19.Refer to the exhibit. A student is responsible for the IP addressing, configuration and connectivity testing of the network shown in the graphic. A ping from host B to host C results in a destination unreachable but a ping from host B to host A was successful. What two reasons could account for this failure based on the graphic and partial router output for the Dallas router? (Choose two.)

• The host A is turned off.
• The Fa0/0 interface on Dallas is shutdown.
• The LAN cable is disconnected from host B.
• The S0/0/1 IP address of Dallas is improperly configured.
• The Fa0/0 interface on Dallas is in a different subnet than host B.
• The clock rate is missing on the serial link between Dallas and NYC.

• the minimum interval, measured in bit-times, that any station must wait before sending another frame
• the maximum interval, measured in bit-times, that any station must wait before sending another frame
• the 96-bit payload padding inserted into a frame to achieve a legal frame size
• the 96-bit frame padding transmitted between frames to achieve proper synchronization
• the time allowed for slow stations to process a frame and prepare for the next frame
• the maximum interval within which a station must send another frame to avoid being considered unreachable

• The hosts return to a listen-before-transmit mode.
• The hosts creating the collision have priority to send data.
• The hosts creating the collision retransmit the last 16 frames.
• The hosts extend their delay period to allow for rapid transmission.

• the device involved in the collision with the lowest MAC address
• the device involved in the collision with the lowest IP address
• any device in the collision domain whose backoff timer expires first
• those that began transmitting at the same time

• Collisions can decrease network performance.
• It is more complex than non-deterministic protocols.
• Deterministic media access protocols slow network performance.
• CSMA/CD LAN technologies are only available at slower speeds than other LAN technologies.

06.Refer to the exhibit. The switch and workstation are administratively configured for full-duplex operation. Which statement accurately reflects the operation of this link?

• No collisions will occur on this link.
• Only one of the devices can transmit at a time.
• The switch will have priority for transmitting data.
• The devices will default back to half duplex if excessive collisions occur.

• A random delay is used to ensure a collision-free link.
• A random delay value for each device is assigned by the manufacturer.
• A standard delay value could not be agreed upon among networking device vendors.
• A random delay helps prevent the stations from experiencing another collision during the transmission.

08.In the graphic, Host A has reached 50% completion in sending a 1 KB Ethernet frame to Host D when Host B wishes to transmit its own frame to Host C. What must Host B do?

• Host B can transmit immediately since it is connected on its own cable segment.
• Host B must wait to receive a CSMA transmission from the hub, to signal its turn.
• Host B must send a request signal to Host A by transmitting an interframe gap.
• Host B must wait until it is certain that Host A has completed sending its frame.

• Host A will send on to the media a broadcast frame that contains the packet.
