Users are asking the Splunk administrator to thaw recently-frozen buckets very frequently. What could the Splunk administrator do to reduce the need to thaw buckets?
A. Change f rozenTimePeriodlnSecs to a larger value.
B. Change maxTotalDataSizeMB to a smaller value.
C. Change maxHotSpanSecs to a larger value.
D. Change coldToFrozenDir to a different location.
Explanation: The correct answer is A. Change frozenTimePeriodInSecs to a larger value. This is a possible solution to reduce the need to thaw buckets, as it increases the time period before a bucket is frozen and removed from the index1. The frozenTimePeriodInSecs attribute specifies the maximum age, in seconds, of the data that the index can contain1. By setting it to a larger value, the Splunk administrator can keep the data in the index for a longer time, and avoid having to thaw the buckets frequently. The other options are not effective solutions to reduce the need to thaw buckets. Option B, changing maxTotalDataSizeMB to a smaller value, would actually increase the need to thaw buckets, as it decreases the maximum size, in megabytes, of an index2. This means that the index would reach its size limit faster, and more buckets would be frozen and removed. Option C, changing maxHotSpanSecs to a larger value, would not affect the need to thaw buckets, as it only changes the maximum lifetime, in seconds, of a hot bucket3. This means that the hot bucket would stay hot for a longer time, but it would not prevent the bucket from being frozen eventually. Option D, changing coldToFrozenDir to a different location, would not reduce the need to thaw buckets, as it only changes the destination directory for the frozen buckets4. This means that the buckets would still be frozen and removed from the index, but they would be stored in a different location. Therefore, option A is the correct answer, and options B, C, and D are incorrect.
When preparing to ingest a new data source, which of the following is optional in the data source assessment?
A. Data format
B. Data location
C. Data volume
D. Data retention
Explanation: 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.
When should a Universal Forwarder be used instead of a Heavy Forwarder?
A. When most of the data requires masking.
B. When there is a high-velocity data source.
C. When data comes directly from a database server.
D. When a modular input is needed.
Explanation:
According to the Splunk blog1, the Universal Forwarder is ideal for collecting data from
high-velocity data sources, such as a syslog server, due to its smaller footprint and faster
performance. The Universal Forwarder performs minimal processing and sends raw or
unparsed data to the indexers, reducing the network traffic and the load on the forwarders.
The other options are false because:
A monitored log file is changing on the forwarder. However, Splunk searches are not finding any new data that has been added. What are possible causes? (select all that apply)
A. An admin ran splunk clean eventdata -index
B. An admin has removed the Splunk fishbucket on the forwarder.
C. The last 256 bytes of the monitored file are not changing.
D. The first 256 bytes of the monitored file are not changing.
Explanation:
A monitored log file is changing on the forwarder, but Splunk searches are not finding any
new data that has been added. This could be caused by two possible reasons: B. An admin
has removed the Splunk fishbucket on the forwarder. C. The last 256 bytes of the
monitored file are not changing. Option B is correct because the Splunk fishbucket is a
directory that stores information about the files that have been monitored by Splunk, such
as the file name, size, modification time, and CRC checksum. If an admin removes the
fishbucket, Splunk will lose track of the files that have been previously indexed and will not
index any new data from those files. Option C is correct because Splunk uses the CRC
checksum of the last 256 bytes of a monitored file to determine if the file has changed since
the last time it was read. If the last 256 bytes of the file are not changing, Splunk will
assume that the file is unchanged and will not index any new data from it. Option A is
incorrect because running the splunk clean eventdata -index
Which of the following items are important sizing parameters when architecting a Splunk environment? (select all that apply)
A. Number of concurrent users.
B. Volume of incoming data.
C. Existence of premium apps.
D. Number of indexes.
Explanation:
Number of concurrent users: This is an important factor because it affects the
search performance and resource utilization of the Splunk environment. More
users mean more concurrent searches, which require more CPU, memory, and
disk I/O. The number of concurrent users also determines the search head
capacity and the search head clustering configuration12.
Volume of incoming data: This is another crucial factor because it affects the
indexing performance and storage requirements of the Splunk environment. More
data means more indexing throughput, which requires more CPU, memory, and
disk I/O. The volume of incoming data also determines the indexer capacity and
the indexer clustering configuration13.
Existence of premium apps: This is a relevant factor because some premium apps,
such as Splunk Enterprise Security and Splunk IT Service Intelligence, have
additional requirements and recommendations for the Splunk environment. For
example, Splunk Enterprise Security requires a dedicated search head cluster and
a minimum of 12 CPU cores per search head. Splunk IT Service Intelligence
requires a minimum of 16 CPU cores and 64 GB of RAM per search head45.
An indexer cluster is being designed with the following characteristics:
A. Zero peers can fail.
B. One peer can fail.
C. Three peers can fail.
D. Four peers can fail.
Explanation: Three peers can fail. This is the maximum number of search peers that can fail before data becomes unsearchable in the indexer cluster with the given characteristics. The searchability of the data depends on the Search Factor, which is the number of searchable copies of each bucket that the cluster maintains across the set of peer nodes1. In this case, the Search Factor is 3, which means that each bucket has three searchable copies distributed among the 10 search peers. If three or fewer search peers fail, the cluster can still serve the data from the remaining searchable copies. However, if four or more search peers fail, the cluster may lose some searchable copies and the data may become unsearchable. The other options are not correct, as they either underestimate or overestimate the number of search peers that can fail before data becomes unsearchable. Therefore, option C is the correct answer, and options A, B, and D are incorrect.
