Which of the following is unsupported in a production environment?
A. Search Head Cluster Deployer can run on the Monitoring Console instance in smaller environments.
B. Cluster Manager can run on the Monitoring Console instance in smaller environments.
C. Indexers in an indexer cluster can run on virtual machines.
D. Search heads in a Search Head Cluster can run on virtual machines.
正解：B、C
解説：
Comprehensive and Detailed Explanation (From Splunk Enterprise Documentation)Splunk Enterprise documentation clarifies that none of the listed configurations are prohibited in production. Splunk allows the Cluster Manager to be colocated with the Monitoring Console in small deployments because both are management-plane functions and do not handle ingestion or search traffic. The documentation also states that the Search Head Cluster Deployer is not a runtime component and has minimal performance requirements, so it may be colocated with the Monitoring Console or Licensing Master when hardware resources permit.
Splunk also supports virtual machines for both search heads and indexers, provided they are deployed with dedicated CPU, storage throughput, and predictable performance. Splunk's official hardware guidance specifies that while bare metal often yields higher performance, virtualized deployments are fully supported in production as long as sizing principles are met.
Because Splunk explicitly supports all four configurations under proper sizing and best-practice guidelines, there is no correct selection for "unsupported." The question is outdated relative to current Splunk Enterprise recommendations.

What does setting site=site0 on all Search Head Cluster members do in a multi-site indexer cluster?
A. Disables search site affinity.
B. Enables multisite search artifact replication.
C. Enables automatic search site affinity discovery.
D. Sets all members to dynamic captaincy.
正解：A
解説：
Setting site=site0 on all Search Head Cluster members disables search site affinity. Search site affinity is a feature that allows search heads to preferentially search the peer nodes that are in the same site as the search head, to reduce network latency and bandwidth consumption. By setting site=site0, which is a special value that indicates no site, the search heads will search all peer nodes regardless of their site. Setting site=site0 does not set all members to dynamic captaincy, enable multisite search artifact replication, or enable automatic search site affinity discovery. Dynamic captaincy is a feature that allows any member to become the captain, and it is enabled by default. Multisite search artifact replication is a feature that allows search artifacts to be replicated across sites, and it is enabled by setting site_replication_factor to a value greater than
1. Automatic search site affinity discovery is a feature that allows search heads to automatically determine their site based on the network latency to the peer nodes, and it is enabled by setting site=auto

A new Splunk customer is using syslog to collect data from their network devices on port 514. What is the best practice for ingesting this data into Splunk?
A. Configure syslog to send the data to multiple Splunk indexers.
B. Configure syslog to write logs and use a Splunk forwarder to collect the logs.
C. Use a Splunk indexer to collect a network input on port 514 directly.
D. Use a Splunk forwarder to collect the input on port 514 and forward the data.
正解：B
解説：
The best practice for ingesting syslog data from network devices on port 514 into Splunk is to configure syslog to write logs and use a Splunk forwarder to collect the logs. This practice will ensure that the data is reliably collected and forwarded to Splunk, without losing any data or overloading the Splunk indexer.
Configuring syslog to send the data to multiple Splunk indexers will not guarantee data reliability, as syslog is a UDP protocol that does not provide acknowledgment or delivery confirmation. Using a Splunk indexer to collect a network input on port 514 directly will not provide data reliability or load balancing, as the indexer may not be able to handle the incoming data volume or distribute it to other indexers. Using a Splunk forwarder to collect the input on port 514 and forward the data will not provide data reliability, as the forwarder may not be able to receive the data from syslog or buffer it in case of network issues. For more information, see [Get data from TCP and UDP ports] and [Best practices for syslog data] in the Splunk documentation.
質問 # 24
When converting from a single-site to a multi-site cluster, what happens to existing single-site clustered
buckets?
A. They will continue to replicate within the origin site and age out based on existing policies.
B. They will be replicated across all peers in the multi-site cluster and age out based on existing policies.
C. They will stop replicating within the single-site and remain on the indexer they reside on and age out
according to existing policies.
D. They will maintain replication as required according to the single-site policies, but never age out.
