The answer is that the developer’s resource allocation quota has been reached. This is the most likely cause because resource quotas are administrative limits set per user or project, which operate independently of the cluster’s actual capacity—so even when CPU and memory usage are below 50%, a quota can block a new cloud VM deployment. On the CompTIA A+ Core 2 220-1202 exam, this question tests your understanding of cloud resource management and the critical distinction between quotas (per-user ceilings) and total available resources (cluster capacity). A common trap is assuming that low overall utilization means no deployment restrictions exist, but quotas enforce governance regardless of free space. Remember the mnemonic: “Quota is a cap, not a map of capacity.”
220-1202 Virtualization and Cloud Technologies Practice Question
This 220-1202 practice question tests your understanding of virtualization and cloud technologies. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A company uses a private cloud for its development environment. A developer complains that they cannot deploy a new application because the cloud management portal shows a 'resource quota exceeded' error. The technician checks the cluster and finds that CPU and memory usage are below 50%. What is the most likely cause of the error?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Why wrong: Maintenance mode would prevent VMs from running, but the error is specifically about a quota, not host availability.
B
The storage pool is full
Why wrong: Storage fullness would cause a different error, and the scenario mentions CPU/memory are low, not storage.
C
The developer's resource allocation quota has been reached
Quotas limit how many resources a user can consume, regardless of total available capacity. The error indicates the developer hit their personal limit.
D
The virtual switch is not configured for the developer's VLAN
Why wrong: VLAN misconfiguration would cause network connectivity issues, not a quota-related deployment error.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The developer's resource allocation quota has been reached
Resource quotas are administrative limits set per user or project, independent of actual cluster utilization. Even with plenty of free resources, a quota can block deployment. This tests understanding of cloud resource management and the difference between quotas and capacity.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The hypervisor is in maintenance mode
Why it's wrong here
Maintenance mode would prevent VMs from running, but the error is specifically about a quota, not host availability.
✗
The storage pool is full
Why it's wrong here
Storage fullness would cause a different error, and the scenario mentions CPU/memory are low, not storage.
✓
The developer's resource allocation quota has been reached
Why this is correct
Quotas limit how many resources a user can consume, regardless of total available capacity. The error indicates the developer hit their personal limit.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Access ports place end devices into a single VLAN.
✗
The virtual switch is not configured for the developer's VLAN
Why it's wrong here
VLAN misconfiguration would cause network connectivity issues, not a quota-related deployment error.
Common exam traps
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.

Detailed technical explanation
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.
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
How this comes up in practice
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
