A start-up firm is planning to use the Amazon S3 bucket to save all its user data.
Resource policy is planned to be applied to these Amazon S3 buckets.
To avoid any impact on users, the Operations Head has instructed the team to perform testing of resource policies before applying in production.
The Operations Team is using the AWS IAM policy simulator to perform testing on resource policy.
While testing, the operations team gets an error message as “Cannot get the resource policy”
What checks can be performed to resolve the error message? (Select TWO)

A. B. C. D. E.Correct Answers: C and E.
While testing resource-based policy using AWS IAM policy simulator, if there is an error as “Cannot get the resource policy”, the following needs to be checked.
ARN of the resource is correctly mentioned in the policy.
Users running the simulation should have access to the resource policy.
Option A is incorrect as resource-based policy can be tested using the AWS IAM policy simulator.
AWS IAM Access Analyzer will help to evaluate resources within AWS which are shared with external entities.
Option B is incorrect as defining incorrect conditional keys in the resource policy will not generate this error message.
Option D is incorrect as defining incorrect variables in the resource policy will not generate this error message.
For more information on AWS IAM, refer to the following URL,
https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_testing-policies.htmlThe error message "Cannot get the resource policy" indicates that there is an issue with retrieving the resource policy while testing the AWS IAM policy simulator. To resolve this error, there are a few checks that can be performed.
A. Check resource-based policy using AWS IAM Access Analyzer: AWS IAM Access Analyzer helps to identify resources that are shared with external principals, which could be a security risk. It can also help to identify potential issues with resource policies. The first check that can be performed is to verify the resource-based policy using the IAM Access Analyzer. This will help to identify any issues with the resource policy that could be causing the error.
B. Check if conditional keys in the policy have the correct values specified: Resource policies can contain conditions that allow or deny access based on certain criteria, such as IP address or time of day. One possible cause of the error could be that the conditional keys in the policy have incorrect values specified. Therefore, the operations team should verify that the conditional keys in the policy have the correct values specified.
C. Check if ARN specified for the resource is correct: An Amazon Resource Name (ARN) is a unique identifier for AWS resources. The ARN is used to specify the resource in the resource policy. It is possible that the error is occurring because the ARN specified in the resource policy is incorrect. Therefore, the operations team should check that the ARN specified for the resource is correct.
D. Check if variables in the policy have correct values specified: Resource policies can contain variables, such as ${aws:username} or ${aws:SourceIp}. These variables can be used to specify the principal or source IP address in the policy. One possible cause of the error could be that the variables in the policy have incorrect values specified. Therefore, the operations team should verify that the variables in the policy have the correct values specified.
E. Check if the user running simulation has access to retrieve the resource policy: The IAM user running the policy simulator may not have sufficient permissions to retrieve the resource policy. Therefore, the operations team should verify that the user running the simulation has access to retrieve the resource policy.
In summary, to resolve the error message "Cannot get the resource policy" while testing resource policies on Amazon S3 bucket, the Operations Team should check the resource-based policy using AWS IAM Access Analyzer, verify the conditional keys and variables in the policy, check the ARN specified for the resource and ensure that the user running the simulation has access to retrieve the resource policy.
