Reviewing answers

  1. Options A, B, and C are correct answers. Option D is not a Splunk feature.
  2. Option B, No. Splunk cannot monitor binary files. It is only able to monitor text data.
  3. Option B, Fishbucket, is the right answer. The Splunk Enterprise and the UF use seek pointers and CRCs to track the progress of file monitoring and avoid duplicate data indexing.
  4. Options A, B, C, and D all are functions of an SH.
  5. Option A is correct (True). Indexers store raw events, index files, and other metadata files for search processing.
  6. Option A is correct (True). Once the data is written to an index, it is immutable.
  7. Options B, C, and D are the correct answers. The UF is a data collection component.
  8. Option C is the right answer. The SHC-D deploys apps to all cluster members through the captain.
  9. Options A, B, and D are the correct answers. The LM stores the license file upon adding a license. Optionally, licenses are stackable, and pools can be created on the LM. License reports are available in the MC app, available in the LM instance.
