A pharmaceutical company’s drug search API is using an Amazon Neptune DB cluster.A bulk uploader process automatically updates the information in the database a few times each week.A few weeks ago during a bulk upload, a database specialist noticed that the database started to respond frequently with aThrottlingException error.The problem also occurred with subsequent uploads.The database specialist must create a solution to prevent ThrottlingException errors for the database.The solution must minimize the downtime of the cluster.
Which solution meets these requirements?
Create a read replica that uses a larger instance size than the primary DB instance. Fail over the primary DB instance to the read replica.
Add a read replica to each Availability Zone. Use an instance for the read replica that is the same size as the primary DB instance. Keep the traffic between the API and the database within the Availability Zone.
Create a read replica that uses a larger instance size than the primary DB instance. Offload the reads from the primary DB instance.
Take the latest backup, and restore it in a DB cluster of a larger size. Point the application to the newly created DB cluster.
I opine that the answer is:
Create a read replica that uses a larger instance size than the primary DB instance. Fail over the primary DB instance to the read replica.
If memory serves me right, the answer is:
Create a read replica that uses a larger instance size than the primary DB instance. Fail over the primary DB instance to the read replica.
