Which four statements about SNMP implementation on the Cisco Nexus 7000 Series switch are true? (Choose four.)
The correct answer is A. Cisco NX-OS supports one instance of the SNMP per virtual device context. B. By default, Cisco NX-OS uses the default VDC for SNMP. C. SNMP supports multiple MIB module instances and maps them to logical network entities. D. SNMP is VRF aware. You can configure SNMP to use a particular VRF to reach the SNMP. SNMP on Cisco Nexus 7000 Series switches operates per Virtual Device Context (VDC), with each VDC supporting a single SNMP instance that uses the default VDC by default, is VRF-aware, and supports multiple MIB module instances.

Why each option
SNMP on Cisco Nexus 7000 Series switches operates per Virtual Device Context (VDC), with each VDC supporting a single SNMP instance that uses the default VDC by default, is VRF-aware, and supports multiple MIB module instances.
Cisco NX-OS implements SNMP on a per-VDC basis, allowing for independent SNMP configurations and monitoring within each isolated virtual device context.
By default, if not explicitly configured otherwise, the SNMP instance within the Cisco NX-OS environment will operate out of the default VDC.
SNMP utilizes multiple Management Information Base (MIB) module instances to represent and map to various logical network entities and their operational data.
SNMP on Cisco Nexus 7000 Series switches is Virtual Routing and Forwarding (VRF) aware, enabling administrators to configure SNMP to use a specific VRF for reaching its managers, ensuring network segmentation.
Cisco NX-OS supports SNMP versions v1, v2c, and v3, not solely SNMP version 3.
SNMP is implemented per VDC, meaning each VDC can have its own SNMP instance, rather than a single instance for the entire physical switch.
Each VDC supports one SNMP instance, although that instance can handle multiple SNMP sessions from different management stations.
