Question 470

A network team reports the following condition: An uplink needs to limit one large backup application's bandwidth. Select the most appropriate response.

Check negotiated HE capability and scheduler/radio utilization.
Apply suitable shaping or policing based on desired behavior.
Consider supported airtime fairness and data-rate policy.
Inspect flow-hash distribution and per-member traffic.

Explanation

Correct Answer

Shaping buffers over-rate traffic while policing can drop or remark it. The engineer should apply suitable shaping or policing based on desired behavior.

Incorrect Answers

OFDMA benefits depend on both AP and client support and actual traffic mix. It is not a direct remedy for the condition described.

Equal byte throughput is not the same as equal shared radio airtime. It is not a direct remedy for the condition described.

LAG hashing keeps a flow on one member and does not split one flow packet by packet. It is not a direct remedy for the condition described.

Question 471

A network team reports the following condition: A static route should silently drop a known invalid destination prefix. Select the most appropriate response.

Configure appropriate IPv6 RA behavior on the routed SVI.
Configure DHCP relay/helper on the appropriate routed interface.
Use a supported blackhole/null route in the proper VRF.
Correct inconsistent static/default routes or route redistribution.

Explanation

Correct Answer

Null-route forwarding disposes packets without a normal next hop. The engineer should use a supported blackhole/null route in the proper VRF.

Incorrect Answers

Incorrect Answers

ARP resolves IPv4 neighbors to MAC addresses within the local broadcast domain. That observation tests a different condition, not the required result.

Same-channel cells share contention opportunities even when SSIDs are identical. That observation tests a different condition, not the required result.

VLAN assignment determines the broadcast domain in which the DHCP exchange occurs. That observation tests a different condition, not the required result.

Question 475

An engineer is planning corrective work because a wireless AP exceeds the power available from its switch port. Which step should be prioritized?

Match the AP power requirement with a supported 802.3af/at/bt PoE budget.
Verify Ethernet VLAN membership before troubleshooting a Layer 3 route.
Revisit 802.11 channel reuse and neighboring co-channel cell placement.
Use 802.1Q VLAN tags to preserve the correct broadcast domains.

Explanation

Correct Answer

PoE classes and available per-port power affect whether an AP can enable full capability. The engineer should match the AP power requirement with a supported 802.3af/at/bt PoE budget.

Incorrect Answers

VLAN assignment determines the broadcast domain in which the DHCP exchange occurs. It is not a direct remedy for the condition described.

Same-channel cells share contention opportunities even when SSIDs are identical. It is not a direct remedy for the condition described.

VLAN tags identify individual logical Layer 2 networks on a shared trunk. It is not a direct remedy for the condition described.

Question 476

Following a campus change for this issue—only one VLAN cannot traverse an otherwise working trunk—which result most directly verifies that the remedy works?

Correlate channel utilization and retry peaks.
Trace one permitted and denied test flow against hit counters.
Capture affected VLAN tags at both ends.
Compare OSPF neighbor state and MTU.

Explanation

Correct Answer

A trunk can pass some VLANs while filtering another. Capture affected VLAN tags at both ends directly tests the desired behavior.

Incorrect Answers

Competing transmitters on the same channel can drive delay and retries. That observation tests a different condition, not the required result.

ACL ordering and attachment point determine real packet authorization. That observation tests a different condition, not the required result.

OSPF DBD exchange can be impeded by incompatible link parameters. That observation tests a different condition, not the required result.

Question 477

Following a campus change for this issue—two uplink members in a LAG are connected to unrelated switches with no multichassis design—which result most directly verifies that the remedy works?

Verify learned MAC addresses and client DHCP on the configured access VLAN.
Follow VLAN membership from phone access port to its routed SVI.
Inject a controlled BPDU and review protection event and port state.
Inspect the LACP partner system IDs and selected member states.
