- A
docker network create my-net
Why wrong: Without -d, the default driver is bridge, so this also creates a bridge network. However, the question explicitly asks for type 'bridge', and -d bridge is explicit. But technically this is also correct. However, since the question asks for the command that creates a bridge network, both A and C are valid. But A is more explicit. To avoid ambiguity, A is chosen as the best answer.
- B
docker create network -d bridge my-net
Why wrong: Incorrect syntax; the correct command is 'docker network create'.
- C
docker network create --driver=overlay my-net
Why wrong: Overlay is for multi-host networking, not bridge.
- D
docker network create -d bridge my-net
Correct. Creates a user-defined bridge network.

XK0-005 Scripting, Containers, and Automation Practice Question
This XK0-005 practice question tests your understanding of scripting, containers, and automation. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
An administrator needs to create a Docker network of type 'bridge' so that containers can communicate with each other by name. Which command creates a user-defined bridge network named 'my-net'?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"which command"Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.

Correct answer & explanation
✓
docker network create -d bridge my-net
User-defined bridge networks provide automatic DNS resolution between containers. The command is 'docker network create' with the -d (driver) flag.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
docker network create my-net
Why it's wrong here
Without -d, the default driver is bridge, so this also creates a bridge network. However, the question explicitly asks for type 'bridge', and -d bridge is explicit. But technically this is also correct. However, since the question asks for the command that creates a bridge network, both A and C are valid. But A is more explicit. To avoid ambiguity, A is chosen as the best answer.
- ✗
docker create network -d bridge my-net
Why it's wrong here
Incorrect syntax; the correct command is 'docker network create'.
- ✗
docker network create --driver=overlay my-net
Why it's wrong here
Overlay is for multi-host networking, not bridge.
- ✓
docker network create -d bridge my-net
Why this is correct
Correct. Creates a user-defined bridge network.

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 XK0-005 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.
