Question 1120

At Central Hall, a laptop passes 802.1X but receives a 169.254 address instead of the expected VLAN lease. What targeted evidence should the network engineer collect first?

  1. Inspect client effective VLAN AP forward mode tagged frames and DHCP lease.
  2. Inspect authorized port VLAN DHCP DISCOVER/OFFER and relay counters.
  3. Inspect topology-change events root path role and transition timing.
  4. Inspect routing table next-hop ARP and return-path filters hop by hop.

Explanation

Correct Answer

B:

For Central Hall, the decisive mechanism is DHCP address-acquisition failure. Network authorization and DHCP allocation are separate stages requiring their own diagnostics. Inspect authorized port VLAN DHCP DISCOVER/OFFER and relay counters is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Wrong VLAN mapping, where wLAN-to-wired mapping errors can appear as a DHCP or authorization defect In the Central Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is network authorization and DHCP allocation are separate stages requiring their own diagnostics

C:

This is relevant to STP convergence fault, where sTP role and root election determine the alternate Layer 2 forwarding path In the Central Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is network authorization and DHCP allocation are separate stages requiring their own diagnostics

D:

This is relevant to Routed blackhole, where route presence alone does not prove usable bidirectional forwarding In the Central Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is network authorization and DHCP allocation are separate stages requiring their own diagnostics

Question 1121

At Main Data Center, a guest printer port remains in the default VLAN instead of its approved IoT segment. Which controlled acceptance test demonstrates the required behavior?

  1. See device traffic only in its assigned broadcast domain and expected address scope.
  2. Verify the phone uses the voice VLAN while the PC remains in the data VLAN.
  3. Run controlled large-payload tests and confirm reliable path MTU behavior.
  4. Permit a specifically authorized app and block the matching forbidden traffic.

Explanation

Correct Answer

A:

For Main Data Center, the decisive mechanism is Access VLAN classification. An access port carries untagged frames in one configured access VLAN. See device traffic only in its assigned broadcast domain and expected address scope supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

This is relevant to Voice VLAN LLDP-MED, where lLDP-MED can advertise voice-network attributes while the switch enforces separate VLAN policies In the Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is an access port carries untagged frames in one configured access VLAN

C:

This is relevant to End-to-end MTU and frames, where a path's effective MTU is limited by the smallest supported segment and encapsulation overhead In the Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is an access port carries untagged frames in one configured access VLAN

D:

This is relevant to ACL direction and interface, where stateless ACL effectiveness depends on interface attachment direction and rule order In the Main Data Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is an access port carries untagged frames in one configured access VLAN

Question 1122

At New Teaching Block, a laptop receives Access-Accept but its switchport remains assigned to an unauthenticated VLAN. Which investigation most directly explains why the intended service is not working?

  1. Inspect EAP exchanges identity retries and reauthentication failure timestamps.
  2. Inspect command authorization logs versus client-port authentication events.
  3. Inspect RADIUS role attributes switch VLAN membership and DHCP address assignment.
  4. Inspect Access-Accept AV pairs and effective port role or VLAN assignment.

Explanation

Correct Answer

D:

For New Teaching Block, the decisive mechanism is ClearPass enforcement attributes. An Access-Accept alone does not guarantee the intended authorization role was applied. Inspect Access-Accept AV pairs and effective port role or VLAN assignment is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to Supplicant reauthentication intervals, where wired reauthentication intervals can affect session continuity if handshake timing is inadequate In the New Teaching Block case, Those observations could be normal while the stated fault persists. The specific mechanism is an Access-Accept alone does not guarantee the intended authorization role was applied

B:

This is relevant to TACACS+ admin AAA distinction, where administrative command authorization and client-port 802.1X solve different AAA problems In the New Teaching Block case, Those observations could be normal while the stated fault persists. The specific mechanism is an Access-Accept alone does not guarantee the intended authorization role was applied

C:

This is relevant to Dynamic VLAN on wired port, where dynamic VLAN assignment requires compatible RADIUS results and local switch VLAN support In the New Teaching Block case, Those observations could be normal while the stated fault persists. The specific mechanism is an Access-Accept alone does not guarantee the intended authorization role was applied

Question 1123

At Central Hall, one office radio remains overloaded while nearby capable APs have spare capacity. Which implementation directly addresses this campus fault without replacing the wrong component?

  1. Set up guest authentication flow and role transitions with appropriate enforcement.
  2. Apply supported clustered gateway configuration with capacity and software-version compatibility.
  3. Adjust mounting antenna orientation and power using active RF measurements.
  4. Apply supported ClientMatch optimization with measured AP and client behavior.

Explanation

Correct Answer

D:

For Central Hall, the decisive mechanism is ClientMatch balancing. ClientMatch can guide client association and roaming decisions based on RF and load. Apply supported ClientMatch optimization with measured AP and client behavior establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to Guest portal and role, where captive portal authentication and post-login role enforcement are separate controls In the Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is clientMatch can guide client association and roaming decisions based on RF and load

B:

This is relevant to Gateway cluster resiliency, where tunneled service resilience requires usable gateway capacity and working AP tunnels In the Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is clientMatch can guide client association and roaming decisions based on RF and load

C:

This is relevant to AP power and cell geometry, where aP placement and transmit power affect cell coverage and roaming boundaries In the Central Hall case, Changing that neighboring feature does not implement the missing function. The specific mechanism is clientMatch can guide client association and roaming decisions based on RF and load

Question 1124

At North Residence, a phone and PC share one Ethernet port yet the switch applies one role to both clients. Which investigation most directly explains why the intended service is not working?

  1. Examine separate voice and data session IDs and effective roles.
  2. Examine Access-Accept AV pairs and effective port role or VLAN assignment.
  3. Examine EAPOL handshake switch authentication state and RADIUS responses.
  4. Examine server status transport timeouts and alternate server selection.

Explanation

Correct Answer

A:

For North Residence, the decisive mechanism is Phone and PC multi-domain. Multi-domain wired access can maintain distinct voice and user authorization sessions. Inspect separate voice and data session IDs and effective roles is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

This is relevant to ClearPass enforcement attributes, where an Access-Accept alone does not guarantee the intended authorization role was applied In the North Residence case, Those observations could be normal while the stated fault persists. The specific mechanism is multi-domain wired access can maintain distinct voice and user authorization sessions

C:

This is relevant to Wired 802.1X port access, where 802.1X authorizes port traffic through EAPOL and the authentication server decision In the North Residence case, Those observations could be normal while the stated fault persists. The specific mechanism is multi-domain wired access can maintain distinct voice and user authorization sessions

D:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the North Residence case, Those observations could be normal while the stated fault persists. The specific mechanism is multi-domain wired access can maintain distinct voice and user authorization sessions

Question 1125

At Technology Center, two gateway peers advertise inconsistent VRRP virtual IP settings after maintenance. What should the engineer implement first to correct the stated condition?

  1. Set up supported VRRP virtual gateway ownership and priority on matched interfaces.
  2. Set up a separate reachable VSX keepalive path with valid source and peer addressing.
  3. Build a supported VSX ISL with enough capacity and verify peer state consistency.
  4. Set up matching active-gateway address and MAC settings on the applicable VSX SVIs.

Explanation

Correct Answer

A:

For Technology Center, the decisive mechanism is VRRP redundant gateway. VRRP supplies virtual first-hop gateway failover between eligible routing peers. Configure supported VRRP virtual gateway ownership and priority on matched interfaces establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

B:

This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is VRRP supplies virtual first-hop gateway failover between eligible routing peers

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 Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is VRRP supplies virtual first-hop gateway failover between eligible routing peers

D:

This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Technology Center case, Changing that neighboring feature does not implement the missing function. The specific mechanism is VRRP supplies virtual first-hop gateway failover between eligible routing peers

Question 1126

At Administration Block, wireless clients disconnect when a single tunnel gateway goes offline despite multiple gateways being deployed. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Build a supported VSX ISL with enough capacity and verify peer state consistency.
  2. Create a compatible gateway cluster with capacity and mobility requirements in Central.
  3. Keep keepalive routing isolated from routine campus policy edits.
  4. Maintain cluster software and resource headroom during rolling changes.

Explanation

Correct Answers

B:

This is the implementation element for the Administration Block case: An AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy. The specific action Create a compatible gateway cluster with capacity and mobility requirements in Central addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Administration Block. Maintain cluster software and resource headroom during rolling changes prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

A:

This may be a configuration step for VSX inter-switch link: VSX peers synchronize selected state over an ISL while retaining independent control planes. It does not resolve the AOS 10 gateway cluster requirement in Administration Block and is not one of the two controls requested. The direct mechanism here is an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy

C:

This may be an ongoing precaution for VSX keepalive separation: The VSX keepalive helps distinguish peer failure from ISL failure. It does not resolve the AOS 10 gateway cluster requirement in Administration Block and is not one of the two controls requested. The direct mechanism here is an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy

Question 1127

At Innovation Studio, a secure corporate SSID needs appropriate enterprise authentication and protected management frames. Which controlled acceptance test demonstrates the required behavior?

  1. Validate enterprise clients join securely with accepted ciphers and certificates.
  2. Authenticate with newly issued certificates through the whole EAP-TLS exchange.
  3. Test allowed application connectivity and rejected unauthorized east-west traffic.
  4. Correlate a test session and termination with the intended accounting records.

Explanation

Correct Answer

A:

For Innovation Studio, the decisive mechanism is WPA3 Enterprise compatibility. WPA3-Enterprise builds on supported enterprise security capabilities with stronger protections. Validate enterprise clients join securely with accepted ciphers and certificates supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

B:

This is relevant to Certificate renewal workflow, where authentication availability depends on valid certificate lifecycle at both ends In the Innovation Studio case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections

C:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the Innovation Studio case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections

D:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the Innovation Studio case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections

Question 1128

At Central Hall, a school EAP-TLS service stops accepting clients after the intermediate CA expires. Which observation most directly isolates the likely cause before any change?

  2. Inspect ClearPass policy result RADIUS attributes and effective network client role.
  3. Inspect association RSN capability and failed security negotiation status.
  4. Inspect RSN capability PMF requirement and association refusal codes.

Explanation

Correct Answer

A:

For Central Hall, the decisive mechanism is Certificate renewal workflow. Authentication availability depends on valid certificate lifecycle at both ends. Inspect certificate chain expiry dates CRL/OCSP reachability and client errors is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

B:

This is relevant to ClearPass role-based enforcement, where clearPass decides authorization outcomes while network devices enforce assigned policy In the Central Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is authentication availability depends on valid certificate lifecycle at both ends

C:

This is relevant to WPA3 Enterprise compatibility, where wPA3-Enterprise builds on supported enterprise security capabilities with stronger protections In the Central Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is authentication availability depends on valid certificate lifecycle at both ends

D:

This is relevant to Protected management frames, where protected management frames reduce forgery of eligible robust management frames In the Central Hall case, Those observations could be normal while the stated fault persists. The specific mechanism is authentication availability depends on valid certificate lifecycle at both ends

Question 1129

At Convention Center, an access network changes authentication timeout settings but client EAP exchanges exceed them. Which postchange observation is the strongest evidence of correct operation?

  1. Demonstrate the accepted identity receives the intended permissions and IP subnet.
  2. Block the primary in a lab and verify configured fallback behavior.
  3. Connect a managed laptop and verify authorized access only after authentication.
  4. Preserve authenticated sessions through the expected timer cycle in a controlled test.

Explanation

Correct Answer

D:

For Convention Center, the decisive mechanism is Supplicant reauthentication intervals. Wired reauthentication intervals can affect session continuity if handshake timing is inadequate. Maintain authenticated sessions through the expected timer cycle in a controlled test supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

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, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate

B:

This is relevant to RADIUS authorization timeout, where authentication server reachability and retry order influence network-admission decisions In the Convention Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate

C:

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, That test could pass while the actual user-facing requirement still fails. The specific mechanism is wired reauthentication intervals can affect session continuity if handshake timing is inadequate

Question 1130

At Main Data Center, two aggregation switches report OSPF Init and Down cycles after one interface timer change. Which check provides the most useful information for fixing this deployment?

  1. Inspect VRRP advertisements gateway owner and virtual MAC state.
  2. Inspect IPv6 link-local neighbors OSPFv3 interface area and router ID.
  3. Inspect active equal-cost routes flow hashing and actual per-link counters.
  4. Inspect received hello timers and neighbor reset reasons.

Explanation

Correct Answer

D:

For Main Data Center, the decisive mechanism is OSPF hello and dead timers. OSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists. Inspect received hello timers and neighbor reset reasons is the most direct way to isolate this particular failure before making a change.

Incorrect Answers

A:

This is relevant to First-hop gateway election, where VRRP abstracts the default gateway across eligible routing devices In the Main Data Center case, Those observations could be normal while the stated fault persists. The specific mechanism is oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists

B:

This is relevant to IPv6 OSPFv3 adjacency, where oSPFv3 exchanges IPv6 routing information through a separately configured protocol process In the Main Data Center case, Those observations could be normal while the stated fault persists. The specific mechanism is oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists

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 Main Data Center case, Those observations could be normal while the stated fault persists. The specific mechanism is oSPF timer mismatches can prevent reliable adjacency even when IP connectivity exists
