Quick Answer
The answer is lock, as it prevents other NETCONF sessions from modifying a datastore. This operation is essential for maintaining data integrity during configuration changes, ensuring exclusive write access by locking the entire datastore against concurrent edits from other sessions. On the ENCOR 350-401 exam, you will often see NETCONF operations matching tasks that test your ability to distinguish between retrieval actions like get and get-config versus modification actions like edit-config and commit. A common trap is confusing lock with edit-config—remember that lock is a prerequisite for safe editing, not the edit itself. For the drag-and-drop format, focus on the action’s purpose: get retrieves everything, get-config retrieves only configuration, edit-config modifies, commit applies candidate changes, and lock secures the datastore. Memory tip: think of lock as the “bouncer” that keeps other sessions out while you work.
350-401 REST APIs and Data Models Practice Question
This 350-401 practice question tests your understanding of rest apis and data models. 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.
Drag and drop each NETCONF operation on the left to its matching action on the right.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
get: Retrieve operational state and configuration data
get retrieves operational state and configuration, get-config retrieves only configuration, edit-config modifies configuration, commit applies candidate changes, and lock prevents other sessions from modifying the datastore.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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 350-401 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.

Same concept, more angles
1 more ways this is tested on 350-401
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Drag and drop each NETCONF operation on the left to its action on the right.
medium- ✓ P1.get: Retrieve running configuration and state data
- ✓ P2.get-config: Retrieve configuration from a specific datastore
- ✓ P3.edit-config: Modify the target configuration datastore
- ✓ P4.commit: Confirm a candidate configuration as the new running config
- ✓ P5.lock: Prevent other NETCONF sessions from altering a datastore
Why P1: Correct pairings: get retrieves running config and state data; get-config retrieves a specific datastore; edit-config modifies configuration; commit confirms a candidate configuration; lock prevents other sessions from modifying a datastore.
