The configuration in Option B likely involves setting up an IP access list that permits only the NMS server IP address (10.15.2.19) and configuring SNMP server view with read-only permissions, ensuring minimum permission levels and secure communication. This aligns with the requirements for encrypted and password-protected communication using secure algorithms, while also restricting access to the specified NMS server12.
