Question 800

At North Library, a test client sends DHCP packets but the engineer sees none on an external capture laptop. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Configure a supported mirror session with explicit source direction and valid destination port.
  2. Protect sensitive mirrored payloads and remove temporary sessions after testing.
  3. Treat cumulative counters as rates over time rather than interpreting raw lifetime totals.
  4. Configure complementary UXI internal service and external Internet tests.

Explanation

Correct Answers

A:

This is the implementation element for the North Library case: Port mirroring copies selected frames for observation but is not a live forwarding path. The specific action Configure a supported mirror session with explicit source direction and valid destination port addresses the stated fault; the question also requires a persistent risk control.

B:

This is the continuing risk-control element for North Library. Protect sensitive mirrored payloads and remove temporary sessions after testing prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

C:

This may be an ongoing precaution for Switch telemetry counters: Interface counters help distinguish physical corruption from congestion drops. It does not resolve the Port mirroring PCAP requirement in North Library and is not one of the two controls requested. The direct mechanism here is port mirroring copies selected frames for observation but is not a live forwarding path

D:

This may be a configuration step for UXI internal and external tests: Internal and external synthetic tests isolate distinct service paths and failure domains. It does not resolve the Port mirroring PCAP requirement in North Library and is not one of the two controls requested. The direct mechanism here is port mirroring copies selected frames for observation but is not a live forwarding path

Question 801

At Technology Center, contractors successfully authenticate but receive full staff network permissions. What should be examined to confirm the actual failure mechanism?

  1. Inspect start interim and stop records mapped to the NAD and user.
  2. Inspect certificate chain expiry dates CRL/OCSP reachability and client errors.
  3. Inspect effective roles group policy and same-VLAN as well as routed flows.
  4. Inspect ClearPass policy result RADIUS attributes and effective network client role.

Explanation

Correct Answer

D:

For Technology Center, the decisive mechanism is ClearPass role-based enforcement. ClearPass decides authorization outcomes while network devices enforce assigned policy. Inspect ClearPass policy result RADIUS attributes and effective network client role is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Technology Center case, Those observations could be normal while the stated fault persists. The specific mechanism is clearPass decides authorization outcomes while network devices enforce assigned policy

B:

This is relevant to Certificate renewal workflow, where authentication availability depends on valid certificate lifecycle at both ends In the Technology Center case, Those observations could be normal while the stated fault persists. The specific mechanism is clearPass decides authorization outcomes while network devices enforce assigned policy

C:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Technology Center case, Those observations could be normal while the stated fault persists. The specific mechanism is clearPass decides authorization outcomes while network devices enforce assigned policy

Question 802

At Garden Hall, aOS 10 client tunnels land unevenly after two gateways with mismatched group attributes are joined. What recurring protection should accompany this configuration?

  1. Retain keepalive routing isolated from routine campus policy edits.
  2. Secure ISL paths and preserve independent keepalive failure domains.
  3. Preserve cluster software and resource headroom during rolling changes.
  4. Validate shared virtual gateway settings on both peers before activating a new VLAN.

Explanation

Correct Answer

C:

For Garden Hall, the decisive mechanism is AOS 10 gateway cluster. An AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy. Maintain cluster software and resource headroom during rolling changes is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Garden Hall case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy

B:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Garden Hall case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy

D:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Garden Hall case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy

Question 803

At Engineering Tower, employees report that a wireless SSID associates yet DNS queries time out sporadically. What observable outcome would prove this repair actually works?

  1. Read a test resource safely and confirm returned properties match the chosen selector.
  2. Show controlled service degradation is detected and accurately localized by UXI.
  3. Generate a test event and match timestamps and device identity at the collector.
  4. Repeat representative traffic and demonstrate counters stay within accepted thresholds.

Explanation

Correct Answer

B:

For Engineering Tower, the decisive mechanism is UXI client experience probes. UXI sensors run synthetic end-user workflows to reveal service-layer failures. Show controlled service degradation is detected and accurately localized by UXI supplies measurable, case-relevant evidence that the intended behavior actually occurs.

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 Engineering Tower case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is uXI sensors run synthetic end-user workflows to reveal service-layer failures

C:

This is relevant to Syslog timestamps and forwarding, where system logging accuracy needs both transport and synchronized timestamps In the Engineering Tower case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is uXI sensors run synthetic end-user workflows to reveal service-layer failures

D:

This is relevant to Switch telemetry counters, where interface counters help distinguish physical corruption from congestion drops In the Engineering Tower case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is uXI sensors run synthetic end-user workflows to reveal service-layer failures

Question 804

At South Science Wing, two tenants have overlapping 10.10.0.0/16 networks but must use the same campus core. Which check provides the most useful information for fixing this deployment?

  1. Compare default prefixes distances next-hop health and forwarding decisions.
  2. Inspect OSPF hello packet area values network type and adjacency state.
  3. Inspect per-VRF route tables interfaces and deliberately leaked prefixes.
  4. Inspect route table recursive next-hop resolution and ARP reachability.

Explanation

Correct Answer

C:

For South Science Wing, the decisive mechanism is VRF segmentation routing. VRFs maintain separate forwarding and routing instances on supported devices. Inspect per-VRF route tables interfaces and deliberately leaked prefixes 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 South Science Wing case, Those observations could be normal while the stated fault persists. The specific mechanism is vRFs maintain separate forwarding and routing instances on supported devices

B:

This is relevant to OSPF area membership, where oSPF neighbors on a link must agree on essential area and protocol parameters In the South Science Wing case, Those observations could be normal while the stated fault persists. The specific mechanism is vRFs maintain separate forwarding and routing instances on supported devices

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 South Science Wing case, Those observations could be normal while the stated fault persists. The specific mechanism is vRFs maintain separate forwarding and routing instances on supported devices

Question 805

At Central Hall, a secured OSPF adjacency drops after one core switch changes its authentication key. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Rotate routing keys with coordinated change control.
  2. Enable matching OSPFv3 area/interface settings with valid IPv6 transport reachability.
  3. Test preemption and split-brain behavior during a controlled pilot.
  4. Configure matching supported OSPF authentication settings on intended neighbors.

Explanation

Correct Answers

A:

This is the continuing risk-control element for Central Hall. Rotate routing keys with coordinated change control prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

D:

This is the implementation element for the Central Hall case: OSPF authentication protects adjacency formation against unauthorized peers. The specific action Configure matching supported OSPF authentication settings on intended neighbors addresses the stated fault; the question also requires a persistent risk control.

Incorrect Answers

B:

This may be a configuration step for IPv6 OSPFv3 adjacency: OSPFv3 exchanges IPv6 routing information through a separately configured protocol process. It does not resolve the OSPF neighbor authentication requirement in Central Hall and is not one of the two controls requested. The direct mechanism here is oSPF authentication protects adjacency formation against unauthorized peers

C:

This may be an ongoing precaution for First-hop gateway election: VRRP abstracts the default gateway across eligible routing devices. It does not resolve the OSPF neighbor authentication requirement in Central Hall and is not one of the two controls requested. The direct mechanism here is oSPF authentication protects adjacency formation against unauthorized peers

Question 806

At North Residence, an AOS-CX uplink migrates to Layer 3 but VLAN interfaces have incorrect IP prefixes. Which observation most directly isolates the likely cause before any change?

  1. Examine untagged packet capture and both peers native VLAN configuration.
  2. Cross-check allowed VLAN list tagging and egress counters at both ends.
  3. Examine connected routes ARP SVI status and destination routing table.
  4. Examine interface VLAN mode learned MAC address and DHCP lease subnet.

Explanation

Correct Answer

C:

For North Residence, the decisive mechanism is SVI routing enablement. An SVI is the Layer 3 gateway for an associated Layer 2 VLAN. Inspect connected routes ARP SVI status and destination routing table 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 North Residence case, Those observations could be normal while the stated fault persists. The specific mechanism is an SVI is the Layer 3 gateway for an associated Layer 2 VLAN

B:

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 North Residence case, Those observations could be normal while the stated fault persists. The specific mechanism is an SVI is the Layer 3 gateway for an associated Layer 2 VLAN

D:

This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the North Residence case, Those observations could be normal while the stated fault persists. The specific mechanism is an SVI is the Layer 3 gateway for an associated Layer 2 VLAN

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11 discovery and association occur before user traffic can be successfully forwarded

B:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11 discovery and association occur before user traffic can be successfully forwarded

C:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11 discovery and association occur before user traffic can be successfully forwarded

Question 808

At Research Hub, a finance switch uses unrestricted fail-open when both RADIUS servers fail, violating policy. Which configuration change best fits the network requirement and observed behavior?

  1. Apply supported administrative AAA command roles and TACACS+ where appropriate.
  2. Tune supported reauthentication and EAP timers based on measured client/server behavior.
  3. Define a supported critical-role or fallback profile with minimum necessary services.
  4. Activate supported 802.1X authenticator and approved ClearPass RADIUS profiles on the switchport.
