The most probable cause is that you have not allowed the Lambda functions to have the appropriate permissions on the S3 bucket to make the relevant changes.

Option A is invalid because this is more of a permission instead of a configuration rule issue.

Option C is invalid because changing the language will not be the core solution.

Option D is invalid because you don't necessarily need to use the API gateway service

This is mentioned clearly as a use case for S3 cross-region replication

You might configure cross-region replication on a bucket for various reasons, including the following:

• Compliance requirements - Although, by default Amazon S3 stores your data across multiple geographically distant Availability Zones, compliance requirements might dictate that you store data at even further distances. Cross-region replication allows you to replicate data between distant IAM Regions to satisfy these compliance requirements.

Option A is invalid because Multi-AZ cannot be used to S3 buckets

Option B is invalid because copying it to an EBS volume is not a recommended practice

Option C is invalid because creating snapshots is not possible in S3

The IAM Documentation mentions the following

The IAM Documentation mentions the following

OIDC identity providers are entities in IAM that describe an identity provider (IdP) service that supports the OpenID Connect (OIDC) standard. You use an OIDC identity provider when you want to establish trust between an OlDC-compatible IdP—such as Google, Salesforce, and many others—and your IAM account This is useful if you are creating a mobile app or web application that requires access to IAM resources, but you don't want to create custom sign-in code or manage your own user identities

Option A is invalid because in the security groups you would not mention this information/

Option C is invalid because SAML is used for federated authentication

Option D is invalid because you need to use the OIDC identity provider in IAM

For more information on ODIC identity providers, please refer to the below Link:

https://docs.IAM.amazon.com/IAM/latest/UserGuide/id roles providers create oidc.htmll

The correct answer is: Create an OIDC identity provider in IAM

The policy consists of 2 statements, one is the allow for the user mark to the bucket and the next is the deny policy for all other users. The deny permission will override the allow and hence all users will not have access to the bucket.

Options A,B and D are all invalid because this policy is used to deny all access to the bucket mybucket

For examples on S3 bucket policies, please refer to the below Link:

http://docs.IAM.amazon.com/AmazonS3/latest/dev/example-bucket-policies.htmll

The correct answer is: It will deny all access to the bucket mybucket
