Which TWO complementary elements are needed: the correct technical action and the strongest independent diagnostic evidence? Select TWO answers.
- Assume every Redfish response describes all installed hardware and that inventory queries cannot affect a powered node.
- Use approved authenticated BMC inventory endpoints, distinguish read-only calls from power actions and corroborate returned component state.
- Compare BMC-reported component inventory, nvfwupd version reports, device revisions and release support notes.
- Calculate peak supported server and fabric load, apply facility margin and verify branch and PDU capacity under representative load.
- Inspect management API target paths, access scopes, sensor values, chassis actions and independent host inventory.
Explanation
Correct Answers
B:This is an appropriate correction for Redfish inventory and IPMI management boundaries: Use approved authenticated BMC inventory endpoints, distinguish read-only calls from power actions and corroborate returned component state. Observed scenario: A technician executes an IPMI power-cycle action against a production node while only collecting inventory was authorized. The governing mechanism is: Redfish and IPMI expose hardware management data and operations, but endpoint selection and privileges determine their safety.
E:This is the direct operational evidence to investigate: Inspect management API target paths, access scopes, sensor values, chassis actions and independent host inventory. Observed scenario: A technician executes an IPMI power-cycle action against a production node while only collecting inventory was authorized.
