The correct answer is that JSON uses square brackets for arrays. This is because JSON, or JavaScript Object Notation, is a lightweight structured data format that organizes information into key-value pairs within objects, while arrays—ordered lists of values—are always enclosed in square brackets, making them easy to identify. On the CCNA 200-301 v2 exam, questions on JSON test your recognition of its syntax and purpose, not your ability to write code; you must know that JSON is a data format, not a transport protocol like HTTP or SSH. A common trap is confusing JSON objects, which use curly braces, with arrays, so remember that arrays are the square-bracketed lists. For a quick memory tip, think of the brackets as “square pegs for square holes”—arrays fit inside square brackets, objects fit inside curly braces.

✗
JSON is the same thing as HTTPS.
Why it's wrong here
This is wrong because JSON is a data format, while HTTPS is a secure transport protocol.
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
This is wrong because JSON is not tied to IPv6-only environments.
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
This is wrong because JSON is unrelated to spanning-tree operation.
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 a structured data format commonly used by APIs.Correct answer▾
Why this is correct
This is correct because JSON is widely used to represent structured information in API payloads.
✗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.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format that is easy for humans to read and write and easy for machines to parse and generate. It represents data as key-value pairs within objects, and collections of values within arrays, making it ideal for structured data exchange. In networking and automation, JSON is commonly used to format configuration data, API responses, and telemetry information, enabling consistent communication between network devices and management systems.
The core rule for recognizing JSON in the CCNA context is understanding its syntax and role: JSON uses curly braces {} to define objects and square brackets [] to define arrays. This distinction is critical because arrays represent ordered lists of values, which are fundamental in representing multiple data elements such as interface lists or routing entries. Cisco network automation tools and APIs frequently use JSON to exchange structured data, so recognizing JSON’s format helps in interpreting automation workflows and API payloads.
A common exam trap is confusing JSON with transport protocols or network-specific features. For example, JSON is often mistakenly thought to be a protocol like HTTPS or a network technology such as spanning-tree mode. In reality, JSON is purely a data format and does not handle transport or network control functions. Understanding this distinction prevents misinterpretation of JSON’s role in network automation and API communication, ensuring accurate answers on the CCNA exam and practical network automation tasks.
KKey Concepts to Remember
JSON represents structured data using key-value pairs within objects and ordered lists within arrays, enabling consistent data exchange in network automation.
JSON uses curly braces {} to define objects and square brackets [] to define arrays, which is essential for interpreting API payloads and automation data.
Network automation tools and Cisco APIs commonly use JSON to format configuration data and telemetry information for easy parsing and integration.
