To help automate the vHBA configuration process, a network engineer is configuring vHBA template pairs on UCS. The engineer is creating primary and secondary templates to define how vHBAs on a server

The correct answer is B. The WWPN pool configuration will not be shared between the two templates. When configuring vHBA template pairs on Cisco UCS, the WWPN pool configuration is not shared between the primary and secondary templates.

Question

To help automate the vHBA configuration process, a network engineer is configuring vHBA template pairs on UCS. The engineer is creating primary and secondary templates to define how vHBAs on a server connect to the SAN. Which fact about the template pair should the engineer consider for its potential impact on service?

Options

  • AThe fabric ID configuration will be shared between the two templates
  • BThe WWPN pool configuration will not be shared between the two templates
  • CThe QoS policy configuration will not be shared between the two templates
  • DThe description configuration will be shared between the two templates

Why each option

When configuring vHBA template pairs on Cisco UCS, the WWPN pool configuration is not shared between the primary and secondary templates.

AThe fabric ID configuration will be shared between the two templates

Fabric ID is a property of the Fabric Interconnect, not a configuration shared between vHBA templates.

BThe WWPN pool configuration will not be shared between the two templatesCorrect

When creating vHBA template pairs in Cisco UCS, each vHBA requires a unique World Wide Port Name (WWPN) for proper SAN functionality and path redundancy. Therefore, the WWPN pool configuration is explicitly not shared between the two templates, ensuring each template draws WWPNs from a different, dedicated WWPN pool for unique addressing.

CThe QoS policy configuration will not be shared between the two templates

QoS policies can be configured independently or shared between vHBA templates depending on the desired traffic management strategy for the respective vHBAs.

DThe description configuration will be shared between the two templates

The description field is metadata and can be set independently for each template within the pair, and sharing it would have no technical impact on service.
