    CCNA Exam Prep 63, Configuration Management — Ansible, Puppet, Chef
    2026/07/14
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - Ansible is agentless and uses a push model, making it ideal for network devices where agents cannot be installed. - Puppet and Chef are primarily agent-based and use a pull model, where nodes check in with a master server for configuration. - The CCNA exam tests your ability to select the correct tool based on scenario requirements, primarily agent-based versus agentless. - Key terminology to match: Ansible uses YAML Playbooks, Puppet uses Manifests, and Chef uses Recipes and Cookbooks. - Idempotence is a core concept ensuring operations result in the same system state, preventing unintended changes on subsequent runs.

  • CCNA Exam Prep 62, REST APIs — Methods, Status Codes, JSON

    CCNA Exam Prep 62, REST APIs — Methods, Status Codes, JSON
    2026/07/13
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - REST APIs use standard HTTP methods like GET (read), POST (create), PUT (replace), PATCH (partially update), and DELETE to manage network resources. - A critical exam trap is the difference between PUT, which replaces an entire resource, and PATCH, which performs a more efficient partial update. - HTTP status codes signal the outcome of an API request, such as 200 for success, 201 for resource creation, 401 for authentication failure, and 404 for a resource not found. - REST APIs are stateless, meaning every request must contain all necessary information, including an authentication token in the header. - Data payloads in modern network automation are typically formatted in JSON, a lightweight, human-readable key-value pair format.

    2026/07/12
    This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - The key differences between a distributed control plane in traditional networks and a centralized control plane in controller-based architectures. - How southbound APIs (e.g., NETCONF) are used for controller-to-device communication versus how northbound APIs (e.g., REST APIs) are used for controller-to-application communication. - The distinction between the physical underlay network and the virtual overlay network (e.g., VXLAN). - Common CCNA exam traps, such as the continued distribution of the data plane in SDN and the specific roles of Cisco DNA Center versus vManage. - A simple mnemonic to remember the direction and purpose of northbound and southbound APIs.
