Answer:
Hence the answer is Option A Encrypt all communication with TLS 1 3.
Step-by-step explanation:
Transportation Layer Security (TLS 1 3)---->TLS stands for Transport Layer Security and is the successor to SSL (Secure Sockets Layer). TLS provides secure communication between web browsers and servers. The connection itself is secure because symmetric cryptography is used to encrypt the transmitted data.
SNMPv3 Security with 256 bit AES encryption is not available for all devices. The net-snmp agent does not support AES256 with SNMPv3.so it is not the correct option.
The best choice is an option a because TLS 1 3 because,
TLS version 1 3 helped in removing all the insecure features such as:
SHA-1
RC4
DES
3DES
AES-CBC
