Discuss Amazon PAS-C01 Exam Topic 10 Question 12

A company hosts an SAP HANA database on an Amazon EC2 instance in the us-easi-1 Region. The company needs to implement a disaster recovery (DR) site in the us-west-1 Region. The company needs a cost-optimized solution that offers a guaranteed capacity reservation an RPO of less than 30 minutes and an RTO of less than 30 minutes.

When solution will meet these requirements?

ADeploy a single EC2 instance to support the secondary database in us-west with additional storage Use this secondary database instance to support QA and production Configure the primary SAP HANA database in us-east-1 to constantly replicate the data to the secondary SAP HANA database in us-west-t by using SAP HANA system replication with preload off During DR shut down the QA SAP HANA instance and restart the production services at the secondary site

BDeploy a secondary staging server on an EC2 instance in us-west-1 Use CloudEndure Disaster Recovery to replicate changes at the database level from us-east-1 to the secondary staging server on an ongoing basis During DR, initiate cutover increase the size of the secondary EC2 instance to match the primary EC2 instance and start the secondary EC2 instance

CSet up the primary SAP HANA database in us-east-1 to constantly replicate the data to a secondary SAP HANA database in us-west-1 by using SAP HANA system replication with preload on Keep the secondary SAP HANA instance as a hot standby that is ready to take over in case of failure

DCreate an SAP HANA database AMI by using Amazon Elastic Block Store (Amazon EBS) snapshots Replicate the database and log backup files from a primary Amazon S3 bucket in us-east-1 to a secondary S3 bucket m us-west-1 During DR launch the EC2 instance in us-west-1 based on AMIs that are replicated Update host information Download database and log backups from the secondary S3 bucket Perform a point-in-time recovery

Suggested Answer: C

VPC endpoints to ensure that traffic to and from the CloudWatch and EC2 services stays within the VPC. Additionally, an IAM policy is created to grant access to only the necessary actions, such as DescribeInstances and GetMetricStatistics, for all EC2 resources. This approach will provide secure monitoring of the SAP system while maximizing security and ensuring support from both SAP and AWS.

Wait, does preload really make that much of a difference?

James 12 months ago

A could work, but shutting down QA seems risky.

Marg 12 months ago

Not sure about D, sounds complicated for DR.

Jennifer 1 year ago

I think C is the best choice for hot standby.

Shawna 1 year ago

Option B seems solid for ongoing replication.

Annalee 1 year ago

I think option B could work too, but I’m not sure if increasing the instance size during DR meets the RTO requirement effectively.

Ty 1 year ago

I’m a bit confused about the differences between system replication and using CloudEndure. I feel like I need to review those concepts again.

Stefany 1 year ago

Option C sounds familiar; I think it was mentioned as a hot standby solution in one of our practice questions. It might be the right choice for quick failover.

Roslyn 1 year ago

I remember we discussed the importance of RPO and RTO in our last class, but I'm not entirely sure which option guarantees both under 30 minutes.

Omega 1 year ago

Okay, I think I've got this. The key is to identify which statements are true about User-Based Tunneling, not just about the overall solution design.

Cristen 1 year ago

Okay, let me think this through. The question is asking about a way to exclude search artifacts when creating a diag. Option D, --filter-searchstrings, sounds like it could be the right answer since it would filter out the search-related information.

Melvin 1 year ago

I think this is a pretty straightforward question. The key is to focus on the specific property mentioned - "system.content.maximumFileSizeLimit". Based on the options, it seems like this property controls the maximum file size for content created in the system, but the tricky part is figuring out the exact scope of where this limit applies.

I heard the company is also considering using a magic 8-ball to decide on the disaster recovery plan. Apparently, the results have been... 'Uncertain'.

Option D looks interesting, but relying on AMIs and backups from S3 seems a bit convoluted. I'd prefer a more streamlined solution like Option A or C.

Yeah, Option D might be a bit complex with AMIs and backups, I think simplicity is key for a DR solution.

Option A seems like a good choice for a cost-optimized solution with guaranteed capacity reservation and quick RPO and RTO.

Dortha 1 year ago

Option C is intriguing with the hot standby secondary HANA database, but I'm not sure if keeping the preload on is the most cost-effective approach. Maybe Option A would be a better fit overall.

Monte 1 year ago

I agree, Option A provides a comprehensive solution for the company's requirements. It's important to consider both cost-effectiveness and efficiency in a DR plan.

Yeah, Option A seems like a good choice for a guaranteed capacity reservation and quick RPO and RTO. It's a practical approach for disaster recovery.

Ollie 1 year ago

I think Option A could be a better fit overall, as it offers a cost-optimized solution with constant replication and the ability to shut down the QA instance during DR.

Krystina 1 year ago

Option C sounds good for high availability, but I agree that keeping the preload on may not be the most cost-effective choice.

Lilli 1 year ago

Yes, Option A offers a guaranteed capacity reservation and meets the RPO and RTO requirements.

Mary 1 year ago

I agree, Option A with constant replication and shutting down the QA instance during DR seems efficient.

I think Option A could work well for your situation.

Esteban 1 year ago

I'm not convinced that Option B is the best choice here. Using CloudEndure for replication might add an unnecessary layer of complexity, and increasing the instance size during DR might be a bit of a hassle.

Chauncey 2 years ago

Option A seems like a good choice, as it offers a cost-optimized solution with a guaranteed capacity reservation and the required RPO and RTO. The constant replication using SAP HANA system replication is a solid approach.

Dick 1 year ago

I agree, having the secondary database instance in us-west-1 for QA and production purposes makes it a comprehensive DR solution.

I'm leaning towards option D because it involves creating an AMI for easy recovery during a disaster.

Ashley 2 years ago

I disagree, I believe option C is better as it keeps the secondary database as a hot standby for quick failover.

Lawrence 2 years ago

I think option A could work because it involves constant replication and seems cost-effective.
