Question 10
A design must terminate users, phones and printers in individual closets. Which layer should host those endpoint ports?
- Access layer placement
- Dedicated management network
- Core high-throughput transport
- Routed access design
Explanation
Correct Answer
A:Access is where endpoints connect and are classified. Access ports attach endpoints and enforce edge membership near users and devices.
Incorrect Answers
B:An independent management path reduces dependence on production user traffic for administrative access. But this does not address the case requirement to attach clients near their physical locations.
C:The core provides resilient high-capacity transit between routed distribution blocks. But this does not address the case requirement to attach clients near their physical locations.
D:A routed access design moves Layer 3 boundaries toward edge devices to limit Layer 2 fault domains. But this does not address the case requirement to attach clients near their physical locations.

- Routed access design
- Dedicated management network
- Access layer placement
Explanation
Correct Answer
A:A collapsed core combines distribution and core functions where appropriate. A smaller campus can combine aggregation and core responsibilities in a shared device pair.
Incorrect Answers
B:A routed access design moves Layer 3 boundaries toward edge devices to limit Layer 2 fault domains. But this does not address the case requirement to avoid needless tiers in a smaller topology.
C:An independent management path reduces dependence on production user traffic for administrative access. But this does not address the case requirement to avoid needless tiers in a smaller topology.
D:Access ports attach endpoints and enforce edge membership near users and devices. But this does not address the case requirement to avoid needless tiers in a smaller topology.
Question 15
A production route outage must not eliminate all switch administration access. What path should be planned?
- Core high-throughput transport
- Aggregation or distribution layer
- Access layer placement
- Dedicated management network
Explanation
Correct Answer
D:A separate management plane improves incident access. An independent management path reduces dependence on production user traffic for administrative access.
Incorrect Answers
A:The core provides resilient high-capacity transit between routed distribution blocks. But this does not address the case requirement to retain administration when production forwarding fails.
B:An aggregation layer collects access switches and can define policy and routing boundaries. But this does not address the case requirement to retain administration when production forwarding fails.
C:Access ports attach endpoints and enforce edge membership near users and devices. But this does not address the case requirement to retain administration when production forwarding fails.
Question 16
A redesign introduces dedicated building distribution switches between edge stacks and interbuilding core. What layer is being added?
- Dedicated management network
- Collapsed core design
- Aggregation or distribution layer
- Core high-throughput transport
Explanation
Correct Answer
C:The distribution role aggregates access domains. An aggregation layer collects access switches and can define policy and routing boundaries.
Incorrect Answers
A:An independent management path reduces dependence on production user traffic for administrative access. But this does not address the case requirement to define aggregation between edge and core.
B:A smaller campus can combine aggregation and core responsibilities in a shared device pair. But this does not address the case requirement to define aggregation between edge and core.
D:The core provides resilient high-capacity transit between routed distribution blocks. But this does not address the case requirement to define aggregation between edge and core.

C:A smaller campus can combine aggregation and core responsibilities in a shared device pair. But this does not address the case requirement to avoid sharing all administrative fate with user VLANs.
D:Access ports attach endpoints and enforce edge membership near users and devices. But this does not address the case requirement to avoid sharing all administrative fate with user VLANs.
Question 19
Four compatible access devices must operate as one logical switch with one management/control plane. Which technology is intended?
- VSX independent control planes
- Standalone independent switches
- VSF unified logical switch
- STP loop avoidance
Explanation
Correct Answer
C:A supported VSF stack presents a unified logical system. VSF combines supported physical members into a virtual switch with unified control and management.
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 unify multiple physical access switches into one managed device.
B:Standalone devices retain individual control and configuration without logical stacking. But this does not address the case requirement to unify multiple physical access switches into one managed device.
D:Spanning tree suppresses redundant Layer 2 forwarding loops but does not stack devices. But this does not address the case requirement to unify multiple physical access switches into one managed device.
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.
