Question 540
During an industrial computer-vision rollout at a manufacturing operator, engineers report the following issue: A host-level firewall is the only control even though tenants have root access. The affected work supports factory cameras and maintenance analytics; downtime and incorrect detections can interrupt production. Select TWO: the most appropriate action and the strongest verification of that action. (Select TWO.)
Explanation
Correct Answers
Correct corrective action. Use supported DPU infrastructure functions to separate privileged platform networking or security services from untrusted host workload control when appropriate. This fits the specific reported issue: A host-level firewall is the only control even though tenants have root access. The corresponding failure being reduced is: Allowing an untrusted tenant host full control of shared infrastructure services can undermine isolation and incident containment.
Correct independent evidence. An authorization test demonstrates that tenant workloads cannot modify privileged DPU-managed policy while permitted infrastructure traffic continues. This verifies the corrective approach for the affected factory cameras and maintenance analytics instead of treating an architecture diagram alone as success.
Incorrect Answers
Not the most direct the action-and-evidence pair for these facts. The selected placement demonstrably meets allowed data locations, access controls, connectivity and realistic transfer times. This choice concerns data locality and control in ai deployment placement and may be valid in another design. But this case reports 'A host-level firewall is the only control even though tenants have root access', which calls for reasoning about dpu isolation and secure infrastructure services. The targeted response is: Use supported DPU infrastructure functions to separate privileged platform networking or security services from untrusted host workload control when appropriate.
Not the most direct the action-and-evidence pair for these facts. Associate a BlueField DPU with offloading selected networking, storage and security infrastructure work from host CPUs while meeting supported deployment constraints. This choice concerns bluefield dpu infrastructure offload and may be valid in another design. But this case reports 'A host-level firewall is the only control even though tenants have root access', which calls for reasoning about dpu isolation and secure infrastructure services. The targeted response is: Use supported DPU infrastructure functions to separate privileged platform networking or security services from untrusted host workload control when appropriate.
Not the most direct the action-and-evidence pair for these facts. Plan Ethernet-based RDMA such as RoCE with appropriate traffic engineering and congestion behavior rather than assuming a generic best-effort Ethernet configuration is sufficient. This choice concerns roce congestion and loss-management considerations and may be valid in another design. But this case reports 'A host-level firewall is the only control even though tenants have root access', which calls for reasoning about dpu isolation and secure infrastructure services. The targeted response is: Use supported DPU infrastructure functions to separate privileged platform networking or security services from untrusted host workload control when appropriate.
