A 911 PSAP is migrating NMS polling off SNMPv2c community strings. Which SNMPv3 security level best protects credentials and payload confidentiality for civic monitoring?
Select an answer to reveal the explanation.
Short Explanation
Community strings are shared secrets shouted across the room. SNMPv3 authPriv both proves who is talking and encrypts what they say—authentication plus privacy. That is the upgrade a PSAP wants when leaving v2c behind.
Full Explanation
SNMPv3 introduces users and security levels: noAuthNoPriv, authNoPriv, and authPriv. authPriv authenticates and encrypts SNMP messages, addressing cleartext community exposure in SNMPv2c. A private VRF reduces exposure but does not make encryption optional for many compliance-minded designs. ACLs on v2c help sourcing but are not cryptographic equivalents of authPriv.
