The default bandwidth limit in the Splunk Universal Forwarder is set to 256 KBps. This setting is in place to prevent the forwarder from overwhelming network resources, and it can be adjusted as necessary based on the deployment's specific needs.

In Splunk Cloud, you can install apps via self-service, which allows you to install certain approved apps without involving Splunk Support. This self-service capability is provided for apps that have already been vetted and approved for use in the Splunk Cloud environment.

Option A typically requires support involvement because premium apps often need licensing or other special considerations.

Option B might involve the Request Install button, but some apps might still require vetting or support approval.

Option D is incorrect because apps that have not gone through the vetting process cannot be installed via self-service and would require Splunk Support for evaluation and approval.

The regex replacement processor is part of the parsing stage in Splunk's data ingestion pipeline. This stage is responsible for handling data transformations, which include applying regex replacements.

D. Parsing pipeline is the correct answer. The parsing pipeline is where initial data transformations, including regex replacement, occur before the data is indexed. This stage processes events as they are parsed from raw data, including applying any regex-based modifications.

transforms.conf is used for various advanced data processing tasks in Splunk, including:

Per-Event Sourcetype: Dynamically assigning a sourcetype based on event content.

Per-Event Host Name: Dynamically setting the host field based on event content.

Per-Event Index Routing: Directing specific events to different indexes based on their content.

Option B correctly identifies these common uses of transforms.conf.

The acceptFrom parameter is used in Splunk to specify which IP addresses or DNS names are allowed to send data to a Splunk instance. The supported formats include IPv4, IPv6, CIDR notation, and DNS names.

B. IPv4, IPv6, CIDRs, DNS names is the correct answer. These are the valid formats that can be used with the acceptFrom argument. Wildcards are not supported in acceptFrom parameters for security reasons, as they would allow overly broad access.

In Splunk, when ingesting logs such as an Apache access log, the time zone for each event is typically determined by the time zone indicator present in the raw event data itself. In the log snippet you provided, the time zone is indicated by -0400, which specifies that the event's timestamp is 4 hours behind UTC (Coordinated Universal Time).

Splunk uses this information directly from the event to properly parse the timestamp and apply the correct time zone. This ensures that the event's time is accurately reflected regardless of the time zone in which the Splunk instance or forwarder is located.

Splunk Cloud Reference: For further details, you can review Splunk documentation on timestamp recognition and time zone handling, especially in relation to log files and data ingestion configurations.

The followTail attribute in inputs.conf controls how Splunk processes existing content in a monitored file.

D. Prevents pre-existing content in a file from being ingested: This is the correct answer. When followTail = true is set, Splunk will ignore any pre-existing content in a file and only start monitoring from the end of the file, capturing new data as it is added. This is useful when you want to start monitoring a log file but do not want to index the historical data that might be present in the file.

A. Pauses a file monitor if the queue is full: Incorrect, this is not related to the followTail attribute.

B. Only creates a tail checkpoint of the monitored file: Incorrect, while a tailing checkpoint is created for state tracking, followTail specifically refers to skipping the existing content.

C. Ingests a file starting with new content and then reading older events: Incorrect, followTail does not read older events; it skips them.

These answers align with Splunk's best practices and available documentation on managing and configuring Splunk environments.

The correct SEDCMD setting to mask the credit card numbers, ensuring that the masked version replaces each digit with an "x" character, is Option A.

The SEDCMD syntax works as follows:

s/ starts the substitute command.

(?cc_num=\d{7})\d{9}/ matches the specific pattern of the credit card number in the logs.

\1xxxxxxxxx replaces the matched portion with the first captured group (the first 7 digits of the cc_num), followed by 9 "x" characters to mask the remaining digits.

/g ensures that the substitution is applied globally, throughout the string.

Thus, Option A correctly implements this requirement.

In Splunk Cloud, when there is a need for a change request that might involve modifying settings, upgrading, or other actions requiring Splunk Support, the process typically requires submitting a support case.

D. Any person with the appropriate entitlement: This is the correct answer. Any individual who has the necessary permissions or entitlements within the Splunk environment can submit a support case. This includes administrators or users who have been granted the ability to engage with Splunk Support. The request does not necessarily have to come from a Certified Splunk Cloud Administrator or the infrastructure owner; rather, it can be submitted by anyone with the correct level of access.

For input apps that are not permitted on Splunk Cloud, the recommended place to deploy them is on a Universal Forwarder or Heavy Forwarder. These forwarders handle data collection and preprocessing before sending the data to Splunk Cloud. This setup allows organizations to leverage apps and configurations that are not supported directly in the cloud environment.
