Which of the following accurately describes HTTP Event Collector indexer acknowledgement?
https://docs.splunk.com/Documentation/Splunk/8.2.2/Data/AboutHECIDXAck
- Section: About channels and sending data
Sending events to HEC with indexer acknowledgment active is similar to sending them with the setting off. There is one crucial difference: when you have indexer acknowledgment turned on, you must specify a channel when you send events. The concept of a channel was introduced in HEC primarily to prevent a fast client from impeding the performance of a slow client. When you assign one channel per client, because channels are treated equally on Splunk Enterprise, one client can't affect another. You must include a matching channel identifier both when sending data to HEC in an HTTP request and when requesting acknowledgment that events contained in the request have been indexed. If you don't, you will receive the error message, 'Data channel is missing.' Each request that includes a token for which indexer acknowledgment has been enabled must include a channel identifier, as shown in the following example cURL statement, where <data> represents the event data portion of the request
When are knowledge bundles distributed to search peers?
'The search head replicates the knowledge bundle periodically in the background or when initiating a search. ' 'As part of the distributed search process, the search head replicates and distributes its knowledge objects to its search peers, or indexers. Knowledge objects include saved searches, event types, and other entities used in searching accorss indexes. The search head needs to distribute this material to its search peers so that they can properly execute queries on its behalf.'
In this source definition the MAX_TIMESTAMP_LOOKHEAD is missing. Which value would fit best?
Event example:
https://docs.splunk.com/Documentation/Splunk/6.2.0/Data/Configuretimestamprecognition
'Specify how far (how many characters) into an event Splunk software should look for a timestamp.' since TIME_PREFIX = ^ and timestamp is from 0-29 position, so D=30 will pick up the WHOLE timestamp correctly.

An organization wants to collect Windows performance data from a set of clients, however, installing Splunk
software on these clients is not allowed. What option is available to collect this data in Splunk Enterprise?
'The Splunk platform collects remote Windows data for indexing in one of two ways: From Splunk forwarders, Using Windows Management Instrumentation (WMI). For Splunk Cloud deployments, you must use the Splunk Universal Forwarder on a Windows machines to montior remote Windows data.'
