350-601 Compute Practice Question
A network engineer is configuring a UCS service profile for a B-series blade server. The goal is to allow the blade to be replaced without requiring reconfiguration of network identities. Which UCS feature enables this capability?
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
✓
Stateless computing via service profile
Stateless computing abstracts hardware identities such as MAC addresses and WWNNs into the service profile, so a replacement blade inherits the same identities.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Fabric Interconnect failover
Why it's wrong here
Fabric Interconnect failover provides redundancy for the network fabric, not hardware abstraction for blade replacement.
- ✓
Stateless computing via service profile
Why this is correct
Correct. Stateless computing decouples the OS from hardware, allowing blade replacement without reconfiguration.
- ✗
CIMC out-of-band management
Why it's wrong here
CIMC is for remote management of rack servers, not for blade hardware abstraction.
- ✗
UCS Central global policies
Why it's wrong here
UCS Central manages multiple domains but does not directly enable stateless computing on a single blade.
