Question

Refer to the exhibit. A network technician is asked to design a small network with redundancy. The exhibit shows this design, with all hosts configured in the same VLAN.

What conclusion can be made about this design?

A This design will function as intended.
B Spanning-tree will need to be used.
C The router will not accept the addressing scheme.
D The connection between switches should be a trunk.
E The router interfaces must be encapsulated with the 802.1Q protocol.

Explanation

The router addressing is incorrect because both router LAN interfaces are placed in the same IPv4 subnet, 192.168.1.0/24. A router treats each physical interface as a separate Layer 3 network boundary, so its interfaces must be in different IP networks unless special bridging features are used. Since all hosts are in one VLAN, neither 802.1Q encapsulation nor a trunk link is inherently required, and the design issue is the duplicate subnet use on two router interfaces.
