What is a similarity between Layer 2 and Layer 3 switches?

The correct answer is D. Both allow the implementation of VLANs. A single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a virtual local area network, virtual LAN or VLAN. LANs are…

Explanation

A single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a virtual local area network, virtual LAN or VLAN. LANs are layer 2 constructs, so they can be supported by both Layer 2 and Layer 3 switches. Not A: Layer 2 switches do not provide high level of security. Not B: Another name for logical address is IP address. Only Layer 3 switches uses IP address. Layer 2 switches uses MAC addresses. Not C: only Layer 3 switches forward packets on the network (like routers).
