300-420 Question 75

Select 3

An enterprise network architect is tasked with designing an infrastructure that enables seamless integration of diverse network devices and applications. They decide to leverage platform abstraction techniques to reduce operational complexity and improve programmability. Which of the following techniques are considered platform abstraction methods in this context?

  1. A

    Using REST APIs to enable communication between network devices and applications

  2. B

    Implementing a centralized controller for managing distributed network devices

  3. C

    Configuring VLANs to segment traffic within the network

  4. D

    Leveraging data models like YANG for standardized device configuration and management

  5. E

    Utilizing SNMP for real-time network device monitoring

Show answer and explanation

Correct answers: A, B, D

Explanation

Platform abstraction techniques focus on simplifying and standardizing interactions between network infrastructure and applications. This includes enabling programmability, centralized management, and the use of standardized data models. REST APIs, centralized controllers, and YANG data models are all critical components of platform abstraction, as they allow for abstraction of device-specific complexity, making networks easier to manage and integrate with higher-level applications.

  • A. Correct.

    Using REST APIs is a key platform abstraction technique, allowing applications to communicate with network devices in a standardized and simplified manner.

  • B. Correct.

    A centralized controller abstracts the complexity of distributed network devices, enabling easier programmability and orchestration, which is a core principle of platform abstraction.

  • C. Incorrect.

    Configuring VLANs is a network segmentation method, not a platform abstraction technique. It does not simplify or abstract the management of underlying devices.

  • D. Correct.

    YANG data models provide a standardized way to model and manage network device configurations, which is a cornerstone of platform abstraction.

  • E. Incorrect.

    SNMP focuses on network monitoring and does not inherently provide platform abstraction capabilities for programmability or operational simplification.
