Question 186

Which of the following are TRUE statements about the router ID in OSPF? (Choose two.)

A.A router ID is not required by OSPF.

B.The system address is used as the router ID if router-id is not set.

C.The router ID is used to uniquely identify every OSPF router.

D.On the Nokia 7750 SR, the router ID is set to the highest logical IP address if router-id is not explicitly set.

Question 187

A network with address 208.40.224.0/24 is divided into /28 subnets. What is the host address range of the fourth subnetwork?

A.208.40.224.17 - 208.40.224.30

B.208.40.224.33 - 208.40.224.46

C.208.40.224.49 - 208.40.224.62

D.208.40.224.65 - 208.40.224.78

Question 188

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

C.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.

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.

Question 189

Which three of the following are important considerations when designing subnets? (Choose three.)

A.Type of physical connectivity used by each segment.

B.Number of hosts each subnetwork will support.

C.Number of subnetworks currently required.

D.Class of the network address to be used for the network.

E.Future network growth requirements.

Question 190

Which of the following is a feature of a VLAN?

A.A VLAN allows multiple Ethernet switches to be connected in a single broadcast domain.

B.A VLAN allows multiple Ethernet switches to be connected in a single collision domain.

C.A VLAN can separate ports on the same switch into different collision domains.

D.A VLAN can separate ports on the same switch into different broadcast domains.
