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.
An engineer needs to deploy a stateless UCS B-series blade with a boot from SAN configuration. Which components must be defined in the service profile to achieve this?
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
✓
vHBA and WWPN
For a stateless UCS B-series blade with boot from SAN, the service profile must define a vHBA (virtual Host Bus Adapter) with a WWPN (World Wide Port Name). The WWPN is used by the SAN fabric to identify the server and present the correct LUN for booting, enabling stateless boot without local storage. iSCSI and MAC addresses are irrelevant for Fibre Channel SAN boot, and local disk configuration is not used in a stateless boot-from-SAN design.
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 distinction between vNIC (Ethernet) and vHBA (Fibre Channel) in boot-from-SAN scenarios, leading candidates to mistakenly choose vNIC and MAC address when the question specifies SAN boot.
Detailed technical explanation
How to think about this question
In UCS Manager, a vHBA is a virtual Fibre Channel adapter that inherits a WWPN from a WWPN pool or is statically assigned; this WWPN is registered with the SAN switch (e.g., Cisco MDS) via Fabric Login (FLOGI) to enable zoning and LUN mapping. The boot-from-SAN policy in the service profile specifies the target WWPN and LUN ID, and the UCS fabric interconnect (FI) performs FCoE encapsulation to transport Fibre Channel frames over the Ethernet uplink to the SAN. A common real-world scenario is using persistent WWPNs to ensure the same LUN is presented after blade replacement, maintaining statelessness.
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.
