4A0-100 Exam Question 362

Which of the following best describes a repeater?

A.A passive device simply used to connect two or more cables. It does not generate or amplify any signals.

B.A device that receives a signal and based on the Layer 3 destination address makes a decision on which ports the signal should be retransmitted.

C.A device that receives a signal and based on the Layer 2 destination address, makes a decision on which ports the signal should be retransmitted.

D.A device that receives and retransmits a signal out its ports but does not do any Layer 2 analysis of the data.

4A0-100 Exam Question 363

Which of the following statements best characterize Link State Routing? (Choose two.)

A.Routers flood link information throughout the entire area.

B.Routers do not have precise knowledge of the entire network topology.

C.Routers periodically send a copy of their routing table to their neighbors.

D.Network converges quickly (within several seconds) after a topology change.

4A0-100 Exam Question 364

TCP is sending data in 5 segments with SEQ numbers 27000, 27500.28000, 28500, and 29000 respectively. During transmission, the segment with SEQ=28500 is dropped in the network. How does TCP handle this situation?

A.The receiving end station sends an ACK flag with SEQ=28000 to indicate it has received a segment out of order.

B.Once the reciever's window is full. TCP assembles the payload and determines that SEQ=28500 is missing. At this point, the reciever sends the RST flag with SEQ=28500 to Request Single Transmission of the missing segment.

C.The receiving station sends a NACK frame with SEQ=28500 requesting that the frame be retransmitted

D.TCP will collect the segments and forward them to the application layer where the SEQ numbers will be processed and a retransmit request will occur for the entire packet.

4A0-100 Exam Question 365

If a 4-port LAG is configured with the option of 'port-threshold 2' and 'action down' what will happen if the
total operational links in the LAG is 2?

A.If dynamic-cost is enabled it will adjust the cost for routing protocols such as OSPF.

B.The LAG will be changed to an operational state of 'down'.

C.The LAG will function with only 2 ports. There will be no change to the routing metric.

D.If dynamic-cost is not enabled it will adjust the cost for routing protocols such as OSPF by dividing the
link bandwidth by 2.
