Quick Answer
The correct answer is a WWPN pool for the vHBA and a SAN boot policy with the target WWPN. These two items are required because Fibre Channel SAN boot in UCS relies on the vHBA having a unique World Wide Port Name from a WWPN pool to log into the fabric, while the SAN boot policy specifies the exact target storage WWPN and LUN from which the ESXi host will boot. On the Cisco DCCOR 350-601 exam, this configuration tests your understanding of how UCS abstracts physical hardware through service profiles, and a common trap is confusing the WWPN pool with a MAC pool or omitting the target WWPN in the boot policy. Remember that the vHBA needs its identity (WWPN) from the pool, and the boot policy needs the destination (target WWPN)—think of it as “who you are” and “where you’re going.” A helpful mnemonic is “Pool for the Path, Policy for the Target.”
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 configuring a service profile for a VMware ESXi host. Which TWO of the following configuration items must be included to enable Fibre Channel SAN boot?
QoS policy for vHBA
Why wrong: QoS policy is optional and not required for boot functionality.
WWPN pool for vHBA
A WWPN pool provides the WWPNs for the vHBA that connects to the SAN.
vNIC with MAC pool
Why wrong: vNIC is for Ethernet, not for storage boot.
FCoE VLAN configuration
Why wrong: FCoE is not required for native Fibre Channel SAN boot.
SAN boot policy with target WWPN
The SAN boot policy defines the boot target LUN and WWPN.

Correct answer & explanation
WWPN pool for vHBA
For Fibre Channel SAN boot on a UCS-managed VMware ESXi host, the service profile must include a WWPN pool for the vHBA (Option B) to assign unique World Wide Port Names, and a SAN boot policy specifying the target WWPN (Option E) to define the storage target from which the host boots. These two elements are essential because the vHBA requires a WWPN for fabric login, and the boot policy directs the host to the correct LUN on the SAN.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Cisco often tests the distinction between Fibre Channel SAN boot and FCoE SAN boot, leading candidates to incorrectly select FCoE VLAN configuration (Option D) when the question explicitly states 'Fibre Channel SAN boot' without mentioning FCoE.
Detailed technical explanation
In UCS, a vHBA is a virtual Fibre Channel adapter that connects to a SAN fabric via Fibre Channel or FCoE. The WWPN pool ensures each vHBA gets a unique 64-bit identifier (e.g., 20:00:00:25:b5:00:00:01) for fabric login and zoning. The SAN boot policy specifies the target WWPN and LUN ID (typically LUN 0) so the host's BIOS or UEFI can perform a direct SAN boot without requiring a local disk; this is critical in stateless computing environments where ESXi boots entirely from shared storage.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
