Under which condition does ICMP polling for status and response time work according to the material?

• A. SNMP disabled and ICMP enabled on the device
• B. SNMP enabled and ICMP enabled on the device
• C. SNMP disabled and ICMP disabled
• D. ICMP is optional and can always poll

Answer: (A)

ICMP polling works when the device is reachable via ICMP, meaning ICMP must be enabled on the device. The material indicates that SNMP should be disabled for this polling path to be used, so the monitoring engine relies on ICMP Echo requests to determine status and measure round‑trip time without SNMP interference. If both SNMP and ICMP are disabled, there’s no polling path. If ICMP is optional or always allowed regardless of configuration, that wouldn’t reflect the required setup described. Therefore, the condition is SNMP disabled and ICMP enabled on the device.
