A network engineering team is evaluating configuration management tools to automate Cisco IOS XE switch deployments. The architecture mandates that managed network devices must not require a persistent local management daemon or software agent, and all configuration task execution must be driven from a central control node using native management protocols and human-readable YAML files.

Which of the following operational characteristics correctly describe the selected configuration management tool? (Select TWO.)

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: The framework utilizes a push-based communication model where the control node initiates management sessions directly to target network devices.; Configuration tasks are defined in playbooks and executed across endpoints over standard SSH or NETCONF transport protocols.

Cevap

The configuration management mechanism described is Ansible, which uses a push-based communication model from a control node over standard transport protocols (SSH/NETCONF) with YAML playbooks and requires no agent software on target endpoints.
The scenario describes Ansible, which is unique among the three major configuration management tools for being completely agentless on target network devices. Ansible relies on a push-based model where the control node opens standard transport sessions (such as SSH or NETCONF) to execute tasks defined in YAML playbooks.

Adım Adım Çözüm

1
Analyze the architectural requirements stated in the scenario.
The requirements specify an agentless architecture, central control node driving execution, native management protocols (SSH/NETCONF), and YAML files.
Identifying these key attributes narrows the tool down to Ansible, distinguishing it from agent-based pull systems like Puppet and Chef.
2
Evaluate the delivery mechanism and transport method of Ansible.
Ansible uses a push model where the control node initiates connections to managed devices using SSH or NETCONF.
Because no persistent agent daemon is installed on managed network switches, Ansible relies on native network management transport protocols.
3
Verify file structure and contrast with alternative mechanisms.
Ansible uses YAML playbooks. In contrast, Puppet uses Puppet DSL manifests over TCP 8140 (pull), and Chef uses Ruby recipes/cookbooks over TCP 443 (pull).
This confirms that options describing push-based execution over SSH/NETCONF and YAML playbooks are correct, while options referring to TCP 8140 pull operations or Ruby cookbooks describe Puppet and Chef.

Soru 2Soru →

A network architect is designing an automated configuration management solution for a large Enterprise network containing hundreds of Cisco IOS XE routers and NX-OS switches. The architecture requirements mandate minimizing device-level software overhead by avoiding persistent agent installations, using standard SSH/NETCONF protocol transport, leveraging YAML-formatted state files, and initiating configuration updates using a push-based model from a control node. Which configuration management tool satisfies all specified requirements, and which operational characteristics define its framework?

Cevabı ve açıklamayı göster

Cevap: Ansible, because it functions agentlessly over SSH or NETCONF using a push-based model to execute YAML-defined playbooks without requiring client software on managed devices.

Cevap

Ansible satisfies all requirements because it operates agentlessly over standard SSH or NETCONF transport, uses a push model initiated by the control node, and defines configuration tasks using YAML playbooks.
The correct answer accurately identifies Ansible's core architectural traits: it is agentless, uses SSH or NETCONF transport protocols, operates on a push model initiated by the administrator/control node, and uses readable YAML-formatted playbooks.

Adım Adım Çözüm

1
Analyze architecture requirement 1: Agentless operation over standard transport (SSH/NETCONF).
Ansible is inherently agentless for network devices, using native SSH or NETCONF sessions. Puppet and Chef typically rely on agent-based pull models or agent proxy daemons.
Eliminating agent installation on network switches/routers requires a tool designed for agentless management.
2
Analyze architecture requirement 2: Push-based execution vs Pull-based execution.
Ansible pushes configuration tasks from the control node to target devices upon command. Puppet and Chef nodes default to pulling configuration updates periodically from a central server.
Push models allow immediate targeted deployment from the control system without waiting for agent polling intervals.
3
Analyze architecture requirement 3: Data format / configuration structure.
Ansible uses YAML for its Playbooks. Puppet uses Puppet DSL (Manifests), and Chef uses Ruby DSL (Recipes/Cookbooks).
Matching the specified file format confirms Ansible as the correct mechanism.

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

Cevabı ve açıklamayı göster

Cevap: Ansible

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.

A network security policy requires that all configuration management operations across remote branch routers strictly prevent inbound session initiation from central management servers to remote devices. Outbound HTTPS traffic on TCP port 443 initiated by target devices toward the central server is permitted. Which configuration management tool natively meets these architectural constraints while utilizing Ruby-based files to define system state?

Cevabı ve açıklamayı göster

Cevap: Chef, because it uses an agent-based pull architecture operating over TCP port 443 and defines configurations using Ruby DSL recipes.

Cevap

Chef natively operates using an agent-based pull architecture over TCP port 443 (HTTPS) and relies on Ruby-based recipes contained within cookbooks to define device configuration states.
Chef employs an agent installed on managed devices that initiates outbound communication to the central Chef Server over TCP port 443 (HTTPS) to pull its configuration state. Configurations in Chef are authored using a Ruby-based Domain-Specific Language (DSL) organized into recipes and cookbooks, perfectly matching both the port and architectural requirements.

Adım Adım Çözüm

1
Analyze the operational direction constraint (inbound vs. outbound).
Since security policies prohibit inbound sessions initiated by the central server, the configuration management system must use a pull-based architecture where the managed node initiates outbound connections.
Chef and Puppet both natively use agent-based pull models, while Ansible primarily uses a push model (where the control node initiates SSH/NETCONF inbound to managed nodes).
2
Evaluate the required transport port and configuration definition language.
Chef client agents initiate outbound HTTPS requests to the Chef server over standard TCP port 443 and parse configuration definitions written in Ruby DSL (recipes/cookbooks). Puppet typically uses TCP port 8140 for agent-master pull communications.
Identifying both the network protocol/port and the underlying formatting language isolates Chef as the correct tool.
