QUESTION 1: If one of the links to a computer on a physical star topology is served, what will be the result? A. The entire network will stop working. B. The affected link and the adjacent network links will stop working. C. Only the affected link will stop working. D. Only the adjacent links will stop working. Answer: C In the star topology each computer is connected to a central point by a separate cable or wireless connection. Thus each computer has a dedicated link to the network central device and a break in the link between a particular computer. | N10-003 QUESTION 1 If one of the links to a computer on a physical star topology is served what will be the result A. The entire network will stop working. B. The affected link and the adjacent network links will stop working. C. Only the affected link will stop working. D. Only the adjacent links will stop working. Answer C In the star topology each computer is connected to a central point by a separate cable or wireless connection. Thus each computer has a dedicated link to the network central device and a break in the link between a particular computer and the central network device will affect only that computer.

QUESTION 2 When one connection to a host fails in a full mesh network which of the following is true A. All hosts can communicate B. No hosts can communicate C. Half of the host will lose communication D. Only the two hosts between the failed connection will lose communication Answer A In a full mesh network each node has a connection to at two other nodes. Thus should one connection fail it will have no effect on communication as all nodes will be connected to at least one other node.

Bus D. Mesh Answer D In the mesh topology each node is connected to at least three other nodes. This requires more cabling than in the ring or bus topology in which each node is connected to only two other nodes or the star topology in which each node is connected to a central hub or switch. Incorrect Answers N10-003 A In the star topology each node is connected to a central hub or switch. This requires less cabling than in the mesh topology in which each node is connected to at least three other nodes. B In the ring topology consists of a closed loop in .
