License Management practice questions

splunk list license

Why it fails: This is not a valid command.

splunk get license-info

Why it fails: This is not a valid command.

splunk status

Why it fails: This checks if services are running.

License pools only apply to search heads.

Why it fails: License pools are for indexers.

The indexers have not been restarted.

Why it fails: License settings are dynamic and do not always require a restart.

The indexers are using a trial license.

Why it fails: Trial licenses do not support pools.

30 days

Why it fails: Thirty days exceeds the actual warning period Splunk allows after a licence violation. It is tempting because a month sounds like a generous grace window, and would be correct if the documented interval were thirty days rather than the actual fourteen.

3 days

Why it fails: Three days is not the warning window Splunk grants before blocking search. It is tempting because short grace periods feel plausible for a licensing breach, and would be correct if the documented warning interval were three days rather than the actual fourteen.

7 days

Why it fails: Seven days is not the warning period before Splunk blocks search after a licence violation. It is tempting because a week is a common grace duration, and would be correct if the documented warning interval were seven days rather than the actual fourteen.

Distributed search is enabled by default.

Why it fails: Distributed search requires an Enterprise license.

The maximum daily indexing volume is increased.

Why it fails: The Free license has a strictly lower limit.

Data retention is extended to 90 days.

Why it fails: Retention is not managed by the license type.

Data indexing is halted.

Why it fails: Indexing continues during a violation.

Search is immediately disabled.

Why it fails: Search is not disabled on the first violation.

The Splunk service stops.

Why it fails: The service continues to run.

3

Why it fails: The limit is 5.

10

Why it fails: 10 is too high.

1

Why it fails: The first is a warning.

All user accounts are locked.

Why it fails: Accounts remain active.

Data ingestion is blocked immediately.

Why it fails: Indexing continues during violations.

The license key is automatically deleted.

Why it fails: The key remains installed.

It allows the admin to search during the period.

Why it fails: The grace period is about indexing connectivity, search is generally unaffected unless the master was also the search head.

It only applies to trial licenses.

Why it fails: It applies to all enterprise slaves.

It counts as a license violation.

Why it fails: It is a communication grace period, not a volume violation.

Universal Forwarders

Why it fails: UFs do not consume licenses.

Deployment Servers

Why it fails: Deployment servers are management nodes.

Pools only function on indexer clusters.

Why it fails: Pools work on standalone indexers too.

Each pool requires its own unique license file.

Why it fails: One license file covers the whole environment.

The total quota of all pools can exceed the total license volume.

Why it fails: Pools cannot exceed total license capacity.

splunk add licenser-localslave -master_uri https://<license_master>:8089 -pool FinancePool

Why it fails: The `add licenser-localslave` command is used on an indexer to point it to a license master, not on the license master to add an indexer to a pool. It also does not accept a `-pool` parameter. This command would not achieve the goal of adding the indexer to FinancePool.

splunk edit licenser-pools -name FinancePool -remove <indexer_hostname>

Why it fails: The `-remove` parameter removes an indexer from the pool, which is the opposite of what is needed. Using this command would not add the indexer and could disrupt existing pool membership if the indexer was already present.

splunk add licenser-pools -name FinancePool -slaves <indexer_hostname>

Why it fails: The `add licenser-pools` command is used to create a new license pool, not to add an indexer to an existing pool. Using this command would attempt to create a new pool named FinancePool, which already exists, resulting in an error. The correct command for adding an indexer to a pool is different.

Add the new indexer's IP address to the license master's server.conf file under the [license] stanza.

Why it fails: The license master does not maintain a list of indexers in server.conf. Instead, each indexer must be configured with the license master's URI. Adding the indexer's IP to the license master's configuration is not a valid method and will not cause the indexer to report usage.

Create a new license pool and assign the new indexer to it using the monitoring console.

Why it fails: License pools are used to allocate license volume to specific indexers, but they do not register an indexer with the license master. The indexer must first be configured to communicate with the license master. Creating a pool without that configuration will not solve the problem.

Restart the license master to force a license pool reassignment.

Why it fails: Restarting the license master will not register the new indexer because the indexer must be explicitly configured to point to the license master. The license master does not automatically discover indexers; the indexer must be told where to report. Without that configuration, a restart will not resolve the missing usage data.

No violation occurs because the second indexer was not configured to report to the license master.

Why it fails: This is actually what happens: if the second indexer is not configured to report to the license master, its indexing volume is not counted toward the license. Therefore, no violation is triggered. However, this is a misconfiguration that could lead to unlicensed usage, and the question asks what happens on the seventh day of exceeding the license volume, which would only occur if the volume were counted. Since the volume is not counted, this option describes the outcome, but it is not the correct answer to the question as posed because the question implies the license volume is exceeded.

Indexing stops immediately on the indexer that exceeded the license, and search remains available.

Why it fails: Splunk does not stop indexing when the license volume is exceeded; indexing continues to avoid data loss. Instead, a license violation is recorded, and after seven consecutive violation days, search is blocked. Stopping indexing is not the enforcement mechanism, so this option is incorrect for the scenario.

The license master automatically increases the license quota to accommodate the additional indexer.

Why it fails: Splunk licenses are not auto-scaling. The license quota is fixed by the license file and must be manually updated by the administrator. The license master does not adjust quotas based on indexing volume, so this option is definitively wrong.

On the search head, run splunk edit licenser-localslave -master_uri https://<license_master>:8089.

Why it fails: Search heads do not report license usage to the license master; only indexers consume license volume. Configuring the search head as a license slave is unnecessary and can cause configuration errors. The license master manages indexers, not search heads. This command is intended for indexers that need to report license usage.

On each indexer, install the same license file that is on the license master.

Why it fails: Indexers do not need their own copy of the license file when they are configured to use a license master. The license master centrally manages the license and distributes entitlements. Installing the license file on each indexer is unnecessary and can lead to confusion or conflicts. Only the license master requires the license file.

On the license master, configure a license pool for each indexer and assign the indexer to its own pool.

Why it fails: Creating a separate license pool for each indexer is not a requirement for basic license aggregation. License pools are optional and used to partition license volume among groups of indexers. For a standard distributed setup, a single default pool is sufficient. This action is not required and adds unnecessary complexity.

The license master must be a dedicated instance that does not index data or run other roles.

Why it fails: The license master can be a dedicated instance, but it is not required to be. In many deployments, the license master also functions as an indexer, search head, or other role. However, for large environments, a dedicated license master is recommended for performance and stability. This statement is not universally true.

License slaves report their license usage to the license master every 24 hours.

Why it fails: License slaves report usage more frequently than every 24 hours. They send daily license usage data, but also communicate with the license master on a regular basis to check for violations and updates. The reporting interval is not a full day; it is typically every few minutes for heartbeat and daily for usage aggregation.

Each license slave must have its own license file installed locally to function.

Why it fails: License slaves do not require individual license files. They obtain their license authorization from the license master. Only the license master needs the enterprise license file. This option misrepresents the distributed licensing model, where the master manages the license for all slaves.

The license master is in a 72-hour grace period, which resets after each violation.

Why it fails: The 72-hour grace period is a one-time period after a violation is detected, during which indexing continues but a violation is recorded. It does not reset after each violation, and it does not prevent violations from being counted. This option misrepresents how the grace period works.

The license master is configured to ignore violations for the first 30 days of operation.

Why it fails: Splunk does not have a built-in 30-day grace period for new license masters. The grace period is 72 hours and applies to license violations, not to new installations. This option is incorrect because there is no such configuration that suppresses violations for 30 days.

The indexers are pooling their license usage, and the pool has a higher limit than the global license.

Why it fails: License pools cannot have a higher limit than the total license volume. The sum of all pool sizes cannot exceed the total license. If the global license is exceeded, violations should still be triggered unless the pools are misconfigured, but that would not prevent violations entirely.

splunk set licenser-localslave -master_uri https://licensemaster:8089

Why it fails: The 'splunk set' command is not used for configuring the license master. The correct verb is 'edit'. 'splunk set' is used for other purposes, such as setting global configurations. Therefore, this command will not work to configure the license master URL on the indexer.

splunk edit licenser-localslave -master_uri https://licensemaster:8089 -auth admin:changeme

Why it fails: While the '-auth' parameter is sometimes used with Splunk CLI commands, it is not required for 'edit licenser-localslave' because this command modifies the local configuration and does not require authentication to the license master. Including '-auth' here is unnecessary and does not affect the command's function, but the command itself is correct. However, the question asks for the command to set the license master URL, and this option includes an extra parameter that is not needed, making it less precise than the correct answer.

splunk edit licenser -master_uri https://licensemaster:8089

Why it fails: The 'licenser' stanza is used on the license master itself, not on the indexer. To configure an indexer to report to a license master, the 'licenser-localslave' stanza is used. Using 'licenser' on an indexer would not set the license master URL correctly and could cause configuration errors.

splunk list licenser-pools --verbose

Why it fails: This command lists configured license pools and their member indexers, not violation events. It is useful when reviewing pool allocation during the audit, but it provides no count of violations over the past 30 days and cannot indicate whether search has been disabled, so it does not answer the question.

splunk show license-usage --days=30

Why it fails: There is no 'show' subcommand for licenser usage in the Splunk CLI; the valid verb is 'list'. Although the intent matches the scenario, this syntax fails immediately, so it cannot produce violation history. An administrator relying on it would get an error rather than the audit data needed to confirm search status.

splunk diag --license-history

Why it fails: The diag command collects diagnostic bundles for support, and '--license-history' is not a valid flag. Even a full diag bundle would not present a simple violation count for the 30-day window. This option confuses troubleshooting data collection with license auditing and would not deliver the required answer.

Run the CLI command splunk show license on the license master.

Why it fails: The command splunk show license displays license usage and pool information, but it does not show the license expiration date or the total licensed volume. To view expiration and volume, administrators should use the Splunk web interface under Settings > Licensing, or run splunk list licenses. The show license command is useful for monitoring current usage but not for checking license details.

Check the license_usage.log file on the indexers for expiration and volume details.

Why it fails: The license_usage.log file contains records of indexed volume per indexer, but it does not include license expiration date or total licensed volume. This log is used for auditing usage and troubleshooting violations. For license details, administrators should consult the license master's configuration or the Licensing page in Splunk Web.

Run the CLI command splunk list licenser on the license master.

Why it fails: The command splunk list licenser is not a valid Splunk CLI command. The correct commands for license management include splunk list licenses to display license details, splunk show license for usage, and splunk add licenses to add a new license. Using an invalid command will result in an error and not provide the needed information.

Enable the offline licensing feature with splunk enable offline-licensing on every indexer.

Why it fails: There is no offline-licensing enablement command in Splunk Enterprise licensing. Each Splunk instance has a local license file that can serve as a fallback only under specific conditions, but this command does not exist, so it would fail and leave indexers dependent on the unreachable license manager during the rebuild.

Convert each indexer to a standalone license manager by running splunk edit licenser-localslave -master_uri self.

Why it fails: Pointing an indexer at itself as its license manager breaks the distributed licensing model and would cause license count conflicts when the real manager returns. This command is used to repoint a slave, not to make an indexer self-sufficient, and it does not provide the clean fallback behavior needed for a temporary outage.

Add the license manager host to each indexer's server.conf as a license slave peer using the [license] stanza.

Why it fails: The [license] stanza in server.conf controls settings such as active_group and master_uri, not peer membership. Listing the license manager as a peer would not grant indexers any ability to index while the manager is unreachable, and misconfiguring this stanza risks startup problems, so this does not achieve the required continuity.
