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: D

Correct Answer: A

Correct Answer: D

When using a directory monitor input, specific source types can be selectively overridden using the props.conf file. According to the Splunk documentation, "You can specify a source type for data based on its input and source. Specify source type for an input. You can assign the source type for data coming from a specific input, such as /var/log/. If you use Splunk Cloud Platform, use Splunk Web to define source types. If you use Splunk Enterprise, define source types in Splunk Web or by editing the inputs.conf configuration file." However, this method is not very granular and assigns the same source type to all data from an input. To override the source type on a per-event basis, you need to use the props.conf file and the transforms.conf file. The props.conf file contains settings that determine how the Splunk platform processes incoming data, such as how to segment events, extract fields, and assign source types. The transforms.conf file contains settings that modify or filter event dataduring indexing or search time. You can use these files to create rules that match specific patterns in the event data and assign different source types accordingly. For example, you can create a rule that assigns a source type of apache_error to any event that contains the word "error" in the first line.

Correct Answer: C

https://docs.splunk.com/Documentation/Splunk/8.1.1/DistSearch/Forwardsearchheaddata Per the provided Splunk reference URL by @hwangho, scroll to section Forward search head data, subsection titled, 2. Configure the search head as a forwarder. "Create an outputs.conf file on the search head that configures the search head for load-balanced forwarding across the set of search peers (indexers)."

Correct Answer: A

This option corresponds to the file path "$SPLUNK_HOME/etc/apps/splunk_TA_nginx/local/inputs.conf". This is the configuration file that the user needs to edit to ingest the NGINX access logs to ensure it remains unaffected after upgrade.

This is explained in the Splunk documentation, which states:

The local directory is where you place your customized configuration files. The local directory is empty when you install Splunk Enterprise. You create it when you need to override or add to the default settings in a configuration file. The local

directory is never overwritten during an upgrade.

Correct Answer: A

https://docs.splunk.com/Documentation/Splunk/8.2.2/Data/AboutHECIDXAck

-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: D

"The search head replicates the knowledge bundle periodically in the background or when initiating a search. " "As part of the distributed search process, the search head replicates and distributes its knowledge objects to its search peers, or indexers. Knowledge objects include saved searches, event types, and other entities used in searching accorss indexes. The search head needs to distribute this material to its search peers so that they can properly execute queries on its behalf."

Correct Answer: B

Reference:https://docs.splunk.com/Documentation/Splunk/8.2.3/Data/FormateventsforHTT PEventCollector

When creating an HTTP event, the request header must include a token that identifies the HTTP Event Collector (HEC) endpoint. The token is a 32-character hexadecimal string that is generated when the HEC endpoint is created. The token is used to authenticate the request and route the event data to the correct index. Therefore, option B is the correct answer. References: Splunk Enterprise Certified Admin | Splunk, [About HTTP Event Collector - Splunk Documentation]
