Hi,
I don’t get it where I answer wrong in the theory section.
If double checked the answers with the documentation, but I have no clue what might be wrong. In the workflow section I got always 100% percent. In the theory between 62-77%.

My Unique-ID: 522b354d7537ad3fbb9ee861642368fb

Questions and my answers:

What can you do if there is no n8n node for an app/service that you want to use in a workflow?*

Here I assume that here C would be the correct choice:

A Ask the n8n team to create the node - might be an option if I really would like to have the node :wink:

B Create the node yourself - might be an option via community nodes

C Use the HTTP Request node instead - correct

Which of the following are Core Nodes?*

Here I assume that A, C, D would be correct

A Schedule node

B Telegram node

C IF node

D Webhook node

Which of the following are Trigger Nodes?*

Here I assume that A would be correct

A Schedule node

B Code node

C Airtable node

D Edit Fields node

Where do you get credentials for app/service nodes?\

Here I assume that B would be correct

A From the n8n documentation

B From the respective app/service you want to use

C From the dark web

You can download your workflows as .exe files.*

Here I assume that B would be correct

A True

B False

You can import a workflow from a URL or from a local JSON file.*

Here I assume that A and B would be correct

A True

B False

How does the Code node execute code?*

Here I assume that A and B would be correct

A The code gets executed only once for all items.

B The code gets executed once for every item.

What is the difference between the IF node and the Switch node?*

Here I assume that B would be correct

A None, they are the same.

B The IF node supports two conditional routes, the Switch node supports unlimited conditional routes.

C The IF node supports unlimited conditional routes, the Switch node supports two conditional routes.

What programming language can you use in the Code node?*
Here I assume that A and C would be correct

A JavaScript

B TypeScript

C Python

D Any programming language

What is the correct data structure?*

Here I assume that A would be correct

A {[json: {jsonKeyName: ‘keyValue’}]}

B [{json: {jsonKeyName: ‘keyValue’}}]

C json: [jsonKeyName: ‘keyValue’]

When executing the Code node, you might get an error “Error: Code doesn’t return items properly”. What is the reason for this error?*

Here I assume that A would be correct

A The code in the Code node doesn’t return the data in the correct structure.

B The Code node doesn’t receive any incoming data.

C The node needs credentials.

You can only activate workflows that have a Trigger node or a Webhook node.*

Here I assume that A would be correct

A True

B False

What can be the reasons for node errors?*

Here I assume that A and B would be correct

A The node credentials are missing or are incorrect.

B The node parameters are not configured correctly.

C You don’t have permission to use that node.

Welcome to the community @knutlinke

I dont think anything is wrong in those questions.

Hi @knutlinke Please consider not revealing or giving your assumptions of n8n text courses answers, for now just retake the quiz!

Hi,
I’m not sure how “for now, just retake the quiz” is helpful.
Isn’t a forum meant for discussion and exchange?
Could you please point out any mistakes in my answers or suggest what I should review so I can understand and correct them? I’ve tried several times with the same answers and received scores between 62% and 77%.
Thank you Anshul!

Hey @knutlinke , I got you, and you’re right that forums are for discussion.

That said, sharing full quiz answers can be tricky since the course quizzes are meant to assess individual understanding and are tied to badges. That’s probably why people are being cautious.

If there are specific concepts you’re unsure about, feel free to ask about those. The community can definitely help clarify topics without giving away the quiz itself. You can always message n8n experts personally regarding something being off that you have caught like this. That is why i am not making any comment on your answers/assumptions are right or wrong. I hope you are getting my point.

No problem. Lets discuss the ansers. I got again 77% - and I’m sure you checked the my answers and you can see where my missing point is.

What can you do if there is no n8n node for an app/service that you want to use in a workflow?* –> As figured out in the section 1 - we can access other pages via API or “HTTP Request”; As far as I know I can’t gerade a standard node by myself and I should may not contact the N8N.

Which of the following are Core Nodes?* → Should be clear from the documentation: Schedule, IF and Webhook node. Telegram is not a core node IMO.

Which of the following are Trigger Nodes?* –> You can trigger via a schedule node, but not with the others nodes as fas as I understood those concepts.

Where do you get credentials for app/service nodes?\ –> Of course from the other services…

You can download your workflows as .exe files.* –> N8N does not provide a .exe…

You can import a workflow from a URL or from a local JSON file.* –> When I got the functions right I can import from an URL or from a JSON.

How does the Code node execute code?* –> As explained in Lesson 1 both would be correct.

What is the difference between the IF node and the Switch node?* –> Must be clear for every computer scientist and can be only B.

What programming language can you use in the Code node?* –> As far as I can see (and insert) JavaScript and Python.

What is the correct data structure?* –> {Object[Array{Values}]}…

When executing the Code node, you might get an error “Error: Code doesn’t return items properly”. What is the reason for this error?* –> When the error message is correct and specific it should be A.

You can only activate workflows that have a Trigger node or a Webhook node.* –> I found so far no other options to activate a workflow… or does the button “Execute Workflow” counts?

What can be the reasons for node errors?* –> So far I got it, N8N has no user and right management in place. So when node credentials are missing or are incorrect or the node parameters are not configured correctly an error would appear.

Please provide a hint where an error might exist or which documentation would be useful to study. Thank you very much Anshul! :slight_smile:

@knutlinke Sir the best resource is:

And level 1 is pretty much it and some basic common questions you can use this docs to get all the hints i would say. :wink: GoodLuck!
