How a user can create an index in the Elasticsearch cluster?

And index can be easily created in the Elasticsearch cluster all you have to do is use the command PUT prior to the index name. You will be permitted to create the index, and you can also add multiple other indexes if you need. Once it is done, you have to apply the command POST before the index name.

Note: The above question is a very important question when it comes to Elasticsearch interview questions.
