Question 20
Two core switches must keep independent control planes while offering a paired multi-chassis downstream connection. Which approach fits?
- VSX independent control planes
- VSF unified logical switch
- Central group provisioning
- Standalone independent switches
Explanation
Correct Answer
A:VSX uses a pair with separate control planes rather than a VSF stack. VSX provides a multi-chassis pair retaining separate control planes and an inter-switch synchronization link.
Incorrect Answers
B:VSF combines supported physical members into a virtual switch with unified control and management. But this does not address the case requirement to offer multi-chassis resilience without one shared control plane.
C:Central device groups help apply and audit management policies without turning switches into one control plane. But this does not address the case requirement to offer multi-chassis resilience without one shared control plane.
D:Standalone devices retain individual control and configuration without logical stacking. But this does not address the case requirement to offer multi-chassis resilience without one shared control plane.
Question 21
A lab explicitly needs separate routing and management state on two devices. Which deployment choice preserves that?
- Standalone independent switches
- VSF unified logical switch
- Central group provisioning
- VSX independent control planes
Explanation
Correct Answer
A:Standalone operation keeps switch control separate. Standalone devices retain individual control and configuration without logical stacking.
Incorrect Answers
B:VSF combines supported physical members into a virtual switch with unified control and management. But this does not address the case requirement to operate two completely independent switch systems.
C:Central device groups help apply and audit management policies without turning switches into one control plane. But this does not address the case requirement to operate two completely independent switch systems.
D:VSX provides a multi-chassis pair retaining separate control planes and an inter-switch synchronization link. But this does not address the case requirement to operate two completely independent switch systems.
Question 22
A switch has four parallel physical uplinks to one neighbor and needs an aggregated logical interface, not a new stack. What solves it?
- VSX independent control planes
- Central group provisioning
- LACP link aggregation
- STP loop avoidance
Explanation
Correct Answer
C:LACP negotiates a compatible link bundle. LACP bundles compatible physical links into one logical aggregate but does not merge device control planes.
Incorrect Answers
A:VSX provides a multi-chassis pair retaining separate control planes and an inter-switch synchronization link. But this does not address the case requirement to aggregate member links without merging switch identities.
B:Central device groups help apply and audit management policies without turning switches into one control plane. But this does not address the case requirement to aggregate member links without merging switch identities.
D:Spanning tree suppresses redundant Layer 2 forwarding loops but does not stack devices. But this does not address the case requirement to aggregate member links without merging switch identities.
Question 23
Two unmanaged Layer 2 pathways could form a loop; no switch stacking is requested. What protocol class addresses forwarding loops?
- STP loop avoidance
- VSF unified logical switch
- VSX independent control planes
- LACP link aggregation
Explanation
Correct Answer
A:STP elects forwarding and blocked paths for loop prevention. Spanning tree suppresses redundant Layer 2 forwarding loops but does not stack devices.
Incorrect Answers
B:VSF combines supported physical members into a virtual switch with unified control and management. But this does not address the case requirement to protect a bridged topology from repeated frames.
C:VSX provides a multi-chassis pair retaining separate control planes and an inter-switch synchronization link. But this does not address the case requirement to protect a bridged topology from repeated frames.
D:LACP bundles compatible physical links into one logical aggregate but does not merge device control planes. But this does not address the case requirement to protect a bridged topology from repeated frames.
Question 24
A company needs consistent configuration across many separate sites but no virtual stacking. What platform feature is appropriate?
- Standalone independent switches
- Central group provisioning
- LACP link aggregation
- VSX independent control planes
Explanation
Correct Answer
B:Central groups can manage similar independent switches at scale. Central device groups help apply and audit management policies without turning switches into one control plane.
Incorrect Answers
A:Standalone devices retain individual control and configuration without logical stacking. But this does not address the case requirement to apply common policy to devices without a shared control plane.
C:LACP bundles compatible physical links into one logical aggregate but does not merge device control planes. But this does not address the case requirement to apply common policy to devices without a shared control plane.
D:VSX provides a multi-chassis pair retaining separate control planes and an inter-switch synchronization link. But this does not address the case requirement to apply common policy to devices without a shared control plane.
Question 25
A closet stack loses its commander but remaining members should follow the supported VSF leadership behavior. Which architecture describes the stack?
- Central group provisioning
- Standalone independent switches
- LACP link aggregation
- VSF unified logical switch
Explanation
Correct Answer
D:VSF membership implies an integrated virtual switch system. VSF combines supported physical members into a virtual switch with unified control and management.
Incorrect Answers
A:Central device groups help apply and audit management policies without turning switches into one control plane. But this does not address the case requirement to manage a multi-member logical access switch.
B:Standalone devices retain individual control and configuration without logical stacking. But this does not address the case requirement to manage a multi-member logical access switch.
C:LACP bundles compatible physical links into one logical aggregate but does not merge device control planes. But this does not address the case requirement to manage a multi-member logical access switch.
Question 26
An engineer says VSX is the same as forming one VSF control plane. Which model corrects that?
- VSF unified logical switch
- STP loop avoidance
- Standalone independent switches
- VSX independent control planes
Explanation
Correct Answer
D:VSX peers retain their own control planes and synchronize selected state. VSX provides a multi-chassis pair retaining separate control planes and an inter-switch synchronization link.
Incorrect Answers
A:VSF combines supported physical members into a virtual switch with unified control and management. But this does not address the case requirement to differentiate dual-control-plane design from unified stacking.
B:Spanning tree suppresses redundant Layer 2 forwarding loops but does not stack devices. But this does not address the case requirement to differentiate dual-control-plane design from unified stacking.
C:Standalone devices retain individual control and configuration without logical stacking. But this does not address the case requirement to differentiate dual-control-plane design from unified stacking.
Question 27
A link-bundle member fails and three others remain forwarding while the devices stay separate. Which function provides this behavior?
- STP loop avoidance
- LACP link aggregation
- VSX independent control planes
- Central group provisioning
Explanation
Correct Answer
B:LACP bundles links for capacity and member redundancy. LACP bundles compatible physical links into one logical aggregate but does not merge device control planes.
Incorrect Answers
A:Spanning tree suppresses redundant Layer 2 forwarding loops but does not stack devices. But this does not address the case requirement to preserve link aggregation across independent devices.
C:VSX provides a multi-chassis pair retaining separate control planes and an inter-switch synchronization link. But this does not address the case requirement to preserve link aggregation across independent devices.
D:Central device groups help apply and audit management policies without turning switches into one control plane. But this does not address the case requirement to preserve link aggregation across independent devices.
Question 28
A wiring closet must remain powered after loss of one independent AC feed, where the chosen chassis supports it. What hardware design helps?
- Documented transceiver interoperability
- Uplink capacity headroom
- Redundant PSUs on independent electrical feeds
- Environmental hardware compliance
Explanation
Correct Answer
C:Redundant feeds and power modules reduce one-supply failure risk. Multiple independently fed power supplies can tolerate a supply or feed failure on supported models.
Incorrect Answers
A:Validated optical modules and interface speeds prevent incompatible media assumptions. But this does not address the case requirement to continue powering a switch after one power path fails.
B:Sizing uplinks for sustained peaks and future growth avoids avoidable oversubscription bottlenecks. But this does not address the case requirement to continue powering a switch after one power path fails.
D:Temperature, airflow and physical mounting suitability matter for closets and industrial sites. But this does not address the case requirement to continue powering a switch after one power path fails.
Question 29
An access stack currently has one uplink to a single building switch; a failure isolates the floor. Which topology improves resilience?
- Documented transceiver interoperability
- Uplink capacity headroom
- Dual uplinks to distinct aggregation devices
- Environmental hardware compliance
Explanation
Correct Answer
C:Diverse upstream paths reduce a single aggregation fault. Physically diverse uplinks reduce dependence on one port, cable or upstream switch.
Incorrect Answers
A:Validated optical modules and interface speeds prevent incompatible media assumptions. But this does not address the case requirement to provide an alternate path if a switch or cable fails.
B:Sizing uplinks for sustained peaks and future growth avoids avoidable oversubscription bottlenecks. But this does not address the case requirement to provide an alternate path if a switch or cable fails.
D:Temperature, airflow and physical mounting suitability matter for closets and industrial sites. But this does not address the case requirement to provide an alternate path if a switch or cable fails.
Question 30
A core proposal emphasizes onsite replacement of a faulty interface module rather than replacing an entire unit. What capability matters?
- Dual uplinks to distinct aggregation devices
- Documented transceiver interoperability
- Modular field-replaceable components
- Redundant PSUs on independent electrical feeds
Explanation
Correct Answer
C:Field-replaceable modular assemblies limit hardware replacement scope. Modular chassis can accept supported replacement power, fans or line cards without full platform replacement.
Incorrect Answers
A:Physically diverse uplinks reduce dependence on one port, cable or upstream switch. But this does not address the case requirement to swap a line card within a supported chassis.
B:Validated optical modules and interface speeds prevent incompatible media assumptions. But this does not address the case requirement to swap a line card within a supported chassis.
D:Multiple independently fed power supplies can tolerate a supply or feed failure on supported models. But this does not address the case requirement to swap a line card within a supported chassis.
