Question
Which statement describes the sequence of processes executed by a router when it receives a packet from a host to be delivered to a host on another network?
It de-encapsulates the packet, selects the appropriate path, and encapsulates the packet to forward it toward the destination host.
What happens when a switch receives a frame and the calculated CRC value is different than the value that is in the FCS field?
The switch places the new CRC value in the FCS field and forwards the frame.
What are three characteristics of multicast transmission? (Choose three.)
Routers will not forward multicast addresses in the range of 224.0.0.0 to 224.0.0.255.
Fill in the blank.
During data communications, a host may need to send a single message to a specific group of destination hosts simultaneously. This message is in the form of a message.
Which frame forwarding method receives the entire frame and performs a CRC check to detect errors before forwarding the frame?
store-and-forward switching
What function does pressing the Tab key have when entering a command in IOS?
Which statement describes the sequence of processes executed by a router when it receives a packet from a host to be delivered to a host on another network?
It de-encapsulates the packet and forwards it toward the destination host. It receives the packet and forwards it directly to the destination host. It selects the path and forwards it toward the destination host.It de-encapsulates the packet, selects the appropriate path, and encapsulates the packet to forward it toward the destination host.
What happens when a switch receives a frame and the calculated CRC value is different than the value that is in the FCS field?
The switch drops the frame. The switch floods the frame to all ports except the port through which the frame arrived to notify the hosts of the error. The switch notifies the source of the bad frame.The switch places the new CRC value in the FCS field and forwards the frame.
What are three characteristics of multicast transmission? (Choose three.)
A single packet can be sent to a group of hosts. Multicast messages map lower layer addresses to upper layer addresses. Computers use multicast transmission to request IPv4 addresses. The source address of a multicast transmission is in the range of 224.0.0.0 to 224.0.0.255. Multicast transmission can be used by routers to exchange routing information.Routers will not forward multicast addresses in the range of 224.0.0.0 to 224.0.0.255.

What function does pressing the Tab key have when entering a command in IOS?
It exits configuration mode and returns to user EXEC mode. It completes the remainder of a partially typed word in a command. It moves the cursor to the beginning of the next line. It aborts the current command and returns to configuration mode.Explanation / Answer
