Exam AWS Certified DevOps Engineer - Professional DOP-C02 topic 1 question 177 discussion

Exam question from Amazon's AWS Certified DevOps Engineer - Professional DOP-C02
Question #: 177
Topic #: 1
[All AWS Certified DevOps Engineer - Professional DOP-C02 Questions]

A company has deployed a critical application in two AWS Regions. The application uses an Application Load Balancer (ALB) in both Regions. The company has Amazon Route 53 alias DNS records for both ALBs.

The company uses Amazon Route 53 Application Recovery Controller to ensure that the application can fail over between the two Regions. The Route 53 ARC configuration includes a routing control for both Regions. The company uses Route 53 ARC to perform quarterly disaster recovery (DR) tests.

During the most recent DR test, a DevOps engineer accidentally turned off both routing controls. The company needs to ensure that at least one routing control is turned on at all times.

Which solution will meet these requirements?

  • A. In Route 53 ARC, create a new assertion safety rule. Apply the assertion safety rule to the two routing controls. Configure the rule with the ATLEAST type with a threshold of 1.
  • B. In Route 53 ARC, create a new gating safety rule. Apply the assertion safety rule to the two routing controls. Configure the rule with the OR type with a threshold of 1.
  • C. In Route 53 ARC, create a new resource set. Configure the resource set with an AWS::Route53::HealthCheck resource type. Specify the ARNs of the two routing controls as the target resource. Create a new readiness check for the resource set.
  • D. In Route 53 ARC, create a new resource set. Configure the resource set with an AWS::Route53RecoveryReadiness::DNSTargetResource resource type. Add the domain names of the two Route 53 alias DNS records as the target resource. Create a new readiness check for the resource set.

Selected Answer: B
B is correct Option D is incorrect due to a few reasons: 1. No Automation for Report Copying: Unlike Option B, there's no mention of any automated process to copy the reports to the S3 bucket. It relies solely on configuring the S3 bucket as an artifact destination. Without automation, someone would have to manually manage the copying process, which is less efficient and prone to errors. 2. Expiration: While Option D mentions setting object expiration to 90 days, it doesn't specify how this would be achieved. S3 Lifecycle rules are typically used to manage object expiration, but there's no mention of setting up such a rule in this option.

A is correct: assertion rule to make sure that atleast on gate is always open. This rules are basically things that users cannot do or only allow to do B: This gating rule is basically an on-off swith for a set of ARCs. If there is a controller that we dont want to turn off, specify this rule. This rule might help us achive the goal of the question. However, this requires we specify the exact name of the controller that should not be turned off. Meanwhile, the question requires that any controller can be turned off but at least one must be up and running. Therefore, this is not the right option

C and D are irrelevant. They are about creating new resource

It's an assertion rule with ATLEAST threshold set to 1. So, A. Here is a reference: https://docs.aws.amazon.com/r53recovery/latest/dg/routing-control.safety-rules.html https://docs.aws.amazon.com/r53recovery/latest/dg/getting-started-cli-routing.html#getting-started-cli-routing.safety
