Refer to the exhibit. A Python API server has been deployed. Based on metrics and logs, increased load has been noticed. Which two approaches must be taken to optimize API usage on the server? (Choose two.)
Answer: CD
question is similar to question 277. I believe answers should be: Include the “Last-Modified” header in the API response. Include the “ETag” header in the API response.

DRAG DROP - Drag and drop the steps from the left into the order on the right to provide a custom dashboard to display the version of code that is installed in a network subnet using the Cisco DNA Center API.
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
1. Create a POST REST API call to the Authentication API to obtain an access token for Cisco DNA Center. 2. Call the Device List API to retrieve the records associated with the branch offices. 3. Create a query string using the required subnet. 4. Format the data as per the dashboard's requirements. 5. Display all the returned data to the dashboard.

DRAG DROP - Drag and drop the code snippets from the bottom onto the blanks in the code for a Python application that needs to connect to Cisco DNA Center and then query the application for the inventory of devices on the network. The application must be resilient and ensure that it has the proper timeouts defined in the code. If a connection cannot be established to Cisco DNA Center within 5 seconds, the application should be terminated. Not all options are used.

Agree with SzClar, it's 1. requests 2. get 3. Timeout Otherwise, what's the point of importing the Timeout module at the start?

Refer to the exhibit. A developer is creating an application to be used in the current network. The application must be compatible with the network devices and platforms. Based on the design and performance, it must be flexible to modifications and future installations. What are two characteristics of the Python application? (Choose two.)
Answer: AD
AD A. The application design maximizes scalability. The presence of multiple API versions (from v1_2_0 to v2_1_2) in the project structure suggests that the application is designed to handle different versions of APIs, which is a characteristic of scalable systems. D. The application design enables code reuse. The modular structure of the project with separate directories and files for different functionalities (like api, models, validators, etc.) indicates that the application is designed to promote code reuse. Other answers are wrong! Nothing in the exhibit says something about python2 or the content of the files/codes

I think I agree with jxu: client scoreList scoreDetail WIRELESS Although this question is ridiculously formatted to the point that I can't understand it, I hate to say it but this exam is definitely still active in the exam. I've seen it, and it looked exactly the same as this.

DRAG DROP - Drag and drop the code snippets from the bottom onto the blanks in the code to add a new URL object for www.cisco.example.com to the Cisco Firepower Device Management system in an existing collection. The company requires that the additions must be created using the API because this will help the company build local repositories that can be used for other systems as they are installed and configured. The data needs to be transferred in a structured data format. Not all options are used.

What are two principles according to the build, release, run principle of the twelve-factor app methodology? (Choose two.)
Answer: BC
B&C https://12factor.net/ I. Codebase One codebase tracked in revision control, many deploys II. Dependencies Explicitly declare and isolate dependencies III. Config Store config in the environment IV. Backing services Treat backing services as attached resources V. Build, release, run Strictly separate build and run stages VI. Processes Execute the app as one or more stateless processes VII. Port binding Export services via port binding VIII. Concurrency Scale out via the process model IX. Disposability Maximize robustness with fast startup and graceful shutdown X. Dev/prod parity Keep development, staging, and production as similar as possible XI. Logs Treat logs as event streams XII. Admin processes Run admin/management tasks as one-off processes

DRAG DROP - An engineer is trying to modify information on the devcorexample.com repository that is relevant to network resources and capabilities but receives this error: HTTP/1.1 405 Method Not Allowed Allow: PATCH - Drag and drop the code snippets from the bottom onto the blanks in the code to collect the information. Not all options are used.
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
The error message indicates the PATCH method was only one to be accepted. Therefore, the answer should be: 1. curl -X 2. PATCH 3. resources

Refer to the exhibit. An application was developed to be deployed on a global scale. The application will be available to all users of an enterprise and will require secure access. During code review, poor secret storage practices were identified. How must the secret storage approach be changed to improve security?
Answer: A
Cisco's recommendations around storing app secrets: - There is no single correct way to protect secrets, because no approach is optimal for ALL SITUATIONS. - Where possible, use single sign-on systems - Where possible, use multifactor authentication However, none of those apply in these choices :( I think out of the choices given, both A and B are the best options. I'm leaning towards A, because B doesn't specify how the environment variable is stored, and whether such storage is secure. For example, storing on disk or in your git repo in a .env file is not secure. Typing it in by hand like: export DB_PWD="pass" and then using Python import os and then DB_PWD=os.getenv("DB_PWD") still leaves it in RAM until you exit your shell after running the Python script. Probably the best answer is using an API call to an on-prem or cloud-based secret manager within your code, and using the retrieved value.
