Designing Cisco Data Center Infrastructure (DCID) — Question 130

A network administrator must create a redundant vHBA for the mission-critical virtual machines (VMs) installed on a Cisco UCS Fabric Interconnect blade server. The VMs access multiple datastores using VSAN55 and VSAN95. The datastore on which the VMs are hosted must be accessible if any of the uplinks goes offline. Which action meets these requirements?

Answer options

• A. Attach VSAN55 to vHBA1 and VSAN95 to vHBA2.
• B. Assign VSAN55 and VSAN95 to vHBA1 and vHBA2.
• C. Enable failover for the vHBA with VSAN55 and VSAN95 enabled.
• D. Configure load-balancing for vHBAs with VSAN55 and VSAN95 attached.

Correct answer: A

Explanation

The correct answer is A because attaching VSAN55 to vHBA1 and VSAN95 to vHBA2 provides redundancy, ensuring that if one uplink goes down, the other vHBA can still access its corresponding VSAN. Option B is incorrect as assigning both VSANs to the same vHBAs does not create redundancy. Option C, while it relates to failover, does not specifically address the need for separate vHBAs for each VSAN. Option D focuses on load-balancing, which does not meet the requirement for redundancy.
