Question Answer
Which command can be used from a PC to verify the connectivity between hosts that connect through a switch in the same LAN?ping address
A switch has 48 ports and 4 VLANs. How many collision and broadcast domains exist on the switch (collision, broadcast)?48, 4
What is the purpose of assigning an IP address to a switch?Allows remote management of the switch.
Which three statements are true about the operation of a full-duplex Ethernet network?There are no collisions in full-duplex mode. A dedicated switch port is required for each full-duplex node. The host network card and the switch port must be capable of operating in full-duplex
For what two purposes does the Ethernet protocol use physical addresses?to uniquely identify devices at Layer 2, to allow communication between different devices on the same network
How does a switch differ from a hub?A switch tracks MAC addresses of directly-connected devices.
Why will a switch never learn a broadcast address?A broadcast address will never be the source address of a frame.
If a host experiences intermittent issues that relate to congestion within a network while remaining connected, what could cause congestion on this LAN?Broadcast storms
Which address type does a switch use to make selective forwarding decisions?Destination MAC address
A switch receives a frame on one of its ports. There is no entry in the MAC address table for the destination MAC address. What will the switch do with the frame?Forward it out of all ports except the one that received it.


Question Answer
In an Ethernet network, under what two scenarios can devices transmit?when they detect no other devices are sending, when the medium is idle
View the exhibit. Which two statements are true of the interfaces on switch SW1?A hub is connected directly to FastEthernet0/5. FastEthernet0/1 is configured as a trunk link.
Which two options will help to solve the problem of a network that is suffering a broadcast storm?a router, a Layer 3 switch
The network manager has requested a 300-workstation expansion of the network. The workstations are to be installed in a single broadcast domain, but each workstation must have its own collision domain. The expansion is to be as cost-effective as possible while still meeting the requirements. Which three items will adequately fulfill the request?One IP subnet with a mask of , Seven 48-port switches, One router interface
What does a Layer 2 switch use to decide where to forward a received frame?Destination MAC address
Which two characteristics apply to Layer 2 switches?increases the number of collision domains. implements VLAN.
A network interface port has collision detection and carrier sensing enabled on a shared twisted pair network. From this statement, what is known about the network interface port?This is an Ethernet port operating at half duplex.
Which two statements describe the operation of the CSMA/CD access method?In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting .After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.
CSMA/CDcarrier sense multiple access with collision detection
