Question 800
A wired EAP-TLS client repeatedly requests a password even though its device certificate is installed. Which THREE steps together deliver the change, verify its effect, and reduce rollout risk? Choose THREE.
- Check the selected route, return path, ACL and actual firewall/state policy
- Compare the SSID profile, assigned role/VLAN and upstream switch tagging
- Inspect certificate trust, supplicant EAP method and RADIUS failure codes
- Pilot the corrected supplicant profile and preserve a safe enrollment network
- Test one repaired port and maintain rollback for the firmware change
- Compare EAP exchange and certificate selection to the intended authentication profile
Explanation
Correct Answers
C:A wrong EAP profile or trust chain can surface as a generic login prompt. Handshake evidence identifies credential versus configuration error.
D:Devices need a recovery path for certificate-profile mistakes. Handshake evidence identifies credential versus configuration error.
F:Handshake evidence identifies credential versus configuration error. A wrong EAP profile or trust chain can surface as a generic login prompt.
Incorrect Answers
A:Control-plane learning does not guarantee data-plane delivery. By contrast, a wrong EAP profile or trust chain can surface as a generic login prompt.
B:Device management and client data can use different network paths. In this situation, a wrong EAP profile or trust chain can surface as a generic login prompt.
E:Change control limits collateral impact. It would not resolve the documented symptom; devices need a recovery path for certificate-profile mistakes.
Question 801
A wired EAP-TLS client repeatedly requests a password even though its device certificate is installed. What should the team inspect to confirm the result?
- Capture the first failed DNS or HTTP redirect request and inspect policy logs
- Trace both directions and inspect permit/deny counters for a test flow
- Compare EAP exchange and certificate selection to the intended authentication profile
- Correlate server resource graphs, request latency and failed user sessions
Explanation
Correct Answer
C:Handshake evidence identifies credential versus configuration error. A wrong EAP profile or trust chain can surface as a generic login prompt.
Incorrect Answers
A:The earliest failing step identifies the correct team. By contrast, handshake evidence identifies credential versus configuration error.
B:The failure may be after route selection. The relevant technical distinction is that handshake evidence identifies credential versus configuration error.
D:Matching peaks demonstrate the backend bottleneck. It would not resolve the documented symptom; handshake evidence identifies credential versus configuration error.
Question 802
A wired EAP-TLS client repeatedly requests a password even though its device certificate is installed. Which TWO actions together implement the required change and verify that it works? Choose TWO.
- Compare EAP exchange and certificate selection to the intended authentication profile
- Compare the SSID profile, assigned role/VLAN and upstream switch tagging
- Inspect certificate trust, supplicant EAP method and RADIUS failure codes
- Investigate RADIUS response time and server capacity rather than endpoint signal alone
- Test one repaired port and maintain rollback for the firmware change
Explanation
Correct Answers
A:Handshake evidence identifies credential versus configuration error. A wrong EAP profile or trust chain can surface as a generic login prompt.
C:A wrong EAP profile or trust chain can surface as a generic login prompt. Handshake evidence identifies credential versus configuration error.
Incorrect Answers
B:Device management and client data can use different network paths. By contrast, a wrong EAP profile or trust chain can surface as a generic login prompt.
D:Overloaded authentication infrastructure can delay otherwise correct exchanges. Here, however, a wrong EAP profile or trust chain can surface as a generic login prompt.
E:Change control limits collateral impact. The relevant technical distinction is that devices need a recovery path for certificate-profile mistakes.
Question 803
A wired EAP-TLS client repeatedly requests a password even though its device certificate is installed. What precaution is most important before the change is expanded?
- Pilot the corrected supplicant profile and preserve a safe enrollment network
- Alert on monitoring data age and confirm user impact before mass changes
- Test secondary next-hop reachability before enabling a broad route change
- Document the replaced component and confirm port errors remain stable
Explanation
Correct Answer
A:Devices need a recovery path for certificate-profile mistakes. Handshake evidence identifies credential versus configuration error.
Incorrect Answers
B:Operational decisions should use current evidence. Here, however, devices need a recovery path for certificate-profile mistakes.
C:A fix should preserve intended failover behavior. The relevant technical distinction is that devices need a recovery path for certificate-profile mistakes.
D:Intermittent media faults can recur after short tests. In this situation, devices need a recovery path for certificate-profile mistakes.
Question 804
A distribution switch learns an OSPF route but a test host still cannot reach the subnet. Which configuration decision most directly resolves the situation?
- Test path MTU, interface errors and queue drops under realistic packet sizes
- Check client role enforcement, local VLAN transport and gateway ARP before blaming RF
- Compare the SSID profile, assigned role/VLAN and upstream switch tagging
- Check the selected route, return path, ACL and actual firewall/state policy
Explanation
Correct Answer
D:Control-plane learning does not guarantee data-plane delivery. The failure may be after route selection.
Incorrect Answers
A:Size and load sensitivity can indicate MTU or congestion instead of simple reachability. It would not resolve the documented symptom; control-plane learning does not guarantee data-plane delivery.
B:Association and DHCP do not guarantee permitted gateway forwarding. In this situation, control-plane learning does not guarantee data-plane delivery.
C:Device management and client data can use different network paths. Here, however, control-plane learning does not guarantee data-plane delivery.
Question 805
A distribution switch learns an OSPF route but a test host still cannot reach the subnet. Which check most directly demonstrates the desired network behavior?
- Compare EAP exchange and certificate selection to the intended authentication profile
- Walk the same path with packet and WLAN telemetry enabled
- Correlate server resource graphs, request latency and failed user sessions
- Trace both directions and inspect permit/deny counters for a test flow
Explanation
Correct Answer
D:The failure may be after route selection. Control-plane learning does not guarantee data-plane delivery.
Incorrect Answers
A:Handshake evidence identifies credential versus configuration error. By contrast, the failure may be after route selection.
B:Repeatable measurements show whether each roam causes loss. It would not resolve the documented symptom; the failure may be after route selection.
C:Matching peaks demonstrate the backend bottleneck. In this situation, the failure may be after route selection.
Question 806
A distribution switch learns an OSPF route but a test host still cannot reach the subnet. Which assumption would be most misleading when investigating this situation?
- Increase AP power to fix a portal server that is unreachable through guest policy
- Assume neighbor Full means every user application must be reachable
- Assume a successful IPv4 ping proves the IPv6 path is permitted
- Change DNS search domains before checking why the address pool changed
Explanation
Correct Answer
B:OSPF adjacency is not application connectivity. Control-plane learning does not guarantee data-plane delivery.
Incorrect Answers
A:More signal does not correct service routing. The relevant technical distinction is that oSPF adjacency is not application connectivity.
C:IPv4 and IPv6 use different addresses and filters. It would not resolve the documented symptom; oSPF adjacency is not application connectivity.
D:DNS names do not choose a client's DHCP scope. By contrast, oSPF adjacency is not application connectivity.
Question 807
A distribution switch learns an OSPF route but a test host still cannot reach the subnet. Which safeguard best reduces the deployment risk in this case?
- Retest portal onboarding from a clean device session after policy adjustment
- Alert on monitoring data age and confirm user impact before mass changes
- Pilot the corrected supplicant profile and preserve a safe enrollment network
- Record the precise failing flow and change one component at a time
Explanation
Correct Answer
D:Broad simultaneous edits obscure the defect. The failure may be after route selection.
Incorrect Answers
A:Cached browser states can hide continuing redirect problems. The relevant technical distinction is that broad simultaneous edits obscure the defect.
B:Operational decisions should use current evidence. By contrast, broad simultaneous edits obscure the defect.
C:Devices need a recovery path for certificate-profile mistakes. Here, however, broad simultaneous edits obscure the defect.
Question 808
A voice call breaks only while a handset roams between two APs. What is the most appropriate first technical change?
- Investigate RADIUS response time and server capacity rather than endpoint signal alone
- Test path MTU, interface errors and queue drops under realistic packet sizes
- Check the selected route, return path, ACL and actual firewall/state policy
- Collect roam timing, EAP/FT events and RTP loss across the handoff
Explanation
Correct Answer
D:Correlating reassociation and audio gaps isolates the transition. Repeatable measurements show whether each roam causes loss.
Incorrect Answers
A:Overloaded authentication infrastructure can delay otherwise correct exchanges. In this situation, correlating reassociation and audio gaps isolates the transition.
B:Size and load sensitivity can indicate MTU or congestion instead of simple reachability. The relevant technical distinction is that correlating reassociation and audio gaps isolates the transition.
C:Control-plane learning does not guarantee data-plane delivery. Here, however, correlating reassociation and audio gaps isolates the transition.
Question 809
A voice call breaks only while a handset roams between two APs. Which observation would best verify that the intended behavior is working?
- Correlate server resource graphs, request latency and failed user sessions
- Walk the same path with packet and WLAN telemetry enabled
- Inspect live VLAN interfaces and trunk tags against the last working snapshot
- Capture the first failed DNS or HTTP redirect request and inspect policy logs
Explanation
Correct Answer
B:Repeatable measurements show whether each roam causes loss. Correlating reassociation and audio gaps isolates the transition.
Incorrect Answers
A:Matching peaks demonstrate the backend bottleneck. It would not resolve the documented symptom; repeatable measurements show whether each roam causes loss.
C:A targeted diff isolates the missing service. Here, however, repeatable measurements show whether each roam causes loss.
D:The earliest failing step identifies the correct team. In this situation, repeatable measurements show whether each roam causes loss.
Question 810
A voice call breaks only while a handset roams between two APs. Which belief about the configuration should the team reject?
- Assume a successful IPv4 ping proves the IPv6 path is permitted
- Replace the AP solely because its management dashboard looks healthy
- Treat a strong static RSSI value near the starting AP as proof roaming is healthy
- Assume successful 64-byte ICMP proves every Ethernet payload will cross the path
Explanation
Correct Answer
C:Moving clients cross new RF and authentication boundaries. Correlating reassociation and audio gaps isolates the transition.
Incorrect Answers
A:IPv4 and IPv6 use different addresses and filters. By contrast, moving clients cross new RF and authentication boundaries.
B:Healthy management does not identify the missing client VLAN. In this situation, moving clients cross new RF and authentication boundaries.
D:Small tests do not exercise maximum frame size or sustained load. It would not resolve the documented symptom; moving clients cross new RF and authentication boundaries.
