How many Select Two (Multi-Select) Questions questions are on this page?

This page has 20 Select Two (Multi-Select) Questions scenario questions for the 350-401 exam, each with detailed explanations and wrong-answer analysis.

How should I approach 350-401 scenario questions?

Read the full scenario before looking at the answer options. Identify the constraint or requirement in the scenario, then eliminate options that are generally true but wrong for this specific case. Scenario questions reward careful reading over pattern matching.

How to approach select two (multi-select) questions

Multi-select questions tell you to 'Choose TWO' or 'Choose THREE'. Getting partial credit is not a thing — you must select all correct answers with no incorrect ones. The stem always states how many to choose, so trust it. These questions require precision, not best-guess elimination.

Quick answer

Select Two (Multi-Select) Questions questions test whether you can apply the concept in context, not just recognise a definition.

How the topic appears in realistic exam-style scenarios.

Which detail in the question changes the correct answer.

How to eliminate plausible but wrong options.

How to connect the question back to the wider exam objective.

Which three statements about using Python for device inventory and data serialization in network automation are true? (Choose three.)

A
A Python script can read a YAML file containing device hostnames and IP addresses, then use that data to connect to each device and gather inventory information.
Correct because this is a common pattern: use PyYAML to load a YAML inventory file, iterate over devices, and use Netmiko or NAPALM to collect facts.
B
The json module in Python can be used to serialize a dictionary containing device inventory data into a JSON string for storage or transmission.
Correct because Python's built-in json module provides json.dumps() to convert Python objects (like dicts) into JSON strings, which is useful for saving inventory data or sending it to other systems.
C
CSV files can be parsed using Python's csv module to import device inventory data, such as hostname, IP, and credentials, into a script.
Correct because the csv module allows reading and writing CSV files, which are commonly used for inventory lists in network automation.
D
YAML files in Python cannot contain comments, so all inventory data must be described without explanatory text.
Why wrong: Incorrect because YAML supports comments using the '#' character, and Python's PyYAML library can parse files that include comments (though comments are not preserved when dumping).
E
JSON is always more human-readable than YAML for complex inventory structures.
Why wrong: Incorrect because YAML is often considered more human-readable due to its use of indentation and less verbose syntax; JSON can be harder to read for deeply nested structures.
