Exam AWS Certified Database - Specialty topic 1 question 41 discussion

Answer is C A. Use Amazon RDS automated snapshots and use AWS Lambda to copy the snapshot into another Region Automated snapshots are taken once per day only, RPO is 6 hours, so not an option B. Use Amazon RDS automated snapshots every 6 hours and use Amazon S3 cross-Region replication to copy the snapshot into another Region You can not take automated snapshots every 6 hours C. Create an AWS Lambda function to take an Amazon RDS snapshot every 6 hours and use a second Lambda function to copy the snapshot into another Region Only possible option D. Create a cross-Region read replica for Amazon RDS in another Region and take an automated snapshot of the read replica Not cost-effective, replica is the most expensive DR option.

Anser is C. D is not the most cost-effective A and B are not OK because automated snapshots are only once a day and you need one every 6 hours

C is the correct answer

It would be so much easier to use cross-region backup replication... https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_ReplicateBackups.html

Copying 200 Gb of snapshot every 6 hours across region will be costlier approach and ensuring lambda to finish job of coping 200gb snapshot with 15 mins is also not viable. So i think D is best choice.

c is right .

x A & B out: only automated snapshot per day allowed we need 4 C. Create an AWS Lambda function to take an Amazon RDS snapshot every 6 hours and use a second Lambda function to copy the snapshot into another Region (cost effective) D. Create a cross-Region read replica for Amazon RDS in another Region and take an automated snapshot of the read replica (costly)

Definitely (C) - also a question in the pfficial sample exam discussed by Stephen Maarek and Riyaz in their Udemy course

System snapshot can't fulfill 6 hours requirement. You need to control it by script https://aws.amazon.com/blogs/database/%C2%AD%C2%AD%C2%ADautomating-cross-region-cross-account-snapshot-copies-with-the-snapshot-tool-for-amazon-aurora/

Anyone planning for exam? We can share study material with each other, it would be beneficial for both. You can email me on "awsdbguru at gmail"

Correct Answer is ==>> C. any idea how much Q we will get in real exam from Q available here? anyone is preparing for this exam and want to do group study with us, comment with mail id.

https://aws.amazon.com/blogs/database/implementing-a-disaster-recovery-strategy-with-amazon-rds/ Automated Backup is daily, so 6 hour RPO is not possible. Only C is correct.

Answer is C. Reason for eliminating D is that RDS SQL SERVER does not support cross-region read replica and the question does not state which database engine used in RDS.

Agree with C

I think it is C.

Ans: D with key "operationally efficient". With option C, it is necessary to copy 200GB of data from one region to another every 6 hours.

A - wrong - I guess you cannot copy automated snapshots to another region. You must create a copy of automated snapshot in the same region first. B - wrong - automated snapshots are taken once in a day which alone wouldnt meet proposed RPO of 6hrs C - best answer for the requirement in hand. D - best option for cross region DR. However having a read-replica in another region is costlier than option C
