A user has scheduled the maintenance window of an RDS DB on Monday at 3 AM. Which of the below
mentioned events may force to take the DB instance offline during the maintenance window?
A.
Enabling Read Replica
B.
Making the DB Multi AZ
C.
DB password change
D.
Security patching
Explanation:
Amazon RDS performs maintenance on the DB instance during a user-definable maintenance window. The
system may be offline or experience lower performance during that window. The only maintenance events that
may require RDS to make the DB instance offline are:
Scaling compute operations
Software patching. Required software patching is automatically scheduled only for patches that are security
and durability related. Such patching occurs infrequently (typically once every few months. and seldom requires
more than a fraction of the maintenance window.
D
Maintenance items require that Amazon RDS take your DB instance or DB cluster offline for a short time. Maintenance that require a resource to be offline include scale compute operations, which generally take only a few minutes from start to finish, and required operating system or database patching. Required patching is automatically scheduled only for patches that are related to security and instance reliability. Such patching occurs infrequently (typically once every few months) and seldom requires more than a fraction of your maintenance window.
