Question 780

The HPE AOS-CX switching case is: An API inventory job receives an authentication error but reports every switch as successfully audited. Select TWO: a corrective switching action and separate evidence that the correction worked. (Select TWO.)

  1. Use documented authenticated AOS-CX REST API operations with appropriately scoped credentials and supported endpoints to collect configuration and health data.
  2. Verify that approved configuration was saved to startup, back up the previous state and test recovery before restarting a switch.
  3. Repeated automation runs preserve the intended state and a change diff shows only approved updates on the selected devices.
  4. Audit switches through documented APIs or supported automation with signed inventory, configuration diff, security findings and repeatable recovery records.
  5. An authorized inventory request returns expected data while unauthorized writes and malformed inputs are denied and logged.

Explanation

Correct Answers

A:

The targeted correction for An API inventory job receives an authentication error but reports every switch as successfully audited is: Use documented authenticated AOS-CX REST API operations with appropriately scoped credentials and supported endpoints to collect configuration and health data. It reduces the risk that an overprivileged automation account or unsupported endpoint can disclose configuration or modify production state without intended approval.

E:

A separate operational validation for An API inventory job receives an authentication error but reports every switch as successfully audited is: An authorized inventory request returns expected data while unauthorized writes and malformed inputs are denied and logged. It proves intended behavior instead of accepting configuration presence alone.

Incorrect Answers

B:

This alternative concerns config restore and startup persistence protection; its associated risk is: An unsaved edit disappears on reboot while a mistakenly persisted temporary setting survives beyond its intended scope. The observed case An API inventory job receives an authentication error but reports every switch as successfully audited requires the more specific aos-cx rest api credential and read-only inventory audit control. The targeted action is: Use documented authenticated AOS-CX REST API operations with appropriately scoped credentials and supported endpoints to collect configuration and health data.

C:

This alternative concerns ansible and programmatic configuration-change control; its associated risk is: A generic script applied without device variables or dry-run can overwrite management addresses and disrupt multiple sites at once. The observed case An API inventory job receives an authentication error but reports every switch as successfully audited requires the more specific aos-cx rest api credential and read-only inventory audit control. The targeted action is: Use documented authenticated AOS-CX REST API operations with appropriately scoped credentials and supported endpoints to collect configuration and health data.

D:

This alternative concerns programmatic compliance telemetry and rollback evidence; its associated risk is: Collecting data without correlating device identity or verifying effects can create false compliance reports and unsafe mass changes. The observed case An API inventory job receives an authentication error but reports every switch as successfully audited requires the more specific aos-cx rest api credential and read-only inventory audit control. The targeted action is: Use documented authenticated AOS-CX REST API operations with appropriately scoped credentials and supported endpoints to collect configuration and health data.

Question 781

An HPE Aruba Networking engineer observes: A read-only network discovery task is implemented using unrestricted device configuration rights.

Question 782

An engineer investigates: A read-only network discovery task is implemented using unrestricted device configuration rights. Which test would independently confirm expected switch behavior?

  1. An isolated test site restores console or OOB management and rolls back a failed uplink change without physical improvisation.
  2. An authorized inventory request returns expected data while unauthorized writes and malformed inputs are denied and logged.
  3. Repeated automation runs preserve the intended state and a change diff shows only approved updates on the selected devices.
  4. A reproducible audit detects seeded drift, records source identity and confirms recovery after an approved remediation.

Explanation

Correct Answer

B:

The independent acceptance evidence for A read-only network discovery task is implemented using unrestricted device configuration rights is: An authorized inventory request returns expected data while unauthorized writes and malformed inputs are denied and logged.
