Question 1010

At Convention Center, an access network changes authentication timeout settings but client EAP exchanges exceed them. Which configuration change best fits the network requirement and observed behavior?

  1. Activate supported 802.1X authenticator and approved ClearPass RADIUS profiles on the switchport.
  2. Tune supported reauthentication and EAP timers based on measured client/server behavior.
  3. Set up appropriate RADIUS failover and tested timeout/retry settings.
  4. Return supported VLAN or role attributes that match network enforcement configuration.

Explanation

Correct Answer

B:

For Convention Center, the decisive mechanism is Supplicant reauthentication intervals. Wired reauthentication intervals can affect session continuity if handshake timing is inadequate. Tune supported reauthentication and EAP timers based on measured client/server behavior establishes the needed configuration in the case rather than merely measuring a symptom.

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 Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate

C:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the Convention Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate

D:

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, Changing that neighboring feature does not implement the missing function. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate

Question 1011

At Transit Operations Center, a cloned distribution switch shares an OSPF router ID and adjacency becomes unstable. Which preventive control is most relevant to this scenario over time?

  1. Audit IPv4/IPv6 protocol operation separately rather than assuming dual-stack parity.
  2. Test preemption and split-brain behavior during a controlled pilot.
  3. Check return-path symmetry and middlebox state before broad ECMP changes.
  4. Include router IDs in switch provisioning validation.

Explanation

Correct Answer

D:

For Transit Operations Center, the decisive mechanism is OSPF router ID uniqueness. An OSPF router ID identifies a routing instance independently of VLAN labels. Include router IDs in switch provisioning validation is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Transit Operations Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is an OSPF router ID identifies a routing instance independently of VLAN labels

B:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Transit Operations Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is an OSPF router ID identifies a routing instance independently of VLAN labels

C:

This is relevant to ECMP next-hop selection, where eCMP typically spreads flows over equal-cost next hops, not necessarily one flow packet by packet In the Transit Operations Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is an OSPF router ID identifies a routing instance independently of VLAN labels

Question 1012

At Convention Center, a BYOD device presents an untrusted issuing CA in enterprise EAP-TLS onboarding. How should the engineer validate success against the stated requirement?

  1. Test allowed application connectivity and rejected unauthorized east-west traffic.
  2. Check approved administrators connect while ordinary user subnets cannot.
  3. Prove a trusted unexpired certificate succeeds while an untrusted client fails.
  4. Correlate a test session and termination with the intended accounting records.

Explanation

Correct Answer

C:

For Convention Center, the decisive mechanism is EAP-TLS client certificate validation. EAP-TLS authenticates possession of the client certificate private key and validates trust. Prove a trusted unexpired certificate succeeds while an untrusted client fails supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is eAP-TLS authenticates possession of the client certificate private key and validates trust

B:

This is relevant to Management plane protection, where data-plane forwarding policy does not automatically secure device management services In the Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is eAP-TLS authenticates possession of the client certificate private key and validates trust

D:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is eAP-TLS authenticates possession of the client certificate private key and validates trust

A:

This is relevant to Management VRF reachability, where aOS-CX management VRF and default forwarding VRF may have separate reachability In the South Science Wing case, Those observations could be normal while the stated fault persists. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

B:

This is relevant to Central group assignment, where central groups govern configuration inheritance while sites mainly aid location and operations In the South Science Wing case, Those observations could be normal while the stated fault persists. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

D:

This is relevant to Central device onboarding, where cloud inventory association and device management connectivity are separate onboarding requirements In the South Science Wing case, Those observations could be normal while the stated fault persists. The specific mechanism is aP service onboarding depends on both physical power and the upstream management network

Question 1014

At Learning Commons, a mobile scanner pauses while searching the full channel list for roaming candidates. What safety boundary prevents the same campus failure in future deployments?

  1. Retain rollout headroom and test gateway interoperability during upgrades.
  2. Avoid compensating for poor placement only by increasing transmit power.
  3. Check client feature compatibility rather than assuming reports force movement.
  4. Keep guest clients isolated from internal networks throughout portal state changes.

Explanation

Correct Answer

C:

For Learning Commons, the decisive mechanism is 802.11k neighbor information. 802.11k provides radio-resource neighbor information to assist client decisions. Check client feature compatibility rather than assuming reports force movement is an enduring limitation on the operational risk, not simply a one-time passing test.

Incorrect Answers

A:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Learning Commons case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11k provides radio-resource neighbor information to assist client decisions

B:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Learning Commons case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11k provides radio-resource neighbor information to assist client decisions

D:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Learning Commons case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is 802.11k provides radio-resource neighbor information to assist client decisions

Question 1015

At Engineering Tower, an access switch becomes STP root after a firmware replacement and traffic takes a long path. What should be examined to confirm the actual failure mechanism?

  1. Inspect keepalive reachability and failure signals independently of ISL health.
  2. Inspect STP root ID path cost role and state across campus VLANs.
  3. Inspect ISL link state VSX peer status and interfaces carrying cross-peer traffic.
  4. Compare configured and operational gateway state and ARP entries on both VSX peers.

Explanation

Correct Answer

B:

For Engineering Tower, the decisive mechanism is RSTP root placement. RSTP uses a root bridge and port roles to build a loop-free Layer 2 topology. Inspect STP root ID path cost role and state across campus VLANs is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Engineering Tower case, Those observations could be normal while the stated fault persists. The specific mechanism is rSTP uses a root bridge and port roles to build a loop-free Layer 2 topology

C:

This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Engineering Tower case, Those observations could be normal while the stated fault persists.

  2. Treat cumulative counters as rates over time rather than interpreting raw lifetime totals.
  3. Protect log retention and authenticated time synchronization.
  4. Protect sensor credentials and distinguish synthetic monitoring from every client experience.

Explanation

Correct Answer

D:

For Engineering Tower, the decisive mechanism is UXI client experience probes. UXI sensors run synthetic end-user workflows to reveal service-layer failures. Protect sensor credentials and distinguish synthetic monitoring from every client experience is an enduring limitation on the operational risk, not simply a one-time passing test.

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, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is uXI sensors run synthetic end-user workflows to reveal service-layer failures

B:
