False

All that is needed to provide communication between to VLANs is a DHCP relay agent. a. True b. False

False

An unmanaged switch can still support the creation of VLANs, provided there is an interface for configuration. a. True b. False

False

Network segmentation decreases both performance and security on a network. a. True b. False

False

Only Class B and Class C networks can be subnetted. a. True b. False

False

A /24 CIDR block is equivalent to a 255.255.255.0 subnet mask. a. True b. False

True

By default, the native VLAN is the same as the default VLAN. a. True b. False

True

IPv6 addressing does not utilize classful addressing, therefore every IPv6 address is classless. a. True b. False

True

In order to identify the transmission that belong to each VLAN, a switch will add a tag to Ethernet frames that identifies the port through which they arrive at the switch. a. True b. False

True

Network segmentation at Layer 2 of the OSI model is accomplished using VLANs a. True b. False

True
