Zorluk: KolayCapabilities of Configuration Management Mechanisms (Puppet, Chef, Ansible)

Which automation tool uses an agentless architecture to push network configurations to managed devices over SSH?

  1. AnsibleCevap
  2. B
    Puppet
  3. C
    Chef
  4. D
    SaltStack

Cevap

Ansible is the configuration management tool that operates using an agentless model and relies on SSH to push configurations to network devices.
The option selecting Ansible is correct because Ansible operates in an agentless fashion using SSH (or NETCONF/RESTCONF) to push YAML-defined configurations (Playbooks) directly from a control workstation to target network switches and routers.

Adım Adım Çözüm

1
Identify the key operational requirements in the question: agentless architecture and SSH push mechanism.
The target tool must not require agent software on network routers/switches and must use standard SSH transport.
Cisco network devices often run proprietary operating systems (such as IOS XE) where installing third-party agent software is difficult or unsupported.
2
Evaluate Ansible against these requirements.
Ansible uses Playbooks written in YAML, runs centrally on a control node, and connects to target devices over SSH without installing any agent on the target.
Ansible's native design is inherently agentless and push-based.
3
Evaluate Puppet and Chef against these requirements.
Both Puppet and Chef rely primarily on client/agent software installed on managed hosts to pull configurations periodically.
Puppet uses Manifests/Puppet Agent and Chef uses Recipes/Chef Client.
