VCP-DCV vSphere Performance and Scaling Practice Question
An administrator is planning a vMotion migration and wants to minimize the performance impact on the virtual machines during the migration. Which network configuration is recommended?
Answer choices
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
✓
Create a dedicated VMkernel interface with at least 10 GbE throughput for vMotion.
A dedicated VMkernel interface for vMotion isolates migration traffic from other network traffic, reducing contention and ensuring consistent performance. A minimum of 10 GbE is recommended to handle the high throughput demands of vMotion, especially for large VMs. Option B is incorrect because using the default management interface can lead to resource contention and performance degradation. Option C is incorrect because a single 1 GbE interface for both vMotion and management is likely insufficient and causes competition. Option D is incorrect because jumbo frames alone do not address the contention issue; keeping vMotion on the management network still causes competition.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create a dedicated VMkernel interface with at least 10 GbE throughput for vMotion.
Why this is correct
Dedicated high-speed interface minimizes performance impact.
- ✗
Use the default management VMkernel interface for vMotion traffic.
Why it's wrong here
Mixing traffic types can cause congestion.
- ✗
Configure a single 1 GbE interface for both vMotion and management traffic.
Why it's wrong here
1 GbE may be a bottleneck.
- ✗
Enable jumbo frames on all interfaces, but keep vMotion on the management network.
Why it's wrong here
Jumbo frames help but dedicated interface is better.
