NVIDIA NCP-AII Practice Test 33
Question 320
During an NVIDIA AI factory acceptance test, engineers discover: A new storage export grants broad root access while workloads require per-project isolation. Which TWO complementary elements are needed: the correct technical action and the strongest independent diagnostic evidence? Select TWO answers.
- Inspect PDU outlet maps, breaker assignments, dual-cord wiring, load readings and approved failover test logs.
- Inspect NFS or parallel-fs mount options, client ACLs, identity mapping, network routes and file I/O results.
- Mark third-party storage ready as soon as its management address responds to ping, without mounting or reading a file.
- Run supported DCGM health checks and appropriately scoped diagnostics during approved windows, then review failed tests.
- Configure supported storage exports or mounts, client permissions and target networks, then verify real read and write operations.
Explanation
Correct Answers
B:This is the direct operational evidence to investigate: Inspect NFS or parallel-fs mount options, client ACLs, identity mapping, network routes and file I/O results. Observed scenario: A new storage export grants broad root access while workloads require per-project isolation. The governing mechanism is: Storage reachability, export authorization and data-plane I/O performance are separate deployment requirements.
E:This is an appropriate correction for Third-party storage initial network mount: Configure supported storage exports or mounts, client permissions and target networks, then verify real read and write operations. Observed scenario: A new storage export grants broad root access while workloads require per-project isolation. The governing mechanism is: Storage reachability, export authorization and data-plane I/O performance are separate deployment requirements.
Incorrect Answers
A:This alternative is relevant to Dual-feed rack power and PDU mapping but does not directly resolve the current Third-party storage initial network mount issue: Inspect PDU outlet maps, breaker assignments, dual-cord wiring, load readings and approved failover test logs. Observed scenario: A new storage export grants broad root access while workloads require per-project isolation.
C:This tempting but unsafe shortcut is not a sufficient remediation for Third-party storage initial network mount: Mark third-party storage ready as soon as its management address responds to ping, without mounting or reading a file. Observed scenario: A new storage export grants broad root access while workloads require per-project isolation. The governing mechanism is: Storage reachability, export authorization and data-plane I/O performance are separate deployment requirements. The proportionate action is: Configure supported storage exports or mounts, client permissions and target networks, then verify real read and write operations. A direct check is: Inspect NFS or parallel-fs mount options, client ACLs, identity mapping, network routes and file I/O results. The acceptance condition is: Authorized jobs can access the intended datasets with correct permissions and predictable mount recovery.
D:This alternative is relevant to DCGM initial health and diagnostic scope but does not directly resolve the current Third-party storage initial network mount issue: Run supported DCGM health checks and appropriately scoped diagnostics during approved windows, then review failed tests.
