Re: AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 100

A: Missing encrypt/decrypt process. B: "Store the function in an Amazon S3 bucket" made meaningless. D: Amazon Elastic Block Store (Amazon EBS) for clone all of hard disk, CD/DVD. The context of question requires near real-time, it need save small parts, not a big part. --> Choose C (with S3, AWS Key Management Service - AWS KMS).

See https://docs.aws.amazon.com/kms/index.html . Decrypt process https://docs.aws.amazon.com/kms/latest/APIReference/API_Decrypt.html .

Re: AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 100

A. Manual - no no no!
B. External (python) library - no no no!
C. yeap.
D. S3 over EBS (see answer C)

Re: AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 100

I will go for D, as mentioned in the question ' an EC2 instance' , ' near real-time', 'LEAST operational overhead' all refer to EBS rather than S3.

Re: AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 100

near real time is the key that goes with EBS if we compare with S3 in this situation.
