The answer is that the physical switches must support jumbo frames and the VMkernel port must have its MTU configured to 9000. These two prerequisites are essential because jumbo frames operate at the network layer, where the physical switch must be capable of forwarding larger-than-standard Ethernet frames without fragmentation, and the VMkernel port—the host’s software interface for storage traffic—must be explicitly set to an MTU of 9000 to match the switch’s capability. On the VMware Certified Professional Data Center Virtualization VCP-DCV exam, this concept tests your understanding of end-to-end network consistency; a common trap is assuming the storage array or guest OS needs configuration, but jumbo frames on a vSphere host for storage traffic are purely a host-to-switch concern. Remember the memory tip: “Switch and VMkernel, not array or guest”—the two prerequisites always involve the physical network infrastructure and the host’s own networking stack, never the storage target or virtual machines.
VCP-DCV Configure and Manage vSphere Storage Practice Question
This VCP-DCV practice question tests your understanding of configure and manage vsphere storage. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 TWO of the following are prerequisites for enabling jumbo frames on a vSphere host for storage traffic?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The VMkernel port must be configured with MTU 9000
Jumbo frames require physical switch support and VMkernel port MTU configuration. The storage array, guest OS, and vCenter do not directly affect host-level jumbo frame operation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 virtual machine guest OS must support jumbo frames
Why it's wrong here
Guest OS support is irrelevant for storage traffic jumbo frames.
✓
The VMkernel port must be configured with MTU 9000
Read the scenario before looking for a memorised answer.
✗
The storage array must support jumbo frames
Why it's wrong here
Not required for host-level jumbo frames.
✗
The vCenter Server must be configured for jumbo frames
Why it's wrong here
vCenter configuration is not required.
✓
The physical switches must support jumbo frames
Why this is correct
Switches must pass jumbo frames end-to-end.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the VCP-DCV exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
