Possible Incorrect Question/Answer in AWS DevOps Professional Practice Exam #3

[Argyris Kefalas]

In the AWS Certified DevOps Engineer Professional Practice Exams DOP-C02 2026, under Review Mode → Review Mode Set 2, I noticed what appears to be a possible inconsistency in one of the questions.

for the question “A telecommunications company has a web portal that requires a cross-region failover. The portal stores its data in an Amazon Aurora database in the primary region (us-west-1) and the Parallel Query feature is also enabled in the database to optimize some of the I/O and computation involved in processing data-intensive queries. The portal uses Amazon Route 53 to direct customer traffic to the active region.

Which among the options below should be taken to MINIMIZE downtime of the portal in the event that the primary database fails?“

Its says that this answer is incorrect with this explanation “Configure an Aurora Global Database with a primary cluster in us-west-1 and a secondary cluster in the failover region. Set up a Route 53 health check and configure the Failover routing policy to automatically redirect traffic to the secondary region upon a primary database failure is incorrect because although Aurora Global Database is a valid AWS service for cross-region replication, it does not support the Aurora Parallel Query feature, which is explicitly stated as enabled in this scenario. Implementing Aurora Global Database would require disabling Parallel Query, making it architecturally incompatible with the portal’s existing database configuration.”

I tried to verify this statement in the official AWS documentation, but I couldn’t find any documentation stating that Aurora Global Database is incompatible with Aurora Parallel Query.

# A recomendation: It would be very helpfull if there was an ID attached to each question of the course. So that we can reference it easily without having to copy paste such long messages in the Forum.
