- A
--- - name: Configure interface description hosts: R1 gather_facts: no tasks: - name: Add description to Gi0/0 ios_config: lines: - description Link to Core parents: interface GigabitEthernet0/0
This playbook correctly uses the ios_config module with the 'lines' parameter to specify the configuration command and the 'parents' parameter to set the interface context. The YAML syntax is valid, and the playbook can be run with ansible-playbook.
- B
--- - name: Configure interface description hosts: R1 gather_facts: no tasks: - name: Add description to Gi0/0 ios_config: lines: - interface GigabitEthernet0/0 - description Link to Core
Why wrong: This is incorrect because the ios_config module does not support entering interface configuration mode by including the 'interface' command in the 'lines' list. The 'parents' parameter must be used to specify the parent configuration context.
- C
--- - name: Configure interface description hosts: R1 gather_facts: no tasks: - name: Add description to Gi0/0 ios_command: commands: - configure terminal - interface GigabitEthernet0/0 - description Link to Core
Why wrong: This is incorrect because the ios_command module is used for sending exec commands, not for configuration. The ios_config module is specifically designed for configuration changes and ensures idempotency.
- D
--- - name: Configure interface description hosts: R1 gather_facts: no tasks: - name: Add description to Gi0/0 ios_config: lines: - description Link to Core parents: GigabitEthernet0/0
Why wrong: This is incorrect because the 'parents' parameter requires the full interface configuration command, including the 'interface' keyword. Simply specifying 'GigabitEthernet0/0' is not valid; it must be 'interface GigabitEthernet0/0'.
Quick Answer
The correct answer is the playbook using the ios_config module with the parents parameter set to interface GigabitEthernet0/0 and the lines parameter containing the description command. This is correct because the ios_config module operates in configuration mode, and the parents parameter allows you to enter a specific configuration context—in this case, the interface subconfiguration mode—before applying the lines. On the CCNA 200-301 v2 exam, this tests your understanding of how Ansible interacts with Cisco IOS devices, specifically that interface descriptions are configured under the interface, not globally. A common trap is forgetting the parents parameter, which would apply the description to the global configuration instead, causing a syntax error. Remember the memory tip: "Parents put you in the right place"—just as you need to type interface Gi0/0 before description in the CLI, the parents parameter tells Ansible to enter that sub-mode first.
CCNA AI and Network Operations Practice Question
This 200-301 practice question tests your understanding of ai and network operations. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
You are connected to the console of R1, a Cisco router that is part of a larger network. The network operations team uses Ansible to manage configurations. You need to write an Ansible playbook that configures an interface description on R1. The playbook should use the ios_config module.

Correct answer & explanation
--- - name: Configure interface description hosts: R1 gather_facts: no tasks: - name: Add description to Gi0/0 ios_config: lines: - description Link to Core parents: interface GigabitEthernet0/0
The playbook uses the ios_config module to add the description line under the interface configuration. The 'parents' parameter sets the context to 'interface GigabitEthernet0/0'. The playbook must be saved as a .yml file and run with ansible-playbook.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

--- - name: Configure interface description hosts: R1 gather_facts: no tasks: - name: Add description to Gi0/0 ios_config: lines: - description Link to Core parents: GigabitEthernet0/0
Why it's wrong here
This is incorrect because the 'parents' parameter requires the full interface configuration command, including the 'interface' keyword. Simply specifying 'GigabitEthernet0/0' is not valid; it must be 'interface GigabitEthernet0/0'.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.
✓--- - name: Configure interface description hosts: R1 gather_facts: no tasks: - name: Add description to Gi0/0 ios_config: lines: - description Link to Core parents: interface GigabitEthernet0/0Correct answer▾
Why this is correct
This playbook correctly uses the ios_config module with the 'lines' parameter to specify the configuration command and the 'parents' parameter to set the interface context. The YAML syntax is valid, and the playbook can be run with ansible-playbook.
✗--- - name: Configure interface description hosts: R1 gather_facts: no tasks: - name: Add description to Gi0/0 ios_config: lines: - interface GigabitEthernet0/0 - description Link to CoreWrong answer — click to see why▾
Why this is wrong here
The specific factual error: The 'lines' parameter should only contain the configuration commands to be applied under the parent context, not the parent command itself.
Why candidates choose this
Candidates might think that including the 'interface' command in the lines list would work, similar to how one would type commands in the CLI sequentially.
✗--- - name: Configure interface description hosts: R1 gather_facts: no tasks: - name: Add description to Gi0/0 ios_command: commands: - configure terminal - interface GigabitEthernet0/0 - description Link to CoreWrong answer — click to see why▾
Why this is wrong here
The specific factual error: The ios_command module does not handle configuration mode properly and is not intended for configuration tasks; it sends commands and returns output without state management.
Why candidates choose this
Candidates might confuse ios_command with ios_config, thinking that any command can be sent via ios_command, including configuration commands.
✗--- - name: Configure interface description hosts: R1 gather_facts: no tasks: - name: Add description to Gi0/0 ios_config: lines: - description Link to Core parents: GigabitEthernet0/0Wrong answer — click to see why▾
Why this is wrong here
The specific factual error: The 'parents' parameter expects the exact command that enters the configuration context, such as 'interface GigabitEthernet0/0', not just the interface name.
Why candidates choose this
Candidates might assume that the 'parents' parameter only needs the interface name, similar to how some other automation tools might accept abbreviated context identifiers.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Trap categories for this question
Keyword trap
This is incorrect because the 'parents' parameter requires the full interface configuration command, including the 'interface' keyword. Simply specifying 'GigabitEthernet0/0' is not valid; it must be 'interface GigabitEthernet0/0'.
Command / output trap
This is incorrect because the ios_config module does not support entering interface configuration mode by including the 'interface' command in the 'lines' list. The 'parents' parameter must be used to specify the parent configuration context.
Detailed technical explanation
How to think about this question

KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 200-301 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
