Troubleshooting Resource Policy Error
Question
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" suggests that the AWS IAM policy simulator is unable to retrieve the resource policy. This error can occur due to various reasons such as incorrect ARN, incorrect policy syntax, or insufficient permissions.
To resolve this error message, the following checks can be performed:
A. Check resource-based policy using AWS IAM Access Analyzer: AWS IAM Access Analyzer is a tool that analyzes resource policies to identify any potential issues such as resource-specific permissions and resource policy issues. The first check that can be performed is to use the IAM Access Analyzer to analyze the resource-based policy to identify any issues.
B. Check if conditional keys in the policy have the correct values specified: Conditional keys in a policy allow a condition to be applied to a specific statement in the policy. It is essential to verify if the conditional keys have the correct values specified in the policy, as it can impact the policy's behavior.
C. Check if ARN specified for the resource is correct: The Amazon Resource Name (ARN) is a unique identifier for Amazon Web Services resources. It is crucial to check if the ARN specified for the resource in the policy is correct. Any discrepancy in the ARN can cause the policy to fail.
D. Check if variables in the policy have correct values specified: Variables in a policy are placeholders that are replaced with actual values at runtime. It is essential to verify if the variables in the policy have the correct values specified, as any incorrect values can cause the policy to fail.
E. Check if the user running simulation has access to retrieve the resource policy: The IAM user running the policy simulator must have permission to retrieve the resource policy to perform the simulation. If the user does not have permission to retrieve the resource policy, the policy simulator will not be able to perform the simulation.
In summary, to resolve the error message "Cannot get the resource policy," the checks that can be performed include analyzing the policy using IAM Access Analyzer, verifying the ARN, conditional keys, and variables specified in the policy, and ensuring that the user running the simulation has permission to retrieve the resource policy.
