The correct answer is C. Distributed search is the feature that allows search heads in a company’s

European offices to search data in their New York offices. Distributed search also enables restricting

access to certain indexers by using the splunk_server field or the server.conf file1.

Distributed search is a way to scale your Splunk deployment by separating the search management

and presentation layer from the indexing and search retrieval layer. With distributed search, a Splunk

instance called a search head sends search requests to a group of indexers, or search peers, which

perform the actual searches on their indexes. The search head then merges the results back to the

user2.

Distributed search has several use cases, such as horizontal scaling, access control, and managing

geo-dispersed data. For example, users in different offices can search data across the enterprise or

only in their local area, depending on their needs and permissions2.

The other options are incorrect because:

A . Indexer clustering is a feature that replicates data across a group of indexers to ensure data

availability and recovery. Indexer clustering does not directly affect distributed search, although

search heads can be configured to search across an indexer cluster3.

B . LDAP control is a feature that allows Splunk to integrate with an external LDAP directory service

for user authentication and role mapping. LDAP control does not affect distributed search, although

it can be used to manage user access to data and searches.

D . Search head clustering is a feature that distributes the search workload across a group of search

heads that share resources, configurations, and jobs. Search head clustering does not affect

distributed search, although the search heads in a cluster can search across the same set of indexers.
