Question 80
A site interconnect adds a third network closet but produces asymmetric return traffic. What should be included in the rollout plan to limit a foreseeable failure?
- Pilot profile assignment on a few moved devices and review negative access tests
- Keep a switch-port migration matrix and run one test client before moving the entire floor
- Test a link failure with loop-prevention settings recorded and peer-reviewed
- Document explicit failover routes and approved path symmetry exceptions
Explanation
Correct Answer
D:Changes in topology can cause stateful devices to drop asymmetric flows. A reciprocal path test identifies unexpected policy or routing asymmetry.
Incorrect Answers
A:Staged validation catches over-permissive ports before a whole-floor rollout. It would not resolve the documented symptom; changes in topology can cause stateful devices to drop asymmetric flows.
B:A phased cutover limits outage if one port profile is wrong. In this situation, changes in topology can cause stateful devices to drop asymmetric flows.
C:Recovery should not reintroduce a broadcast storm. By contrast, changes in topology can cause stateful devices to drop asymmetric flows.
Question 81
An office access layer must carry two redundant paths without causing a switching loop. What should the network engineer do to address this requirement?
- Create a dedicated IoT segment with a narrow outbound access policy
- Use the organization's supported secure onboarding and configuration-management process
- Configure approved redundant resolver and time sources reachable from management VLANs
- Select a supported aggregation or loop-prevention design based on the actual topology
Explanation
Correct Answer
D:Parallel Ethernet paths require either negotiated bundling or controlled redundancy. Both protocols affect whether frames circulate or one path is intentionally blocked.
Incorrect Answers
A:Restricted reachability limits risk from unmanaged endpoints. The relevant technical distinction is that parallel Ethernet paths require either negotiated bundling or controlled redundancy.
B:Repeatable enrollment can apply the correct template after device identity is verified. By contrast, parallel Ethernet paths require either negotiated bundling or controlled redundancy.
C:Correct name resolution and time are foundations for authentication and log correlation. It would not resolve the documented symptom; parallel Ethernet paths require either negotiated bundling or controlled redundancy.
Question 82
An office access layer must carry two redundant paths without causing a switching loop. What should the team inspect to confirm the result?
- Inspect LACP and spanning-tree state before placing the new link in production
- Compare installed port and PoE usage to the floor plan and measured uplink utilization
- Confirm assigned voice subnet, DHCP options, and a successful controller registration
- Match LLDP neighbors and switch port IDs to each installed AP in the inventory
Explanation
Correct Answer
A:Both protocols affect whether frames circulate or one path is intentionally blocked. Parallel Ethernet paths require either negotiated bundling or controlled redundancy.
Incorrect Answers
B:The acceptance test must reflect peak connectivity rather than a device count alone. The relevant technical distinction is that both protocols affect whether frames circulate or one path is intentionally blocked.
C:IP assignment alone cannot prove call-control reachability. By contrast, both protocols affect whether frames circulate or one path is intentionally blocked.
D:Neighbor discovery confirms actual placement rather than planned locations. Here, however, both protocols affect whether frames circulate or one path is intentionally blocked.
Question 83
An office access layer must carry two redundant paths without causing a switching loop. Which misconception is most likely to obstruct a correct fix?
- Connect a second unmanaged Ethernet cable and assume redundant paths cannot form loops
- Change the AP's wireless transmit power to force a better management address
- Assume enough free copper ports also means enough electrical power for all APs
- Use a different guest SSID name without applying different VLAN or role policy
Explanation
Correct Answer
A:A loop can amplify broadcasts and destabilize the entire VLAN. Parallel Ethernet paths require either negotiated bundling or controlled redundancy.
Incorrect Answers
B:Radio power cannot select the correct wired DHCP scope. In this situation, a loop can amplify broadcasts and destabilize the entire VLAN.
C:Port availability and PoE budget are separate design constraints. The relevant technical distinction is that a loop can amplify broadcasts and destabilize the entire VLAN.
D:An SSID label alone does not create network isolation. Here, however, a loop can amplify broadcasts and destabilize the entire VLAN.
Question 84
An office access layer must carry two redundant paths without causing a switching loop. What precaution is most important before the change is expanded?
- Test a link failure with loop-prevention settings recorded and peer-reviewed
- Pilot one AP with each expected SSID before cloning the profile
- Document an approved MTU value and rollback when the path includes third-party equipment
- Document explicit failover routes and approved path symmetry exceptions
Explanation
Correct Answer
A:Recovery should not reintroduce a broadcast storm. Both protocols affect whether frames circulate or one path is intentionally blocked.
Incorrect Answers
B:One missing tag can affect a particular user group across many APs. It would not resolve the documented symptom; recovery should not reintroduce a broadcast storm.
C:Inconsistent jumbo settings are difficult to troubleshoot after users move. Here, however, recovery should not reintroduce a broadcast storm.
D:Changes in topology can cause stateful devices to drop asymmetric flows. In this situation, recovery should not reintroduce a broadcast storm.
Question 85
A clinic wants guest internet access on existing APs but guest clients must not reach clinical systems. Which configuration decision most directly resolves the situation?
- Apply the approved AP port profile with required management and client VLAN transport
- Restore the correct uplink VLAN assignments and downstream gateway reachability
- Deploy an isolated guest VLAN or role with approved internet-only policy
- Design the approved VLAN-to-SVI gateway placement and required routed uplinks
Explanation
Correct Answer
C:Shared wireless hardware need not imply shared internal reachability. The boundary is meaningful only when both paths are tested.
Incorrect Answers
A:Access points may need tagged network segments beyond a single untagged VLAN. In this situation, shared wireless hardware need not imply shared internal reachability.
B:Edge migration requires the same approved VLAN path to the L3 gateway. It would not resolve the documented symptom; shared wireless hardware need not imply shared internal reachability.
D:Gateway location determines broadcast boundaries and first-hop reachability. By contrast, shared wireless hardware need not imply shared internal reachability.
Question 86
A clinic wants guest internet access on existing APs but guest clients must not reach clinical systems. Which check most directly demonstrates the desired network behavior?
- Compare switch DNS queries, synchronized clock state and server failover
- Confirm guest DHCP, external browsing and denied access to clinical subnets
- Compare installed port and PoE usage to the floor plan and measured uplink utilization
- Test representative packet sizes and inspect ingress discard counters on each hop
Explanation
Correct Answer
B:The boundary is meaningful only when both paths are tested. Shared wireless hardware need not imply shared internal reachability.
Incorrect Answers
A:Independent service tests expose missing management routes. The relevant technical distinction is that the boundary is meaningful only when both paths are tested.
C:The acceptance test must reflect peak connectivity rather than a device count alone. It would not resolve the documented symptom; the boundary is meaningful only when both paths are tested.
D:Size-dependent loss identifies an MTU mismatch rather than a general outage. By contrast, the boundary is meaningful only when both paths are tested.
Question 87
A clinic wants guest internet access on existing APs but guest clients must not reach clinical systems. Which assumption would be most misleading when investigating this situation?
- Connect a second unmanaged Ethernet cable and assume redundant paths cannot form loops
- Assume Ethernet link-up ensures all jumbo frames can cross intermediate devices
- Use a different guest SSID name without applying different VLAN or role policy
- Assume a routed uplink continues to forward every previous VLAN without additional design
Explanation
Correct Answer
C:An SSID label alone does not create network isolation. Shared wireless hardware need not imply shared internal reachability.
Incorrect Answers
A:A loop can amplify broadcasts and destabilize the entire VLAN. The relevant technical distinction is that an SSID label alone does not create network isolation.
B:Link negotiation does not negotiate end-to-end frame size. Here, however, an SSID label alone does not create network isolation.
D:L3 interfaces do not automatically trunk arbitrary Layer 2 segments. By contrast, an SSID label alone does not create network isolation.
Question 88
A clinic wants guest internet access on existing APs but guest clients must not reach clinical systems. Which safeguard best reduces the deployment risk in this case?
- Label and test each drop and retain the as-built documentation
- Leave expansion headroom and identify redundant uplink paths before ordering switches
- Check guest DNS and captive-portal continuity during upstream failover
- Stage gateway migration by subnet with DHCP and return-route checks
Explanation
Correct Answer
C:The guest design should remain secure when a link changes. The boundary is meaningful only when both paths are tested.
Incorrect Answers
A:Reliable records shorten later outage isolation. In this situation, the guest design should remain secure when a link changes.
B:The closet should not require a new chassis for the first modest growth. The relevant technical distinction is that the guest design should remain secure when a link changes.
D:Incorrect gateway changes can interrupt entire floors. Here, however, the guest design should remain secure when a link changes.
Question 89
A campus installs switches with mixed IPv4 and IPv6 devices and new clients cannot reach IPv6 services. What is the most appropriate first technical change?
- Create a dedicated IoT segment with a narrow outbound access policy
- Restore the correct uplink VLAN assignments and downstream gateway reachability
- Check the tagged management VLAN and DHCP relay or server scope for that subnet
- Verify dual-stack gateway advertisements, VLAN membership and IPv6 routing
Explanation
Correct Answer
D:IPv6 clients may depend on router advertisements and prefixes separate from IPv4 DHCP. An IPv4 ping says nothing about native IPv6 operation.
Incorrect Answers
A:Restricted reachability limits risk from unmanaged endpoints. In this situation, iPv6 clients may depend on router advertisements and prefixes separate from IPv4 DHCP.
B:Edge migration requires the same approved VLAN path to the L3 gateway. Here, however, iPv6 clients may depend on router advertisements and prefixes separate from IPv4 DHCP.
C:Incorrect tagging can direct an AP into the wrong address pool. It would not resolve the documented symptom; iPv6 clients may depend on router advertisements and prefixes separate from IPv4 DHCP.
Question 90
A campus installs switches with mixed IPv4 and IPv6 devices and new clients cannot reach IPv6 services. Which observation would best verify that the intended behavior is working?
- Inspect client IPv6 address, default router and a routed IPv6 test session
- Check the effective port role, tagged VLAN and authorization for moved endpoints
- Compare installed port and PoE usage to the floor plan and measured uplink utilization
- Check device registration, expected software level and effective port configuration
Explanation
Correct Answer
A:An IPv4 ping says nothing about native IPv6 operation. IPv6 clients may depend on router advertisements and prefixes separate from IPv4 DHCP.
Incorrect Answers
B:Actual assignments matter more than profile names. By contrast, an IPv4 ping says nothing about native IPv6 operation.
C:The acceptance test must reflect peak connectivity rather than a device count alone. It would not resolve the documented symptom; an IPv4 ping says nothing about native IPv6 operation.
D:A powered-up device may not yet have received its authorized profile. In this situation, an IPv4 ping says nothing about native IPv6 operation.
