You have created indexers in your cognitive search solution in Azure. They ran once as they were created. However, you need to run them periodically for multiple reasons. Review the statements given below regarding index scheduling and choose the true ones. [choose three statements]

Answer options:

A.Indexer execution schedule uses interval and start time properties in REST API call.
B.In the REST API call, dataSourceName and targetIndexName are optional.
C.Indexers with skillsets can be scheduled at an interval of 2 hours.
D.The execution of indexer would be postponed to the next scheduled time, if it is already running.
E.The smallest indexer schedule interval allowed is 10 minutes and the largest interval is 12 hours.

Correct Answers: A, C and D
Option A is correct because the schedule uses interval and start time properties in the REST API call. Here is a quick example:
<pre>PUT https://myservice.search.windows.net/indexers/myindexer?api-version=2020-06-30
Content-Type: application/json
api-key: admin-key
{
"dataSourceName" : "myazuresqldatasource",
"targetIndexName" : "target index name",
"schedule" : { "interval" : "PT10M", "startTime" : "2021-01-01T00:00:00Z" }
}
</pre>
Option B is incorrect because the indexer needs a datasource and target index for the scheduler to execute the indexer. Here is a quick example:
<pre>PUT https://myservice.search.windows.net/indexers/myindexer?api-version=2020-06-30
Content-Type: application/json
api-key: admin-key
{
"dataSourceName" : "myazuresqldatasource",
"targetIndexName" : "target index name",
"schedule" : { "interval" : "PT10M", "startTime" : "2021-01-01T00:00:00Z" }
}
</pre>
Option C is correct because the maximum allowed interval for indexers with skillsets is 2 hours.
Option D is correct because only one indexer run is allowed at a given time. If the indexer is already running, the next execution will be postponed till the next scheduled time.
Option E is incorrect because the minimum allowed interval for the indexer schedule is 5 minutes, and the maximum allowed interval is 1440 minutes or 24 hours.
