Question #31
When troubleshooting a situation where some files within a directory are not being indexed, the ignored files are discovered to have long headers.
What is the first thing that should be added to inputs.conf?
- A . Decrease the value of initCrcLength.
- B . Add a crcSalt=<string> attribute.
- C . Increase the value of initCrcLength.
- D . Add a crcSalt=<SOURCE> attribute.
Correct Answer: C
C
Explanation:
inputs.conf is a configuration file that contains settings for various types of data inputs, such as files, directories, network ports, scripts, and so on1.
initCrcLength is a setting that specifies the number of characters that the input uses to calculate the CRC (cyclic redundancy check) of a file1. The CRC is a value that uniquely identifies a file based on its content2.
crcSalt is another setting that adds a string to the CRC calculation to force the input to consume files that have matching CRCs1. This can be useful when files have identical headers or when files are renamed or rolled over2.
When troubleshooting a situation where some files within a directory are not being indexed, the ignored files are discovered to have long headers, the first thing that should be added to inputs.conf is to increase the value of initCrcLength. This is because by default, the input only performs CRC checks against the first 256 bytes of a file, which means that files with long headers may have matching CRCs and be skipped by the input2. By increasing the value of initCrcLength, the input can use more characters from the file to calculate the CRC, which can reduce the chances of CRC collisions and ensure that different files are indexed3.
Option C is the correct answer because it reflects the best practice for troubleshooting this situation.
Option A is incorrect because decreasing the value of initCrcLength would make the CRC calculation less reliable and more prone to collisions.
Option B is incorrect because adding a crcSalt with a static string would not help differentiate files with long headers, as they would still have matching CRCs.
Option D is incorrect because adding a crcSalt with the <SOURCE> attribute would add the full directory path to the CRC calculation, which would not help if the files are in the same directory2.

Question #32
To expand the search head cluster by adding a new member, node2, what first step is required?
- A . splunk bootstrap shcluster-config -mgmt_uri https://node2:8089 -replication_port 9200 -secret supersecretkey
- B . splunk init shcluster-config -master_uri https://node2:8089 -replication_port 9200 -secret supersecretkey
- C . splunk init shcluster-config -mgmt_uri https://node2:8089 -replication_port 9200 -secret supersecretkey
- D . splunk add shcluster-member -new_member_uri https://node2:8089 -replication_port 9200 – secret supersecretkey
Correct Answer: C
C
Explanation:
To expand the search head cluster by adding a new member, node2, the first step is to initialize the cluster configuration on node2 using the splunk init shcluster-config command. This command sets the required parameters for the cluster member, such as the management URI, the replication port, and the shared secret key. The management URI must be unique for each cluster member and must match the URI that the deployer uses to communicate with the member. The replication port must be the same for all cluster members and must be different from the management port. The secret key must be the same for all cluster members and must be encrypted using the splunk_encrypt command. The master_uri parameter is optional and specifies the URI of the cluster captain. If not specified, the cluster member will use the captain election process to determine the captain.
Option C shows the correct syntax and parameters for the splunk init shcluster-config command.
Option A is incorrect because the splunk bootstrap shcluster-config command is used to bring up the first cluster member as the initial captain, not to add a new member.
Option B is incorrect because the master_uri parameter is not required and the mgmt_uri parameter is missing.
Option D is incorrect because the splunk add shcluster-member command is used to add an existing search head to the cluster, not to initialize a new member12 1:

Question #36
In search head clustering, which of the following methods can you use to transfer captaincy to a different member? (Select all that apply.)
- A . Use the Monitoring Console.
- B . Use the Search Head Clustering settings menu from Splunk Web on any member.
- C . Run the splunk transfer shcluster-captain command from the current captain.
- D . Run the splunk transfer shcluster-captain command from the member you would like to become the captain.
Correct Answer: B, D
B, D
Explanation:
In search head clustering, there are two methods to transfer captaincy to a different member. One method is to use the Search Head Clustering settings menu from Splunk Web on any member. This method allows the user to select a specific member to become the new captain, or to let Splunk choose the best candidate. The other method is to run the splunk transfer shcluster-captain command from the member that the user wants to become the new captain. This method requires the user to know the name of the target member and to have access to the CLI of that member. Using the Monitoring Console is not a method to transfer captaincy, because the Monitoring Console does not have the option to change the captain. Running the splunk transfer shcluster-captain command from the current captain is not a method to transfer captaincy, because this command will fail with an error message

Question #37
Initialize cluster rebalance operation.
Correct Answer: A
Explanation:
When adding or decommissioning a member from a Search Head Cluster (SHC), the proper order of operations is:
Delete Splunk Enterprise, if it exists.
Install and initialize the instance.
Join the SHC.
This order of operations ensures that the member has a clean and consistent Splunk installation before joining the SHC. Deleting Splunk Enterprise removes any existing configurations and data from the instance. Installing and initializing the instance sets up the Splunk software and the required roles and settings for the SHC. Joining the SHC adds the instance to the cluster and synchronizes the configurations and apps with the other members. The other order of operations are not correct, because they either skip a step or perform the steps in the wrong order.

Question #39
How many cluster managers are required for a multisite indexer cluster?
- A . Two for the entire cluster.
- B . One for each site.
- C . One for the entire cluster.
- D . Two for each site.
Correct Answer: C
C
Explanation:
A multisite indexer cluster is a type of indexer cluster that spans multiple geographic locations or sites. A multisite indexer cluster requires only one cluster manager, also known as the master node, for the entire cluster. The cluster manager is responsible for coordinating the replication and search activities among the peer nodes across all sites. The cluster manager can reside in any site, but it must be accessible by all peer nodes and search heads in the cluster.
Option C is the correct answer.
Option A is incorrect because having two cluster managers for the entire cluster would introduce redundancy and complexity.
Option B is incorrect because having one cluster manager for each site would create separate clusters, not a multisite cluster.
Option D is incorrect because having two cluster managers for each site would be unnecessary and inefficient12

Question #40
Which of the following is a best practice to maximize indexing performance?
- A . Use automatic source typing.
- B . Use the Splunk default settings.
- C . Not use pre-trained source types.
- D . Minimize configuration generality.
Correct Answer: D
D
Explanation:
A best practice to maximize indexing performance is to minimize configuration generality. Configuration generality refers to the use of generic or default settings for data inputs, such as source type, host, index, and timestamp. Minimizing configuration generality means using specific and accurate settings for each data input, which can reduce the processing overhead and improve the indexing throughput. Using automatic source typing, using the Splunk default settings, and not using pre-trained source types are examples of configuration generality, which can negatively affect the indexing performance
