What sets up an association between one or more MyISAM tables and the named key cache?

Solution (By Examveda Team)

This question is about how you connect tables in a MySQL database to a specific area of memory called the "key cache." This cache helps speed up how quickly your database can find information. Think of it like a quick lookup table.

Let's break down the options:

Option A: BEGIN
This starts a transaction, which is a group of database operations that are all treated as one unit. This is not related to key caching.

Option B: CACHE INDEX
This is the correct answer! The CACHE INDEX command is specifically designed to link your MyISAM tables (a type of table in MySQL) to the key cache. This means that the data used to quickly look up information in those tables will be stored in the key cache for faster access.

Option C: ALTER DATABASE
This command is used to change the structure or properties of an entire database, but not to directly control the key cache.

Option D: ALTER EVENT
This is used to modify scheduled events (like running a certain task at a specific time) within your database. It has nothing to do with key caching.

So, the answer is Option B: CACHE INDEX.
