A Cisco engineer is preparing a service profile template for a design, which consists of 20 x UCS B200M6 blade servers, 2 x UCS 6454 Fabric Interconnect in End Host Mode, and 3 x UCS 5108 server chass
The correct answer is D. round robin. When a UCS service profile template is configured without a vNIC/vHBA placement policy for blade servers with VIC adapters, the system defaults to assigning vCons in a round robin fashion.
Question
A Cisco engineer is preparing a service profile template for a design, which consists of 20 x UCS B200M6 blade servers, 2 x UCS 6454 Fabric Interconnect in End Host Mode, and 3 x UCS 5108 server chassis with 2408 Fabric Extenders. The blade servers are equipped with VIC 1480 adapters. The engineer does not configure a vNIC/vHBA placement policy in the service profile and the vNICs and vHBAs are assigned to the vCon in a particular order. What is the mapping scheme in which Cisco UCS assigns the vCons based on the type of server and the selected virtual slot?
Options
- Alinear ordered
- Bnetwork mesh
- Ccross match
- Dround robin

Why each option
When a UCS service profile template is configured without a vNIC/vHBA placement policy for blade servers with VIC adapters, the system defaults to assigning vCons in a round robin fashion.
Linear ordered assignment would imply a sequential allocation which is not the default behavior when no explicit policy is set.
Network mesh refers to a network topology, not a vCon assignment strategy in UCS.
Cross match is not a recognized vCon placement policy or default mapping scheme in Cisco UCS.
In Cisco UCS, when no vNIC/vHBA placement policy is explicitly configured in a service profile for blade servers equipped with VIC adapters, the system by default employs a round robin mapping scheme. This method ensures that vNICs and vHBAs are evenly distributed across the available virtual controllers (vCons) to achieve load balancing and redundancy.
