Question 280

During a planned campus-network change at a public library in Portland, operators discover that a switch is repeatedly connected and disconnected from a workstation port, creating topology churn. The design must preserve staff and visitor wireless access. Which test result most directly confirms the required behavior?

  1. Endpoint ports avoid introducing a bridge loop while legitimate inter-switch links continue exchanging BPDUs normally
  2. Tagged and untagged test frames enter their intended VLANs on both ends and unauthorized VLANs are not carried
  3. Positive and negative flow tests prove only authorized source, destination and service tuples pass
  4. Authorized lease responses pass from the approved server while a test rogue server on an edge port is blocked

Explanation

Correct Answer

A:

This observation tests the Layer-two edge protection and BPDU controls requirement at a public library in Portland. The expected result is that endpoint ports avoid introducing a bridge loop while legitimate inter-switch links continue exchanging BPDUs normally. The necessary correction is to apply appropriate edge-port STP protections and restrict unapproved downstream switching devices without blocking intended uplinks; a saved configuration alone would not prove it is working. In this case, the observed fault is that a switch is repeatedly connected and disconnected from a workstation port, creating topology churn.

Incorrect Answers

B:

At a public library in Portland, the observation may be useful for a separate VLAN trunk and native VLAN consistency test, but it does not establish that a switch is repeatedly connected and disconnected from a workstation port, creating topology churn has been resolved. The relevant check is the Layer-two edge protection and BPDU controls outcome.

C:

At a public library in Portland, this measures a different network requirement, Ingress ACL enforcement and least privilege. The case describes that a switch is repeatedly connected and disconnected from a workstation port, creating topology churn, so accepting this result would leave the primary fault without direct verification.

D:

At a public library in Portland, this would verify DHCP snooping and rogue DHCP protection, not the failure reported in this scenario. The requested closure criterion instead concerns Layer-two edge protection and BPDU controls: endpoint ports avoid introducing a bridge loop while legitimate inter-switch links continue exchanging BPDUs normally.

Question 281

At a regional hospital campus in Richmond, engineers report that a four-port uplink has two interfaces suspended due to incompatible LACP negotiation. The work affects clinical scheduling and bedside devices. What configuration or diagnostic step is the best next move?

  1. Create and validate the SVI on the correct VLAN with appropriate IP addressing, routing and permitted cross-VLAN policy
  2. Align LACP mode, speed, member selection and VLAN parameters across both aggregation endpoints
  3. Enable DHCP snooping where supported and trust only the genuine server-facing uplink, retaining clients as untrusted
  4. Apply the correctly ordered VLAN or interface ACL at the intended ingress boundary with specific permitted and denied traffic

Explanation

Correct Answer

B:

The crucial symptom at a regional hospital campus in Richmond is that a four-port uplink has two interfaces suspended due to incompatible LACP negotiation. The best response is to align LACP mode, speed, member selection and VLAN parameters across both aggregation endpoints. Confirm success by checking that the intended active members participate in one operational LAG and a single member loss does not interrupt the logical interface.

Incorrect Answers

A:

At a regional hospital campus in Richmond, that change is aimed at SVI gateway and inter-VLAN reachability, not at the actual fault: a four-port uplink has two interfaces suspended due to incompatible LACP negotiation. A successful repair here must show that the intended active members participate in one operational LAG and a single member loss does not interrupt the logical interface.

C:

At a regional hospital campus in Richmond, the option addresses DHCP snooping and rogue DHCP protection rather than the reported issue. For the stated symptom, the expected evidence is that the intended active members participate in one operational LAG and a single member loss does not interrupt the logical interface.

D:

Question 282

At a regional hospital campus in Richmond, engineers report that a four-port uplink has two interfaces suspended due to incompatible LACP negotiation. The work affects clinical scheduling and bedside devices. What evidence should the engineer request after the repair?

  2. Tagged and untagged test frames enter their intended VLANs on both ends and unauthorized VLANs are not carried
  3. Endpoint ports avoid introducing a bridge loop while legitimate inter-switch links continue exchanging BPDUs normally
  4. The intended active members participate in one operational LAG and a single member loss does not interrupt the logical interface

Explanation

Correct Answer

D:

This observation tests the LACP aggregation and member consistency requirement at a regional hospital campus in Richmond. The expected result is that the intended active members participate in one operational LAG and a single member loss does not interrupt the logical interface.

Question 283

During a planned campus-network change at a hotel campus in Vancouver, operators discover that a four-port uplink has two interfaces suspended due to incompatible LACP negotiation. The design must preserve guest access and property operations. Which change most directly addresses the stated failure?

  1. Enable DHCP snooping where supported and trust only the genuine server-facing uplink, retaining clients as untrusted
  2. Apply appropriate edge-port STP protections and restrict unapproved downstream switching devices without blocking intended uplinks
  3. Align LACP mode, speed, member selection and VLAN parameters across both aggregation endpoints
  4. Create and validate the SVI on the correct VLAN with appropriate IP addressing, routing and permitted cross-VLAN policy

B:

Although this is a valid design approach for Layer-two edge protection and BPDU controls in an appropriate case, it leaves the LACP aggregation and member consistency dependency untested. The observed condition at a hotel campus in Vancouver is that a four-port uplink has two interfaces suspended due to incompatible LACP negotiation.

  2. Endpoint ports avoid introducing a bridge loop while legitimate inter-switch links continue exchanging BPDUs normally
  3. Tagged and untagged test frames enter their intended VLANs on both ends and unauthorized VLANs are not carried
  4. Clients in each subnet reach their local gateway and only the authorized inter-VLAN flows succeed

Question 285

At a manufacturing complex in Detroit, engineers report that the peer uses a static channel while the Aruba switch is configured for dynamic LACP. The work affects production and maintenance endpoints. Which implementation choice meets this requirement without broadening access?

  1. Apply the correctly ordered VLAN or interface ACL at the intended ingress boundary with specific permitted and denied traffic
  2. Match the switchport tagging, native VLAN and allowed VLAN list on each end of the campus trunk
  3. Apply appropriate edge-port STP protections and restrict unapproved downstream switching devices without blocking intended uplinks
