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
✓
Syslog messages can be used as a form of telemetry to report events and state changes.
Telemetry can be collected via SNMP (pull), Syslog (push), and model-driven telemetry (push). SNMP polling is a classic pull method, while Syslog and MDT are push-based. MDT offers higher scale and flexibility compared to SNMP.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SNMP is a push-based telemetry method where agents send traps to the NMS.
Why it's wrong here
SNMP traps are push, but SNMP polling is pull; the statement is misleading because SNMP is primarily a pull protocol for data collection.
- ✓
Syslog messages can be used as a form of telemetry to report events and state changes.
Why this is correct
Syslog sends event-driven data from devices to a collector, fitting the telemetry definition.
- ✓
Model-driven telemetry supports both periodic and event-driven subscriptions.
Why this is correct
MDT subscriptions can be configured for periodic updates or triggered by changes.
- ✓
gNMI is a protocol used to retrieve and manipulate configuration state, and it also supports telemetry subscriptions.
Why this is correct
gNMI defines RPCs for Get, Set, and Subscribe; the Subscribe RPC is used for telemetry.
- ✗
Telemetry data can only be encoded in XML format.
Why it's wrong here
Telemetry supports multiple encodings including JSON, GPB, and XML.
