6.7.2 Ethernet and IP Protocol Quiz
What are two characteristics of IP? (Choose two.) -Guarantees delivery of packets -Does not require a dedicated end-to-end connection. -Operates independently of the network media. -Re-assembles out of order packets into the correct order at the receiver end. -Re-transmits packets if errors occur.
Does not require a dedicated end-to-end connection. Operates independently of the network media.
What is the command netstat -r used for? -To release the assigned IP address. -To display the host routing table. -To display the TCP sockets. -To renew the default gateway.
To display the host routing table.

What are two services provided by the OSI network layer? (Choose two.) -Collision detection. -Encapsulating PDUs from the transport layer. -Performing error detection. -Placement of frames on the media.
Encapsulating PDUs from the transport layer. Routing packets toward the destination.
Which function or operation is performed by the LLC sublayer? -It is responsible for media access control. -It communicates with upper protocol layers. -It adds a header and trailer to a packet to form an OSI Layer 2 PDU. -It performs data encapsulation.
It communicates with upper protocol layers.
Which statement describes a MAC address? -It identifies the source and destination addresses of hosts on the internet. -It is a physical address assigned to an Ethernet NIC by the manufacturer. -It is 128-bits in length. -It contains two portions, the network portion and the host portion.
It is a physical address assigned to an Ethernet NIC by the manufacturer.
Which two characteristics describe Ethernet technology? (Choose two.) -It is supported by IEEE 802.5 standards. -It typically uses an average of 16Mb/s for data transfer rates. -It is supported by IEEE 802.3 standards. -It uses the CSMA/CD access control method. -It uses a ring topology.
It is supported by IEEE 802.3 standards. It uses the CSMA/CD access control method.
A technician uses the ping 127.0.0.1 command. What is the technician testing? -The TCP/IP stack on a network host. -Connectivity between two PCs on the same network. -Connectivity between a PC and the default gateway. -Connectivity between two adjacent Cisco devices. -Physical connectivity of a particular PC and the network.
The TCP/IP stack on a network host.
How do hosts ensure that their packets are directed to the correct network destination? -They have to keep their own local routing table that contains a route to the loopback interface, a local network route, and a remote default route. -They always direct their packets to the default gateway which will be responsible for the packet delivery. -They search in their own local routing table for a route to the network destination address and pass this information to the default gateway. -They send a query packet to the default gateway asking for the best route.
They have to keep their own local routing table that contains a route to the loopback interface, a local network route, and a remote default route.
Why does a Layer 3 device perform the ANDing process on a destination IP address and subnet mask? -To identify the network address of the destination network. -To identify the broadcast address of the destination network. -To identify the host address of the destination host. -To identify faulty frames.
To identify the network address of the destination network.
