200-155 · Question #211

Refer to the exhibit. Which benefit of a vHBA template pair is true?

The correct answer is D. provides redundancy by linking to another template that uses fabric B. A vHBA template pair simplifies configuration and ensures redundancy for server access to storage by linking two vHBAs, one for each Fibre Channel fabric.

Why each option

A vHBA template pair simplifies configuration and ensures redundancy for server access to storage by linking two vHBAs, one for each Fibre Channel fabric.

Arequires that you configure vHBA pairs independently

A vHBA template pair is designed to simplify and standardize configuration by treating two vHBAs as a logical unit, not to require them to be configured independently.

Ballows the use of fewer IP addresses in the WWPN pool

vHBAs use World Wide Port Names (WWPNs) for identification in Fibre Channel networks, not IP addresses, and a template pair does not inherently reduce the number of WWPNs used, but rather simplifies their consistent assignment.

Cenables you to group vHBAs that share attributes

While a vHBA template pair does group vHBAs, its specific 'pair' benefit is primarily for providing redundancy across two distinct fabrics (e.g., Fabric A and Fabric B), rather than just grouping based on shared attributes.

Dprovides redundancy by linking to another template that uses fabric BCorrect

A vHBA template pair inherently provides redundancy by linking two virtual HBAs (vHBAs) together, with one vHBA typically assigned to Fabric A and the other to Fabric B. This design ensures high availability for Fibre Channel storage connectivity, as a failure in one fabric path allows the server to continue accessing storage through the other.
