Which three statements about telemetry protocols and data collection are true? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
gNMI is a gRPC-based network management protocol that supports telemetry streaming.
gNMI is a gRPC-based protocol for streaming telemetry and managing network devices. Dial-out telemetry pushes data from the device to a collector. Telemetry can provide more granular data than SNMP. SNMP is still widely used for legacy monitoring. gNMI does not require CLI configuration for telemetry.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
gNMI is a gRPC-based network management protocol that supports telemetry streaming.
Why this is correct
Correct because gNMI (gRPC Network Management Interface) is designed for streaming telemetry and configuration management.
- ✓
In dial-out telemetry, the network device initiates the connection to the collector.
Why this is correct
Correct because dial-out (push) telemetry has the device send data to a pre-configured collector, reducing collector complexity.
- ✓
Telemetry can provide higher granularity and lower latency compared to SNMP polling.
Why this is correct
Correct because telemetry pushes data at high frequency or on-change, offering near real-time visibility.
- ✗
SNMP is the only protocol supported for telemetry data collection on Cisco IOS XE devices.
Why it's wrong here
Incorrect because IOS XE supports multiple telemetry protocols including gRPC, gNMI, and NetFlow, not just SNMP.
- ✗
gNMI requires the device to be configured with a CLI-based telemetry profile.
Why it's wrong here
Incorrect because gNMI subscriptions can be configured via YANG models and NETCONF/RESTCONF, not exclusively through CLI.
