Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 764 discussion

I'm between B and C. Since RDS requires an additional configuration for PTR, it adds an operational overhead. So I will go with B. Aurora provides automated backup and point-in-time recovery, simplifying backup management and data protection. Continuous incremental backups are taken automatically and stored in Amazon S3, and data retention periods can be specified to meet compliance requirements. RDS provides the same but first, the users should set a retention period for these backups, allowing historical data recovery in case of accidental data loss or corruption, and point-in-time recovery (PITR) allows users to restore the database to any specific moment within the set retention period.

Answer is B. please see below article https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-pitr.html

AnswerB The problem with this question is that we do not have enough information. We can execute task with both AURORA or RDS DB. I will go with AURORA as it is Amazon Proprietary and is developed by AWS teams, hence we do not need to think about updates etc. as it is done by AWS teams.

B is the correct option.

B: Amazon Aurora is a fully managed relational database engine that’s compatible with both MySQL and PostgreSQL

PTR, it's Aurora

It's C. Strictly speaking, there is no AWS DB call Amazon Aurora "MySQL"

C. This option aligns with the requirements by keeping the web tier in public subnets, migrating the application tier to EC2 instances in private subnets to enhance security, and using Amazon RDS for MySQL in private subnets to meet the database requirements with minimal operational overhead. option A:While migrating the web tier and application tier to EC2 instances in private subnets minimizes exposure to the internet. option B:. Migrating the database tier to Amazon Aurora MySQL introduces changes to the database engine, which might require additional testing and adjustments to the application. Additionally, Aurora MySQL does not directly support point-in-time recovery; instead, it uses continuous backups and snapshots for data recovery.

Option A works better

Option B
