You are using Azure Cognitive Search and you add documents to your search index from a specific datasource. For change tracking and eventual consistency with the datasource, you plan to enable incremental enrichment. This way you will ensure the least amount of effort to track and respond to changes in your enrichment pipeline. In this process, you also enable caching on the existing indexer. Assuming that you have the indexer definition, review the JSON code snippet below and complete it by choosing the required and optional properties to modify the cache property in indexer definition. (select two answer choices) 
<pre class="brush:java;">{
"name": "&lt;Indexer Name&gt;",
"targetIndexName": "&lt;Index Name&gt;",
"dataSourceName": "&lt;Datasource Name&gt;",
"skillsetName": "&lt;Skillset name&gt;",
"cache" : {
".............................................." : "&lt;Connection String&gt;",
"..............................................": &lt;true/false&gt;
},
"fieldMappings" : [],
"outputFieldMappings": [],
"parameters": []
}
</pre> 

Answer options:

A.disableCacheReprocessingChangeDetection
B.storageConnectionString
C.enableReprocessing
D.ignoreResetRequirement

Correct Answers: B and C 
Here is the completed code snippet 
<pre class="brush:java;">{
"name": "&lt;Indexer Name&gt;",
"targetIndexName": "&lt;Index Name&gt;",
"dataSourceName": "&lt;Datasource Name&gt;",
"skillsetName": "&lt;Skillset name&gt;",
"cache" : {
"storageConnectionString" : "&lt;Storage Account Connection String&gt;",
"enableReprocessing": true
},
"fieldMappings" : [],
"outputFieldMappings": [],
"parameters": []
}
</pre>Option A is incorrect because the disableCacheReprocessingChangeDetection property is set to true when you do not want to update an existing document. This parameter is applicable to skillset.
Option B is correct because a storage account is used to retain the cache for the results of the skills updated. The parameter value uses the connection string of the storage account. This is a required parameter.
Option C is correct because enableReprocessing value is set to true for enabling incremental enrichment. If you intend to disable incremental enrichment, set this value to false.
Option D is incorrect because the ignoreResetRequirementproperty value is set to true to allow the commit without a reset condition.
