350-601 Automation Practice Test 7 — 15 Questions

Question 1

Which two of the following are valid methods to automate Nexus switch configuration using Python? (Choose two.)

Accepted Answer

Using the cisco_nxapi Python library. cisco_nxapi is a Python library for Nexus API. Guest Shell allows running Python scripts on-box. EEM uses Tcl, not Python natively. NETCONF uses Python via ncclient, but not natively on Nexus. Ansible is not Python library.

Answer

Using NETCONF with Python

Answer

Using Ansible with Python modules

Answer

Writing Python scripts for EEM applets

Question 2

Which three of the following are characteristics of the ACI Management Information Tree (MIT)? (Choose three.)

Accepted Answer

It is a hierarchical tree structure. The MIT is a hierarchical tree with objects like Tenant, AP, EPG, BD. Each object has a distinguished name (DN). The APIC REST API uses JSON/XML. SNMP is not used for ACI management. The MIT is not flat; it is hierarchical.

Answer

It can be accessed via SNMP

Answer

It is a flat database without hierarchy

Question 3

Which two of the following are benefits of using YANG data models for network automation? (Choose two.)

Accepted Answer

They enable network automation and multi-vendor interoperability. YANG models provide structured, standardized data models, enabling automation and vendor interoperability. They reduce manual CLI commands and allow validation. YANG is not tied to a specific transport.

Answer

They are only supported by Cisco devices

Answer

They eliminate the need for any CLI commands

Answer

They require the use of NETCONF exclusively

Question 4

An engineer wants to automate the configuration of VLANs on a Nexus switch using Ansible. Which module from the cisco.nxos collection should be used?

Accepted Answer

nxos_vlan. The nxos_vlan module is specifically designed to manage VLANs on Cisco NX-OS devices.

Answer

nxos_config

Answer

nxos_bgp

Answer

nxos_interface

Question 5

A DevOps team is implementing CI/CD for network configuration using Git. They want to ensure that any changes to the YANG-based configuration are automatically validated before merging. Which tool is used for network automation with YANG models and supports NETCONF/RESTCONF?

Accepted Answer

Terraform with netconf-client provider. Terraform can use RESTCONF/NETCONF providers, but Ansible with cisco.nxos collection also supports YANG; however, Terraform is declarative and fits CI/CD pipelines well.

Answer

Terraform with terraform-provider-aci

Answer

Python with cisco_nxapi library

Answer

Ansible with cisco.nxos collection

Question 6

In an ACI fabric, an automation engineer needs to create a new tenant with an application profile and EPG using the APIC REST API. The engineer decides to use the Cobra SDK for Python. Which statement about the Cobra SDK is true?

Accepted Answer

Cobra SDK provides Python classes for each object in the ACI MIT.. Cobra SDK provides Python bindings for the APIC REST API, allowing direct manipulation of the MIT.

Answer

Cobra SDK only supports JSON format for payloads.

Answer

Cobra SDK uses NETCONF to communicate with the APIC.

Answer

Cobra SDK requires the acitoolkit library to be installed separately.

Question 7

A network administrator wants to send NX-OS CLI commands to a Nexus switch via HTTP/HTTPS. Which API should be used?

Accepted Answer

NX-API CLI. NX-API CLI allows sending NX-OS commands via HTTP/HTTPS in either XML or JSON format.

Answer

NETCONF

Answer

RESTCONF

Answer

APIC REST API

Question 8

An engineer wants to run a Python script on a Nexus switch without copying it to the bootflash. The script interacts with the switch's CLI and file system. Which feature allows this?

Accepted Answer

Guest shell. Guest shell provides a Linux environment on Nexus where Python scripts can run directly.

Answer

OnEX

Answer

NX-API REST

Answer

EEM with Python applets

Question 9

Which statement accurately describes the APIC REST API?

Accepted Answer

It uses JSON over HTTPS and interacts with the MIT.. APIC REST API is a RESTful API that uses JSON over HTTPS and allows management of the ACI fabric.

Answer

It uses XML over SSH for communication.

Answer

It is only used for monitoring, not configuration.

Answer

It requires the use of the Cobra SDK.

Question 10

An engineer is writing an Ansible playbook to configure a Nexus switch. The playbook uses the cisco.nxos.nxos_config module. Which Ansible concept is used to ensure the playbook is idempotent?

Accepted Answer

The 'check_mode: yes' flag ensures the playbook only shows changes without applying them.. The 'check_mode' (or '--check') flag in Ansible allows dry-run to verify idempotency.

Answer

Idempotency is achieved by using the 'force' parameter.

Answer

Using 'gather_facts: no' makes the playbook idempotent.

Answer

Idempotency is guaranteed by default in Ansible.

Question 11

An automation engineer is using the cisco_nxapi Python library to configure a Nexus switch. Which step is required before using the library?

Accepted Answer

Enable NX-API on the Nexus switch with 'feature nxapi'.. The cisco_nxapi library uses NX-API, which must be enabled on the Nexus switch via 'feature nxapi'.

Answer

Configure a NETCONF session.

Answer

Generate an SSH key pair for authentication.

Answer

Install the library on the Nexus switch using pip.

Question 12

In an ACI environment, an automation script uses the acitoolkit Python library to create a new EPG. The script connects to the APIC using login credentials. After creating the EPG, what must be called to commit the changes?

Accepted Answer

session.push_to_apic(). acitoolkit uses a Session object; after making changes, the session's push_to_apic method must be called to commit.

Answer

session.save()

Answer

session.commit()

Answer

session.apply()

Question 13

Which protocol is used by NETCONF for transport?

Accepted Answer

SSH. NETCONF (RFC 6241) uses SSH as its transport protocol.

Answer

Telnet

Answer

HTTP

Answer

HTTPS

Question 14

An engineer wants to automate the configuration of BGP on a Nexus switch using Ansible. Which module from the cisco.nxos collection is appropriate?

Accepted Answer

nxos_bgp. The nxos_bgp module is designed to manage BGP configuration on NX-OS devices.

Answer

nxos_interface

Answer

nxos_config

Answer

nxos_vlan

Question 15

Which two statements about the Cisco NX-API REST interface are true? (Choose two.)

Accepted Answer

It can be used to send CLI commands.. NX-API REST supports JSON and XML over HTTP/HTTPS, and can be used to send CLI commands (via NX-API CLI) as well as structured data.

Answer

It only supports GET operations.

Answer

It requires the use of YANG models.

Answer

It uses SSH for transport.
