Correct answer: GET /api/v1/server/Profiles?$filter=Status eq 'Unassigned'

This is the correct syntax for an OData query. The '$filter' parameter is used to specify the filtering condition, where the 'Status' property must be equal ('eq') to the string 'Unassigned'.

Correct answer: Increase the subscription sample interval from 5 seconds to 60 seconds.

The frequency of data collection and streaming is a primary driver of CPU usage. Increasing the sample interval (e.g., from 5 to 60 seconds) directly reduces how often the system must gather and push data, significantly lowering the CPU load. This is the most direct and effective method to control resource consumption while maintaining visibility, albeit at a lower resolution.

Correct answer: False

The statement is false. In the Cobra SDK workflow, you first create and modify Managed Objects (MOs) locally within your script. The changes are not sent to the APIC until you explicitly use a method like `c.addMo(tenant)` and then `c.commit(configReq)` to commit the configuration request. This allows for building a set of changes before sending them to the controller in a single transaction.

Correct answer: The `asyncio` library with the `aiohttp` client.

The `asyncio` library is Python's standard framework for writing single-threaded concurrent code using coroutines. Paired with the `aiohttp` library, which provides an asynchronous HTTP client, it allows the script to make an API call, `await` the response without blocking, and yield control to the event loop to perform other tasks. This is the ideal pattern for non-blocking I/O operations.

Correct answer: sudo pip install packagename

The NX-OS guest shell is a Linux environment where Python packages are managed using `pip`. To install packages system-wide within the shell, you need root privileges, which are obtained using `sudo`. Therefore, `sudo pip install ` is the correct command.

Correct answer: By integrating Terraform with a CI/CD pipeline that runs `terraform plan` on a pull request and requires peer approval before merging and applying.

This is the standard GitOps workflow for Terraform. When a developer submits a pull request, the CI/CD pipeline automatically runs `terraform plan`. The output of the plan, showing the exact changes to be made, is posted to the pull request for review. The changes are only applied (`terraform apply`) after the pull request is approved and merged, satisfying the security requirement for review and approval.

Correct answer: Use a virtual environment, install the dependencies, and generate a `requirements.txt` file using `pip freeze`.

This is the standard best practice. A virtual environment isolates the project's dependencies from the system and other projects. The `pip freeze > requirements.txt` command creates a file listing the exact packages and versions, which can then be used on another machine with `pip install -r requirements.txt` to perfectly replicate the environment.

Correct answers: A session token obtained via a login request.; A username and password sent with each request.

The standard workflow for NDFC API authentication involves sending a POST request with user credentials to a login endpoint. The response contains a session token (e.g., `Dcnm-Token`) that must be included in the headers of all subsequent API calls.

The initial login request to obtain the session token requires the user's username and password to be sent in the body of the POST request. This is the first step of the authentication process.

Correct answer: The OpenConfig BGP YANG model.

OpenConfig is a collaborative effort by network operators to create vendor-neutral YANG data models for network configuration and management. Using the OpenConfig BGP model allows the engineer to write automation scripts that can, in principle, configure BGP on devices from any vendor that supports the model, thus meeting the portability requirement.

Correct answer: To show the equivalent REST API calls for actions performed in the GUI.

The API Inspector's main purpose is to serve as a learning and development tool. It records actions taken in the graphical user interface and displays the corresponding REST API calls (including the URL, method, and JSON payload) that the GUI made to the APIC. This allows developers to easily learn how to perform tasks programmatically.
