Cisco Developing Applications using Cisco Core Platforms and APIs (DEVCOR) Sample Questions:
Question #1
Drag and Drop Question
Drag and drop the code snippets from the bottom onto the blanks in the code to implement an API rate limit and reduce the frequency to less than 1 second. Not all options are used.
Correct Answer:
Explanation:
content-typeis the correct HTTP header key for specifying media type.
429is the HTTP status code for "Too Many Requests" - used when rate limits are exceeded.
Retry-Afteris the header returned by the server indicating how long to wait before retrying.
The function str()is used to convert the integer value of retry_time into a string so it can be concatenated with the surrounding string message. Without this conversion, Python would raise a TypeError, because you can't concatenate a string ('Too many requests, trying again in ') with an integer (retry_time) directly.
Question #2
An engineer is developing a Docker container for an application in Python. For security reasons the application needs to be accessible on port 5001 only. Which line should be added to the dockerfile in order to accomplish this?
- A. PORT SRC 5001
- B. ENTRYPOINT 5001
- C. ADO PORT 5001
- D. EXPOSE 5001
Correct Answer: D 🗳️
Explanation: Only visible for Exam4Tests members. You can sign-up / login (it's free).
Question #3
Drag and Drop Question
Drag and drop the code snippets from the bottom onto the blanks in the script to retrieve consolidated information about blades and rack units through an API request to Cisco Intersight.
The API is used for the automated collection of device statistics from a large deployment of servers in a local data center and imported into Intersight for monitoring purposes. Not all options are used.
Correct Answer:
Explanation:
resource_path→ Defines the API endpoint for retrieving compute device summaries.
request_method→ Specifies the HTTP request method (GET).
operation→ Extracts the API resource path dynamically.
AUTH→ Uses Intersight authentication credentials for secure API access.
Question #4
Drag and Drop Question
A developer is creating a Python script to catch errors using REST API calls and to aid in debugging. Drag and drop the code from the bottom onto the box where the code is missing to implement control flow for REST API errors. Not all options are used.
Correct Answer:
Explanation:
In the event of a network problem (e.g. DNS failure, refused connection, etc), Requests will raise a ConnectionError exception.
In the event of the rare invalid HTTP response, Requests will raise an HTTPError exception.
If a request times out, a Timeout exception is raised.
If a request exceeds the configured number of maximum redirections, a TooManyRedirects exception is raised.
All exceptions that Requests explicitly raises inherit from requests.exceptions.RequestException.
https://docs.python-requests.org/en/latest/user/quickstart/#errors-and-exceptions
Question #5
Refer to the exhibit. The deployment team prepared the docker config considering service uptime security, and access from other services. They want to ensure that the configuration allows integration with an external network. Based on the Docker Compose configuration what should the team expect regarding the network setup?
- A. DB is configured with two networks simultaneously
- B. cache uses db_data volume
- C. API is configured with two networks simultaneously
- D. publicnet links cache and db together.
Correct Answer: C 🗳️
