When preparing to ingest a new data source, which of the following is optional in the data source assessment?
Answer : D
Data retention is optional in the data source assessment because it is not directly related to the ingestion process. Data retention is determined by the index configuration and the storage capacity of the Splunk platform. Data format, data location, and data volume are all essential information for planning how to collect, parse, and index the data source.

Where in the Job Inspector can details be found to help determine where performance is affected?
Answer : D
This is where in the Job Inspector details can be found to help determine where performance is affected, as it shows the time and resources spent by each component of the search, such as commands, subsearches, lookups, and post-processing1.The Execution Costs > Components section can help identify the most expensive or inefficient parts of the search, and suggest ways to optimize or improve the search performance1. The other options are not as useful as the Execution Costs > Components section for finding performance issues.Option A, Search Job Properties > runDuration, shows the total time, in seconds, that the search took to run2. This can indicate the overall performance of the search, but it does not provide any details on the specific components or factors that affected the performance.Option B, Search Job Properties > runtime, shows the time, in seconds, that the search took to run on the search head2. This can indicate the performance of the search head, but it does not account for the time spent on the indexers or the network.Option C, Job Details Dashboard > Total Events Matched, shows the number of events that matched the search criteria3. This can indicate the size and scope of the search, but it does not provide any information on the performance or efficiency of the search. Therefore, option D is the correct answer, and options A, B, and C are incorrect.

Which command should be run to re-sync a stale KV Store member in a search head cluster?
Answer : A
To resync a stale KV Store member in a search head cluster, you need to stop the search head that has the stale KV Store member, run the command splunk clean kvstore --local, and then restart the search head.This triggers the initial synchronization from other KV Store members12.
The command splunk resync kvstore [-source sourceId] is used to resync the entire KV Store cluster from one of the members, not a single member.This command can only be invoked from the node that is operating as search head cluster captain2.
The command splunk clean eventdata -local is used to delete all indexed data from a standalone indexer or a cluster peer node, not to resync the KV Store3.

What is the best method for sizing or scaling a search head cluster?
Answer : D
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.
Where does the Splunk deployer send apps by default?
Answer : D
The Splunk deployer sends apps to the search head cluster members by default to the path etc/shcluster/
Splunk's documentation recommends placing the configuration bundle in the $SPLUNK_HOME/etc/shcluster/apps directory on the deployer, which then gets distributed to the search head cluster members. However, it should be noted that within each app's directory, configurations can be under default or local subdirectories, with local taking precedence over default for configurations. The reference to etc/shcluster/
