Question 230

The HPE AOS-CX switching case is: An overbroad trunk carries a guest VLAN onto a restricted server aggregation path. Which TWO choices together provide the targeted remedy and independent validation? (Select TWO.)

  1. Configure and validate tagged VLAN membership across each uplink and consistent native VLAN treatment where required by the topology.
  2. A hop-by-hop tag trace proves required VLANs pass and disallowed VLANs are absent on all uplinks.
  3. Assign user ports to the intended access VLAN and verify that untagged frames reach the proper broadcast domain.
  4. The operational LACP partner and member states agree and a controlled link-failure and multi-flow throughput test passes.
  5. Set a consistent MSTP region name, revision and VLAN-to-instance mapping and deliberately place the root where the topology requires.

Explanation

Correct Answers

A:

The targeted correction for An overbroad trunk carries a guest VLAN onto a restricted server aggregation path is: Configure and validate tagged VLAN membership across each uplink and consistent native VLAN treatment where required by the topology. It reduces the risk that a missing tagged VLAN on one hop silently isolates clients, while unintended VLAN allowance bridges security domains.

B:

A separate operational validation for An overbroad trunk carries a guest VLAN onto a restricted server aggregation path is: A hop-by-hop tag trace proves required VLANs pass and disallowed VLANs are absent on all uplinks. It proves intended behavior instead of accepting configuration presence alone.

Incorrect Answers

C:

This alternative concerns vlan access port membership and untagged traffic; its associated risk is: A correct IP address cannot repair wrong VLAN membership, and access ports in unintended VLANs can expose protected resources. The observed case An overbroad trunk carries a guest VLAN onto a restricted server aggregation path requires the more specific vlan trunk tagging and permitted vlan filters control. The targeted action is: Configure and validate tagged VLAN membership across each uplink and consistent native VLAN treatment where required by the topology.

D:

This alternative concerns lacp member selection and load distribution; its associated risk is: A partially formed aggregation can strand traffic or produce surprising throughput because a single flow usually hashes to one member. The observed case An overbroad trunk carries a guest VLAN onto a restricted server aggregation path requires the more specific vlan trunk tagging and permitted vlan filters control. The targeted action is: Configure and validate tagged VLAN membership across each uplink and consistent native VLAN treatment where required by the topology.

E:

This alternative concerns mstp configuration and loop control; its associated risk is: A mismatched MSTP region or unintended root can block critical trunks or increase convergence disruption. The observed case An overbroad trunk carries a guest VLAN onto a restricted server aggregation path requires the more specific vlan trunk tagging and permitted vlan filters control. The targeted action is: Configure and validate tagged VLAN membership across each uplink and consistent native VLAN treatment where required by the topology.

Question 231

An HPE Aruba Networking engineer observes: A migration changes an access VLAN but forgets to update the downstream trunk permit list. The corrective solution must keep intended connectivity, segmentation, and operational resilience. Which response best satisfies the technical requirement without disrupting unrelated traffic?

  1. Set a consistent MSTP region name, revision and VLAN-to-instance mapping and deliberately place the root where the topology requires.
  2. Build a supported VSF stack with a defined conductor, member identities and split-detection design while validating management and data forwarding.
  3. Assign user ports to the intended access VLAN and verify that untagged frames reach the proper broadcast domain.
  4. Configure and validate tagged VLAN membership across each uplink and consistent native VLAN treatment where required by the topology.

Explanation

The observed case A migration changes an access VLAN but forgets to update the downstream trunk permit list requires the more specific vlan trunk tagging and permitted vlan filters control. The targeted action is: Configure and validate tagged VLAN membership across each uplink and consistent native VLAN treatment where required by the topology.

Question 232

The switch operations team reports: A migration changes an access VLAN but forgets to update the downstream trunk permit list. Which failure or service risk most directly follows from leaving this condition uncorrected?

  1. A mismatched MSTP region or unintended root can block critical trunks or increase convergence disruption.
  2. Incorrect member order or split handling can leave orphaned interfaces and interrupt a shared access stack.
  3. A missing tagged VLAN on one hop silently isolates clients, while unintended VLAN allowance bridges security domains.
  4. A correct IP address cannot repair wrong VLAN membership, and access ports in unintended VLANs can expose protected resources.

Explanation

Correct Answer

C:

The direct operational failure mode is: A missing tagged VLAN on one hop silently isolates clients, while unintended VLAN allowance bridges security domains. It applies to the condition A migration changes an access VLAN but forgets to update the downstream trunk permit list.
