Cisco Automating Networks Using Cisco Platforms Exam Practice Test

Network automation combines Python programming with APIs, structured data, and repeatable workflows for interacting with network devices and services. This practice page samples practical concepts such as running code in virtual environments, resolving device names, handling input and files, and coordinating commands across multiple devices.

About the Cisco Automating Networks Using Cisco Platforms Exam

Automation work often requires choosing how software communicates with infrastructure and how it represents the intended state. JSON provides a language-independent way to exchange nested resource data, while vendor API client documentation helps clarify available methods and required arguments. Configuration comparisons can reveal differences between a device's current state and a saved target before changes are applied. Python skills also support reliable tooling: converting and validating input, using context managers to close files safely, and accepting flexible function arguments. Concurrent execution is useful when a workflow must contact several devices without waiting for each operation to finish in sequence. Consistent formatting and linting help teams detect style problems and common errors earlier. These skills support tasks such as building scripts, integrating APIs, checking device state, and making automation runs more repeatable.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A Python program uses a third-party module installed in a virtual environment. Which command pattern runs the program using the interpreter associated with that environment?

  1. AActivate or select the environment, then invoke its Python interpreter
  2. BRun the program with any system interpreter and assume it finds the environment's packages
  3. CRename the module file to match the environment directory
  4. DAdd the environment's package list to the program's output
Show answerCorrect answer: A

A virtual environment has its own interpreter and installed packages. Selecting or activating that environment ensures the program runs with the intended interpreter and dependencies.

Question 2

A network automation system needs to determine whether a device's management name resolves to an IP address before connecting. Which service is primarily responsible for that name resolution?

  1. ADNS
  2. BNTP
  3. CSyslog
  4. DSNMP
Show answerCorrect answer: A

The Domain Name System (DNS) maps hostnames to IP addresses and supports related name-resolution records. NTP synchronizes clocks, Syslog transports or records event messages, and SNMP is used for monitoring and management data.

Question 3

A network automation workflow must run a command on several devices concurrently rather than waiting for each device in sequence. Which approach most directly supports this?

  1. AUse asynchronous I/O or a concurrency framework
  2. BConvert every device name to uppercase
  3. CWrite the device list to a CSV file first
  4. DReplace loops with a single print statement
Show answerCorrect answer: A

Asynchronous I/O or an appropriate concurrency framework can overlap waiting on network operations, improving throughput when tasks are independent. The other choices do not provide concurrent execution.

Question 4

A network automation job needs to compare a device's current configuration with a saved intended configuration before deciding what to change. What is the most direct purpose of producing this comparison?

  1. AIdentify configuration differences that may need reconciliation
  2. BDetermine which DNS server answers fastest
  3. CEncrypt the saved configuration automatically
  4. DMeasure the physical cable length to the device
Show answerCorrect answer: A

Comparing current and intended configuration highlights discrepancies. An automation workflow can use those differences to decide whether and how to reconcile the device with the intended state.

Question 5

A Python program needs to ensure that a value is treated as an integer and report invalid input cleanly. What is a suitable approach?

  1. ACall int(value) inside a try/except block for ValueError
  2. BCompare the value's text length with a fixed number
  3. CUse print(value) to convert the value
  4. DAppend the value to a list and assume it is numeric
Show answerCorrect answer: A

int(value) converts valid integer text to an integer and raises ValueError for invalid input, which can be handled explicitly.

Question 6

A Python automation tool must work with a vendor's device API using an available client library. Which resource is most useful for discovering the library's supported methods and expected arguments?

  1. AThe library's API reference documentation
  2. BThe device's ARP table
  3. CA DNS zone file
  4. DA packet capture containing unrelated traffic
Show answerCorrect answer: A

An API reference documents the functions or classes a library exposes and the arguments they accept. It is the appropriate resource for understanding how to use a client library.

Question 7

A team wants to represent a collection of network resources in a way that is independent of a particular programming language. Which format is commonly used for structured data exchange and supports nested objects and arrays?

  1. AJSON
  2. BJPEG
  3. CMP3
  4. DZIP
Show answerCorrect answer: A

JSON is a language-independent text format for structured data, with objects and arrays that can represent nested information.

How to use this practice test

The free practice bank contains 50 questions; each session presents up to 20 random questions and displays results afterward. Use a session to identify which areas need more work, such as Python behavior, API documentation, structured data, name resolution, or multi-device execution. Review missed concepts before trying another set.

Preparation tips

  • Run a small Python script from a virtual environment and verify that its interpreter can import the installed third-party module.
  • Practice converting text input to an integer and handling invalid values with a clear exception path.
  • Compare a sample device configuration with an intended version, then identify which differences should trigger a change.
  • Read a vendor API client's documentation and map a method's arguments to the data your automation workflow must send.
  • Build a small workflow that resolves a hostname and runs independent device commands concurrently; inspect how failures are reported.
