A healthcare customer requested that SNMP traps must be sent over the MPLS Layer 3...

SNMPv3 is recommended as it supports authentication and encryption, protecting SNMP traffic even across service provider MPLS VPN backbones.

Healthcare environments require strong privacy and compliance (e.g., HIPAA), making SNMPv3 the correct protocol.

Why other options are incorrect:

B and C: Syslog is unrelated to SNMP traps.

D: SNMPv2 lacks security (unencrypted community strings).

E: SSH secures CLI access but not SNMP.
