Question 60

At East Student Center, iPv6 routes stop propagating after an interface is moved to a new VLAN. Which test best differentiates real success from a merely healthy status light?

  1. Verify Internet-bound test flows use the intended route while campus-specific routes remain valid.
  2. Reach a controlled remote prefix while confirming the next hop is the intended peer.
  3. Confirm appropriate IPv6 routes are learned and prefixes stay reachable.
  4. Verify Full adjacency and appropriate route propagation for a test network.

Explanation

Correct Answer

C:

For East Student Center, the decisive mechanism is IPv6 OSPFv3 adjacency. OSPFv3 exchanges IPv6 routing information through a separately configured protocol process. Confirm appropriate IPv6 routes are learned and prefixes stay reachable supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Default route selection, where default route 0.0.0.0/0 applies when no more specific IPv4 route matches In the East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPFv3 exchanges IPv6 routing information through a separately configured protocol process

B:

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

D:

This is relevant to OSPF area membership, where oSPF neighbors on a link must agree on essential area and protocol parameters In the East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is oSPFv3 exchanges IPv6 routing information through a separately configured protocol process

Question 61

At Bayside Campus, a meeting center runs a wide channel plan that causes heavy overlapping radio contention. Which configuration change best fits the network requirement and observed behavior?

  1. Evaluate supported multicast conversion and membership control for the audience size.
  2. Classify trusted voice and remark untrusted DSCP at the correct campus boundary.
  3. Tune supported band steering with proper 5-GHz coverage and compatibility checks.
  4. Evaluate narrower legal channel width and more independent reuse channels under dense load.

Explanation

Correct Answer

D:

For Bayside Campus, the decisive mechanism is RF channel width optimization. Narrower channels can improve dense-channel reuse despite reducing peak link rate. Evaluate narrower legal channel width and more independent reuse channels under dense load establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

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 Bayside Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is narrower channels can improve dense-channel reuse despite reducing peak link rate

B:

This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the Bayside Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is narrower channels can improve dense-channel reuse despite reducing peak link rate

C:

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 Bayside Campus case, Changing that neighboring feature does not implement the missing function. The specific mechanism is narrower channels can improve dense-channel reuse despite reducing peak link rate

Question 62

At West Clinic, a new AP is online but broadcasts the campus test SSID rather than the assigned building WLAN. What recurring protection should accompany this configuration?

  1. Assess roaming and segmentation impacts before changing WLAN forwarding mode.
  2. Prevent independent links from creating a Layer 2 loop during LAG migrations.
  3. Treat AP port changes as staged network access changes rather than bypassing admission.
  4. Apply peer review for group moves that can change many APs or switches simultaneously.

Explanation

Correct Answer

D:

For West Clinic, the decisive mechanism is Central group assignment. Central groups govern configuration inheritance while sites mainly aid location and operations. Use peer review for group moves that can change many APs or switches simultaneously is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to Bridge versus tunneled WLAN traffic, where bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy In the West Clinic case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is central groups govern configuration inheritance while sites mainly aid location and operations

B:

This is relevant to LACP uplink provisioning, where lACP forms one logical bundle only when peers agree on aggregation parameters In the West Clinic case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is central groups govern configuration inheritance while sites mainly aid location and operations

C:

This is relevant to AP uplink physical mapping, where aP service onboarding depends on both physical power and the upstream management network In the West Clinic case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is central groups govern configuration inheritance while sites mainly aid location and operations

Question 63

At Research Hub, an outbound route map permits more-specific subnets beyond approved advertised aggregates. Which check provides the most useful information for fixing this deployment?

  1. Cross-check default prefixes distances next-hop health and forwarding decisions.
  2. Examine exported prefix list evaluation and neighbor advertised-routes.
  3. Examine OSPF hello packet area values network type and adjacency state.
  4. Examine route table recursive next-hop resolution and ARP reachability.

Explanation

Correct Answer

B:

For Research Hub, the decisive mechanism is BGP prefix filtering. BGP route filters control prefix advertisement and must account for length matching. Inspect exported prefix list evaluation and neighbor advertised-routes is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Default route selection, where default route 0.0.0.0/0 applies when no more specific IPv4 route matches In the Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is bGP route filters control prefix advertisement and must account for length matching

C:

This is relevant to OSPF area membership, where oSPF neighbors on a link must agree on essential area and protocol parameters In the Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is bGP route filters control prefix advertisement and must account for length matching

D:

This is relevant to Static route next hop, where a static route only forwards as intended when its next hop can be resolved In the Research Hub case, Those observations could be normal while the stated fault persists. The specific mechanism is bGP route filters control prefix advertisement and must account for length matching

Question 64

At Arts Pavilion, a classroom lab floods multicast traffic and creates queue loss on the uplink. What should be examined to confirm the actual failure mechanism?

  1. Examine untagged packet capture and both peers native VLAN configuration.
  2. Cross-check broadcast multicast rate and threshold/drop counters during the incident.
  3. Examine interface VLAN mode learned MAC address and DHCP lease subnet.
  4. Cross-check allowed VLAN list tagging and egress counters at both ends.

Explanation

Correct Answer

B:

For Arts Pavilion, the decisive mechanism is Broadcast storm control. Storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops. Compare broadcast multicast rate and threshold/drop counters during the incident is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Native VLAN mismatch, where a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk In the Arts Pavilion case, Those observations could be normal while the stated fault persists. The specific mechanism is storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops

C:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the Arts Pavilion case, Those observations could be normal while the stated fault persists. The specific mechanism is storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops

D:

This is relevant to Tagged trunk allowlist, where a VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration In the Arts Pavilion case, Those observations could be normal while the stated fault persists. The specific mechanism is storm control can rate-limit unwanted Layer 2 floods but does not remove physical loops

Question 65

At Research Hub, a campus has two ISP exits and outbound traffic takes the less preferred link. Which configuration change best fits the network requirement and observed behavior?

  1. Restore an authorized default next hop and deliberate route preferences.
  2. Align OSPF area ID and supported area type at both neighboring interfaces.
  3. Apply reviewed BGP local-preference policy consistently within the relevant AS.
  4. Install a valid static route with a resolvable next hop and appropriate administrative distance.

Explanation

Correct Answer

C:

For Research Hub, the decisive mechanism is BGP local preference. Local preference guides outbound BGP best-path selection inside one autonomous system. Apply reviewed BGP local-preference policy consistently within the relevant AS establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to Default route selection, where default route 0.0.0.0/0 applies when no more specific IPv4 route matches In the Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is local preference guides outbound BGP best-path selection inside one autonomous system

B:

This is relevant to OSPF area membership, where oSPF neighbors on a link must agree on essential area and protocol parameters In the Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is local preference guides outbound BGP best-path selection inside one autonomous system

D:

This is relevant to Static route next hop, where a static route only forwards as intended when its next hop can be resolved In the Research Hub case, Changing that neighboring feature does not implement the missing function. The specific mechanism is local preference guides outbound BGP best-path selection inside one autonomous system

Question 66

At North Library, a test client sends DHCP packets but the engineer sees none on an external capture laptop. Which AOS-CX or Aruba networking design choice resolves this specific dependency?

  1. Use documented REST selectors and read writable fields before controlled updates.
  2. Configure a supported mirror session with explicit source direction and valid destination port.
  3. Collect interface error discard and utilization counters with suitable baseline intervals.
  4. Configure complementary UXI internal service and external Internet tests.

Explanation

Correct Answer

B:

For North Library, the decisive mechanism is Port mirroring PCAP. Port mirroring copies selected frames for observation but is not a live forwarding path. Configure a supported mirror session with explicit source direction and valid destination port establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to REST API selector use, where rEST representation selection and HTTP method choice affect what configuration is retrieved or changed In the North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is port mirroring copies selected frames for observation but is not a live forwarding path

C:

This is relevant to Switch telemetry counters, where interface counters help distinguish physical corruption from congestion drops In the North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is port mirroring copies selected frames for observation but is not a live forwarding path

D:

This is relevant to UXI internal and external tests, where internal and external synthetic tests isolate distinct service paths and failure domains In the North Library case, Changing that neighboring feature does not implement the missing function. The specific mechanism is port mirroring copies selected frames for observation but is not a live forwarding path

Question 67

At Convention Center, a contractor authenticates correctly but receives an employee DHCP subnet. Which check provides the most useful information for fixing this deployment?

  1. Inspect server status transport timeouts and alternate server selection.
  2. Inspect Access-Accept AV pairs and effective port role or VLAN assignment.
  3. Inspect RADIUS role attributes switch VLAN membership and DHCP address assignment.
  4. Inspect MAB attempt matched endpoint identity and ClearPass policy.

Explanation

Correct Answer

C:

For Convention Center, the decisive mechanism is Dynamic VLAN on wired port. Dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support. Inspect RADIUS role attributes switch VLAN membership and DHCP address assignment is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the Convention Center case, Those observations could be normal while the stated fault persists. The specific mechanism is dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support

B:

This is relevant to ClearPass enforcement attributes, where an Access-Accept alone does not guarantee the intended authorization role was applied In the Convention Center case, Those observations could be normal while the stated fault persists. The specific mechanism is dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support

D:

This is relevant to MAB for headless IoT, where mAB is a weaker fallback identity mechanism than certificate-based 802.1X In the Convention Center case, Those observations could be normal while the stated fault persists. The specific mechanism is dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support

Question 68

At Athletics Complex, a fiber uplink remains operational but CRC errors spike after an optic replacement. Which configuration change best fits the network requirement and observed behavior?

  1. Correct STP root priorities and protect edge or downstream boundaries as appropriate.
  2. Trace the forward and reverse forwarding path including route recursion and ACLs.
  3. Examine optics cabling transceiver support and duplex/speed at both ends before changing routes.
  4. Correct SSID-to-VLAN and switch trunk membership for the intended segment.

Explanation

For Athletics Complex, the decisive mechanism is Physical-link errors. Layer 1/2 corruption can degrade packets even though link status remains up. Examine optics cabling transceiver support and duplex/speed at both ends before changing routes establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to STP convergence fault, where sTP role and root election determine the alternate Layer 2 forwarding path In the Athletics Complex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is layer 1/2 corruption can degrade packets even though link status remains up

B:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Athletics Complex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is layer 1/2 corruption can degrade packets even though link status remains up

D:

This is relevant to Wrong VLAN mapping, where wLAN-to-wired mapping errors can appear as a DHCP or authorization defect In the Athletics Complex case, Changing that neighboring feature does not implement the missing function. The specific mechanism is layer 1/2 corruption can degrade packets even though link status remains up

Question 69

At Innovation Studio, a laptop repeatedly disconnects during short wired reauthentication cycles. Which change-management constraint best guards against recurrence?

  2. Version enforcement profiles and test against the deployed switch software.
  3. Do not broadly fail-open protected ports on temporary RADIUS loss.
  4. Avoid shrinking timers purely for perceived security without measuring disruption.

Explanation

Correct Answer

D:

For Innovation Studio, the decisive mechanism is Supplicant reauthentication intervals. Wired reauthentication intervals can affect session continuity if handshake timing is inadequate. Avoid shrinking timers purely for perceived security without measuring disruption is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to Wired 802.1X port access, where 802.1X authorizes port traffic through EAPOL and the authentication server decision In the Innovation Studio case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate

B:

This is relevant to ClearPass enforcement attributes, where an Access-Accept alone does not guarantee the intended authorization role was applied In the Innovation Studio case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate
