Which solution will meet these requirements?
Create multiple S3 bucket polices by using each VPC endpoint ID that have the aws:SourceVpce value in the StringNotEquals condition.
Create a single S3 bucket policy that has the aws:SourceVpc value and in the StringNotEquals condition to use VPC ID.
Create a single S3 bucket policy that has the aws:SourceVpce value and in the StringNotEquals condition to use vpce*.
Create a single S3 bucket policy that has multiple aws:sourceVpce value in the StringNotEquals condition. Repeat for all the VPC endpoint IDs.
Explanations:
Creating multiple S3 bucket policies for each VPC endpoint ID with theaws:SourceVpcecondition is unnecessary and inefficient. This approach would require managing several policies, increasing complexity and maintenance overhead. Instead, a single policy can handle all necessary VPC endpoints.
Usingaws:SourceVpcin the policy restricts access based on the VPC ID rather than the specific VPC endpoints. This does not fulfill the requirement of restricting access to only those users accessing via the specified VPC endpoints.
While usingaws:SourceVpceis appropriate, specifyingvpce*is overly broad and will include all VPC endpoints, not just the desired ones. This means users could potentially access the S3 bucket through other VPC endpoints that are not intended, violating the requirement of exclusive access through specified endpoints.
This option correctly creates a single S3 bucket policy that includes multipleaws:SourceVpcevalues in theStringNotEqualscondition. By listing all relevant VPC endpoint IDs, access is restricted solely to those endpoints, fulfilling the requirement effectively and efficiently.
I strategize that the answer is:
Create a single S3 bucket policy that has multiple aws:sourceVpce value in the StringNotEquals condition. Repeat for all the VPC endpoint IDs.
