The difference between asymmetric and symmetric switches is judged by _________.
Available port speeds
The wireless access point connects two different LAN standards, generally Ethernet and WiFi. Then, it must be a type of
Bridge
Which is correctly pairing an intermediary device with the standard layer it operates?
Bridge: layer 2 device
Cut-through switching is when: A.) All switch ports use the same wire speed B.) Switch ports have different wire speeds C.) The switch forwards a frame without waiting for its arrival in its entirety. D.) There is no switch learning or aging E.) Switch ports have different throughputs
C.) The switch forwards a frame without waiting for its arrival in its entirety.
Choose a CORRECT statement about the switch. A.) The switch cannot be assigned an IP address B.) The switch is also known as a multi-port repeater C.) The switch port mostly operates in the full-duplex mode D.) The risk of frame collisions gets higher as the number of hosts attached to a switch increases. E.) CSMA/CD is used to avoid frame collisions when a network is running on switches
C.) The switch port mostly operates in the full-duplex mode
How does the layer 3 switch differ from the layer 2 switch? A.) The layer 3 switch has more ports than the layer 2 switch B.) The layer 3 switch has more throughput than the layer 2 switch C.) The layer 3 switch has better network management capability than the layer 2 switch D.) The layer 3 switch port can be either a switch port or a router port. E.) The layer 3 switch port has higher security than the layer 2 switch port.
D.) The layer 3 switch port can be either a switch port or a router port. Thus, a layer 3 switch can act as a router port
Choose a CORRECT statement about the operating system of an intermediary device. A.) Hubs and repeaters need an OS to function. B.) The switch's OS does not allow modification of it's security port C.) The router's OS is about the same size as Windows or Linux developed for personal computers D.) The router's OS is generally stored in the nonvolatile flash memory E.) When the router is powered on, the OS stored in its hard disk is copied into the RAM
D.) The router's OS is generally stored in the nonvolatile flash memory
Which many NOT constitute an advanced router function? A.) Access control list for packet filtering B.) Network address translation between private and public IPs C.) Provision of dynamic IPs to requesting stations using DHCP D.) Intrusion and prevention E.) Automatic assignment of IP address to the router port
E.) Automatic assignment of an IP address to the router port
When a host station's NIC is connected to a hub, the link should use ___________ transmission.
