NEW QUESTION # 788

Answer: B,E
NEW QUESTION # 789
A company has multiple development teams. Each development team runs its own cloud development environment. Each development environment is isolated to its own AWS account.
All of the team AWS accounts belong to the same organization in AWS Organizations.
A development team federates into Account A. The development team must copy objects from Amazon S3 buckets that are in Account B and Account C to an S3 bucket that is in Account A.
Which solution will meet these requirements in the MOST operationally efficient way?
Answer: B
Explanation:
Configuring bucket policies in Accounts B and C to allow the development team's existing IAM role in Account A to read the source buckets provides direct cross-account access without requiring the team to assume roles in multiple accounts or manage additional identities. This minimizes ongoing operational overhead while keeping access tightly scoped to only the required buckets and actions.

NEW QUESTION # 791
A developer uses an AWS Lambda function to process video files. The input files are always between 4.5 GB and 5 GB in size. The output files are always between 1.5 GB and 2 GB in size.
The Lambda function has 8.000 MB of ephemeral storage. Both input and output files are written to /tmp on the Lambda function.
Sometimes the invocations result in an "[ERROR] OSError: [Error 28] No space left on device" error and a failed function execution.
The developer must prevent the error from occurring.
Which solution will meet this requirement?
Answer: A
Explanation:
The error [Error 28] No space left on device occurs because the total size of input (up to 5 GB) and output (up to 2 GB) files can exceed the 8,000 MB (≈7.8 GB) of ephemeral /tmp storage available to the Lambda function. To prevent this, increase the ephemeral storage to 10,240 MB (10 GB), which is the current maximum supported size, ensuring sufficient space for temporary file processing.
NEW QUESTION # 792
A developer has written the following IAM policy to provide access to an Amazon S3 bucket:
Which access does the policy allow regarding the s3:GetObject and s3:PutObject actions?
Answer: A
Explanation:
The IAM policy shown in the image is a resource-based policy that grants or denies access to an S3 bucket based on certain conditions. The first statement allows access to any S3 action on any object in the "DOC- EXAMPLE-BUCKET" bucket when the request is made over HTTPS (the value of aws:SecureTransport is true). The second statement denies access to the s3:GetObject and s3:PutObject actions on any object in the
"DOC-EXAMPLE-BUCKET/secrets" prefix when the request is made over HTTP (the value of aws:
SecureTransport is false). Therefore, the policy allows access on all objects in the "DOC-EXAMPLE- BUCKET" bucket except on objects that start with "secrets". Reference: Using IAM policies for Amazon S3
