300-610 Question #188: Real Exam Question with Answer & Explanation
The correct answer is A. end host mode D. N-Port lD virtualization. To connect Cisco UCS to an existing SAN without exhausting domain IDs and to direct SAN traffic to specific fabric interconnect ports, end host mode and N-Port ID Virtualization (NPIV) must be deployed.
Storage Network Design
Question
A network engineer is using a Cisco UCS environment connected to a Fibre Channel storage array. The Cisco UCS environment must be connected to an existing SAN network, and several Cisco MDS 9000 Series Switches must be added to increase storage density. The solution must not exhaust the SAN network from the list of available domain IDs after connecting Also, most of the SAN traffic must be mapped from the Cisco UCS blades to a specific group of the fabric interconnect ports. Which two features must be deployed to meet these requirements? (Choose two.)
Options
- Aend host mode
- Bstatic PIN grouping
- Cpriority flow control
- DN-Port lD virtualization
- Edynamic port pinning
Explanation
To connect Cisco UCS to an existing SAN without exhausting domain IDs and to direct SAN traffic to specific fabric interconnect ports, end host mode and N-Port ID Virtualization (NPIV) must be deployed.
Common mistakes.
- B. Static PIN grouping in UCS maps a vHBA to a specific uplink Fibre Channel port and helps in traffic steering, but it does not address the domain ID exhaustion issue.
- C. Priority Flow Control (PFC) is a Data Center Bridging (DCB) standard used in FCoE environments to prevent frame loss for specific traffic classes and is not directly related to connecting UCS to an existing Fibre Channel SAN or addressing domain ID exhaustion.
- E. Dynamic port pinning maps vHBAs to available uplink Fibre Channel ports dynamically, which is good for load balancing but does not solve the domain ID exhaustion problem or provide the specific traffic mapping required.
Concept tested. Cisco UCS Fibre Channel SAN integration (End Host Mode, NPIV)
