Question 130

At Central Hall, a new campus fiber uplink should be preferred but interface costs retain old values. Which configuration change best fits the network requirement and observed behavior?

  1. Activate matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  2. Establish intentional OSPF interface cost reflecting primary and backup path design.
  3. Ensure relay source and server return routing permit both directions of the DHCP exchange.
  4. Set up supported VRRP with consistent virtual IP and safe priority/failover behavior.

Explanation

Correct Answer

B:

For Central Hall, the decisive mechanism is OSPF metric selection. OSPF chooses shortest paths based on cumulative advertised link cost. Set intentional OSPF interface cost reflecting primary and backup path design establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost

C:

This is relevant to DHCP relay return routing, where dHCP relay requires a valid return path to the relay address and client network In the Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost

D:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is oSPF chooses shortest paths based on cumulative advertised link cost

Question 131

At Arts Pavilion, a softphone deployment experiences choppy audio over congested Wi-Fi while speed tests look good. What observable outcome would prove this repair actually works?

  1. Run concurrent voice and bulk traffic and measure call metrics to target.
  2. Demonstrate authorized voice gets its intended queue while bulk traffic does not.
  3. Run the target application with representative subscribers and verify latency and load.
  4. Observe suitable dual-band clients prefer 5 GHz without breaking legacy endpoints.

Explanation

Correct Answer

A:

For Arts Pavilion, the decisive mechanism is Voice jitter and packet loss. Real-time voice quality depends on delay variation and loss more than raw peak throughput. Run concurrent voice and bulk traffic and measure call metrics to target supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the Arts Pavilion case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is real-time voice quality depends on delay variation and loss more than raw peak throughput

C:

This is relevant to Multicast-to-unicast tradeoff, where multicast-to-unicast can improve delivery to small receiver groups but adds per-recipient work In the Arts Pavilion case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is real-time voice quality depends on delay variation and loss more than raw peak throughput

D:

This is relevant to Band steering under load, where band steering can guide dual-band association but depends on real RF and client support In the Arts Pavilion case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is real-time voice quality depends on delay variation and loss more than raw peak throughput

Question 132

At Riverside Building, a branch has the correct OSPF route but packets stop at the distribution firewall. Which change-management constraint best guards against recurrence?

  1. Do not broaden all enforcement results when one service policy is wrong.
  2. Retain spare supported optics and baseline error counters before maintenance.
  3. Use staged routing changes and monitor policy symmetry.
  4. Avoid bypassing AAA simply because DHCP is failing.

Explanation

Correct Answer

C:

For Riverside Building, the decisive mechanism is Routed blackhole. Route presence alone does not prove usable bidirectional forwarding. Use staged routing changes and monitor policy symmetry is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to RADIUS Access-Reject root cause, where an explicit RADIUS reject can come from credential validation or authorization policy In the Riverside Building case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is route presence alone does not prove usable bidirectional forwarding

B:

This is relevant to Physical-link errors, where layer 1/2 corruption can degrade packets even though link status remains up In the Riverside Building case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is route presence alone does not prove usable bidirectional forwarding

D:

This is relevant to DHCP address-acquisition failure, where network authorization and DHCP allocation are separate stages requiring their own diagnostics In the Riverside Building case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is route presence alone does not prove usable bidirectional forwarding

Question 133

At Technology Center, a trunk to a campus AP forwards staff frames but guest frames on VLAN 230 never reach the distribution switch. What should be examined to confirm the actual failure mechanism?

  1. Inspect local and remote LLDP chassis port and management addresses against physical patch records.
  2. Inspect switch PoE allocation operational draw power-denial and AP boot-event evidence.
  3. Inspect per-port tag membership and tagged packet captures at the failing VLAN boundary.
  4. Compare operational speed duplex FCS errors and auto-negotiation on each side of the link.

Explanation

Correct Answer

C:

For Technology Center, the decisive mechanism is 802.1Q VLAN tagging. 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links. Inspect per-port tag membership and tagged packet captures at the failing VLAN boundary is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to LLDP topology and discovery, where lLDP supplies adjacent-device identity without proving end-to-end routing or authentication In the Technology Center case, Those observations could be normal while the stated fault persists. The specific mechanism is 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links

B:

This is relevant to PoE power negotiation, where 802.3af at and bt power classes and the switch budget constrain device operation In the Technology Center case, Those observations could be normal while the stated fault persists. The specific mechanism is 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links

D:

This is relevant to Ethernet negotiation and duplex, where 802.3 physical link negotiation precedes Layer 2 and Layer 3 service validation In the Technology Center case, Those observations could be normal while the stated fault persists. The specific mechanism is 802.1Q tagging preserves logical broadcast-domain identity over shared Ethernet links

Question 134

At Engineering Tower, a campus branch configured an application route through a decommissioned firewall interface. Which test best differentiates real success from a merely healthy status light?

  1. Reach a controlled remote prefix while confirming the next hop is the intended peer.
  2. Check appropriate IPv6 routes are learned and prefixes stay reachable.
  3. Receive a correct lease from the remote DHCP server on a test client.
  4. Validate tenant isolation and narrowly authorized inter-VRF service reachability.

Explanation

Correct Answer

A:

For Engineering Tower, the decisive mechanism is Static route next hop. A static route only forwards as intended when its next hop can be resolved. Reach a controlled remote prefix while confirming the next hop is the intended peer supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Engineering Tower case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is a static route only forwards as intended when its next hop can be resolved

C:

This is relevant to DHCP relay return routing, where dHCP relay requires a valid return path to the relay address and client network In the Engineering Tower case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is a static route only forwards as intended when its next hop can be resolved

D:

This is relevant to VRF segmentation routing, where vRFs maintain separate forwarding and routing instances on supported devices In the Engineering Tower case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is a static route only forwards as intended when its next hop can be resolved

Question 135

At West Auditorium, a barcode scanner reauthenticates fully after every BSSID change because fast transition is disabled. Which check provides the most useful information for fixing this deployment?

  1. Examine Access-Request policy trace and certificate-validation logs.
  2. Examine authorized port VLAN DHCP DISCOVER/OFFER and relay counters.
  3. Examine FCS CRC counters optical levels and negotiated mode.
  4. Capture association FT and EAP timing around the roam event.

Explanation

Correct Answer

D:

For West Auditorium, the decisive mechanism is Roaming authentication stalls. Roaming interruptions can arise from authentication delay rather than RF coverage alone. Capture association FT and EAP timing around the roam event is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to RADIUS Access-Reject root cause, where an explicit RADIUS reject can come from credential validation or authorization policy In the West Auditorium case, Those observations could be normal while the stated fault persists. The specific mechanism is roaming interruptions can arise from authentication delay rather than RF coverage alone

B:

This is relevant to DHCP address-acquisition failure, where network authorization and DHCP allocation are separate stages requiring their own diagnostics In the West Auditorium case, Those observations could be normal while the stated fault persists. The specific mechanism is roaming interruptions can arise from authentication delay rather than RF coverage alone

C:

This is relevant to Physical-link errors, where layer 1/2 corruption can degrade packets even though link status remains up In the West Auditorium case, Those observations could be normal while the stated fault persists. The specific mechanism is roaming interruptions can arise from authentication delay rather than RF coverage alone

Question 136
