Question 1

An engineer enables model-driven telemetry (MDT) on an NX-OS device to stream interface statistics via gRPC to a collector every 10 seconds. Which telemetry subscription component defines exactly which YANG path(s) are streamed and at what cadence?

A. The `event manager applet` configuration

B. A `sensor-group` (defining the YANG paths) bound to a `subscription` that references a
`destination-group` and specifies the sample interval

C. The `telemetry` feature flag alone, with no further configuration needed

D. SNMP MIB OID definitions configured under `snmp-server`

Question 2

Drag and Drop Question

Question 3

In a Nexus Dashboard Fabric Controller (NDFC) managed VXLAN EVPN fabric, an engineer wants to onboard a new leaf switch using Zero Touch Provisioning combined with a pre-defined role and interface configuration policy. Which NDFC concept enables this automated bootstrap- and-configuration workflow?

A. NX-API `cli_conf` calls triggered only after manual IP assignment

B. Manual `copy running-config startup-config` after console login

C. SNMP `set` requests issued from NDFC at first boot

D. POAP (PowerOn Auto Provisioning) integrated with NDFC's fabric templates and switch role assignment

Question 4

While reviewing an APIC REST API response for a failed POST request, an engineer sees an HTTP 400 response with a JSON body containing `"totalCount":"1"` and an `imdata` array with an object of class `error`, whose `text` attribute reads something about an invalid property value.
What does this response structure indicate about how APIC reports errors?

A. The `totalCount` field only applies to successful GET requests, and its presence here is a bug

B. A 400 status code always means the APIC controller is unreachable

C. APIC never returns structured error information; only raw HTTP status codes are meaningful

D. APIC embeds error details as a managed object of class `error` within the standard `imdata` response envelope, meaning error handling code must parse the response body (not just the HTTP status code) to extract a human-readable reason

Question 6

Drag and Drop Question
When a switch boots it does not find its startup-config file. Drag and drop the steps that Power-On Auto Provisioning goes through to configure the switch for remote management from the left into the correct order on the right. Not all options are used.

Question 7

Regarding "AI in Automation" capabilities being introduced into data-center automation (e.g., AI- assisted configuration generation, anomaly detection, root-cause analysis), which statement most accurately describes their typical positioning in current Cisco data-center automation products (e.g., AI-related features in Nexus Dashboard)?

A. They function as decision-support/augmentation tools - leveraging historical telemetry and ML models to assist anomaly detection, root-cause localization, and configuration suggestions, while actual changes still require human approval or an established approval workflow

B. They are limited to generating static documentation and involve no real-time data analysis

C. They fully replace human engineers in making configuration change decisions

D. AI capabilities are limited to chatbot-style CLI translation and do not involve network telemetry analysis

Question 8

An engineer uses Python's `ncclient` library to push configuration to a Nexus 9000 over NETCONF. The script raises an `RPCError`, but device logs show the configuration was actually applied. Which of the following is the most likely root cause?

A. `edit-config` targeted `running` instead of `candidate`, and `commit` was never issued

B. The NETCONF session did not advertise the `:candidate` capability, so the target datastore has no candidate/commit model; the device applied the change directly to running, but returned an incompatible response to the subsequent `commit` RPC, which the client interpreted as an error

C. The ncclient version is incompatible with the NX-OS YANG models

D. The configuration payload used an undefined namespace prefix
