Free Practice Questions for Cisco 350-601 Exam

The correct answer is D. A modular Cisco Nexus 9000 Series switch is designed with redundant supervisor capabilities, which allows the platform to perform an In-Service Software Upgrade (ISSU) with minimal or no traffic disruption when the hardware, software release, and features all meet ISSU compatibility requirements. The modular architecture supports stateful control-plane switchover and coordinated module upgrade behavior, which is the key difference from a typical nonmodular or fixed-form-factor switch.

This is why option D is correct: the modular platform can maintain forwarding while the supervisors transition during the upgrade process. By contrast, option A is backwards, because modular chassis are the platforms most associated with nondisruptive upgrade capability. Option B

The correct answer is A because Cisco Nexus 9000 Series switches use JSON-RPC 2.0 format for NX-API requests when interacting programmatically. In this format, the required fields include jsonrpc, method, params, and id. To retrieve operational or configuration data using a show command, Cisco specifies the use of the method cli_show, which is designed for read-only commands such as show running-config.

The params section must include the command (cmd) and the API version (version: 1). This aligns with Cisco NX-API documentation, where cli_show ensures that the output is returned without modifying the system.

Option D is incorrect because the method cli is used for configuration commands, not show commands. Options B and C are invalid because they use JSON-RPC 1.0 format, which is not supported in modern NX-API implementations for Nexus 9000 switches.

Therefore, the properly structured JSON-RPC 2.0 request using cli_show is required to retrieve the running configuration, making A the correct answer.

The correct answer is C. Ansible because it is the one option that matches all three stated requirements at the same time. Official Ansible documentation describes Ansible as an agentless automation tool installed on a control node, and states that it manages remote systems over SSH without requiring additional daemons or software on the managed nodes. Ansible documentation also states that its playbooks are written in YAML, which is intended to be easier for humans to read and write, making it a strong fit for teams with limited scripting experience.

The other options do not fit as cleanly. Chef can use SSH in agentless mode, but Chef’s core model is based on Chef Infra Client, which is an agent, and its automation logic is built around recipes rather than simple declarative YAML playbooks. Puppet supports declarative configuration and can use SSH through Bolt, but Puppet commonly relies on installed agents in standard deployments. PowerShell is primarily a scripting language, not the best match for the requirement for an easy-to-read declarative orchestration tool. Therefore, Ansible is the best and verified choice.
