SPLK-1003 Indexes And Data Management — 25 Questions

Question 1

Which configuration file is used to define volume-based storage?

Accepted Answer

volumes.conf. volumes.conf is the specific configuration file for defining volume paths and their size limits.

Answer

server.conf

Answer

indexes.conf

Answer

inputs.conf

Question 2

What happens to data when a bucket rolls to 'frozen'?

Accepted Answer

It is deleted by default.. By default, when a bucket rolls to frozen, it is deleted unless a coldToFrozenScript is configured.

Answer

It is archived to the coldPath.

Answer

It is moved to a read-only state.

Answer

It is moved to the warmPath.

Question 3

Which Splunk component is responsible for orchestrating the transition of buckets from warm to cold?

Accepted Answer

Indexer. The Indexer process, specifically the bucket rolling process, handles the movement of buckets based on the index configuration.

Answer

License Master

Answer

Search Head

Answer

Deployment Server

Question 4

You are configuring a new index for high-volume data. To optimize ingestion performance, where should you place the hot buckets?

Accepted Answer

On high-performance local storage (SSD).. Hot buckets should be placed on high-performance storage, such as SSDs, because they are constantly being written to.

Answer

On a network-attached storage (NAS) with high latency.

Answer

In the coldPath directory.

Answer

On the same partition as the OS.

Question 5

An administrator needs to manually move a bucket to frozen state immediately for compliance reasons. What is the best method?

Accepted Answer

Update the retention policy to 0 seconds and restart.. The 'splunk enable/disable/remove' commands don't support manual freezing; the 'splunk revert' or manual bucket removal is not supported, but modifying the frozenTimePeriodInSecs is the formal way to trigger a policy change.

Answer

Delete the bucket folder from the OS.

Answer

Rename the bucket folder to start with 'frozen'.

Answer

Use the 'splunk edit index' command.

Question 6

You need to ensure that Data Models are accelerated. Where are the acceleration summaries stored?

Accepted Answer

Within the index itself in a sub-directory.. Data model acceleration summaries are stored in the indexer where the data resides, specifically within the index's bucket structure.

Answer

In the system/bin directory.

Answer

On the Search Head in a separate index.

Answer

In the Splunk KV Store.

Question 7

A user reports that their search is failing to return data from 3 years ago, even though the retention policy is set to 5 years. What is the most likely cause?

Accepted Answer

The index reached the maxTotalDataSizeMB limit.. The frozenTimePeriodInSecs is the primary retention limit; if it is set correctly, check the maxTotalDataSizeMB, which might trigger rolling to frozen earlier if the disk fills up.

Answer

The buckets are in the warm state.

Answer

The index is corrupted.

Answer

The user does not have read access to the cold bucket.

Question 8

An administrator needs to move an existing index's raw data to a new storage location without losing searchability. What is the recommended approach?

Accepted Answer

Update homePath and coldPath in indexes.conf to the new volume paths.. The volume-based storage approach allows moving indexes by updating homePath and coldPath to point to new volumes defined in volumes.conf.

Answer

Rename the index directory in the OS.

Answer

Delete and recreate the index with the new path.

Answer

Use the 'splunk revert' command.

Question 9

You need to ensure that an index does not exceed 500GB of total disk space. Which configuration setting in indexes.conf should you modify?

Accepted Answer

maxTotalDataSizeMB. maxTotalDataSizeMB is the correct setting to limit the total size of an index on disk.

Answer

maxDataSize

Answer

frozenTimePeriodInSecs

Answer

homePath.maxDataSizeMB

Question 10

Which file in the index directory contains the bucket's metadata?

Accepted Answer

bucket.meta. The journal.gz and the corresponding .meta files contain the metadata for the events in the bucket.

Answer

rawdata

Answer

journal.gz

Answer

index.conf

Question 11

When configuring an index, which setting determines the directory where 'cold' buckets are stored?

Accepted Answer

coldPath. The coldPath setting in indexes.conf explicitly defines the location for cold data.

Answer

thawedPath

Answer

homePath

Answer

frozenPath

Question 12

What is the primary function of the 'thawed' bucket state?

Accepted Answer

It is used to store restored frozen data.. The thawed state is used to store data that has been manually restored from a frozen (archived) state.

Answer

It is the default state for new data.

Answer

It is for data that is being deleted.

Answer

It is a cache for warm buckets.

Question 13

A bucket in the 'warm' state is currently locked. What process is likely happening?

Accepted Answer

The bucket is being rolled.. During bucket rolling (from hot to warm or warm to cold), the bucket is temporarily locked to ensure data integrity during the file system move.

Answer

The bucket is being searched.

Answer

The bucket is being indexed.

Answer

The bucket is undergoing a summary rebuild.

Question 14

You want to prevent an index from growing beyond 10,000,000 events. Which setting is appropriate?

Accepted Answer

It is not possible to limit by event count via indexes.conf.. maxTotalDataSizeMB is for size, but maxHotSpanSecs or other settings do not limit by event count. However, maxWarmDBCount and maxHotBuckets can influence retention, but there is no direct 'maxEventCount' setting in indexes.conf. Therefore, you must use a scripted approach or external monitoring. Wait—actually, checking the docs, there is no event count limit. The best answer is that it cannot be done via indexes.conf.

Answer

maxTotalDataSizeMB

Answer

maxEventCount

Answer

maxBuckets

Question 15

When using the 'splunk cmd splunkd bucket-info' tool, what are you primarily investigating?

Accepted Answer

Bucket state and event boundaries.. This tool allows administrators to inspect the properties of individual buckets, such as size, state, and event counts.

Answer

Search performance metrics.

Answer

User authentication logs.

Answer

Indexer license usage.

Question 16

What is the effect of setting 'maxHotSpanSecs' to a very low value?

Accepted Answer

More frequent bucket rolling.. A low maxHotSpanSecs value causes buckets to roll more frequently, which increases the number of buckets and overhead.

Answer

Increased search performance.

Answer

Decreased disk usage.

Answer

Faster ingestion.

Question 17

Which Splunk GUI page provides a summary of all configured indexes and their current disk usage?

Accepted Answer

Settings > Data > Indexes. The 'Indexes' page under Settings > Data > Indexes provides a dashboard-style view of index status and usage.

Answer

Settings > Server Settings

Answer

Settings > Data > Inputs

Answer

Settings > Licensing

Question 18

What command is used to check the health and integrity of an index bucket?

Accepted Answer

splunk fsck. The 'splunk fsck' command is designed to perform file system checks on buckets.

Answer

splunk status

Answer

splunk check

Answer

splunk validate

Question 19

When should you use the 'volume' configuration in indexes.conf?

Accepted Answer

To manage shared storage limits across multiple indexes.. Volumes are used to group multiple indexes together to manage their shared storage capacity constraints.

Answer

To increase search speed.

Answer

To replicate data between indexers.

Answer

To encrypt index data.

Question 20

If a search head cluster member cannot access an indexer's bucket, what should you verify first?

Accepted Answer

The replication status and indexer clustering state.. Bucket access in a cluster is often related to the replication factor and the status of the bucket on the indexer peers.

Answer

The indexer's license status.

Answer

The OS version of the search head.

Answer

The search head's RAM.
