CCNA AI and Network Operations Practice Question
Which two statements accurately describe JSON?
⚠ Common exam trap
A frequent exam trap is confusing JSON with network protocols or features, such as HTTPS or spanning-tree modes. Candidates might incorrectly assume JSON is a transport protocol or a network technology because it is often mentioned alongside APIs and automation. This misunderstanding leads to selecting incorrect answers that describe JSON as a protocol or network mode. The key is to remember that JSON is strictly a data format used to represent structured information, not a protocol or network operation. Misreading JSON’s role can cause errors in questions testing automation and programmability concepts.

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
✓
JSON is a structured data format commonly used by APIs.
JSON is a lightweight structured data format commonly used in APIs and automation workflows. In plain language, it provides a readable way to represent data as key-value pairs, objects, and arrays so software can exchange information consistently. It is popular in network automation because it is compact and widely supported by tools, controllers, and web-based interfaces. CCNA questions on JSON usually test recognition, not coding expertise. You should be able to identify that JSON is a data format, not a transport protocol, and that arrays are shown with square brackets. The correct answers in this question focus on those recognition skills rather than on advanced programming details.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
JSON is a structured data format commonly used by APIs.
Why this is correct
JSON (JavaScript Object Notation) is a lightweight, text-based data-interchange format that represents data as key-value pairs and ordered lists. RESTful APIs frequently use JSON for request and response payloads because it is language-agnostic, human-readable, and easily parsed by most programming languages. Its structure enables nested objects and arrays, making it suitable for complex hierarchical data exchange.
- ✓
JSON uses square brackets for arrays.
Why this is correct
In JSON syntax, arrays are ordered collections of values enclosed in square brackets [ ], with each value separated by a comma. For example, "interfaces": ["GigabitEthernet0/0", "GigabitEthernet0/1"] demonstrates an array of interface names. This distinguishes arrays from objects, which use curly braces { } for key-value pairs.
- ✗
JSON is the same thing as HTTPS.
Why it's wrong here
JSON is a data-interchange format used to structure content, whereas HTTPS (Hypertext Transfer Protocol Secure) is a communication protocol that encrypts and transmits data between clients and servers. They operate at different layers: JSON defines the representation of data, while HTTPS governs the secure transport of that data over TCP port 443. Confusing them conflates a payload format with the transport mechanism that carries it.
When this WOULD be correct
If the exam question asked about the relationship between data formats and protocols, or if it specifically inquired whether JSON can be used in secure communications, then stating that JSON is the same as HTTPS could be interpreted as correct in a misleading context.
- ✗
JSON is required only for IPv6 networks.
Why it's wrong here
JSON is entirely independent of IP addressing or network protocol versions; it functions equally over IPv4, IPv6, or even non-IP transports. IPv6 networks may use JSON for configuration or telemetry, but there is no requirement or dependency between JSON and IPv6. The statement is false because JSON is a data format, not a protocol tied to any particular network layer addressing scheme.
When this WOULD be correct
If the question were about data formats required for specific network configurations, and it specified that JSON is necessary for data representation in IPv6 applications, then this option could be correct. For example, a question could ask which data format is used in APIs for IPv6-enabled services.
- ✗
JSON is a spanning-tree mode.
Why it's wrong here
JSON has no relationship with spanning-tree or Layer 2 redundancy protocols; spanning-tree uses specific port states and bridge roles, not data serialization formats. While network devices may use JSON for configuration or operational output, JSON is not a networking protocol or an IEEE 802.1D feature. Therefore, classifying JSON as a spanning-tree mode is categorically incorrect.
When this WOULD be correct
If the exam question asked about network protocols and their configurations, specifically regarding spanning-tree protocols, then stating that JSON is a spanning-tree mode could be correct if it were rephrased to refer to a specific JSON configuration for spanning-tree settings in a network management context.
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.

✗JSON is the same thing as HTTPS.Wrong answer — click to see why▾
Why this is wrong here
JSON is a data format for representing structured information, while HTTPS (Hypertext Transfer Protocol Secure) is a secure communication protocol used for transmitting data over a network. They operate at different layers of the OSI model and serve entirely different purposes; confusing them is a fundamental category error.
★ When this WOULD be the correct answer
If the exam question asked about the relationship between data formats and protocols, or if it specifically inquired whether JSON can be used in secure communications, then stating that JSON is the same as HTTPS could be interpreted as correct in a misleading context.
Why candidates choose this
Students might confuse JSON with HTTPS because both are commonly associated with web APIs and data exchange. The acronyms sound similar, and both are frequently mentioned together in the context of web services, leading to the mistaken belief that they are the same thing.
✗JSON is required only for IPv6 networks.Wrong answer — click to see why▾
Why this is wrong here
JSON is a data format that is independent of any specific network protocol or addressing scheme. It can be used over IPv4, IPv6, or any other transport layer. There is no requirement or dependency between JSON and IPv6; JSON works equally well on any IP version.
★ When this WOULD be the correct answer
If the question were about data formats required for specific network configurations, and it specified that JSON is necessary for data representation in IPv6 applications, then this option could be correct. For example, a question could ask which data format is used in APIs for IPv6-enabled services.
Why candidates choose this
A test-taker might think JSON is required for IPv6 because both are modern technologies often discussed in the context of network evolution. The word 'required' might trigger a false association, especially if the student has heard that IPv6 networks need new data formats, which is incorrect.
✗JSON is a spanning-tree mode.Wrong answer — click to see why▾
Why this is wrong here
JSON is a data interchange format, whereas spanning-tree is a Layer 2 network protocol used to prevent loops in Ethernet networks. They are completely unrelated; JSON has no role in spanning-tree operation or configuration. Spanning-tree modes include PVST+, Rapid PVST+, and MST.
★ When this WOULD be the correct answer
If the exam question asked about network protocols and their configurations, specifically regarding spanning-tree protocols, then stating that JSON is a spanning-tree mode could be correct if it were rephrased to refer to a specific JSON configuration for spanning-tree settings in a network management context.
Why candidates choose this
The acronym 'JSON' might be confused with 'JST' or other spanning-tree related terms. Additionally, students who are not familiar with JSON might guess that it is a network protocol because it sounds technical, and spanning-tree is a common topic in CCNA, leading to a plausible but incorrect association.
