Discuss Amazon DOP-C02 Exam Topic 3 Question 18

A company is examining its disaster recovery capability and wants the ability to switch over its daily operations to a secondary AWS Region. The company uses AWS CodeCommit as a source control tool in the primary Region.

A DevOps engineer must provide the capability for the company to develop code in the secondary Region. If the company needs to use the secondary Region, developers can add an additional remote URL to their local Git configuration.

Which solution will meet these requirements?

ACreate a CodeCommit repository in the secondary Region. Create an AWS CodeBuild project to perform a Git mirror operation of the primary Region's CodeCommit repository to the secondary Region's CodeCommit repository. Create an AWS Lambda function that invokes the CodeBuild project. Create an Amazon EventBridge rule that reacts to merge events in the primary Region's CodeCommit repository. Configure the EventBridge rule to invoke the Lambda function.

BCreate an Amazon S3 bucket in the secondary Region. Create an AWS Fargate task to perform a Git mirror operation of the primary Region's CodeCommit repository and copy the result to the S3 bucket. Create an AWS Lambda function that initiates the Fargate task. Create an Amazon EventBridge rule that reacts to merge events in the CodeCommit repository. Configure the EventBridge rule to invoke the Lambda function.

CCreate an AWS CodeArtifact repository in the secondary Region. Create an AWS CodePipeline pipeline that uses the primary Region's CodeCommit repository for the source action. Create a Cross-Region stage in the pipeline that packages the CodeCommit repository contents and stores the contents in the CodeArtifact repository when a pull request is merged into the CodeCommit repository.

DCreate an AWS Cloud9 environment and a CodeCommit repository in the secondary Region. Configure the primary Region's CodeCommit repository as a remote repository in the AWS Cloud9 environment. Connect the secondary Region's CodeCommit repository to the AWS Cloud9 environment.

Suggested Answer: A

The best solution to meet the disaster recovery capability and allow developers to switch over to a secondary AWS Region for code development is option A. This involves creating aCodeCommit repositoryin the secondary Region and setting up anAWS CodeBuild projectto perform a Git mirror operation of the primary Region's CodeCommit repository to the secondary Region's repository. AnAWS Lambda functionis then created to invoke the CodeBuild project.Additionally, anAmazon EventBridge ruleis configured to react to merge events in the primary Region's CodeCommit repository and invoke the Lambda function12.This setup ensures that the secondary Region's repository is always up-to-date with the primary repository, allowing for a seamless transition in case of a disaster recovery event1.

Not sure about D, seems a bit complicated for just a remote setup.

Brock 11 months ago

I’m leaning towards C, it sounds more streamlined.

Glenn 11 months ago

Wait, why not just use CodePipeline for this?

Barbra 11 months ago

I think B is a better choice, S3 is super reliable!

Rosio 12 months ago

Option A seems solid with the CodeBuild and Lambda setup.

Lili 12 months ago

I feel like option C could work too since it mentions CodePipeline, but I'm not sure about the Cross-Region stage part.

Roxanne 1 year ago

I'm a bit confused about whether using S3 in option B is necessary. I thought CodeCommit could handle the mirroring directly?

Rashad 1 year ago

I think option A sounds familiar because it involves EventBridge and Lambda, which we practiced in a similar scenario.

Kenny 1 year ago

I remember we discussed the importance of having a mirror setup for CodeCommit, but I'm not sure if using CodeBuild is the best approach here.

Paris 1 year ago

I feel pretty confident about this. I've worked with similar disaster recovery setups before, so I think I can apply that experience here. I'll just need to double-check that I'm meeting all the requirements.

Golda 1 year ago

This is a tricky one. There are a lot of moving parts, and I want to make sure I don't miss any important details. I'll need to think through each option carefully and consider the pros and cons.

Kami 1 year ago

Hmm, I'm a bit unsure about the details here. I'll need to carefully read through the question again and make sure I understand all the different components involved.

Lucy 1 year ago

This seems like a pretty straightforward question. I think I have a good handle on the key requirements and can work through this step-by-step.

Laurena 1 year ago

Okay, I think I've got a solid strategy for this. The key is setting up the right AWS services to mirror the primary CodeCommit repo to the secondary Region. I'll focus on the specific steps needed to make that happen.

Merissa 1 year ago

This looks like a pretty straightforward question on integrating Spark with SageMaker. I'm confident I can handle this one.

Earleen 1 year ago

I'm a bit confused here. I know UML is a modeling language, but I'm not sure how it aligns with the IT4IT Service Lifecycle Data Object. I'll have to read the question more closely.

Lavina 1 year ago

This one seems straightforward. I'd go with HTTPS since it's the protocol used for secure web transactions.

Elmira 1 year ago

Okay, I think I've got this. The access list is restricting the BGP neighborships, so the correct answer is C - the router cannot form BGP neighborships with any device that is matched by the access list named "BGP".

Gaynell 2 years ago

I still prefer Option A because it specifically addresses the need for mirroring the CodeCommit repository for disaster recovery purposes.

Bernardo 2 years ago

That's true, Alease. Option C does involve using CodeArtifact, which could provide a reliable method for storing code in the secondary Region.

Alease 2 years ago

I'm not sure. Option C also looks like a good solution with CodePipeline and CodeArtifact involved. It could be a viable option as well.

Gaynell 2 years ago

I agree with Bernardo. Option A seems to be the most efficient way to ensure the company can develop code in the secondary Region.

Bernardo 2 years ago

I think option A is the best solution because it involves creating a CodeCommit repository in the secondary Region and using CodeBuild to mirror the repository.

Gertude 3 years ago

Ha, yeah, the CodeArtifact approach is a bit like using a bazooka to kill a fly. I think we can stick with the good ol' CodeCommit mirroring in option A.

Edelmira 3 years ago

I agree, option A looks like the best fit. Although, I do wonder if the S3 bucket approach in option B might be a bit simpler to implement. Hmm, decisions, decisions.

Anna 3 years ago

Alright, I think we've got a consensus on option A. Let's go with that and hope the examiners don't try to trick us with any sneaky follow-up questions!

Fingers crossed that the exam questions are straightforward!

Royce 2 years ago

↳ replying to Anna

Agreed, understanding the architecture is key to implementing it correctly.

Karan 3 years ago

↳ replying to Anna

Let's make sure we are familiar with each component and its role in the solution.

Arlen 3 years ago

↳ replying to Anna

It's always good to be prepared for any scenario.

Miriam 3 years ago

↳ replying to Anna

The combination of CodeCommit, CodeBuild, Lambda, and EventBridge is solid.

Whitney 3 years ago

↳ replying to Anna

I agree, it covers all the necessary steps for disaster recovery.

Nu 3 years ago

↳ replying to Anna

Option A seems like the most complete solution.

Tenesha 3 years ago

Ooh, option C with the CodeArtifact repo is an interesting twist. That could provide an extra layer of redundancy, but might be overkill for this scenario.
