200-901 Understanding and Using APIs Practice Question

This 200-901 practice question tests your understanding of understanding and using apis. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.

When using the Meraki Dashboard API, what is the correct method to authenticate requests?

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

Include an API key in the X-Cisco-Meraki-API-Key header

The Meraki Dashboard API uses a unique API key for authentication, which must be included in the `X-Cisco-Meraki-API-Key` header. This key is generated per user in the Meraki Dashboard and identifies the request without requiring a session or password. Option D correctly specifies this custom header, which is the only supported method for authenticating requests to the Meraki API.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Include an API key in the Authorization header as a Bearer token

    Why it's wrong here

    Meraki does not use Bearer tokens.

  • Use a session token obtained from a login endpoint

    Why it's wrong here

    Meraki does not use session tokens.

  • Use Basic authentication with username and password

    Why it's wrong here

    Basic auth is not used by Meraki.

  • Include an API key in the X-Cisco-Meraki-API-Key header

    Why this is correct

    This is the correct Meraki authentication method.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Cisco often tests the misconception that all REST APIs use standard Bearer tokens or OAuth, but the Meraki API deliberately uses a custom header to emphasize vendor-specific authentication patterns that candidates must memorize.

Detailed technical explanation

How to think about this question

The Meraki API key is a 40-character hexadecimal string tied to a specific Dashboard administrator account. It must be included in every request as a header, and the API enforces rate limiting (e.g., 5 requests per second per key) to prevent abuse. Under the hood, the key is hashed and validated against the organization's permissions, ensuring that requests are scoped to the user's access level without requiring OAuth or session management.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

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.
