict the Layout Container to just one column layout.
What should the developer do to the editable template to enforce this restriction?

Question18: A banking AEM application contains functionality to calculate a mortgage rate based on user input. A servlet in place calculates the result in the backend. A call to an internal third-party REST service is required to retrieve the average object value based on a given zip code.
The following three service interfaces are used:
MortgageCalculationServlet, MortgageCalculationService and ObjectValueLookupRestService where MortgageCalculationServlet has a dependency to MortgageCalculationService and MortgageCalculationService has a dependency to ObjectValueLookupRestService.
The calculation has many combinations of input parameters and edge cases, so the JUnit coverage must be as high as possible.
Which two strategies should the developer use to ensure testability of the application code? (Choose two)

Question19: Refer to the following Client Library node structure.
+clientlibs
- jcr:primaryType="cq:ClientLibraryFolder"
- categories="[clientlibs.example]"
+ js.txt
- jcr:primaryType="nt:file"
+ css.txt
- jcr:primaryType="nt:file"
+ js
- jcr:primaryType="nt:folder"
- javascript1.js
- javascript2.js
The js.txt looks like
javascript1.js
javascript2.js
The JavaScript is NOT present in the Client Library when it is loaded.
What should a developer do to resolve this issue?

Question20: A Client-Side Library has the category "library.example".
Which HTL statement should a developer use to reference only the CSS files of this Client-Side library

Question21: From which AEM Web Console should a developer access and download full AEM Log Files?

Question22: Which log file should a developer use to search for exception stacktraces?

Question23: Two AEM publish instances feed a single Dispatcher.
Which part of the Dispatcher configuration should a developer review to ensure both AEM publish instances are used?

Question24: A custom application contains a service component com.proj.ServiceComponent. A developer needs to configure the string value name and integer value intVal. The actual configuration must be deployed using a content package.
What should the developer do to meet these requirements?

Question25: After adding new features, a developer's environment is experiencing slowness before ultimately running out of memory. The initial log analysis points towards a large number of open sessions.
Which action should the developer take to further monitor the overall session count on this AEM instance?

Question26: An application runs specific license checks against certain DAM assets every day. It should send an email to a configured list if it finds warnings, and mark the asset accordingly. A service component that uses the Apache Sling Scheduler Service is created. DAM assets that must NOT be used anymore are hidden using ACLs and the license check must re-check them.
How should a developer obtain a resource resolver that can read and update the DAM assets?

Question27: A developer is creating a custom component on the page /latestBlogs.html that needs to list all the titles of the blogs pages under /content/blogs.
How does this component get the list of child pages?

Question28: A developer is creating a custom method. This method must return a String property y from child x. the method must use only Sling APIs.
How should the developer retrieve property y of node x, and node x may or may NOT exist?

Question29: A developer is working on an HTL script for a custom component. The script has the following requirements:
* This script must list the title of every child page of the current page.
* If a child page does not have any children, then its title should link directly to that page.
* If a child page has children, then the title of every one of its children should be listed be-neath its title.
* The title of every grandchild page should link directly to that page.
Which HTL script should the developer use to meet these requirements?

Question30: One content package of a custom application contains the following content paths.

The server also contains the content path /apps/myproj/configuration that must NOT be touched when installing the package.
Which two filter definitions should a developer use to always update only the contained paths upon installation in the server? (Choose two.)

Question31: Which xml tag is used within the vault package definition to add a new path to a content package?

Question32: A service component periodically retrieves content from an external REST interface and saves the information in JCR. The REST endpoint is configured via an OSGi service property. There is one URL for production (runmode prod) and another URL for all other environments.
How should a developer configure the OSGi service?

Question33: A developer developed a workflow that makes a copy of every node created or modified under a certain path to a different one. The workflow launches but the nodes are not copied over.
Which two methods should the developer use to resolve this issue? (Choose two.)

Question34: A developer is working on a project locally and needs to install packages manually. The deployments to the localhost must be automated to speed up development. This functionality must be toggled on and off, depending on the needs of the developer.
