Question 740

The HPE AOS-CX switching case is: A planned VSF ring becomes a line after a cable failure but no alert distinguishes its degraded resilience. Select TWO: a corrective switching action and separate evidence that the correction worked. (Select TWO.)

  1. Review AAA login, 802.1X denials, role changes and management access logs for abnormal patterns with privacy-aware escalation.
  2. Monitor VSF conductor, member presence, ring or chain status and per-member uplinks to recognize degraded access availability.
  3. A stack event test alerts on lost member or link and confirms all expected ports return after recovery.
  4. Interpret VSX peer, inter-switch link, keepalive, synchronization and multichassis LAG indicators together instead of relying on one peer's health.
  5. Before/after trend data uses consistent time windows and shows whether measured user impact and relevant network counters improved.

Explanation

Correct Answers

B:

The targeted correction for A planned VSF ring becomes a line after a cable failure but no alert distinguishes its degraded resilience is: Monitor VSF conductor, member presence, ring or chain status and per-member uplinks to recognize degraded access availability. It reduces the risk that a surviving logical stack address can conceal a missing member and hundreds of failed physical user ports.

C:

A separate operational validation for A planned VSF ring becomes a line after a cable failure but no alert distinguishes its degraded resilience is: A stack event test alerts on lost member or link and confirms all expected ports return after recovery. It proves intended behavior instead of accepting configuration presence alone.

Incorrect Answers

A:

This alternative concerns security event and unauthorized management detection; its associated risk is: A successful user session or high denial count alone cannot establish legitimacy or rule out an attack without correlation. The observed case A planned VSF ring becomes a line after a cable failure but no alert distinguishes its degraded resilience requires the more specific vsf member and stack topology observability control. The targeted action is: Monitor VSF conductor, member presence, ring or chain status and per-member uplinks to recognize degraded access availability.

D:

This alternative concerns vsx pair health and isl keepalive dashboard; its associated risk is: An apparently healthy primary switch can hide a degraded secondary path that will fail under maintenance. The observed case A planned VSF ring becomes a line after a cable failure but no alert distinguishes its degraded resilience requires the more specific vsf member and stack topology observability control. The targeted action is: Monitor VSF conductor, member presence, ring or chain status and per-member uplinks to recognize degraded access availability.

E:

This alternative concerns network health dashboards and time-series baseline; its associated risk is: An average bandwidth graph can conceal short congestion bursts and misleading seasonal comparisons. The observed case A planned VSF ring becomes a line after a cable failure but no alert distinguishes its degraded resilience requires the more specific vsf member and stack topology observability control. The targeted action is: Monitor VSF conductor, member presence, ring or chain status and per-member uplinks to recognize degraded access availability.

Question 741

An HPE Aruba Networking engineer observes: A new member boots with mismatched software and does not join the approved stack. The corrective solution must keep intended connectivity, segmentation, and operational resilience. Which implementation or troubleshooting step directly resolves the specific network issue?

  1. Compare current AOS-CX telemetry against a known healthy baseline and traffic time window rather than drawing conclusions from isolated graphs.
  2. Interpret OSPF/BGP neighbor states, selected route prefixes and next-hop changes before troubleshooting downstream application latency.
  3. Interpret interface administrative and operational state, negotiated speed, error counters and trend direction in context before taking action.
  4. Monitor VSF conductor, member presence, ring or chain status and per-member uplinks to recognize degraded access availability.

Explanation

Correct Answer

D:

The decisive observed condition is: A new member boots with mismatched software and does not join the approved stack. The appropriate switching action is: Monitor VSF conductor, member presence, ring or chain status and per-member uplinks to recognize degraded access availability. It addresses the risk that a surviving logical stack address can conceal a missing member and hundreds of failed physical user ports. Confirm with: A stack event test alerts on lost member or link and confirms all expected ports return after recovery.

B:

This alternative concerns route-table neighbor and path change monitoring; its associated risk is: A session-up metric alone can hide missing or rejected prefixes, and route churn can cause sporadic traffic loss. The observed case A new member boots with mismatched software and does not join the approved stack requires the more specific vsf member and stack topology observability control. The targeted action is: Monitor VSF conductor, member presence, ring or chain status and per-member uplinks to recognize degraded access availability.

C:

This alternative concerns switch interface telemetry and threshold interpretation; its associated risk is: A single green link status can conceal elevated errors, mismatched speed or an emerging optical failure. The observed case A new member boots with mismatched software and does not join the approved stack requires the more specific vsf member and stack topology observability control. The targeted action is: Monitor VSF conductor, member presence, ring or chain status and per-member uplinks to recognize degraded access availability.

Question 742

An engineer investigates: A new member boots with mismatched software and does not join the approved stack. What acceptance evidence most directly demonstrates the correction succeeded?

  1. A measured trend and cross-check distinguish an actionable fault from normal transient changes and verify remediation.
  2. A stack event test alerts on lost member or link and confirms all expected ports return after recovery.
  3. Before/after trend data uses consistent time windows and shows whether measured user impact and relevant network counters improved.
  4. A route-health trial ties expected adjacencies and advertised/received prefixes to successful bidirectional probes.

Explanation

Correct Answer

B:

The independent acceptance evidence for A new member boots with mismatched software and does not join the approved stack is: A stack event test alerts on lost member or link and confirms all expected ports return after recovery.
