A. B. C. D.B.
In a mesh network, backhaul links are used to provide connectivity between mesh access points (MAPs) and the network infrastructure, such as a switch or router. As these links carry sensitive information, including user data and network control traffic, it is important to ensure that they are secured with appropriate encryption.
In terms of encryption, the most commonly used standards for wireless networks are Advanced Encryption Standard (AES) and Wired Equivalent Privacy (WEP). WEP is an older standard that is now considered to be insecure and easily hacked. Therefore, it is not recommended to use WEP for backhaul link encryption.
AES, on the other hand, is a more secure encryption standard that is commonly used for wireless network security. It is a symmetric encryption algorithm that uses a 128-bit block size and key length. The AES algorithm has been tested and validated by the National Institute of Standards and Technology (NIST), and it is widely considered to be a secure method for protecting wireless network traffic.
3DES, or Triple Data Encryption Standard, is another symmetric encryption algorithm that uses three rounds of encryption to provide additional security. However, it is an older standard that has been largely replaced by AES due to its slower performance and vulnerability to certain types of attacks.
In summary, the most appropriate level of encryption for mesh backhaul links is AES. Therefore, answer B is correct. Answer C (WEP) and answer D (3DES) are both incorrect. Hash, answer A, is not an encryption standard but a mathematical function used to verify the integrity of data.
