CCNA AI and Network Operations Practice Question
Which term describes a string or credential passed to an API to prove the client is allowed to access a resource?
⚠ Common exam trap
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.
Answer choices
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
✓
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.
Answer analysis
Option-by-option breakdown
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 numeric cost or distance value used by routing protocols like OSPF or EIGRP to compare paths to a destination. It influences route selection by quantifying factors such as bandwidth, delay, or hop count, and has no role as an API authorization credential.
When this WOULD be correct
In a question about monitoring or performance, such as 'Which term describes a value used to measure the performance of an API endpoint?', metric would be the correct answer.
- ✓
Token
Why this is correct
A token is a compact credential string, such as an OAuth 2.0 bearer token or a JWT, that the client presents to an API, typically in the Authorization header. It grants authenticated access and may carry scopes or expiry, making it the correct term for a credential passed to an API.
- ✗
Lease
Why it's wrong here
In networking, a lease is specifically assigned by DHCP to define the duration an IP address remains valid for a client, after which it must be renewed. It controls address allocation, not API authentication, and does not function as a request credential.
When this WOULD be correct
In a question about DHCP operation, 'lease' would be correct when asking: 'What term describes the temporary assignment of an IP address to a client by a DHCP server?'
- ✗
Tuple
Why it's wrong here
A tuple is an ordered finite list of elements, commonly used in mathematics, relational databases, and programming languages to represent a row or a fixed collection of values. It is a structural data concept rather than a security credential, so it cannot be passed to an API for verification.
When this WOULD be correct
In a question about data structures or database queries, such as 'Which term describes an ordered list of elements in Python or a row in a relational database?', tuple would be the correct answer.
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.
✓TokenCorrect answer▾
Why this is correct
A token is a compact credential string, such as an OAuth 2.0 bearer token or a JWT, that the client presents to an API, typically in the Authorization header. It grants authenticated access and may carry scopes or expiry, making it the correct term for a credential passed to an API.
✗MetricWrong answer — click to see why▾
Why this is wrong here
A metric is a quantitative measurement, not a credential for API access. The question specifically asks for a string or credential used to prove authorization, which is a token.
★ When this WOULD be the correct answer
In a question about monitoring or performance, such as 'Which term describes a value used to measure the performance of an API endpoint?', metric would be the correct answer.
Why candidates choose this
Candidates may confuse 'metric' with 'token' because both are strings used in API contexts, but metrics are for measurement, not authentication.
✗LeaseWrong answer — click to see why▾
Why this is wrong here
A lease in IT typically refers to a time-limited grant of access or resource usage (e.g., DHCP lease, IP address lease), not a credential passed to an API for authentication or authorization.
★ When this WOULD be the correct answer
In a question about DHCP operation, 'lease' would be correct when asking: 'What term describes the temporary assignment of an IP address to a client by a DHCP server?'
Why candidates choose this
Candidates may confuse 'lease' with 'token' because both involve temporary access, but a lease is about resource allocation duration, not API authentication credentials.
✗TupleWrong answer — click to see why▾
Why this is wrong here
A tuple is an ordered list of elements, typically used in database contexts or to represent a set of values, not as a credential for API access.
★ When this WOULD be the correct answer
In a question about data structures or database queries, such as 'Which term describes an ordered list of elements in Python or a row in a relational database?', tuple would be the correct answer.
Why candidates choose this
Candidates may confuse 'tuple' with 'token' due to similar spelling or think it refers to a security credential like a 'token' in some contexts.

Quick reference
Routing Protocol Comparison
| Protocol | Metric | Max Hops | Algorithm | Type |
|---|---|---|---|---|
| RIP v2 | Hop count | 15 | Bellman-Ford | Distance vector |
| OSPF | Cost (bandwidth) | Unlimited | Dijkstra (SPF) | Link state |
| EIGRP | Composite metric | Unlimited | DUAL | Hybrid |
| IS-IS | Cost | Unlimited | Dijkstra | Link state |
| BGP | Policy / attributes | Unlimited | Path vector | Path vector |
RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.
