A customer has a skilled internal DevOps team with extensive Python programming knowledge. Which HPE Aruba Networking CX switches would you recommend for the customer to support self-made or HPE Aruba Networking-provided scripts for onboard analytics?
Answer(s): B
Why CX 6200 is the optimal choiceNative Python-compatible automation – ArubaOS-CX on the CX 6200 series exposes a full-featured, REST-based API that can be called directly with Python (or any language that speaks HTTP). This allows the DevOps team to run self-authored scripts for provisioning, analytics, and telemetry without third-party wrappers. Onboard analytics framework – The CX 6200 includes built-in support for HPE Aruba Network Analytics (AI-driven insights) and the Aruba Central service, both of which can be invoked programmatically via the same Python API. This gives the customer immediate access to pre-built analytics scripts as well as the ability to extend them. Sufficient compute and memory – The switch’s ARM-based CPU and 4 GB of RAM can execute Python agents locally, enabling “on-switch” analytics (e.g., packet-level statistics, flow-based reporting) without relying on an external controller. Scalable management model – With up to 48 × 10/25 GbE ports and Stacking, the CX 6200 can be managed as a single logical entity, simplifying script orchestration across the fabric. Consistent OS & SDK – ArubaOS-CX provides a unified SDK (Python SDK, Ansible modules) that works across the CX 6000-series portfolio, ensuring that scripts written for the CX 6200 will also work on larger CX 6000 chassis if future scaling is needed.Why the other options are less suitableCX 6100 – Entry-level platform; its API surface is limited and it lacks the on-switch processing capability needed for real-time Python-driven analytics. CX 4100i – Targeted at modular, high-port-density deployments; while powerful, it does not expose a dedicated Python scripting interface for analytics and is oriented more toward hardware stacking than script-centric automation. CX 6000 – A chassis-based solution that requires additional line cards and external controllers for full API functionality; it does not provide native Python support on the switch itself, making on-switch script execution cumbersome.Result – The CX 6200 uniquely combines a robust, Python-friendly API, built-in analytics integration, and enough on-device resources to run custom scripts, making it the best fit for a DevOps-savvy environment that wants to leverage both HPE-provided and self-created analytics code.

Answer(s): A
The HPE Aruba Networking Fabric Composer is being proposed to manage existing CX switches in a customer environment. Which protocol does the AFC use to communicate with the switches?
Answer(s): A – APIThe HPE Aruba Networking Fabric Composer (AFC) interacts with existing Aruba CX switches through the Aruba CX Application Programming Interface (API) . The API provides a modern, programmatic abstraction that uses HTTP-based RESTful calls, JSON payloads, and authentication tokens. This design enables the Composer to issue centralized configuration, monitoring, and orchestration commands across many switches without relying on traditional network management protocols that are primarily “read-only” or require separate management channels.Why the other choices are less suitableSSH – Secure Shell is an interactive, terminal-oriented protocol primarily used for manual device access and scripting of CLI commands. AFC is designed for automated, programmatic management of many devices simultaneously, which SSH does not natively support at scale. Telnet – Like SSH, Telnet is an interactive, character-based protocol that lacks robust security, session management, and programmatic integration capabilities required for large-scale orchestration. SNMPv3 – SNMP is a standard for network monitoring and basic device health data exchange. While AFC can pull some metrics via SNMP, its primary control and configuration functions rely on the richer, more explicit API semantics, not just simple variable polling.Thus, the API is the only option that directly matches the architectural requirement for centralized, programmatic management of CX switches by the Fabric Composer.

You would like to monitor your CX switches from your existing Network Management System using SNMP and ensure the data is encrypted. Which version should you enable on the switches?
SNMP v3 is the only version that incorporates both authentication and encryption (via user-based security models), making it the only choice that can secure SNMP data transmitted to a Network Management System. SNMP v2 and SNMP v2c rely solely on plain-text community strings for authentication and provide no built-in confidentiality, so the data would remain exposed. SNMP v4 does not exist in the standards; only v1, v2c, and v3 are defined, so option D is invalid.
