That diagnosis is supported by a different symptom: GET requests succeed but the controller rejects POST/PUT site modification. Here the recorded observation is: hTTP401 appears periodically on all API requests after the session expires. The applicable cause is: the client continues sending an expired or invalid authentication token.

That diagnosis is supported by a different symptom: Automation receives a data-plane response instead of a management inventory dataset. Here the recorded observation is: hTTP401 appears periodically on all API requests after the session expires. The applicable cause is: the client continues sending an expired or invalid authentication token.

That diagnosis is supported by a different symptom: A script fails after a UI redesign because it scraped page text rather than a stable API contract. Here the recorded observation is: hTTP401 appears periodically on all API requests after the session expires. The applicable cause is: the client continues sending an expired or invalid authentication token.

That control reduces a separate risk: Read permissions do not imply write authorization for the resource. For the described design, the recurring risk arises from: the client continues sending an expired or invalid authentication token. The specific required safeguard is: use secure token cache/expiry management and avoid printing tokens in diagnostics.

That control reduces a separate risk: The script targets an edge forwarding endpoint instead of the SD-WAN Manager REST API. For the described design, the recurring risk arises from: the client continues sending an expired or invalid authentication token. The specific required safeguard is: use secure token cache/expiry management and avoid printing tokens in diagnostics.

That control reduces a separate risk: The solution relies on browser presentation instead of the supported controller API. For the described design, the recurring risk arises from: the client continues sending an expired or invalid authentication token. The specific required safeguard is: use secure token cache/expiry management and avoid printing tokens in diagnostics.

Using the documented Cisco Catalyst SD-WAN Manager management API for controller inventory operations would not meet the need for an authorized identity and the documented site-changing API with least necessary action grants.

Limiting concurrent API requests and using response-aware retry/backoff rather than blind rapid retries would not meet the need for an authorized identity and the documented site-changing API with least necessary action grants.

Call the documented Catalyst Center REST API with scoped authentication and correct resource paths would not meet the need for an authorized identity and the documented site-changing API with least necessary action grants.

This test measures a different behavior: Inspect authenticated device inventory response and reconcile a known device identifier. It does not establish the target outcome. For the documented fault, the direct acceptance test is: compare successful GET with permitted/forbidden write attempts using scoped test identities.

This test measures a different behavior: Load-test one safe endpoint and inspect controller error/rate-limiting responses. It does not establish the target outcome. For the documented fault, the direct acceptance test is: compare successful GET with permitted/forbidden write attempts using scoped test identities.

This test measures a different behavior: Verify the API returns known edge router inventory and expected management attributes. It does not establish the target outcome. For the documented fault, the direct acceptance test is: compare successful GET with permitted/forbidden write attempts using scoped test identities.

That diagnosis is supported by a different symptom: The controller answers HTTP429 to repeated bursts while the client keeps hammering it. Here the recorded observation is: gET requests succeed but the controller rejects POST/PUT site modification. The applicable cause is: read permissions do not imply write authorization for the resource.

That diagnosis is supported by a different symptom: Automation receives a data-plane response instead of a management inventory dataset. Here the recorded observation is: gET requests succeed but the controller rejects POST/PUT site modification. The applicable cause is: read permissions do not imply write authorization for the resource.

That control reduces a separate risk: Client concurrency/rate handling exceeds permitted API processing limits. For the described design, the recurring risk arises from: read permissions do not imply write authorization for the resource. The specific required safeguard is: check API scope and RBAC before granting broader controller access.

That control reduces a separate risk: The solution relies on browser presentation instead of the supported controller API. For the described design, the recurring risk arises from: read permissions do not imply write authorization for the resource. The specific required safeguard is: check API scope and RBAC before granting broader controller access.

The specific required safeguard is: check API scope and RBAC before granting broader controller access.

Using the documented Cisco Catalyst SD-WAN Manager management API for controller inventory operations would not meet the need for the documented configuration/template API resource and supported modifying HTTP method with the intended payload.

Building the resource URL using the documented current API version and full base path would not meet the need for the documented configuration/template API resource and supported modifying HTTP method with the intended payload.

Implementing the supported API token lifecycle including expiry detection and authorized token refresh would not meet the need for the documented configuration/template API resource and supported modifying HTTP method with the intended payload.

This test measures a different behavior: Compare the requested route with the published API catalog and confirm a valid inventory response. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect resulting policy/template version and actual device deployment state.

This test measures a different behavior: Verify the API returns known edge router inventory and expected management attributes. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect resulting policy/template version and actual device deployment state.

This test measures a different behavior: Observe token renewal and a successful call after the original token's validity window. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect resulting policy/template version and actual device deployment state.

That diagnosis is supported by a different symptom: Automation receives a data-plane response instead of a management inventory dataset. Here the recorded observation is: inventory GET succeeds but no template or edge running configuration changes. The applicable cause is: the called read-only endpoint does not perform a configuration mutation.

That diagnosis is supported by a different symptom: HTTP401 appears periodically on all API requests after the session expires. Here the recorded observation is: inventory GET succeeds but no template or edge running configuration changes. The applicable cause is: the called read-only endpoint does not perform a configuration mutation.

That diagnosis is supported by a different symptom: Previously working inventory collection now returns not found for every device. Here the recorded observation is: inventory GET succeeds but no template or edge running configuration changes. The applicable cause is: the called read-only endpoint does not perform a configuration mutation.

That control reduces a separate risk: The solution relies on browser presentation instead of the supported controller API. For the described design, the recurring risk arises from: the called read-only endpoint does not perform a configuration mutation. The specific required safeguard is: record API intent, method and post-change verification for every automation transaction.

That control reduces a separate risk: The old API route or version was removed or renamed in the controller release. For the described design, the recurring risk arises from: the called read-only endpoint does not perform a configuration mutation. The specific required safeguard is: record API intent, method and post-change verification for every automation transaction.
