You can only poll status and response time using only ICMP when SNMP is disabled and ICMP is enabled on the device.

You can only poll status and response time using only ICMP when SNMP is disabled and ICMP is enabled on the device.

• A. True
• B. False
• C. Only if SNMP is enabled
• D. Only if SNMP is disabled

Answer: (A)

Focusing on what ICMP can do shows why this is true: ICMP is the protocol used by ping to test reachability and to measure how long a round-trip takes. If SNMP is turned off, you lose SNMP-based polling, but that doesn’t stop you from using ICMP to check whether the device is reachable (status) and to gauge its response time (latency). As long as ICMP is enabled on the device and network paths allow ICMP traffic, you can obtain both the status and the response time without needing SNMP. In real networks, some devices or firewalls may block ICMP, which can affect these measurements, but the capability itself remains valid whenever ICMP is allowed and enabled.
