- A
curl -X GET -u admin:cisco https://192.168.1.1/restconf/data/ietf-interfaces:interfaces-state/interface=GigabitEthernet0%2F0%2F0
This correctly uses a GET request to the RESTCONF operational state container `interfaces-state` with the interface name URL-encoded.
- B
curl -X GET -u admin:cisco https://192.168.1.1/restconf/data/ietf-interfaces:interfaces/GigabitEthernet0/0/0
Why wrong: This is incorrect because the URL path uses a slash instead of the proper 'interface=' syntax and does not URL-encode the interface name. The correct path uses 'interface=GigabitEthernet0%2F0%2F0'.
- C
curl -X POST -u admin:cisco https://192.168.1.1/restconf/data/ietf-interfaces:interfaces/interface=GigabitEthernet0%2F0%2F0
Why wrong: This is incorrect because it uses the POST method instead of GET. RESTCONF uses GET to retrieve operational state; POST is used to create resources.
- D
curl -X GET -u admin:cisco https://192.168.1.1/restconf/data/Cisco-IOS-XE-interfaces-oper:interfaces/GigabitEthernet0/0/0
Why wrong: This is incorrect because it uses the Cisco-IOS-XE-interfaces-oper YANG module, which is for operational data but the URL path is malformed. The correct path uses the ietf-interfaces module and the 'interface=' syntax with URL encoding.
Quick Answer
The correct answer is the curl command that uses `-X GET` with the path `https://192.168.1.1/restconf/data/ietf-interfaces:interfaces-state/interface=GigabitEthernet0%2F0%2F0`. This is correct because RESTCONF relies on the HTTP GET method to retrieve resource state, and to access operational data—including interface counters like input/output bytes and errors—you must target the `interfaces-state` container within the `ietf-interfaces` YANG module, not the configuration container. The interface name must also be URL-encoded, replacing each forward slash with `%2F`, to form a valid URI. On the CCNA 200-301 v2 exam, this question tests your ability to distinguish between the configuration datastore (`interfaces`) and the operational state datastore (`interfaces-state`), a common trap where candidates mistakenly use POST or omit URL encoding. Remember the memory tip: “State is for stats, config is for commands”—operational state always uses the `-state` suffix and requires GET.
CCNA AI and Network Operations Practice Question
This 200-301 practice question tests your understanding of ai and network operations. 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.
You are connected to R1 via the console. R1 is a Cisco ISR 4321 router running IOS-XE. The network manager wants to monitor interface utilization changes. Use RESTCONF to retrieve the operational state of GigabitEthernet0/0/0 on R1. The device has RESTCONF enabled with username 'admin' and password 'cisco'. The management IP is 192.168.1.1.

Correct answer & explanation
curl -X GET -u admin:cisco https://192.168.1.1/restconf/data/ietf-interfaces:interfaces-state/interface=GigabitEthernet0%2F0%2F0
RESTCONF uses GET to retrieve data. To retrieve operational state (including interface counters), the path must lead to the `interfaces-state` container, not `interfaces`. The correct YANG data model for operational interface state is `ietf-interfaces:interfaces-state`, and the interface name must be URL-encoded to replace slashes with `%2F`. Option C uses POST, which is wrong. Option B lacks URL encoding and uses the config container. Option D uses a Cisco-specific module and unencoded slashes, and is not the standard operational state path.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

- ✓
curl -X GET -u admin:cisco https://192.168.1.1/restconf/data/ietf-interfaces:interfaces-state/interface=GigabitEthernet0%2F0%2F0
Why this is correct
This correctly uses a GET request to the RESTCONF operational state container `interfaces-state` with the interface name URL-encoded.
Related concept
Static NAT maps one inside address to one outside address.
- ✗
curl -X GET -u admin:cisco https://192.168.1.1/restconf/data/ietf-interfaces:interfaces/GigabitEthernet0/0/0
Why it's wrong here
This is incorrect because the URL path uses a slash instead of the proper 'interface=' syntax and does not URL-encode the interface name. The correct path uses 'interface=GigabitEthernet0%2F0%2F0'.
- ✗
curl -X POST -u admin:cisco https://192.168.1.1/restconf/data/ietf-interfaces:interfaces/interface=GigabitEthernet0%2F0%2F0
Why it's wrong here
This is incorrect because it uses the POST method instead of GET. RESTCONF uses GET to retrieve operational state; POST is used to create resources.
- ✗
curl -X GET -u admin:cisco https://192.168.1.1/restconf/data/Cisco-IOS-XE-interfaces-oper:interfaces/GigabitEthernet0/0/0
Why it's wrong here
This is incorrect because it uses the Cisco-IOS-XE-interfaces-oper YANG module, which is for operational data but the URL path is malformed. The correct path uses the ietf-interfaces module and the 'interface=' syntax with URL encoding.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.
✓curl -X GET -u admin:cisco https://192.168.1.1/restconf/data/ietf-interfaces:interfaces-state/interface=GigabitEthernet0%2F0%2F0Correct answer▾
Why this is correct
This correctly uses a GET request to the RESTCONF operational state container `interfaces-state` with the interface name URL-encoded.
✗curl -X GET -u admin:cisco https://192.168.1.1/restconf/data/ietf-interfaces:interfaces/GigabitEthernet0/0/0Wrong answer — click to see why▾
Why this is wrong here
The specific factual error: RESTCONF requires the interface name to be specified as a key in the URL using 'interface=' and the name must be URL-encoded because it contains slashes.
Why candidates choose this
Candidates might think that appending the interface name directly after 'interfaces/' is sufficient, similar to how some other APIs work.
✗curl -X POST -u admin:cisco https://192.168.1.1/restconf/data/ietf-interfaces:interfaces/interface=GigabitEthernet0%2F0%2F0Wrong answer — click to see why▾
Why this is wrong here
The specific factual error: POST is not the correct HTTP method for retrieving data; GET should be used.
Why candidates choose this
Candidates may confuse POST with GET, especially if they are more familiar with other REST APIs where POST is used for queries.
✗curl -X GET -u admin:cisco https://192.168.1.1/restconf/data/Cisco-IOS-XE-interfaces-oper:interfaces/GigabitEthernet0/0/0Wrong answer — click to see why▾
Why this is wrong here
The specific factual error: The URL path does not follow RESTCONF conventions for specifying a list instance; it should use 'interface=GigabitEthernet0%2F0%2F0'.
Why candidates choose this
Candidates might think that using a Cisco-specific YANG module is correct, and they may forget to URL-encode the interface name.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
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.
