        質問 # 20
        What should the packageType be for immutable code packages in a Maven project structure?

        正解:C

        解説:
        Comprehensive Explanation
        Adobe Experience Manager as a Cloud Service separates application code from mutable repository content through a defined content-package architecture.
        Immutable code packages must declare their package type as application . This designation identifies packages containing application definitions, components, configuration resources, and other code-related repository structures.
        The property is configured within the FileVault Package Maven Plugin configuration:
        < packageType > application < /packageType >
        In a typical AEM Project Archetype implementation, the ui.apps module contains immutable application resources under /apps , while the ui.content module contains mutable content resources.
        Option B is incorrect because content identifies packages containing mutable repository content, commonly associated with paths such as /content and /conf .
        Option C is incorrect because container packages organize and distribute other packages. The corresponding container package generally acts as an aggregation mechanism rather than representing an individual immutable application package.
        This separation is particularly important in AEM as a Cloud Service because application code is deployed through Cloud Manager pipelines using an immutable infrastructure model.
        Adobe explicitly requires code packages to use the application package type, while mutable content packages use content .

        質問 # 21
        A developer finds that Dispatcher is not permitting query parameters.
        Which Dispatcher configuration section should the developer review to resolve the issue?

        正解:C

        解説:
        Comprehensive Explanation
        Adobe Experience Manager Dispatcher controls external HTTP request access through the /filter section of its farm configuration. This section can permit or reject requests according to their HTTP method, URL, selectors, extensions, and query strings.
        When Dispatcher rejects a request containing query parameters, the developer should inspect its access-filter rules to determine whether an appropriate /query condition has been configured.
        For example:
        /filter {
        /0001 {
        /type "allow"
        /method "GET"
        /url "/content/site/*"
        /query "q=*"
        }
        }
        This rule permits matching GET requests containing the designated query parameter.
        Option A controls the AEM rendering instances and does not determine whether query strings are permitted.
        Option B generally refers to cache rules, which govern cache eligibility. Option C controls caching behavior, including /ignoreUrlParams , rather than request authorization.
        Technical qualification: The actual Dispatcher configuration directive is /filter , not /filters . Therefore, option D contains a naming error.
        Additionally, if the problem concerns pages with query parameters bypassing the cache rather than being rejected, option C would be relevant because /cache/ignoreUrlParams controls query-parameter caching behavior.
        For requests being denied, D identifies the intended configuration area.
        Official Adobe Reference: Configure Dispatcher - Restrict Query Strings and Ignore URL Parameters.


        質問 # 22
        What steps should a developer take to create a custom Oak index in AEM?

        正解:B

        解説:
        Comprehensive Explanation
        Adobe Experience Manager uses Apache Jackrabbit Oak as its underlying content repository. Oak provides query indexes to optimize access to repository content without requiring expensive traversal operations.
        A custom Oak index is defined through an index definition under the /oak:index repository hierarchy. The definition identifies the index type, indexed node types, relevant properties, and additional indexing behavior.
        For Lucene indexes, the definition typically uses jcr:primaryType set to oak:QueryIndexDefinition , type set to lucene , and an appropriate asynchronous indexing configuration.
        Option D correctly identifies the fundamental process of defining a custom Oak index.
        Option A is incorrect because Sling servlets handle HTTP requests rather than establishing native Oak repository indexes.
        Option B is incorrect because writing a Query Builder query does not automatically create the necessary custom index.
        Option C is incorrect because Dispatcher manages HTTP request caching and filtering, not repository-level Oak indexing.
        Cloud Service qualification: Adobe recommends maintaining custom index definitions in the application codebase and deploying them through Cloud Manager. Production developers should not manually create or modify index nodes through CRXDE Lite.
        For AEM as a Cloud Service, index definitions are generally maintained under the project's _oak_index directory using versioned index names.

        質問 # 23
        What is the out-of-the-box Dispatcher response when a request is made for a URL defined as deny in the Dispatcher /filter setting?

        正解:A

        解説:
        Comprehensive Explanation
        Adobe Experience Manager Dispatcher provides request-level security filtering through the /filter section of its configuration. This mechanism determines which incoming HTTP requests are permitted to reach an AEM rendering instance.
        When an incoming request matches a rule explicitly configured with /type "deny" , Dispatcher rejects the request and returns an HTTP 404 Not Found response.
        The response is intentionally different from the HTTP 403 Forbidden status commonly associated with authorization failures. Dispatcher filtering operates as an access-control layer that can prevent external clients from discovering restricted repository endpoints.
        For example:
        /filter {
        /0001 { /type "deny" /url "*" }
        /0002 { /type "allow" /url "/content/*" }
        }
        This configuration denies requests by default and permits requests matching the specified content path.
        Option B is incorrect for the documented default response to a denied Dispatcher filter request. HTTP 403 can occur in other authorization or security contexts, but it is not the expected filter-denial response here.
        Option C indicates a malformed client request and is unrelated to the normal Dispatcher filtering behavior.
        Adobe explicitly documents the 404 response for requests rejected through Dispatcher filter rules.
        Official Adobe Reference: Configure AEM Dispatcher - Configure Access to Content, Example Filter: Deny All.


        質問 # 24
        A developer wants to view response times for page transactions.
        Which log file should they use?

        正解:C

        解説:
        Comprehensive Explanation
        Adobe Experience Manager maintains an HTTP request log that records incoming requests and their corresponding responses, including response times.
        The request.log file is particularly useful for identifying slow page requests, diagnosing performance problems, and evaluating application responsiveness.
        Each request receives an identifier that associates the incoming HTTP request with its corresponding response. The response record includes the HTTP status code, content type, and processing time.
        For example:
        09:43:41 [66] - > GET /content/site/en.html HTTP/1.1
        09:43:41 [66] < - 200 text/html 797ms
        In this example, AEM required 797 milliseconds to process the request.
        Option A is incorrect because audit.log primarily records auditing information, such as content-related administrative and moderation activities.
        Option B is incorrect because stdout.log captures standard-output messages, including startup-related information, rather than providing the dedicated request timing records.
        Option C is correct because request.log provides a direct mechanism for analyzing HTTP response times.
        Adobe recommends using request-log analysis to identify slow pages, evaluate request concurrency, and diagnose application performance bottlenecks.
        For extensive performance investigations, developers can aggregate response times by URL and correlate slow requests with thread dumps, repository query performance, and application logs.
