Question 240

The HPE AOS-CX switching case is: One of two LAG ports negotiates a different speed and the aggregate reports a rejected or suspended member. Select TWO: a corrective switching action and separate evidence that the correction worked. (Select TWO.)

  1. A hop-by-hop tag trace proves required VLANs pass and disallowed VLANs are absent on all uplinks.
  2. Form LAG interfaces with consistent LACP settings, eligible member speeds and partner wiring, then evaluate per-flow hashing limitations.
  3. Build a supported VSF stack with a defined conductor, member identities and split-detection design while validating management and data forwarding.
  4. Set a consistent MSTP region name, revision and VLAN-to-instance mapping and deliberately place the root where the topology requires.
  5. The operational LACP partner and member states agree and a controlled link-failure and multi-flow throughput test passes.

Explanation

Correct Answers

B:

The targeted correction for One of two LAG ports negotiates a different speed and the aggregate reports a rejected or suspended member is: Form LAG interfaces with consistent LACP settings, eligible member speeds and partner wiring, then evaluate per-flow hashing limitations. It reduces the risk that a partially formed aggregation can strand traffic or produce surprising throughput because a single flow usually hashes to one member.

E:

A separate operational validation for One of two LAG ports negotiates a different speed and the aggregate reports a rejected or suspended member is: The operational LACP partner and member states agree and a controlled link-failure and multi-flow throughput test passes. It proves intended behavior instead of accepting configuration presence alone.

Incorrect Answers

A:

This alternative concerns vlan trunk tagging and permitted vlan filters; its associated risk is: A missing tagged VLAN on one hop silently isolates clients, while unintended VLAN allowance bridges security domains. The observed case One of two LAG ports negotiates a different speed and the aggregate reports a rejected or suspended member requires the more specific lacp member selection and load distribution control. The targeted action is: Form LAG interfaces with consistent LACP settings, eligible member speeds and partner wiring, then evaluate per-flow hashing limitations.

C:

This alternative concerns vsf single-logical-switch stack service; its associated risk is: Incorrect member order or split handling can leave orphaned interfaces and interrupt a shared access stack. The observed case One of two LAG ports negotiates a different speed and the aggregate reports a rejected or suspended member requires the more specific lacp member selection and load distribution control. The targeted action is: Form LAG interfaces with consistent LACP settings, eligible member speeds and partner wiring, then evaluate per-flow hashing limitations.

D:

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 One of two LAG ports negotiates a different speed and the aggregate reports a rejected or suspended member requires the more specific lacp member selection and load distribution control. The targeted action is: Form LAG interfaces with consistent LACP settings, eligible member speeds and partner wiring, then evaluate per-flow hashing limitations.

Question 241

An HPE Aruba Networking engineer observes: A campus core uses a different MST region revision than access switches and traffic follows an unexpected blocked path. The corrective solution must keep intended connectivity, segmentation, and operational resilience. Which change best addresses the observed switching requirement?

  1. Configure and validate tagged VLAN membership across each uplink and consistent native VLAN treatment where required by the topology.
  2. Form LAG interfaces with consistent LACP settings, eligible member speeds and partner wiring, then evaluate per-flow hashing limitations.
  3. Set a consistent MSTP region name, revision and VLAN-to-instance mapping and deliberately place the root where the topology requires.
  4. Assign user ports to the intended access VLAN and verify that untagged frames reach the proper broadcast domain.

Explanation

Correct Answer

C:

The decisive observed condition is: A campus core uses a different MST region revision than access switches and traffic follows an unexpected blocked path. The appropriate switching action is: Set a consistent MSTP region name, revision and VLAN-to-instance mapping and deliberately place the root where the topology requires. It addresses the risk that a mismatched MSTP region or unintended root can block critical trunks or increase convergence disruption. Confirm with: Spanning-tree show output confirms expected instance membership, root IDs and port forwarding or blocking roles.

Incorrect Answers

A:

This alternative concerns vlan trunk tagging and permitted vlan filters; its associated risk is: A missing tagged VLAN on one hop silently isolates clients, while unintended VLAN allowance bridges security domains. The observed case A campus core uses a different MST region revision than access switches and traffic follows an unexpected blocked path requires the more specific mstp configuration and loop control control.

The targeted action is: Set a consistent MSTP region name, revision and VLAN-to-instance mapping and deliberately place the root where the topology requires.

D:

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 A campus core uses a different MST region revision than access switches and traffic follows an unexpected blocked path requires the more specific mstp configuration and loop control control. The targeted action is: Set a consistent MSTP region name, revision and VLAN-to-instance mapping and deliberately place the root where the topology requires.

Question 242

An engineer investigates: A campus core uses a different MST region revision than access switches and traffic follows an unexpected blocked path. What network observation should the team require before approving completion?

  1. Spanning-tree show output confirms expected instance membership, root IDs and port forwarding or blocking roles.
  2. A hop-by-hop tag trace proves required VLANs pass and disallowed VLANs are absent on all uplinks.
  3. The operational LACP partner and member states agree and a controlled link-failure and multi-flow throughput test passes.
  4. Two test hosts in the same allowed VLAN exchange traffic while a restricted VLAN host remains separated as designed.

Explanation

Correct Answer

A:

The independent acceptance evidence for A campus core uses a different MST region revision than access switches and traffic follows an unexpected blocked path is: Spanning-tree show output confirms expected instance membership, root IDs and port forwarding or blocking roles. It tests whether the team has actually implemented: Set a consistent MSTP region name, revision and VLAN-to-instance mapping and deliberately place the root where the topology requires. An enabled interface or saved configuration by itself is not evidence of complete service recovery.

Question 243

An HPE Aruba Networking engineer observes: An unapproved access switch becomes the STP root after a restart because no root priority policy was established. The corrective solution must keep intended connectivity, segmentation, and operational resilience. What is the most defensible operational action before closing the network change?

  1. Configure and validate tagged VLAN membership across each uplink and consistent native VLAN treatment where required by the topology.
  2. Set a consistent MSTP region name, revision and VLAN-to-instance mapping and deliberately place the root where the topology requires.
  3. Assign user ports to the intended access VLAN and verify that untagged frames reach the proper broadcast domain.
  4. Form LAG interfaces with consistent LACP settings, eligible member speeds and partner wiring, then evaluate per-flow hashing limitations.
