質問 # 26
In a four site indexer cluster, which configuration stores two searchable copies at the origin site, one searchable copy at site2, and a total of four searchable copies?
- A. site_replication_factor = origin:2, site2:1, total:4
- B. site_search_factor = origin:2, site2:1, total:4
- C. site_replication_factor = origin:2, site1:2, total:4
- D. site_search_factor = origin:2, site1:2, total:4
正解：B
解説：
Explanation
In a four site indexer cluster, the configuration that stores two searchable copies at the origin site, one searchable copy at site2, and a total of four searchable copies is site_search_factor = origin:2, site2:1, total:4.
This configuration tells the cluster to maintain two copies of searchable data at the site where the data originates, one copy of searchable data at site2, and a total of four copies of searchable data across all sites.
The site_search_factor determines how many copies of searchable data are maintained by the cluster for each site. The site_replication_factor determines how many copies of raw data are maintained by the cluster for each site. For more information, see Configure multisite indexer clusters with server.conf in the Splunk documentation.
質問 # 27
A customer currently has many deployment clients being managed by a single, dedicated deployment server.
The customer plans to double the number of clients.
What could be done to minimize performance issues?
- A. Modify deploymentclient. conf to change from a Pull to Push mechanism.
- B. Decrease the current deployment client phone home interval.
- C. Reduce the number of apps in the Manager Node repository.
- D. Increase the current deployment client phone home interval.
正解：D
解説：
According to the Splunk documentation1, increasing the current deployment client phone home interval can minimize performance issues by reducing the frequency of communication between the clients and the deployment server. This can also reduce the network traffic and the load on the deployment server. The other options are false because:
* Modifying deploymentclient.conf to change from a Pull to Push mechanism is not possible, as Splunk
* does not support a Push mechanism for deployment server2.
* Reducing the number of apps in the Manager Node repository will not affect the performance of the deployment server, as the apps are only downloaded when there is a change in the configuration or a new app is added3.
* Decreasing the current deployment client phone home interval will increase the performance issues, as it will increase the frequency of communication between the clients and the deployment server, resulting in more network traffic and load on the deployment server1.
質問 # 28
A Splunk instance has the following settings in SPLUNK_HOME/etc/system/local/server.conf:
[clustering]
mode = master
replication_factor = 2
pass4SymmKey = password123
Which of the following statements describe this Splunk instance? (Select all that apply.)
- A. This instance is missing the master_uri attribute.
- B. This cluster's search factor is 2.
- C. This Splunk instance needs to be restarted.
- D. This is a multi-site cluster.
正解：A、C
解説：
Explanation
The Splunk instance with the given settings in SPLUNK_HOME/etc/system/local/server.conf is missing the master_uri attribute and needs to be restarted. The master_uri attribute is required for the master node to communicate with the peer nodes and the search head cluster. The master_uri attribute specifies the host name and port number of the master node. Without this attribute, the master node cannot function properly. The Splunk instance also needs to be restarted for the changes in the server.conf file to take effect. The replication_factor setting determines how many copies of each bucket are maintained across the peer nodes.
The search factor is a separate setting that determines how many searchable copies of each bucket are maintained across the peer nodes. The search factor is not specified in the given settings, so it defaults to the same value as the replication factor, which is 2. This is not a multi-site cluster, because the site attribute is not specified in the clustering stanza. A multi-site cluster is a cluster that spans multiple geographic locations, or sites, and has different replication and search factors for each site.
質問 # 29
Consider a use case involving firewall data. There is no Splunk-supported Technical Add-On, but the vendor has built one. What are the items that must be evaluated before installing the add-on? (Select all that apply.)
- A. Validate if this Technical Add-On enables event data for a data model.
- B. Identify number of scheduled or real-time searches.
- C. Identify the maximum number of forwarders Technical Add-On can support.
- D. Verify if Technical Add-On needs to be installed onto both a search head or indexer.
正解：A、B
解説：
Explanation
A Technical Add-On (TA) is a Splunk app that contains configurations for data collection, parsing, and enrichment. It can also enable event data for a data model, which is useful for creating dashboards and reports.
Therefore, before installing a TA, it is important to identify the number of scheduled or real-time searches that will use the data model, and to validate if the TA enables event data for a data model. The number of forwarders that the TA can support is not relevant, as the TA is installed on the indexer or search head, not on the forwarder. The installation location of the TA depends on the type of data and the use case, so it is not a fixed requirement
質問 # 30
How does the average run time of all searches relate to the available CPU cores on the indexers?
- A. Average run time is independent of the number of CPU cores on the indexers.
- B. Average run time increases as the number of CPU cores on the indexers decreases.
- C. Average run time decreases as the number of CPU cores on the indexers decreases.
- D. Average run time increases as the number of CPU cores on the indexers increases.
正解：B
解説：
The average run time of all searches increases as the number of CPU cores on the indexers decreases. The CPU cores are the processing units that execute the instructions and calculations for the data. The number of CPU cores on the indexers affects the search performance, because the indexers are responsible for retrieving and filtering the data from the indexes. The more CPU cores the indexers have, the faster they can process the data and return the results. The less CPU cores the indexers have, the slower they can process the data and return the results. Therefore, the average run time of all searches is inversely proportional to the number of CPU cores on the indexers. The average run time of all searches is not independent of the number of CPU cores on the indexers, because the CPU cores are an important factor for the search performance. The average run time of all searches does not decrease as the number of CPU cores on the indexers decreases, because this would imply that the search performance improves with less CPU cores, which is not true. The average run time of all searches does not increase as the number of CPU cores on the indexers increases, because this would imply that the search performance worsens with more CPU cores, which is not true
質問 # 31
When Splunk is installed. where are the internal indexes stored by default?
- A. SPLUNK_HOME/var/lib
- B. SPLUNK_HOME/bin
- C. SPLUNK_HOME/etc/system/default
- D. SPLUNK_HOME/var/run
正解：A
質問 # 32
To activate replication for an index in an indexer cluster, what attribute must be configured in indexes.conf on all peer nodes?
- A. repFactor = auto
- B. replicate = 0
- C. replicate = auto
- D. repFactor = 0
正解：A
解説：
Explanation
To activate replication for an index in an indexer cluster, the repFactor attribute must be configured in indexes.conf on all peer nodes. This attribute specifies the replication factor for the index, which determines how many copies of raw data are maintained by the cluster. Setting the repFactor attribute to auto will enable replication for the index. The replicate attribute in indexes.conf is not a valid Splunk attribute. The repFactor attribute in outputs.conf and the replicate attribute in deploymentclient.conf are not related to replication for an index in an indexer cluster. For more information, see Configure indexes for indexer clusters in the Splunk documentation.

質問 # 34
Which of the following is a good practice for a search head cluster deployer?
- A. The deployer only distributes configurations to search head cluster members with splunk apply shcluster-bundle.
- B. The deployer only distributes configurations to search head cluster members when they "phone home".
- C. The deployer must be used to distribute non-replicable configurations to search head cluster members.
- D. The deployer must distribute configurations to search head cluster members to be valid configurations.
正解：C
解説：
Explanation
The following is a good practice for a search head cluster deployer: The deployer must be used to distribute non-replicable configurations to search head cluster members. Non-replicable configurations are the configurations that are not replicated by the search factor, such as the apps and the server.conf settings. The deployer is the Splunk server role that distributes these configurations to the search head cluster members, ensuring that they have the same configuration. The deployer does not only distribute configurations to search head cluster members when they "phone home", as this would cause configuration inconsistencies and delays.
The deployer does not distribute configurations to search head cluster members to be valid configurations, as this implies that the configurations are invalid without the deployer. The deployer does not only distribute configurations to search head cluster members with splunk apply shcluster-bundle, as this would require manual intervention by the administrator. For more information, see Use the deployer to distribute apps and configuration updates in the Splunk documentation.

質問 # 36
Which of the following should be done when installing Enterprise Security on a Search Head Cluster? (Select all that apply.)
- A. Install Enterprise Security on the deployer.
- B. Copy the Enterprise Security configurations to the deployer.
- C. Use the deployer to deploy Enterprise Security to the cluster members.
- D. Install Enterprise Security on a staging instance.
正解：A、C
解説：
When installing Enterprise Security on a Search Head Cluster (SHC), the following steps should be done:
Install Enterprise Security on the deployer, and use the deployer to deploy Enterprise Security to the cluster members. Enterprise Security is a premium app that provides security analytics and monitoring capabilities for Splunk. Enterprise Security can be installed on a SHC by using the deployer, which is a standalone instance that distributes apps and other configurations to the SHC members. Enterprise Security should be installed on the deployer first, and then deployed to the cluster members using the splunk apply shcluster-bundle command. Enterprise Security should not be installed on a staging instance, because a staging instance is not part of the SHC deployment process. Enterprise Security configurations should not be copied to the deployer, because they are already included in the Enterprise Security app package.
質問 # 37
When Splunk indexes data in a non clustered environment, what kind of files does it create by default?
- A. Rawdata and index files.
- B. Compressed and meta data files.
- C. Compressed and .tsidx files.
- D. Index and .tsidx files.
正解：A

質問 # 38
What log file would you search to verify if you suspect there is a problem interpreting a regular expression in a monitor stanza?
- A. tailing_processor.log
- B. metrics.log
- C. splunkd.log
- D. btool.log
正解：A
解説：
The tailing_processor.log file would be the best place to search if you suspect there is a problem interpreting a regular expression in a monitor stanza. This log file contains information about how Splunk monitors files and directories, including any errors or warnings related to parsing the monitor stanza. The splunkd.log file contains general information about the Splunk daemon, but it may not have the specific details about the monitor stanza. The btool.log file contains information about the configuration files, but it does not log the runtime behavior of the monitor stanza. The metrics.log file contains information about the performance metrics of Splunk, but it does not log the event breaking issues. For more information, see About Splunk Enterprise logging in the Splunk documentation.

質問 # 44
What is the best method for sizing or scaling a search head cluster?
- A. Estimate the maximum daily ingest volume in gigabytes and divide by the number of CPU cores per search head.
- B. Divide the number of indexers by three to achieve the correct number of search heads.
- C. Estimate the maximum concurrent number of searches and divide by the number of CPU cores per search head.
- D. Estimate the total number of searches per day and divide by the number of CPU cores available on the search heads.
正解：C
解説：
According to the Splunk blog1, the best method for sizing or scaling a search head cluster is to estimate the maximum concurrent number of searches and divide by the number of CPU cores per search head. This gives you an idea of how many search heads you need to handle the peak search load without overloading the CPU resources. The other options are false because:
* Estimating the maximum daily ingest volume in gigabytes and dividing by the number of CPU cores per search head is not a good method for sizing or scaling a search head cluster, as it does not account for the complexity and frequency of the searches. The ingest volume is more relevant for sizing or scaling the indexers, not the search heads2.
* Estimating the total number of searches per day and dividing by the number of CPU cores available on the search heads is not a good method for sizing or scaling a search head cluster, as it does not account for the concurrency and duration of the searches. The total number of searches per day is an average metric that does not reflect the peak search load or the search performance2.
* Dividing the number of indexers by three to achieve the correct number of search heads is not a good method for sizing or scaling a search head cluster, as it does not account for the search load or the search head capacity. The number of indexers is not directly proportional to the number of search heads, as different types of data and searches may require different amounts of resources2.
質問 # 45
Which of the following statements describe search head clustering? (Select all that apply.)
- A. A deployer is required.
- B. The deployer must have sufficient CPU and network resources to process service requests and push configurations.
- C. At least three search heads are needed.
- D. Search heads must meet the high-performance reference server requirements.
正解：A、B、C
解説：
Search head clustering is a Splunk feature that allows a group of search heads to share configurations, apps, and knowledge objects, and to provide high availability and scalability for searching. Search head clustering has the following characteristics:
* A deployer is required. A deployer is a Splunk instance that distributes the configurations and apps to the members of the search head cluster. The deployer is not a member of the cluster, but a separate instance that communicates with the cluster master.
* At least three search heads are needed. A search head cluster must have at least three search heads to form a quorum and to ensure high availability. If the cluster has less than three search heads, it cannot function properly and will enter a degraded mode.
* The deployer must have sufficient CPU and network resources to process service requests and push
* configurations. The deployer is responsible for handling the requests from the cluster master and the cluster members, and for pushing the configurations and apps to the cluster members. Therefore, the deployer must have enough CPU and network resources to perform these tasks efficiently and reliably.
Search heads do not need to meet the high-performance reference server requirements, as this is not a mandatory condition for search head clustering. The high-performance reference server requirements are only recommended for optimal performance and scalability of Splunk deployments, but they are not enforced by Splunk.
質問 # 46
A three-node search head cluster is skipping a large number of searches across time. What should be done to increase scheduled search capacity on the search head cluster?
- A. server.conf captain_is_adhoc_searchhead = true.
- B. Create a job server on the cluster.
- C. Add another search head to the cluster.
- D. Change limits.conf value for max_searches_per_cpu to a higher value.
正解：D
解説：
Explanation
Changing the limits.conf value for max_searches_per_cpu to a higher value is the best option to increase scheduled search capacity on the search head cluster when a large number of searches are skipped across time.
This value determines how many concurrent scheduled searches can run on each CPU core of the search head.
Increasing this value will allow more scheduled searches to run at the same time, which will reduce the number of skipped searches. Creating a job server on the cluster, running the server.conf captain_is_adhoc_searchhead = true command, or adding another search head to the cluster are not the best options to increase scheduled search capacity on the search head cluster. For more information, see [Configure limits.conf] in the Splunk documentation.
質問 # 47
Which of the following statements describe licensing in a clustered Splunk deployment? (Select all that apply.)
- A. Each cluster member requires its own clustering license.
- B. Free licenses do not support clustering.
- C. Replicated data does not count against licensing.
- D. Cluster members must share the same license pool and license master.
正解：B、C
解説：
The following statements describe licensing in a clustered Splunk deployment: Free licenses do not support clustering, and replicated data does not count against licensing. Free licenses are limited to 500 MB of daily indexing volume and do not allow distributed searching or clustering. To enable clustering, a license with a higher volume limit and distributed features is required. Replicated data is data that is copied from one peer node to another for the purpose of high availability and load balancing. Replicated data does not count against licensing, because it is not new data that is ingested by Splunk. Only the original data that is indexed by the peer nodes counts against licensing. Each cluster member does not require its own clustering license, because clustering licenses are shared among the cluster members. Cluster members must share the same license pool and license master, because the license master is responsible for distributing licenses to the cluster members and enforcing the license limits
