Question 401 of 500
Quick Answer
The answer is 9000, which is the recommended MTU value for HyperFlex storage data vNICs. This is because HyperFlex storage traffic relies on jumbo frames to maximize throughput and reduce CPU overhead; an MTU of 9000 allows larger packet sizes, minimizing fragmentation and improving storage I/O performance during cluster operations. On the Cisco DCCOR 350-601 exam, this question tests your understanding of HyperFlex networking best practices, often appearing in the context of UCS Manager or vSphere cluster creation workflows. A common trap is confusing the storage vNIC MTU with the management vNIC MTU, which typically uses the standard 1500—remember that storage data paths always require jumbo frames. Memory tip: think “9K for storage, 1.5K for management” to keep the values straight.
350-601 Compute Practice Question
This 350-601 practice question tests your understanding of compute. 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.
A UCS administrator is deploying a 3-node HyperFlex cluster with vSphere. Each node has a single vNIC for management and two vNICs for storage data traffic. During the cluster creation, the storage vNIC MTU must be configured. What is the recommended MTU value for the storage data vNICs in HyperFlex?

Correct answer & explanation
✓
9000
C is correct because HyperFlex storage data vNICs require jumbo frame support to optimize storage traffic performance. The recommended MTU value for these vNICs is 9000, which allows larger packet sizes and reduces CPU overhead for storage I/O operations. This value is consistent with Cisco's best practices for HyperFlex cluster deployments.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the specific recommended MTU value of 9000 for HyperFlex storage vNICs, and the trap here is that candidates may confuse it with the maximum jumbo frame size of 9216 supported by some switches, or assume the standard 1500 MTU is sufficient for storage traffic.
Detailed technical explanation
How to think about this question
Jumbo frames with an MTU of 9000 reduce the number of packets needed to transfer large storage data blocks, lowering CPU utilization and improving throughput. In HyperFlex, the storage data vNICs carry iSCSI or NVMe-over-Fabric traffic, and using 9000 MTU ensures compatibility with the underlying Cisco UCS fabric interconnects and switches. A real-world scenario where this matters is when deploying HyperFlex over a stretched cluster, where jumbo frames help maintain performance across longer distances.
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.
TExam Day Tips
- 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 350-601 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.
