Network+ N10-008 All-in-One Exam Guide Graded A+

Where does (did) a hub send data? A. Only to the receiving system B. Only to the sending system C. To all the systems connected to the hub D. Only to the server - Answer-To all the systems connected to the hub; A hub sends data to all the systems connected to it. What uniquely identifies every NIC? A. IP address B. Media access control address C. ISO number D. Packet ID number - Answer-Media Access Control (MAC) address What Windows utility do you use to find the MAC address for a system? A. ipconfig /all B. ipcfg /all C. ping D. mac - Answer-ipconfig /all A MAC address is known as a(n) __________ address. A. IP B. logical C. physical D. OEM - Answer-physical A NIC sends data in discrete chunks called __________.A. segments B. sections C. frames D. layers - Answer-frames; Data is sent in discrete chunks called frames. Networks use frames to keep any one NIC from hogging the wire. The MAC address of which of the following begins a frame? A. Receiving system B. Sending system C. Network D. Router - Answer-Receiving system; The frame begins with the MAC address of the receiving NIC, followed by the MAC address of the sending NIC, followed, in turn, by type of encapsulated data, the data, and FCS. A frame ends with a special bit called the frame check sequence (FCS). What does the FCS do? A. Cycles data across the network B. Verifies that the MAC addresses are correct C. Verifies that the data arrived correctly D. Verifies that the IP address is correct - Answer-Verifies that the data arrived correctly; The data is followed by a special bit of checking information called the frame check sequence, which the receiving NIC uses to verify that the data arrived correctly. Which of the following is an example of a MAC address? A. 0-255 B. 00-50-56-A3-04-0C C. SBY3M7 D. 192.168.4.13 - Answer-00-50-56-A3-04-0C; A MAC address is a 48-bit value, and no two NICs ever share the same MAC address—ever. Which layer of the OSI model controls the segmentation and reassembly of data?A. Application layer B. Presentation layer C. Session layer D. Transport layer - Answer-Transport layer; controls the segmentation and reassembly of data. Which layer of the OSI model keeps track of a system's connections to send the right response to the right computer? A. Application layer B. Presentation layer C. Session layer D. Transport layer - Answer-Session layer; keeps track of a system's connections to ensure that it sends the right response to the right computer. Which of the following topologies required termination? A. Star B. Bus C. Mesh D. Ring - Answer-bus; In a bus topology, all computers connected to the network via a main line. The cable had to be terminated at both ends to prevent signal reflection. Star-bus is an example of a _______________ topology. A. transitional B. system C. hybrid D. rampant - Answer-hybrid; Star-bus is a hybrid topology because it uses a star physical topology and a bus signal topology. Of the topologies listed, which one is the most fault-tolerant? A. Point-to-pointB. Bus C. Star D. Ring - Answer-Star; only star topology has any fault tolerance.
