200-901 Practice Question: The exhibit shows a JSON response from a Cisco…

Exhibit

Refer to the exhibit.
{
  "result": {
    "interfaces": [
      {
        "if-name": "Ethernet1/1",
        "admin-state": "up",
        "oper-state": "down"
      }
    ]
  }
}

The exhibit shows a JSON response from a Cisco NX-OS API query for interface status. What is the operational state of interface Ethernet1/1?

⚠ Common exam trap

Cisco often tests the distinction between administrative state (adminState) and operational state (operState), where candidates mistakenly assume that an interface with adminState 'up' must also be operationally 'up', but the operational state depends on physical and protocol conditions.

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

✓

down

The JSON response shows the interface Ethernet1/1 with an 'operState' value of 'down'. In Cisco NX-OS, the 'operState' field directly reflects the operational status of the interface, which is determined by Layer 1 and Layer 2 conditions such as cable connectivity, signal detection, and protocol state. Since the value is 'down', the interface is not passing traffic, making option B correct.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    unknown

    Why it's wrong here

    The JSON exhibit reports the interface's operational state as up, with admin state enabled; 'unknown' is not present in the response. Unknown would be the correct reading only if the API returned no state field or an unrecognised value, indicating the device had not reported status.

  • ✓

    down

    Why this is correct

    The JSON response reports Ethernet1/1 with admin state enabled but oper state down, meaning the interface is administratively up yet has no link. This satisfies the stem's request for operational state, which reflects link-level status rather than configured intent.

  • ✗

    admin-down

    Why it's wrong here

    Admin-down describes the administrative state, not the operational state requested. The exhibit shows the interface administratively enabled and operationally up. Admin-down would be the answer if the query asked for the configured admin status and the interface had been shut down.

  • ✗

    up

    Why it's wrong here

    The exhibit's JSON shows the interface operational state as down, not up, so this misreads the returned field. Up would be correct if the state value in the response were 'up'; here the device reports the link as not operational despite being administratively enabled.
