CV0-003 Exam - Question 29


A developer is no longer able to access a public cloud API deployment, which was working ten minutes prior. Which of the following is MOST likely the cause?

Show Answer
Correct Answer: BD

The most likely cause of a sudden inability to access a public cloud API deployment, which was accessible just ten minutes prior, is an invalid API token. API tokens are used to authenticate API requests and typically have a limited duration of validity. If the token expires or is revoked, the developer will no longer be able to access the API. This sudden loss of access is more consistent with an authentication issue such as an invalid API token, whereas issues like rate limiting, network bandwidth, or invalid API requests are less likely to cause an abrupt complete loss of access.

The correct answer is “B.” An API token is necessary before the API request can be sent. If the token is no longer working, the API request wouldn’t be submitted.

Why not A?

I was originally thinking A because it said Public, thinking it was referring to a PUblic API. Which I dismissed the API token because public API didn’t use authentication. I re-read the question. It is a API provided from a cloud provider. Public cloud providers are AWS,Azure, etc. you would need to authenticate into the public cloud to use the API. Hope you understand the logic.

The MOST likely cause, given the information provided, is: B. Invalid API token. If a developer was able to access a public cloud API and suddenly loses access, one common reason for this is an invalid API token. API tokens often have a limited duration of validity, and if the token expires or becomes invalid for some reason, the developer won't be able to access the API anymore. While the other options (rate limiting, depleted network bandwidth, and invalid API requests) are also potential causes of API access issues, the sudden loss of access in this scenario is more likely related to an authentication issue, such as an expired or invalid API token.

Rate limiting is a strategy for limiting network traffic. It puts a cap on how often someone can repeat an action within a certain timeframe – for instance, trying to log in to an account. Rate limiting can help stop certain kinds of malicious bot activity. It can also reduce strain on web servers. Rate limiting protects an API by applying a hard limit on its access.

It's B, token is refreshed

I'm going to go with A: API limit The question ask about a PUBLIC API, which I don't think a session token would be used to authenticate with.....

Answer is B API token.

B. Invalid API token. An API token is typically used to authenticate the client making API requests to the cloud API. If the token becomes invalid, either because it has expired or because it has been revoked, the client will no longer be able to access the API. This can result in the developer being unable to access the API deployment, even if it was working previously. API provider rate limiting, depleted network bandwidth, and invalid API request can also cause issues with accessing an API deployment, but are less likely to be the cause if the API was working previously and suddenly stopped. These issues are more likely to result in a slow or inconsistent response from the API, rather than a complete inability to access it.

B all the way

I would say rate limit. For example, with twitter you can get 50 tweets within a 15 minute time period, additional requests will be denied until the 15 minutes pass.

Who's going out here assigning ChatGPT answers to these questions lol. Cannot access "the api", so the entire api. It assumes too much to say "only one request they made was wrong".

B. Invalid API token: API tokens can expire or become invalid due to several reasons (e.g., token expiration, token revocation for security reasons, or misconfiguration). If the token expired or was revoked, the developer would lose access suddenly, which fits the scenario described.
