Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
Before applying a major patch to a virtual machine, the administrator wants a quick way to return the VM to its exact pre-change state if the patch fails. What should the administrator create?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
A full backup to removable media
A backup is useful for recovery, but it is slower than a snapshot for rapid rollback.
B
Best answer
A snapshot of the virtual machine
A snapshot captures the VM state at a specific moment, making rollback fast after a failed patch.
C
Distractor review
A separate VLAN for the virtual machine
A VLAN helps network segmentation, but it does not preserve the VM's system state.
D
Distractor review
A digital certificate for the patch server
Certificates help trust and authentication, but they do not provide restore points for a VM.
Common exam trap
Common exam trap: an active trunk can still block the VLAN you need
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.
Technical deep dive
How to think about this question
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.
KKey Concepts to Remember
- Access ports place end devices into a single VLAN.
- Trunk ports carry multiple VLANs between switches.
- Allowed VLAN lists decide which VLANs can cross a trunk.
- Native VLAN mismatch can create confusing symptoms.
TExam Day Tips
- Use show vlan brief to verify access VLANs.
- Use show interfaces trunk to verify trunk state and allowed VLANs.
- Do not treat every same-VLAN issue as a routing problem.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Access ports place end devices into a single VLAN.
What is the correct answer to this question?
The correct answer is: A snapshot of the virtual machine — A snapshot is the best choice when the goal is a quick rollback to a known point in time before a change. In virtualization, snapshots preserve the VM’s state, letting the administrator recover rapidly if a patch causes problems. This is especially useful for short-term change control and testing, though it is not a substitute for regular backups. Why others are wrong: A full backup is important for longer-term recovery, but it is not the fastest way to revert a VM after a failed patch. A VLAN only affects network placement. A certificate supports trust and authentication, but it does not capture system state or enable rollback.
