Guys let's Discuss Question 43. I would say the answer is C and here is my logic behind it. Both pilot light and warm standy technically give you the same RPO since we are talking about the database. They both offer some replication. So we can say they are equal when it comes to the 30s RPO. The main difference is the RTO. Warm Standby comes up in minutes which means its faster than pilot light when it comes to provisioning the applications etc. Pilot Standby provisions in 10s of minutes which is more than warm standby but I would like to believe its less than an hour. Otherwise, the documentation would have mentioned it takes an hour or hours like what it says for backup and restore. The question gives an RTO of 60 minutes which is 1 hour and I would like to believe this falls within the capabilities of Pilot Standby. So the Answer should be C since it's more cost-effective than warm standby as it provisions fewer resources for backup. Let's discuss this, you can refer to the documentation.
I agree, I think it would be C. AWS DRS is capable of achieving RPOs of seconds and RTOs of minutes, as per AWS documentation. Using that as a pilot light would definitely minimize cost.
RPO and RTO are defined as 10's of minutes in the documentation for Pilot Light, question talks about lowest cost option and also with 30 seconds RPO. Even though the services are provisioned in AWS they have to scale in case of failover on main systems for pilot light. With PRO being requested for 30 seconds I believe Pilot Light may not be the correct answer. Warm Standby has a small instance that is already running on cloud so traffic is already being directed and all it has to do is scale if necessary.
But the question is talking about an RTO of 60 mins. In Pilot Light the resources are idle. It's not like they need to be provisioned. From experience launching EC2 instances it doesn't take that long to provision them. I don't think Pilot Light will fail to meet the 60 minutes RTO. We can discuss further but that is my opinion. @g.vaibhavreddy2878 . I would stick with C I wish you the best in your exam if you are yet to write. I managed to pass about a month ago. keep practicing these questions they really helped me. @@gudvibes455
As you said, in option C, it satisfies RTO no doubt but, for RPO there is no replication mechanism set for data retrieval in case of data loss whereas, in option B there is a CDC stage to perform that.
if you google "Disaster Recovery (DR) Architecture on AWS, Part III: Pilot Light and Warm Standby" by Seth Eliot, you can find an AWS blog. it says "RPO for these strategies is similar, since they share a common data strategy." that means both Warm StandBy and Pilot Light have similar RPOs. Then the answer should be C, which is cheaper.
For question 50, how was "provide INDIVIDUAL and secure URLs" addressed? What would be the order of options A, D, F like which one is the first step and which one is the last?
@@tadikotadika8946 d talks about creating a wildcard certificate for your custom domain name. F is where you create the custom domain. So F comes before D I think
Thanks for making these videos. For Q42, Option D is a multi-az instance deployment with Aurora. Wont it come with read replicas by default that can help us avoid going with option C?
for q41: i tought I couldn't run php on S3. Could you clear it for me please ? sure would choose s3 over amplify in theis scenario but confused a little, thank you 💛
You are right, the answer is supposed to be E, s3 cannot run server side scripts like php, the article at 26:09 confirms this. I will put a correction in description. Thank you.
These Videos are great! I like the way how he explain the "How to Think", "How to Read" each questions, and it helped me to understand better. Thank you @sthithapragna
I'm so glad to hear that you've found the videos helpful! It's always rewarding to know that my explanations are making a positive impact. Thank you for your kind words and support.

Q41. ns --> S3 doesn't support server-side scripts, PHP is a server-side script. ( answer is A, C, E. ) not F
Yes, I already made the correction and added it in the description. ✌️
Amazing work. Love the way you explain
42. Oracle isnt supported with Multi-AZ DB clusters. Answer could be D.
I really appreciate all your efforts
Love the videos! Great information!!
Thank you, all the best

Thank You for the amazing videos. Is there a way to switch off the background music? It is very distracting.
Thanks for the video, but Q.43. the answer should be C (Pilot light) not B.
I HAVE A DOUBT REGARDING QUESTION NO.42: Are Multi-AZ DB clusters available for Oracle??
yes
32:39 .. SIR .. does aws sets up question even from their blog ?? .. i mean RTO/ RPO is out of syllabus ??? .. pls reply
For question 50, how was "provide INDIVIDUAL and secure URLs" addressed?

F, D and A is the sequence

Aurora does not support Oracle DB. It only supports MySQL and Postgres.

Hello, Do you have a word document include all the question please ?
I have a question regarding Q42. Complex queries can be read from read replicas, so why is C not the correct option?
C is the correct option. That's what the video says.
Great video.Can you not use music in the background? Thanks
Its removed in later videos. All the best

Are these 38 videos enough to cover the entire SA course? @sthithapragnakk
These should be more than enough, dont forget to do the quiz sets. All the best.
@@sthithapragnakk Sir, Are these questions enough to appear for the certification exam to get through? Please advise
