200-901 Practice Question: Refer to the exhibit

Exhibit

Refer to the exhibit.

{
  "Cisco-IOS-XE-native:interface": {
    "GigabitEthernet": [
      {
        "name": "1/0/1",
        "description": "Server port",
        "ip": {
          "address": {
            "primary": {
              "address": "192.168.1.1",
              "mask": "255.255.255.0"
            }
          }
        },
        "switchport": {
          "access": {
            "vlan": 10
          },
          "mode": "access"
        }
      }
    ]
  }
}

Refer to the exhibit. A Python script using RESTCONF sends a GET request to retrieve the interface configuration. The response is shown. What is the VLAN assigned to GigabitEthernet1/0/1?

⚠ Common exam trap

Cisco often tests whether candidates can distinguish between the 'native-vlan' field (which represents the access VLAN for an access port) and the default VLAN 1, leading many to incorrectly select VLAN 1 when the response clearly shows a different value.

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

10

(VLAN 10) because the RESTCONF GET response shows the native VLAN for GigabitEthernet1/0/1 is set to 10. In Cisco IOS-XE, the native VLAN is the VLAN assigned to an interface when it is in access mode, and the response explicitly includes the 'native-vlan' field with a value of 10 under the 'Cisco-IOS-XE-native:interface' hierarchy.

Answer analysis

Option-by-option breakdown

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

  • 10

    Why this is correct

    The JSON clearly shows 'vlan': 10.

  • 1

    Why it's wrong here

    The exhibit shows vlan 10.

  • 100

    Why it's wrong here

    Not in the exhibit.

  • 20

    Why it's wrong here

    Not in the exhibit.

Visual reference

Switch VLAN 10 Sales (192.168.10.0/24) PC-A PC-B VLAN 20 HR (192.168.20.0/24) PC-C PC-D Router VLANs isolate traffic — inter-VLAN routing requires a Layer 3 device
