The correct choice is Base64 format, which is used by applications to encode binary values for processing in DynamoDB. Base64 encoding converts binary data into a text representation, which makes it easier to handle and transmit over various platforms that may not support raw binary data. This is particularly important because many data formats and communication protocols are optimized for textual data rather than binary. DynamoDB supports storing binary data, such as images or other non-text files. To effectively manage and interact with this binary data, the Base64 encoding ensures that it can be safely transmitted and processed without loss or corruption. It encodes the binary information into a string format composed of ASCII characters, thus allowing systems that may not be able to process raw binary data to still work with it effectively. The other options do not apply to the encoding method used in DynamoDB. Basic36, Base54, and Basic24 formats do not exist as recognized standards for encoding binary data, making them irrelevant to this context. Hence, Base64 is the correct and most commonly used format for encoding binary values in DynamoDB interactions.
