Answer the following statement true (T) or false (F)
?Match each correct item with the statement below. ?
A. ?The interface on a switch used for an end node. Devices connected to access ports are unaware of VLAN information. B. ?A software configuration that can be used to disable STP on specific ports, such as the port leading to the network's demarc. It prevents access to network links that should not be considered when plotting STP paths in a network. C. ?In CIDR notation, the forward slash plus the number of bits used for the network ID. D. ?Cisco's proprietary standard, similar to VRRP, that assigns a virtual IP address to a group of routers. At first, messages routed to the virtual IP address are handled by the active router. If the active router fails, standby routers stand in line to take over responsibility for the virtual IP address. E. ?An untagged VLAN on a switch that will automatically receive all untagged frames. F. ?The virtualization of network services in which a network controller manages these services instead of the services being directly managed by the hardware devices involved. G. ?The interface on a switch capable of managing traffic from multiple VLANs. H. ?A server that exists as a virtual machine, created and managed by virtualization software on a host, or physical, computer. I. ?An attack in which the attacker generates transmissions that appear, to the switch, to belong to a protected VLAN. J. ?A standard that assigns a virtual IP address to a group of routers. At first, messages routed to the virtual IP address are handled by the master router. If the master router fails, backup routers stand in line to take over responsibility for the virtual IP address.
