Quick Answer

The correct answer pairs NETCONF with the description “Protocol using XML over SSH for configuration management and transactional operations” because NETCONF is specifically designed as a network configuration protocol that uses XML-encoded data and relies on SSH for secure transport, supporting transactional rollback and atomic operations. YANG, by contrast, is the data modeling language that defines the structure of the data NETCONF and RESTCONF manipulate, while RESTCONF is a RESTful API over HTTPS using standard HTTP methods. On the CCNA 200-301 v2 exam, this drag-and-drop task tests your ability to distinguish between the protocol (NETCONF), the data model (YANG), and the RESTful interface (RESTCONF)—a common trap is confusing YANG as a protocol rather than a modeling language. Remember the memory tip: “YANG models the data, NETCONF moves it over SSH, RESTCONF uses HTTP verbs.”

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.

YANG: Data modeling language used to define configuration and state data structures

YANG is a data modeling language used to define configuration and state data. NETCONF is an XML-based protocol over SSH that supports transactional configuration management. RESTCONF is a RESTful API over HTTPS that uses standard HTTP methods like GET, PUT, POST, DELETE. NETCONF <edit-config> is an operation that modifies configuration with options like merge, replace, create, delete. RESTCONF PATCH is an HTTP method used for partial updates to a resource.

Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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.

What to study next

Got this wrong? Here's your next step.

Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 200-301 NAT questions on configuration and troubleshooting.
