SPLK-1003 Online Practice Questions and Answers

Correct Answer: C

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.

Correct Answer: C

The correct answer is C. MonitorNoHandle. MonitorNoHandle is a type of input stanza that allows a Splunk forwarder to read files on Windows systems as Windows writes to them.It does this by using a kernel-mode filter driver to capture raw

data as it gets written to the file1.This input stanza is useful for files that get locked open for writing, such as the Windows DNS server log file2.

The other options are incorrect because:

A. Tail Reader is not a valid input stanza in Splunk.It is a component of the Tailing Processor, which is responsible for monitoring files and directories for new data3. B. Upload is a type of input stanza that allows Splunk to index a single file from a local or network file system.It is not suitable for files that are constantly being updated, as it only indexes the file once and does not monitor it for changes4. D. Monitor is a type of input stanza that allows Splunk to monitor files and directories for new data. However, it may not work for files that Windows prevents Splunk from reading while they are open.In such cases, MonitorNoHandle is a better option2.

A Splunk forwarder is a lightweight agent that can forward data to a Splunk deployment. There are two types of forwarders: universal and heavy.A universal forwarder can only forward data, while a heavy forwarder can also perform parsing,

filtering, routing, and aggregation on the data before forwarding it5. An input stanza is a section in the inputs.conf configuration file that defines the settings for a specific type of input, such as files, directories, network ports, scripts, or

Windows event logs. An input stanza starts with a square bracket, followed by the input type and the input path or name. For example, [monitor:///var/log] is an input stanza for monitoring the /var/log directory.

Correct Answer: A

A Heavy Forwarder is a Splunk instance that can parse and filter data before forwarding it to another Splunk instance, such as an indexer1. A Heavy Forwarder can also perform index-time field extractions using the TRANSFORMS setting2.

The TRANSFORMS setting is used to configure data transformations in the transforms.conf file3. The transforms.conf file contains settings and values that you canuse to configure host and source type overrides, anonymize sensitive data,

route events to different indexes, create index-time and search-time field extractions, and set up lookup tables3.

The TRANSFORMS setting can be deployed to the Heavy Forwarder where the syslog files are being monitored, so that the logs can be rerouted based on the event message before they are forwarded to the indexer2. This can improve the

performance and efficiency of data processing and indexing2.

Behind the scenes, the search head distributes the query to its search peers, and consolidates the results when presenting them to the user."

-Section: About channels and sending data

Sending events to HEC with indexer acknowledgment active is similar to sending them with the setting off. There is one crucial difference: when you have indexer acknowledgment turned on, you must specify a channel when you send

events. The concept of a channel was introduced in HEC primarily to prevent a fast client from impeding the performance of a slow client. When you assign one channel per client, because channels are treated equally on Splunk Enterprise,

one client can't affect another. You must include a matching channel identifier both when sending data to HEC in an HTTP request and when requesting acknowledgment that events contained in the request have been indexed. If you don't,

you will receive the error message, "Data channel is missing." Each request that includes a token for which indexer acknowledgment has been enabled must include a channel identifier, as shown in the following example cURL statement,

where represents the event data portion of the request

Correct Answer: AC

Reference:https://community.splunk.com/t5/Getting-Data-In/Why-does-Splunk-have- multiple-indexes/m-p/12063

Different retention times: You can set different retention policies for different indexes, depending on how long you want to keep the data. For example, you can have an index for security data that has a longer retention time than an index for performance data that has a shorter retention time.

Restrict user permissions: You can set different access permissions for different indexes, depending on who needs to see the data. For example, you can have an index for sensitive data that is only accessible by certain users or roles, and an index for public data that is accessible by everyone.

Correct Answer: C

According to the Splunk documentation1, event processing occurs at the parsing phase of the data pipeline. The parsing phase is where Splunk software processes incoming data into individual events, extracts timestamp information, assigns source types, and performs other tasks to make the data searchable1. The parsing phase can also apply field extractions, event type matching, and other transformations to the events2.

The settings are independent. If you do define both filters and a file matches them both, Splunk Enterprise does not index that file, as the blacklist filter overrides the whitelist filter."
