Question 790
The HPE AOS-CX switching case is: A programmer uses a broad device selection that includes production core switches during a lab change. Which TWO choices together provide the targeted remedy and independent validation? (Select TWO.)
Explanation
Correct Answers
The targeted correction for A programmer uses a broad device selection that includes production core switches during a lab change is: Apply reviewed automation templates with source control, per-device variables, idempotent behavior and pre/post checks for AOS-CX switches. It reduces the risk that a generic script applied without device variables or dry-run can overwrite management addresses and disrupt multiple sites at once.
A separate operational validation for A programmer uses a broad device selection that includes production core switches during a lab change is: Repeated automation runs preserve the intended state and a change diff shows only approved updates on the selected devices. It proves intended behavior instead of accepting configuration presence alone.
Incorrect Answers
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 A programmer uses a broad device selection that includes production core switches during a lab change requires the more specific ansible and programmatic configuration-change control control. The targeted action is: Apply reviewed automation templates with source control, per-device variables, idempotent behavior and pre/post checks for AOS-CX switches.
This alternative concerns safe firmware release and feature compatibility planning; its associated risk is: Upgrading incompatible software across peer switches can create avoidable outages and leave routing or stacking features unavailable. The observed case A programmer uses a broad device selection that includes production core switches during a lab change requires the more specific ansible and programmatic configuration-change control control. The targeted action is: Apply reviewed automation templates with source control, per-device variables, idempotent behavior and pre/post checks for AOS-CX switches.
This alternative concerns aos-cx rest api credential and read-only inventory audit; its associated risk is: An overprivileged automation account or unsupported endpoint can disclose configuration or modify production state without intended approval. The observed case A programmer uses a broad device selection that includes production core switches during a lab change requires the more specific ansible and programmatic configuration-change control control. The targeted action is: Apply reviewed automation templates with source control, per-device variables, idempotent behavior and pre/post checks for AOS-CX switches.
