Which device would you select to partition a network into VLANs?
The correct answer is C. switch. A Layer 2 switch is the correct device for partitioning a network into VLANs by logically segmenting ports into separate broadcast domains.

Why each option
A Layer 2 switch is the correct device for partitioning a network into VLANs by logically segmenting ports into separate broadcast domains.
A repeater operates at Layer 1 and only regenerates electrical signals; it has no awareness of frames, addresses, or VLANs.
A traditional bridge segments collision domains at Layer 2 but does not support VLAN configuration or 802.1Q tagging.
Managed switches implement VLAN tagging (IEEE 802.1Q) and port assignment, allowing a single physical device to create multiple isolated Layer 2 broadcast domains; VLANs are a switch-specific feature defined at Layer 2.
A router routes traffic between existing VLANs at Layer 3 but does not itself partition a network into VLANs.
A hub operates at Layer 1 and broadcasts all traffic to every port; it has no capability for logical segmentation of any kind.
