Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 111 discussion

Answer is D as the "HIGHEST available" and less "operational complex" The "Amazon RDS for MySQL with Multi-AZ enabled" option excludes A and B The "Auto Scaling group" is more available and reduces operational complexity in case of incidents (as remediation it is automated) than just adding one more instance. This excludes C. C and D to choose from based on D over C since is configured

Using RDS Multi-AZ is suitable for high availability and using EC2 Auto Scaling Groups is suitable for operational overhead.

Ans D - extends the architecture rather than complicating it: Amazon MQ with active/standby brokers configured across two Availability Zones; Auto Scaling group for the consumer EC2 instances across two Availability Zones; Amazon RDS for MySQL with Multi-AZ enabled.

- Active MQ with active/standby - Auto scaling across 2 AZs - RDS with Multi AZ. These provide the highest availability and least complexity (using Amazon MQ, auto scaling and RDS, all managed services)

D is obviously the highest available.

Definitely it's D

D: Managed and auto-scaling, resilient and HA service for each tier. This is well-architected too.

Using Amazon MQ with active/standby brokers provides highly available message queuing across AZs. Adding an Auto Scaling group for consumer EC2 instances across 2 AZs provides highly available processing. Using RDS MySQL with Multi-AZ provides a highly available database. This architecture provides high availability for all components of the system - queue, processing, and database.

Ans is C - C. Option C uses Amazon MQ with active/standby brokers, adds an additional consumer EC2 instance, and uses Amazon RDS for MySQL with Multi-AZ enabled. Amazon RDS Multi-AZ automatically replicates your database to another AZ and provides automated failover. This ensures high availability for both the messaging system and the database. Option D- bring More scalabilty rather HA

HIGHEST availability. Definitely option D.

The key reasons are: Amazon MQ active/standby brokers across AZs for queue high availability Auto Scaling group with consumer EC2 instances across AZs for redundant processing RDS MySQL with Multi-AZ for database high availability This combines the HA capabilities of MQ, EC2 and RDS to maximize fault tolerance across all components. The auto scaling also provides flexibility to scale processing capacity as needed.

D is the correct answer. Using Amazon MQ with active/standby brokers provides highly available message queuing across AZs. Adding an Auto Scaling group for consumer EC2 instances across 2 AZs provides highly available processing. Using RDS MySQL with Multi-AZ provides a highly available database. This architecture provides high availability for all components of the system - queue, processing, and database.

Keyword Amazon RDS, has C and D. Then D has "Auto Scaling group", choose D.

D With 3 options with Amazon MQ --> A is odd one out / Then ASG with M-AZ was an easy choice

Amazon MQ with active/standby brokers configured across two AZ ensures high availability for the message broker. In case of a failure in one AZ, the other AZ's broker can take over seamlessly. Adding an ASG for the consumer EC2 instances across two AZ provides redundancy and automatic scaling based on demand. If one consumer instance becomes unavailable or if the message load increases, the ASG can automatically launch additional instances to handle the workload. Using RDS for MySQL with Multi-AZ enabled ensures high availability for the database. Multi-AZ automatically replicates the database to a standby instance in another AZ. If a failure occurs, RDS automatically fails over to the standby instance without manual intervention. This architecture combines high availability for the message broker (Amazon MQ), scalability and redundancy for the consumer EC2 instances (ASG), and high availability for the database (RDS Multi-AZ). It offers the highest availability with low operational complexity by leveraging managed services and automated failover mechanisms.

Correct answer D

to achieve ha + low operational complexity, the solution architect has to choose option D, which fulfill these requirements.
