Case 1:

At the distribution layer of a hierarchical network, what are two advantages of using Layer 3 devices instead of Layer 2 switches? (Choose two.)

creates fewer IP subnets to configure and manage
provides connectivity between different VLANs
enables traffic filtering based on subnet addresses
provides reliable connectivity to end users
reduces the number of redundant links required

Explanation: Communication between endpoints on different access layer switches occurs through the distribution layer. The distribution layer provides a boundary between the Layer 2 domain of the access layer and the Layer 3 domain of the core. This boundary provides two key functions for the LAN. On the Layer 2 side, the distribution layer creates a boundary for Spanning Tree Protocol (STP), limiting propagation of Layer 2 faults. On the Layer 3 side, the distribution layer provides a logical point to summarize IP routing information when it enters the core layer. The summarization reduces IP route tables for easier troubleshooting and reduces protocol overhead for faster recovery from failures.
