C. Email traffic
D. Backup traffic
Answer: A. Storage traffic (FCoE or Fibre Channel)
Explanation: Storage traffic is sensitive to latency and requires priority.
What happens if a Fabric Interconnect loses power in a dual-Fabric Interconnect UCS environment?
The other Fabric Interconnect continues to handle all traffic seamlessly
B. The entire UCS environment fails immediately
C. Manual failover is required
D. All servers reboot automatically
Answer: A. The other Fabric Interconnect continues to handle all traffic seamlessly
Explanation: Dual-Fabric Interconnects provide redundancy and failover.
How does UCS Manager use Role-Based Access Control (RBAC)?
To restrict administrative privileges based on user roles
B. To control VLAN memberships
C. To assign IP addresses
D. To manage firmware upgrades
Answer: A. To restrict administrative privileges based on user roles
