Question 1
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?
A. 1. Use console at /system/console/crypto to encrypt the value 2. Either create an encrypted value for each AEM instance and use runmodes to apply the different values or make sure relevant instances share the same master key 3. When loading the value in the code, call CryptoSupport.unprotect(_) before using the value
B. 1. Use console at /system/console/configMgr and tick the checkbox "encrypt" before saving a configuration 2. Use encrypted values work across all instances 3. When loading the value in the code, call CryptoSupport.unprotect(...) before using the value
C. 1. Use console at /system/console/crypto to encrypt the value 2. Either create an encrypted value for each AEM instance and use runmodes to apply the different values or make sure relevant instances share the same master key 3. Sensitive information is automatically decrypted using the CryptoSupport OSGi service before the value is returned
D. 1. Use console at /system/console/configMgr and tick the checkbox "encrypt" before saving a configuration 2. Either create an encrypted value for each AEM instance and use runmodes to apply the different values or make sure relevant instances share the same master key 3.

Question 3
A developer needs to implement a header component for a website. The component has the following requirements: - The component should be configured once on the page highest in the hierarchy. - The header component on pages lower in the hierarchy should look the same and show the same data. - If necessary, the configuration can be overwritten on a child page. - The component should show a list of links that are configured in the header component. Which code snippet for returning the list of pages should the developer use?
A. "public String[] getHeaderLinks(Page page) { final Resource pageContent = page.getContentResource(); final ComponentInheritanceValueMap properties = ComponentInheritanceValueMap(pageContent); return properties.get(HEADER_PAGE_LIST, String[].class); }"
B. "public String[] getHeaderLinks(Resource componentResource) { final ComponentInheritanceValueMap properties = componentResource.adaptTo(ComponentInheritanceValueMap.class); return properties.getInherited(HEADER_PAGE_LIST, String[].class); }"
C. "public String[] getHeaderLinks(Resource componentResource) { final HierarchyNodeInheritanceValueMap properties = new HierarchyNodeInheritanceValueMap (componentResource); return properties.getInherited(HEADER_PAGE_LIST, String[].class); }"
D. "public String[] getHeaderLinks(Resource componentResource) { final HierarchyNodeInheritanceVauleMap properties = componentResource.adaptTo(HierarchyNodeInheritanceVauleMap.class); return properties.getInherited(HEADER_PAGE_LIST, String[].class); }"
