This 200-301 practice question tests your understanding of ai and network operations. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. A key principle to apply: an API token is a credential string passed to prove client authorization when accessing network resources programmatically.. 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.
Which term describes a string or credential passed to an API to prove the client is allowed to access a resource?
Metric
Why wrong: A metric is a route cost value in networking.
Token
That is the authorization credential described.
Lease
Why wrong: A lease is normally tied to DHCP.
Tuple
Why wrong: A tuple is a data structure term, not the authorization credential here.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Token
A token is commonly used for API authorization. It is often included in an HTTP header and lets the server verify the caller has permission.
Key principle: An API token is a credential string passed to prove client authorization when accessing network resources programmatically.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Metric
Why it's wrong here
A metric is a route cost value in networking.
Token
Why this is correct
That is the authorization credential described.

Common exam traps
A common exam trap is mistaking the term 'token' for other networking terms such as 'metric,' 'lease,' or 'tuple.' Candidates might confuse 'metric' as a general value related to network performance or 'lease' as a temporary credential, but these terms do not relate to API authorization. Another trap is assuming that any credential passed to an API is called a 'lease' or 'tuple,' which are unrelated concepts. Recognizing that a token specifically serves as an authorization credential passed to prove client access rights is critical to avoid this confusion.
Detailed technical explanation
An API token is a string or credential used to authenticate and authorize a client application when accessing a network device or service programmatically. In Cisco automation and programmability contexts, tokens are passed in API requests, often in HTTP headers, to prove the client has permission to perform actions or retrieve data. This mechanism ensures secure communication between the client and the network device, preventing unauthorized access. The decision to use a token for API access is based on security best practices. Tokens are preferred over static credentials because they can be time-limited, scoped to specific permissions, and revoked if compromised. Cisco devices supporting RESTCONF or NETCONF APIs typically require tokens or similar credentials to validate client requests, ensuring that only authorized automation scripts or applications can modify configurations or query operational data. A common exam trap is confusing tokens with other networking terms like metric, lease, or tuple, which have distinct meanings unrelated to API authorization. Understanding that a token specifically serves as an authorization credential in API contexts helps avoid this confusion. Practically, network engineers use tokens to automate tasks securely, enabling scalable and controlled network management without exposing sensitive passwords directly in scripts.
Key takeaway
An API token is a credential string passed to prove client authorization when accessing network resources programmatically.
Real-world example
A junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
