Exam AWS Certified Developer Associate topic 1 question 171 discussion

A. Restrict viewer access by using signed URLs: While signed URLs can be used to control access to content and provide additional security measures, they do not specifically address the requirement of encrypting customer data in transit. Signed URLs are more relevant for controlling access to specific resources rather than securing data in transit. C. Enable field-level encryption: Field-level encryption is a feature that allows specific fields within a response to be encrypted, but it does not directly address the requirement of encrypting customer data in transit. Field-level encryption focuses on protecting specific data fields at rest or during storage, not during transit. D. Enable automatic object compression: Automatic object compression is a feature that reduces the size of content transferred from CloudFront to viewers by compressing the objects. While it can improve performance and reduce bandwidth usage, it does not directly address the requirement of encrypting customer data in transit.
