The correct answer is C. redundancy for the management, control, and data planes. Configuring Cisco UCS Fabric Interconnects in cluster mode is a core design for high availability in a UCS domain.
Question
Refer to the exhibit. A network engineer must improve high availability within the given UCS infrastructure. The engineer configured central nodes A and B in cluster mode to ensure that traffic fails over in the case of a network outage. Which type of redundancy will the cluster configuration provide?
Exhibit
Options
- Aredundancy for the management plane only
- Bredundancy via a single fabric interconnect
- Credundancy for the management, control, and data planes
- Dlink-level redundancy via one management port

Why each option
Configuring Cisco UCS Fabric Interconnects in cluster mode is a core design for high availability in a UCS domain.
UCS Fabric Interconnect clustering provides redundancy for more than just the management plane; it extends to the control and data planes as well.
Redundancy via a single fabric interconnect is a contradiction; clustering inherently means using multiple interconnects for redundancy.
When Cisco UCS Fabric Interconnects (FIs) are configured in a cluster, they operate as a redundant pair to provide high availability for the entire UCS domain. This cluster configuration ensures that all critical planes are redundant: the management plane (UCS Manager), the control plane (policies and profiles), and the data plane (server network and storage traffic), allowing for seamless failover in case of a component failure.
UCS Fabric Interconnect clustering provides far more extensive redundancy than just link-level redundancy for a single management port; it ensures high availability for the entire domain's operational and data traffic.
