Demo Questions

Question 1
An authentication script fails to connect to an internal server exactly 1 out of 2 times it is executed. This behavior is seen from different clients. Which networking device must be at fault?

  • A: Laptop on which the scripted is running
  • B: Router
  • C: Switch
  • D: Load balancer
Correct Answer: D
D is the only logical choice. Scenario would be that it is load balancing 2 servers, but one is having an issue.  
That could cause *exactly* 1 out of 2 times a failure.



Question 2
Which two items are Cisco DevNet resources? (Choose two.)

  • A: TAC support
  • B: Bitbucket
  • C: Sandbox
  • D: Software research
  • E: API Documentation
Correct Answer: CE
https://developer.cisco.com/



Question 3
In python, which expression checks whether the script returns a success status code when the Requests library is used?

  • A: response.status_code == requests.ok
  • B: response.status_code == requests.codes.ok
  • C: response.code == requests.codes.ok
  • D: response.status_code ! == requests.codes.ok
Correct Answer: B
response.status_code == requests.code.ok  
response + status_code from library equals requests imported . code from requets library and response code ok



Question 4
What is the outcome of executing this command?  
  
git clone ssh:/[email protected]/path/to/my-project.git

  • A: Creates a local copy of a repository called "my-project"
  • B: Creates a copy of a branch called "my-project"
  • C: Initiates a new Git repository called "my-project"
  • D: Creates a new branch called "my-project"
Correct Answer: A
git clone is primarily used to point to an existing repo and make a clone or copy of that repo at in a new directory, at another location. The original repository can be located on the local filesystem or on remote machine accessible supported protocols. The git clone command copies an existing Git repository.



Question 5
Refer to the exhibit. What does the python function do?  
  
    

  • A: It returns DNAC user and password.
  • B: It returns HTTP Basic Authentication.
  • C: It returns an authorization token.
  • D: It reads a token from a local JSON file and posts the token to the DNAC URL.
Correct Answer: C
You need to retrieve information through the API, so we need to do a GET request; don’t forget the X-Auth-Token header containing the authorization token.

  • C: Multicast NAT
  • D: Dynamic NAT
  • E: Router NAT

Question 7
Which two statements are true about Cisco UCS Manager, Cisco UCS Director, or Cisco Intersight APIs? (Choose two.)

  • A: Cisco Intersight API interactions can be encoded in XML or JSON and require an APIs key in the HTTP header for authentication.
  • B: USC Director API interactions can be XML-or JSON-encoded and require an APLs key in the HTTP header for authentication.
  • C: UCS manager API interactions are XML-encoded and require a cookie in the method for authentication.
  • D: Cisco Intersight uses XML to encoded API interactions and requires an API key pair for authentication.
  • E: UCS manager uses JSON to encode API interactions and utilizes Base64-encoded credentials in the HTTP header for authentication.  
Correct Answer: BC
UCS Manager - XML only - Authentication by Cookie  
UCS Director - JSON or XML - Authentication by TokenID  
Intersight - JSON only - Authentication by TokenID (keyID and secretkey) and Session Cookies



Question 8
A developer is writing an application that uses a REST API and the application requires a valid response from the API.  
Which element of the response is used in the conditional check?

  • A: URL

Which task is performed because the test-driven development approach is being used?

  • A: testing existing software before developing new code
  • B: refactoring code that is covered by existing tests
  • C: writing code without committing any coding violations
  • D: creating test scenarios based on continuous development
Correct Answer: B
TDD States: 
1. Write tests.  
2. Run these tests; they must fail (code may not even compile).  
3. Write source code.  
4. Run all tests; they must pass.  
5. Refactor the code where necessary.
