A DevOps engineer is tasked with automating the deployment of service profiles in a Cisco UCS environment managed by UCS Manager. The primary requirements are that the automation solution must be declarative, idempotent, and easily integrated into an existing CI/CD pipeline that uses YAML for definitions. Which tool best satisfies all these requirements?
A network administrator is troubleshooting a PowerOn Auto Provisioning (POAP) failure on a new Nexus 9300 switch. The switch successfully obtains an IP address from DHCP but fails to download the Python configuration script from the TFTP server. The DHCP server is confirmed to be providing the correct script name and TFTP server IP. Which two potential issues are the most likely cause of this failure? (Choose two.)
An automation engineer needs to construct a REST API call to Cisco Intersight to retrieve all server profiles that are in an 'Unassigned' state. Based on the Intersight API documentation, the endpoint for server profiles is `/api/v1/server/Profiles` and it supports OData query options. Which API call correctly filters the results?
A data center operator is using model-driven telemetry on a Nexus 9500 switch to stream interface statistics to a collector. They observe high CPU utilization on the switch and determine that the telemetry process is the cause. The current configuration pushes data every 5 seconds for all 128 interfaces on a line card. Which action is the most effective way to reduce the CPU load caused by telemetry without losing critical visibility?
True or False: When using the Cisco ACI Cobra SDK to create a new Tenant, the configuration change is immediately pushed to the APIC upon object creation in the Python script.
A developer is writing a Python script to interact with a REST API. The API can sometimes take several seconds to respond, and the script must perform other tasks while waiting for the API response to avoid blocking. Which Python library and approach should be used to achieve this non-blocking, asynchronous behavior?
An administrator is attempting to run a Python script inside the NX-OS guest shell on a Nexus 9000 switch. The script fails because it depends on an external library that is not installed. What is the correct command to install the required library within the guest shell environment?
A financial services company is using Terraform to manage its Cisco ACI fabric. The security team mandates that all infrastructure changes must be reviewed and approved before being applied. The DevOps team uses a Git-based workflow. How can the team ensure that proposed ACI configuration changes are reviewed before they are implemented? ```mermaid flowchart TD A[Developer creates TF plan] --> B{Push to Git Repo}; B --> C[CI Server runs 'terraform plan']; C --> D{Review & Approve Plan Output}; D -- Approved --> E[CI Server runs 'terraform apply']; D -- Rejected --> F[Developer revises code]; F --> A; E --> G([End]); ```
A developer needs to ensure their Python automation project and its specific library dependencies can be reliably replicated on a different machine. The project uses the `requests` library version `2.25.1` and `netmiko` version `3.4.0`. What is the best practice for managing and documenting these dependencies?
Which two authentication mechanisms are commonly required when making programmatic calls to the Nexus Dashboard Fabric Controller (NDFC) REST API? (Choose two.)
