A. B. C. D.A.
On an Expressway zone, media encryption can be configured using the Advanced Encryption Standard (AES) or can be disabled (force unencrypted). IPsec and Triple Data Encryption Standard (3DES) are not media encryption modes that can be configured on an Expressway zone.
AES is a symmetric-key encryption algorithm that is widely used for securing data. AES is considered to be a very secure encryption standard and is recommended for use in secure communication channels.
IPsec is a protocol suite used to encrypt IP traffic. IPsec can be used to encrypt both data and control traffic and provides secure communication over an untrusted network such as the Internet.
3DES is a symmetric-key encryption algorithm that uses a 56-bit key and applies the encryption algorithm three times to each data block. However, due to its shorter key length, 3DES is considered less secure than AES.
Force unencrypted allows media to flow without encryption. This mode is generally not recommended as it can lead to security vulnerabilities.
Therefore, the correct answer to the question is A. Advanced Encryption Standard.
