VRF-Lite provides the required Layer 3 separation by creating independent routing and forwarding instances on R1. Cisco documents that each VRF maintains its own IPv4 and IPv6 routing tables and makes routing decisions independently. Interfaces facing Department A and Department B are assigned to their respective VRFs, so a route learned or configured in one department is not automatically available to the other. The Department B VRF can contain a single default route with next hop 192.168.20.1, forcing its external traffic toward ISP-2. Department A can retain its existing routing policy and ISP reachability without exposing those paths to Department B. An MPLS VPN is unnecessary because the requirement concerns local virtualization on one router, not a provider MPLS backbone. Separate VLANs create Layer 2 broadcast-domain separation, but an ACL tied only to ISP-1 does not provide the clean, independent routing contexts required and can become difficult to maintain as routes change. Running separate routing protocols in the same global routing table also fails to guarantee isolation because installed routes still enter a common RIB and FIB unless VRFs are used. VRF-Lite therefore supplies both deterministic ISP selection and structural separation. Any intentional communication between departments would require explicit route leaking or an external policy-controlled service, preserving the default isolation specified in the design.

A logical-configuration backup is the most targeted choice because Cisco UCS classifies service profiles as logical configuration objects. Cisco states that this XML backup includes service profiles together with related logical constructs such as VLANs, VSANs, pools, policies, and templates. It can be imported into the original fabric interconnect, allowing the administrator to recover the deleted profiles through a configuration import instead of restoring the entire UCS domain. The import should still be reviewed carefully: dependencies referenced by a service profile must exist or be included, and changes to an interface associated with a server can be disruptive. This makes a maintenance window and a preview of the import changes prudent.

Option A is broader than necessary. An all-configuration backup contains both system and logical settings, so it could contain the profiles, but it is not the most specific backup for this requirement. Option C is incorrect because a system-configuration backup contains administrative and global settings such as local users, roles, and locales; it does not target service profiles. Option D is intended for full-state disaster recovery. A full-state backup is a binary snapshot used to restore the complete UCS Manager domain and is inappropriate when only three logical objects must be recovered without disturbing unrelated fabric configuration. Therefore, importing the relevant logical-configuration backup provides the narrowest recovery scope and best aligns with the stated rollback objective.
