350-601 Compute Practice Question
An engineer is configuring PXE boot for a UCS B-series blade. The blade's vNIC is associated with a VLAN that has no IP helper address configured. What is required to allow the blade to obtain an IP address from a DHCP server on a different subnet?
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
✓
Add an IP helper address on the VLAN interface in the upstream switch
PXE boot requires DHCP. Without IP helper, broadcast DHCP requests cannot cross subnets. A DHCP relay or IP helper is needed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure a static IP address in the service profile
Why it's wrong here
PXE boot typically uses DHCP; static IP may not work with PXE.
- ✗
Enable DHCP snooping on the Fabric Interconnect
Why it's wrong here
DHCP snooping is security feature, not relay.
- ✓
Add an IP helper address on the VLAN interface in the upstream switch
Why this is correct
IP helper relays DHCP broadcasts to the DHCP server.
- ✗
Use a local DHCP server on the same VLAN
Why it's wrong here
Could work but not always feasible; IP helper is typical.
