A company has deployed a database in Amazon RDS for MySQL.Due to increased transactions, the database support team is reporting slow reads against the DB instance and recommends adding a read replica.
Which combination of actions should a solutions architect take before implementing this change?
(Choose two.)
Enable binlog replication on the RDS primary node.
Choose a failover priority for the source DB instance.
Allow long-running transactions to complete on the source DB instance.
Create a global table and specify the AWS Regions where the table will be available.
Enable automatic backups on the source instance by setting the backup retention period to a value other than 0.
From what I’ve heard, the answer is:
Allow long-running transactions to complete on the source DB instance.
