300-610 Exam Dumps : Designing Cisco Data Center Infrastructure for Traditional and AI Workloads v1.2 (DCID 300-610)

The reusable Cisco UCS design is to define VLAN membership on vNIC templates and reference those vNIC templates from the service profile templates. Cisco states that a vNIC can be bound to a vNIC template and that UCS Manager then configures the vNIC with the values defined by that template. If a bound vNIC does not match the template, UCS Manager reconfigures it; changes must subsequently be made through the associated template. This creates a single policy location for VLAN selection, fabric choice, MTU, QoS policy references, and related vNIC properties. Binding the vNIC template to the service profile template ensures that every derived service profile receives the same intended LAN configuration. With updating templates, eligible changes can propagate to already-associated profiles in a controlled manner. Defining settings separately in each service profile template duplicates configuration and weakens consistency. Manually attaching uplinks is an infrastructure operation and does not provide reusable server-side VLAN policy. A LAN connectivity policy can group vNIC definitions, but merely declaring VLANs globally does not assign them to the vNICs consumed by the servers. Editing individual server adapters from the Hardware tab defeats policy-based stateless computing and creates configuration drift; a server adapter policy controls adapter behavior rather than VLAN membership. Option C is therefore the only approach that centralizes VLAN intent at the correct UCS abstraction and applies it consistently to all profiles derived from the templates.

RFC 7348 defines Virtual Extensible LAN, so a VXLAN-based overlay is the only option that directly satisfies the stated standards requirement. VXLAN encapsulates Layer 2 Ethernet frames in UDP and transports them across a Layer 3 underlay. Its 24-bit VXLAN Network Identifier provides far greater segmentation scale than the 12-bit VLAN identifier, while the overlay permits workload mobility and logical network extension without requiring the underlay to carry every tenant VLAN. These properties support an active-active application design and preserve network identity when workloads move or recover between locations. The RTO and RPO are operational recovery objectives; VXLAN supplies the network reachability and segmentation foundation, while storage or application replication must maintain the required 15-minute data currency and the recovery orchestration must complete service restoration within four hours. The overlay itself does not replace application-consistent replication or recovery automation. DMVPN provides scalable routed VPN connectivity but is not the RFC 7348 data-center overlay. Geneve is a different encapsulation and does not itself replicate storage data. OTV is a Cisco MAC-in-IP Layer 2 extension technology and can support workload mobility, but it is not the protocol defined by RFC 7348. Therefore, where the question requires an RFC 7348-compliant network design, VXLAN is determinative. Cisco VXLAN EVPN design guide
