Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 251 discussion

D makes complete sense. Think about it, you can have sale of diffrent types of cars happening simultaneously. For ex, toyota might have its own queue. Since RDS sends notification to SNS. IT HAS TO BE D. :) https://docs.aws.amazon.com/lambda/latest/dg/services-rds.html https://docs.aws.amazon.com/lambda/latest/dg/with-sns.html

A. You can't use Lambda directly with RDS, RDS sends the notification to SNS which then can trigger a lambda. Take a look https://docs.aws.amazon.com/lambda/latest/dg/services-rds.html B. Same as A. C. The RDS event notifications sends the notification using SNS not SQS. D. Sounds about right. You Subscribe to an RDS event notification which sends to SNS topic, which is fanned out to multiple Amazon SQS queues. Here is the problem, why would we need multiple queues? I'd take B, let's say that the lambda function is triggered by the SNS sent by the RDS event notification. And why FIFO? Since, we need it to happen only once, "when an automobile is sold". What do you guys think?

D is correct

D is the answer

First Two option AWS Lamdba is not required to monitor DB update.

I dont think the question is asking us to update the targets? Hence Ans: D is an over kill. Write a Lambda code to update the targets? Simple solution should be A or B. Since a car is sold only once and DB is updated only once, it will trigger a lambda only once (No need for FIFO). Hence I prefer Ans: A over B.

Answer is D

I think D is right as per below link RDS event notifications are sent out to SNS. https://docs.aws.amazon.com/lambda/latest/dg/services-rds.html

https://aws.amazon.com/blogs/aws/queues-and-notifications-now-best-friends/

A is the Answer. RDS Event notification won't send notification in case of a data delete. https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Events.Messages.html You can always use lambda to configure multiple SQS for multiple target systems

Agree with D

ANS A: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/PostgreSQL-Lambda.html Invoking an AWS Lambda function from an RDS for PostgreSQL DB instance

Ans A: As of March 15th 2022, you can invoke an AWS Lambda function only from PostgreSQL engine in RDS but not from MySQL engine. The documentation is provided below: Invoking an AWS Lambda function from an RDS for PostgreSQL DB instance You can also invoke an AWS Lambda function from either MySQL or PostgreSQL engines in Aurora (NOTE: Aurora is different AWS service from RDS). The documentation for both is provided below: Invoking an AWS Lambda function from an Aurora PostgreSQL DB cluster Invoking a Lambda function from an Amazon Aurora MySQL DB cluster

RDS events are not for CURD operations. Follow below link. https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Events.overview.html You can subscribe to an event category for the following resources: DB instance DB snapshot DB parameter group DB security group RDS Proxy Custom engine version

event notification is NOT for update

D is correct. Please disregard my previous vote for A. – There is no way to directly trigger Lambda functions from Amazon RDS. – You can associate an SNS topic with Amazon RDS instance for notifications and then add that SNS topic as an event source to Lambda function https://docs.aws.amazon.com/lambda/latest/dg/services-rds.html – If you’re using AWS Aurora MySQL DB, you can invoke an AWS Lambda function from by calling the mysql.lambda_async procedure. https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraMySQL.Integrating.Lambda.html that is why I’m jumping from answer A to answer D ! 7 Reply Leave a Reply Your email address will not be published.
