Quick Answer
The answer is a destination profile with collector IP and port, a sensor path, and a subscription. These three components form the core of model-driven telemetry on Cisco NX-OS because the destination profile defines where to send the data, the sensor path specifies exactly which YANG data model paths to stream—such as interface counters or system inventory—and the subscription binds the sensor path to the destination profile, controlling the update frequency and encoding. On the Cisco DCCOR 350-601 exam, this question tests your ability to distinguish mandatory telemetry building blocks from optional features like data encodings or transport protocols; a common trap is confusing the sensor path with the destination profile or forgetting that a subscription is required to link them. For a quick memory aid, think of the three as the "what, where, and how often"—sensor path (what data), destination profile (where to send it), and subscription (how often to stream it).
This 350-601 practice question tests your understanding of automation. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A data center engineer is implementing model-driven telemetry using Cisco NX-OS. Which three components are required in the telemetry configuration? (Choose three.)
A HTTPS certificate for authentication
Why wrong: Optional, not required for basic telemetry.
An SNMP community string
Why wrong: Not used in telemetry; used for SNMP.
A sensor path to specify the data to stream
Specifies which data to collect.
A subscription to a YANG data model
Subscribes to the data model.
A destination profile with collector IP and port
Defines where to send telemetry.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
A sensor path to specify the data to stream
Option C is correct because a sensor path defines the specific YANG data model paths or operational data that the device will stream to the collector. In model-driven telemetry on Cisco NX-OS, the sensor path is the fundamental component that tells the device exactly which data to monitor and stream, such as 'Cisco-NX-OS-device:System/clock-items' or interface statistics paths.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates confuse model-driven telemetry with SNMP or traditional monitoring, mistakenly thinking SNMP community strings or HTTPS certificates are core components, when in fact the three required components are the sensor path, subscription, and destination profile.
Detailed technical explanation
Model-driven telemetry on NX-OS uses a publish-subscribe model where the device (publisher) streams data based on configured sensor paths to a collector (subscriber). The destination profile includes the collector IP, port, and transport protocol (e.g., gRPC, UDP), while the subscription binds the sensor path to the destination profile, enabling continuous streaming without polling. A common real-world scenario is streaming interface counters every 30 seconds using a periodic subscription, which reduces CPU overhead compared to SNMP polling.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
