200-901 Understanding and Using APIs Practice Question

This 200-901 practice question tests your understanding of understanding and using apis. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.

A large enterprise uses Cisco Meraki for their wireless and switching infrastructure. The network team has developed a Python script that uses the Meraki API to automatically update SSID configurations across all networks. The script has been running successfully for months, performing daily updates to SSID settings such as names, passwords, and VLAN assignments. Recently, the script started failing with the following error message: '{"errors":["This operation is not allowed for this network"]}'. The team has verified the following: the API key is still valid and has access to the full organization, the network IDs used in the script are correct and the networks are active, and no changes have been made to the script code. The script uses the PUT endpoint '/networks/{networkId}/wireless/ssids/{number}' to update SSIDs. What is the most likely cause of the failure?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

Question 1hardmultiple choice

Open the full VLAN trunking answer →

A
The Meraki API rate limit has been exceeded, and the request is being rejected.
Why wrong: Rate limit exceeded results in a 429 status code, not a 403 or this specific error message.
B
The network(s) have been moved to a different organization in the Meraki dashboard.
When a network is moved to another organization, the original API key loses access, causing this error.
C
The API key has been downgraded to read-only access due to a security compliance audit.
Why wrong: A read-only key would result in a 403 Forbidden error with a message like 'Insufficient privileges', not 'not allowed for this network' specifically.
D
The SSID number used in the request does not exist on the target network.
Why wrong: A non-existent SSID would cause a 404 Not Found error, not a 403 error.

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

✓

The network(s) have been moved to a different organization in the Meraki dashboard.

Option B is correct. The error 'This operation is not allowed for this network' typically occurs when the API key does not have permission on the network, often because the network has been moved to a different organization. Option A would result in a 429 Too Many Requests error. Option C would produce a 403 Forbidden error with a different message. Option D would yield a 404 Not Found error.

Key principle: A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.

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

✗
The Meraki API rate limit has been exceeded, and the request is being rejected.
Why it's wrong here
Rate limit exceeded results in a 429 status code, not a 403 or this specific error message.
✓
The network(s) have been moved to a different organization in the Meraki dashboard.
Why this is correct
When a network is moved to another organization, the original API key loses access, causing this error.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Access ports place end devices into a single VLAN.
✗
The API key has been downgraded to read-only access due to a security compliance audit.
Why it's wrong here
A read-only key would result in a 403 Forbidden error with a message like 'Insufficient privileges', not 'not allowed for this network' specifically.
✗
The SSID number used in the request does not exist on the target network.
Why it's wrong here
A non-existent SSID would cause a 404 Not Found error, not a 403 error.

Common exam traps

Common exam trap: an active trunk can still block the VLAN you need

A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.

Detailed technical explanation

How to think about this question

VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.

KKey Concepts to Remember

Access ports place end devices into a single VLAN.
Trunk ports carry multiple VLANs between switches.
Allowed VLAN lists decide which VLANs can cross a trunk.
Native VLAN mismatch can create confusing symptoms.

TExam Day Tips

Use show vlan brief to verify access VLANs.
Use show interfaces trunk to verify trunk state and allowed VLANs.
Do not treat every same-VLAN issue as a routing problem.

Key takeaway

A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.

Real-world example

How this comes up in practice

A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.

What to study next

Got this wrong? Here's your next step.

Review VLAN allowed lists, native VLAN mismatch detection, and how to verify VLAN membership with show vlan brief and show interfaces trunk. Then practise related 200-901 questions on switching, trunking, and access-port configuration.
