Question 1

A customer has downloaded the Splunk App for AWS from Splunkbase and installed it in a search
head cluster following the instructions using the deployer. A power user modifies a dashboard in the
app on one of the search head cluster members. The app containing an updated dashboard is
upgraded to the latest version by following the instructions via the deployer.
What happens?

Accepted Answer

D

Explanation: Splunk's configuration system operates on a file precedence hierarchy. When a power user modifies and saves a dashboard within an app, a copy of that dashboard's configuration is saved in their specific user directory (etc/users/ / /local/). This user-specific configuration has a higher precedence for that user than the app-level configurations located in etc/apps/ /. When the app is upgraded via the deployer, the app-level files are updated, but the user's private, modified copy remains untouched. Consequently, the power user will continue to see their own modified version of the dashboard, not the newly deployed one.

Question 2

When can the Search Job Inspector be used to debug searches?

Accepted Answer

Question 3

A customer wants to understand how Splunk bucket types (hot, warm, cold) impact search
performance within their environment. Their indexers have a single storage device for all dat
a. What is the proper message to communicate to the customer?

Accepted Answer

A

Explanation: The primary factor that differentiates search performance between hot, warm, and cold buckets is the speed of the underlying storage media they reside on. The question explicitly states the customer's indexers use a "single storage device for all data." In this configuration, hot, warm, and cold buckets all reside on the same physical storage. Warm and cold buckets are structurally identical (read-only, with rawdata and index files). While hot buckets are actively being written to, which can introduce minimal I/O contention, the overall search performance characteristics across all three bucket types are effectively the same because the major performance variable—tiered storage—is not present.

Question 4

Which of the following statements applies to indexer discovery?

Accepted Answer

B

Explanation: Indexer discovery is a specific feature in Splunk indexer clustering designed for forwarders. It allows forwarders to automatically learn the set of active peer nodes (indexers) by querying the Cluster Master (CM). The forwarder is configured with the CM's address, and it periodically fetches the list of indexers to which it can send data. This mechanism enables forwarders to load balance data across all available indexers and adapt dynamically as indexers are added to or removed from the cluster, without needing manual reconfiguration on the forwarder itself.

Question 5

A site from a multi-site indexer cluster needs to be decommissioned. Which of the following actions must be taken?

Accepted Answer

D

Explanation: Decommissioning a site in a Splunk multi-site indexer cluster is a two-fold process. First, the cluster manager must be informed that the site is no longer available. This is accomplished by removing the site's configuration stanza from the server.conf file on the manager node. Second, the data ingestion path must be updated. Forwarders that were configured to send data to the peers in the decommissioned site must be reconfigured to send data to peers in the remaining active sites. This ensures both cluster stability and the continuity of data flow. Option D correctly identifies both of these essential actions.

Question 6

A customer has asked for a five-node search head cluster (SHC), but does not have the storage
budget to use a replication factor greater than 2. They would like to understand what might happen
in terms of the users’ ability to view historic scheduled search results if they log onto a search head
which doesn’t contain one of the 2 copies of a given search artifact.
Which of the following statements best describes what would happen in this scenario?

Accepted Answer

A

Explanation: In a Splunk Search Head Cluster (SHC), if a user requests a search artifact (like historical scheduled search results) that is not stored locally on the search head they are connected to, the system is designed for high availability. The search head will contact a peer node that holds a copy of the artifact and proxy the necessary data to fulfill the user's request. Subsequently, to optimize future access and maintain data locality, the cluster's replication mechanism will create a permanent copy of that artifact on the requesting search head. This ensures both immediate access and improved performance for subsequent requests.

Question 7

When adding a new search head to a search head cluster (SHC), which of the following scenarios occurs?

Accepted Answer

A

Explanation: When a new member boots, it joins the search-head cluster by contacting the current captain. The captain then replicates the latest peer-generated and captain-generated configurations (knowledge objects, search artifacts, and any cluster-replicated configuration bundle) so the new node is immediately consistent with the rest of the cluster. Search-head cluster members never initiate contact with the deployer; the deployer only delivers app/configuration bundles when an administrator runs splunk apply shcluster-bundle. Therefore, only the captain is involved automatically when a new search head is added.

Question 8

In which of the following scenarios should base configurations be used to provide consistent, repeatable, and supportable configurations?

Accepted Answer

D

Explanation: Base configurations are designed to establish a standardized, supportable foundation for a Splunk environment. This foundation contains common settings that apply broadly. The primary purpose of this approach is to create a consistent starting point that can then be efficiently customized with specific settings to meet unique customer or environmental requirements. This layered approach, where specific configurations override or augment the base, ensures both repeatability and the flexibility needed for diverse use cases.

Question 9

A customer has the following Splunk instances within their environment: An indexer cluster
consisting of a cluster master/master node and five clustered indexers, two search heads (no search
head clustering), a deployment server, and a license master. The deployment server and license
master are running on their own single-purpose instances. The customer would like to start using the
Monitoring Console (MC) to monitor the whole environment.
On the MC instance, which instances will need to be configured as distributed search peers by
specifying them via the UI using the settings menu?

Accepted Answer

C

Explanation: The Monitoring Console (MC) functions as a dedicated search head to monitor the health and performance of a Splunk environment. To gather data, it must be configured to search all other Splunk instances. In a distributed deployment, this is achieved by adding the instances as search peers. For an indexer cluster, only the cluster master node is added as a search peer to the MC. The cluster master then manages and forwards search requests to the indexer peers. All other single-purpose instances, including standalone search heads, the deployment server, and the license master, must be added individually as search peers to the MC.

Question 10

A [script://] input sends data to a Splunk forwarder using which method?

Accepted Answer

D

Explanation: The script:// input type in Splunk is designed to execute a specified script or command at a defined interval. The Splunk software then captures any data that the script writes to its standard output (STDOUT) or standard error (STDERR) streams. This captured output is treated as event data, which is then parsed and forwarded through the Splunk data pipeline for indexing. This mechanism allows Splunk to ingest data from sources that are not file-based, such as APIs or command-line tools, by wrapping them in a script.

Question 11

A customer wants to migrate from using Splunk local accounts to use Active Directory with LDAP for
their Splunk user accounts instead. Which configuration files must be modified to connect to an
Active Directory LDAP provider?

Accepted Answer

C

Explanation: Splunk stores all information required to reach and bind to an external LDAP directory—server URI, bind DN, SSL settings, search bases, group-mapping, etc.—in authentication.conf. No other .conf file is required for establishing or maintaining the LDAP connection; authorize.conf is only needed when you define custom roles or capabilities and ldap.conf does not exist in Splunk. Therefore, to “connect to an Active Directory LDAP provider” you must modify authentication.conf only.

Question 12

As a best practice which of the following should be used to ingest data on clustered indexers?

Accepted Answer

D

Explanation: In a distributed Splunk architecture, the best practice is to separate the data collection and data indexing tiers. Clustered indexers are optimized for receiving, parsing, indexing, and servicing search requests. Their primary ingestion role is to listen for data sent from other sources. The standard and most scalable methods for this are receiving forwarded data via splunktcp or splunktcp-ssl from Universal or Heavy Forwarders, and receiving data from applications and services via the HTTP Event Collector (HEC). Placing file monitoring or other direct collection inputs on indexers is an anti-pattern that can create single points of failure and adds unnecessary processing load, undermining the resilience and performance of the cluster.

Question 13

How does Monitoring Console (MC) initially identify the server role(s) of a new Splunk Instance?

Accepted Answer

A

Explanation: The Monitoring Console (MC) performs an initial, automatic discovery of a Splunk instance's roles by querying that instance's REST API. Specifically, it uses the /services/server/info endpoint. This endpoint returns comprehensive information about the server, including a serverroles attribute that explicitly lists all roles the instance is configured to perform (e.g., indexer, searchhead, clustermanager, licensemanager). This API-driven method is the direct and authoritative mechanism the MC uses to identify which health checks and dashboards are applicable to the new instance.

Question 14

Which configuration item should be set to false to significantly improve data ingestion performance?

Accepted Answer

C

Explanation: The SHOULDLINEMERGE setting in props.conf dictates whether Splunk should attempt to combine multiple lines of incoming data into a single event. This process, known as event aggregation, is one of the most resource-intensive parts of the data ingestion pipeline. When SHOULDLINEMERGE is true, Splunk must buffer data and apply pattern matching to identify event boundaries, which consumes significant CPU and memory. By setting SHOULDLINEMERGE = false for data sources that are known to be single-line events, this entire aggregation process is skipped. Each line is treated as a separate event, which dramatically reduces processing load and significantly improves ingestion performance.

Question 15

How could a role in which all users must specify an index=clause in all searches be configured?

Accepted Answer

A

Explanation: The srchIndexesDefault parameter in a role's stanza within authorize.conf specifies the default index or indexes to be searched if the user's search query does not contain an index= clause. By setting this parameter to no value (i.e., srchIndexesDefault =), you remove any default search path. Consequently, a search without an explicit index= clause will run against zero indexes, returning no results. This effectively compels users in that role to specify the target index in every search to retrieve data.
