Question 390

The HPE AOS-CX switching case is: A newly added stack member does not inherit correct voice VLAN policy on its copper access ports. Which TWO choices together provide the targeted remedy and independent validation? (Select TWO.)

  1. A switch-peer failure test confirms multichassis LAG membership, gateway operation and stable application reachability.
  2. Connect supported VSF access stacks to appropriate upstream distribution LAGs, STP and routed gateway services without inventing dual-control-plane behavior.
  3. Integrate switch logging, NTP, DNS, authentication and programmatic controls using explicit management VRFs and restrictive service identities.
  4. A member or uplink fault test preserves client traffic and confirms the intended logical LAG and VLAN states.
  5. Integrate switch configuration and monitoring with the intended Central deployment method while reconciling local changes, templates and device exceptions.

Explanation

Correct Answers

B:

The targeted correction for A newly added stack member does not inherit correct voice VLAN policy on its copper access ports is: Connect supported VSF access stacks to appropriate upstream distribution LAGs, STP and routed gateway services without inventing dual-control-plane behavior. It reduces the risk that incompatible aggregation or inconsistent VLAN tagging at a VSF uplink can disconnect an entire logical access stack.

D:

A separate operational validation for A newly added stack member does not inherit correct voice VLAN policy on its copper access ports is: A member or uplink fault test preserves client traffic and confirms the intended logical LAG and VLAN states. It proves intended behavior instead of accepting configuration presence alone.

Incorrect Answers

A:

This alternative concerns vsx multi-chassis lag and network service integration; its associated risk is: An upstream device attached to two independent unmanaged peers cannot safely treat them as one LACP aggregation partner. The observed case A newly added stack member does not inherit correct voice VLAN policy on its copper access ports requires the more specific vsf stack and access integration to upstream distribution control. The targeted action is: Connect supported VSF access stacks to appropriate upstream distribution LAGs, STP and routed gateway services without inventing dual-control-plane behavior.

C:

This alternative concerns aos-cx integration with monitoring aaa and automation services; its associated risk is: Misrouted management traffic or excessive API privileges can hide outages and grant unintended configuration access. The observed case A newly added stack member does not inherit correct voice VLAN policy on its copper access ports requires the more specific vsf stack and access integration to upstream distribution control. The targeted action is: Connect supported VSF access stacks to appropriate upstream distribution LAGs, STP and routed gateway services without inventing dual-control-plane behavior.

E:

This alternative concerns central and aos-cx configuration consistency; its associated risk is: A local fix that conflicts with centrally enforced state can disappear on the next synchronization cycle. The observed case A newly added stack member does not inherit correct voice VLAN policy on its copper access ports requires the more specific vsf stack and access integration to upstream distribution control. The targeted action is: Connect supported VSF access stacks to appropriate upstream distribution LAGs, STP and routed gateway services without inventing dual-control-plane behavior.

Question 391

An HPE Aruba Networking engineer observes: A distribution switch observes unexpected LACP partner identifiers after the access devices are rebuilt as one VSF stack. The corrective solution must keep intended connectivity, segmentation, and operational resilience. Which response best satisfies the technical requirement without disrupting unrelated traffic?

  1. Connect supported VSF access stacks to appropriate upstream distribution LAGs, STP and routed gateway services without inventing dual-control-plane behavior.
  2. Integrate switch logging, NTP, DNS, authentication and programmatic controls using explicit management VRFs and restrictive service identities.
  3. Use supported VSX LAG across two peers with coordinated ISL, keepalive, VLAN and active-gateway settings when dual-homed connectivity is required.
  4. Integrate switch configuration and monitoring with the intended Central deployment method while reconciling local changes, templates and device exceptions.

Explanation

Correct Answer

A:

The decisive observed condition is: A distribution switch observes unexpected LACP partner identifiers after the access devices are rebuilt as one VSF stack. The appropriate switching action is: Connect supported VSF access stacks to appropriate upstream distribution LAGs, STP and routed gateway services without inventing dual-control-plane behavior.

Question 392

The switch operations team reports: A distribution switch observes unexpected LACP partner identifiers after the access devices are rebuilt as one VSF stack. Which failure or service risk most directly follows from leaving this condition uncorrected?

  1. Misrouted management traffic or excessive API privileges can hide outages and grant unintended configuration access.
  2. A local fix that conflicts with centrally enforced state can disappear on the next synchronization cycle.
  3. Incompatible aggregation or inconsistent VLAN tagging at a VSF uplink can disconnect an entire logical access stack.
  4. An upstream device attached to two independent unmanaged peers cannot safely treat them as one LACP aggregation partner.

Explanation

Correct Answer

C:

The direct operational failure mode is: Incompatible aggregation or inconsistent VLAN tagging at a VSF uplink can disconnect an entire logical access stack. It applies to the condition A distribution switch observes unexpected LACP partner identifiers after the access devices are rebuilt as one VSF stack. The suitable corrective action is: Connect supported VSF access stacks to appropriate upstream distribution LAGs, STP and routed gateway services without inventing dual-control-plane behavior.

Question 393

An HPE Aruba Networking engineer observes: A virtualization cluster bonds two server NICs across a VSX pair but the peer LAG IDs do not match.

Question 394

An engineer investigates: A virtualization cluster bonds two server NICs across a VSX pair but the peer LAG IDs do not match. Which test would independently confirm expected switch behavior?

  1. A member or uplink fault test preserves client traffic and confirms the intended logical LAG and VLAN states.
  2. End-to-end service checks prove correct syslog delivery, time, AAA fallback and authorized automation from the selected VRF.
  3. A switch-peer failure test confirms multichassis LAG membership, gateway operation and stable application reachability.
  4. A controlled policy change remains effective after Central reconciliation and matches its intended device group and exceptions.

Explanation

Correct Answer

C:

The independent acceptance evidence for A virtualization cluster bonds two server NICs across a VSX pair but the peer LAG IDs do not match is: A switch-peer failure test confirms multichassis LAG membership, gateway operation and stable application reachability. It tests whether the team has actually implemented: Use supported VSX LAG across two peers with coordinated ISL, keepalive, VLAN and active-gateway settings when dual-homed connectivity is required. An enabled interface or saved configuration by itself is not evidence of complete service recovery.
