Which two actions minimize the impact of the trusted NMS polling your network, such as high CPU utilization on network devices and network instability? (Choose two.)

Polling large SNMP tables such as the routing table, interface table, or ARP table causes spikes in CPU utilization on the device. Restricting polling to specific OIDs prevents NMS systems from walking these expensive tables and directly limits the processing overhead imposed on network devices.

Disabling unused OIDs and MIBs on the NMS reduces what the NMS can display, but it does not reduce the polling requests sent to or the processing burden placed on network devices.

Increasing the SNMP process priority would cause the SNMP process to preempt other critical processes, worsening CPU contention and potentially increasing instability rather than reducing it.

Associating SNMP community strings with ACLs ensures that only the trusted NMS IP addresses can query devices, preventing unauthorized or excessive polling from other hosts that could contribute to instability and resource exhaustion.

Unloading unused MIBs from network devices does not reduce the overhead of polling MIBs that are still active and being queried by the NMS.
