NSE7 Enterprise Firewall and VDOMs Practice Question
An administrator is configuring a new VDOM on a FortiGate and needs to ensure that certain system resources are isolated for that VDOM. Which TWO settings must be configured to achieve resource isolation?
⚠ Common exam trap
A common mix-up: candidates confuse 'resource isolation' with 'traffic control' or 'storage limits', leading them to select bandwidth limit or disk quota instead of the correct system-level quotas (memory and CPU).

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
✓
Set memory quota
Setting a memory quota on a VDOM limits the amount of physical memory (RAM) the VDOM can consume, preventing it from starving other VDOMs or the root system. Option C is correct because setting a CPU quota caps the percentage of CPU time the VDOM can use, ensuring fair scheduling across VDOMs. Together, these two settings enforce resource isolation at the system level, which is required for multi-tenant or segmented environments.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set disk quota
Why it's wrong here
Disk quota is for log storage, not system resource isolation.
- ✓
Set memory quota
Why this is correct
Memory quota limits the memory usage for the VDOM.
- ✓
Set CPU quota
Why this is correct
CPU quota limits the CPU usage for the VDOM.
- ✗
Set bandwidth limit
Why it's wrong here
Bandwidth limits traffic, not system resources.
- ✗
Set session limit
Why it's wrong here
Session limit controls concurrent sessions but not system resources.
