Which caching mode does every write to the cache cause a synchronous write to the back-end
store?
A.
Refresh-Ahead Cache
B.
Write-Through Cache
C.
Write-Behind Cache
D.
Read-Through Cache
Explanation:
In a write-through cache, every write to the cache causes a synchronous write to the
backend store.
In this approach, the data is updated in the
backend data store, then the primary cache, all within the scope of the transaction.
Then the backup cache is also updated to maintain consistency of data.
