QuestionQ10

Troubleshoot

Map the Data Plane Impact when Pensando Policy and Services Manager (PSM) is deployed in high availability (HA) and an HA issue occurs.

Drag & Drop
One PSM node fails or becomes unreachable.
The management plane is down between a DSS and the PSM.
Two PSM nodes fail or become unreachable.
Explanation

PSM HA has three PSM VMs, so losing one preserves quorum and configuration updates continue. A DSS that cannot reach the PSM cannot receive configuration changes, although existing stateful data-plane services continue. Losing two PSM nodes removes quorum; the PSM prevents logins and configuration changes to avoid split brain, while existing stateful services remain unaffected.

QuestionQ33

Troubleshoot

Map the management-plane impact when Pensando Policy and Services Manager (PSM) is deployed in high availability (HA) and an HA issue occurs.

Drag & Drop
Configuration changes are accepted by the PSM and applied to DSSes Metrics and logs are regularly collected.
Configuration changes are accepted by the PSM but will not take effect until the DSS and PSM can communicate. Metrics and logs will be buffered at the DSS as local memory availability permits.
The PSM does not allow new user logins and does not accept configuration changes, to avoid a “split-brain” scenario. Metrics and logs are not collected by the PSM but will be buffered at the DSS subject to local storage availability.
Explanation

A single PSM-node failure retains HA-cluster quorum, so configuration delivery and telemetry collection continue. A DSS-to-PSM communication outage delays delivery to that DSS and causes it to buffer telemetry locally. Failure of two PSM nodes removes quorum; PSM prevents new logins and configuration changes to avoid split brain, while DSSs buffer telemetry subject to local storage capacity.

QuestionQ63

Troubleshoot

Interface 1/2/1 has an intermittent connectivity failure. You run the diag cable-diagnostic test 1/2/1 command to identify possible issues with the cable connected to the port. Match each diagnostic result to the description that helps identify the cable issue.

Drag & Drop
cable test inconclusive
no cable faults found
pair is not terminated with a link partner
short circuit with another wire pair
short circuit within the same wire pair
Explanation

Cable diagnostics report an open when a twisted pair lacks a terminating link partner, an intra-short when the two conductors of one pair are shorted, and an inter-short when conductors from different pairs are shorted. A good result indicates no cable fault; unknown means the test could not determine a conclusive result.
