This AZ-400 practice question tests your understanding of design and implement a source control strategy. 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.
Which THREE are common Git branching strategies used by development teams? (Select THREE.)
GitFlow
GitFlow uses develop and feature branches.
Trunk-based development
Trunk-based development uses short-lived branches and frequent merges to main.
Feature branching
Feature branching creates branches for each feature.
Monorepo
Why wrong: Monorepo is a repository structure, not a branching strategy.
Centralized version control
Why wrong: This is a VCS model (e.g., TFVC), not a Git branching strategy.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
GitFlow
GitFlow, Trunk-based development, and Feature branching are common strategies. Centralized version control is not a Git branching strategy. Monorepo is a repository structure, not a branching strategy.
Key principle: A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
GitFlow
Why this is correct
GitFlow uses develop and feature branches.
Related concept
Access ports place end devices into a single VLAN.
Trunk-based development
Feature branching
Why this is correct
Feature branching creates branches for each feature.
Related concept
Access ports place end devices into a single VLAN.
Monorepo
Why it's wrong here
Monorepo is a repository structure, not a branching strategy.
Centralized version control
Why it's wrong here
This is a VCS model (e.g., TFVC), not a Git branching strategy.
Common exam traps
A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.
Detailed technical explanation
VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.
Key takeaway
A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Review VLAN allowed lists, native VLAN mismatch detection, and how to verify VLAN membership with show vlan brief and show interfaces trunk. Then practise related AZ-400 questions on switching, trunking, and access-port configuration.
