Chapter 2 - Network Model Flashcards
Where does 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
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“C. Data comes into a hub through one wire and is then sent out through all the other wires. A hub sends data to all the systems connected to it.”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“What uniquely identifies every NIC? A. IP address B. Media access control address C. ISO number D. Packet ID number”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“B. The unique identifier on a network interface card is called the media access control (MAC) address.”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“What Windows utility do you use to find the MAC address for a system? A. ipconfig /all B. ipcfg /all C. ping D. mac”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“A. All versions of Windows use ipconfig /all from the command line to determine the MAC address.”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“A MAC address is known as a(n) __________ address.”
“A. IP
B. logical
C. physical
D. OEM”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.

“A NIC sends data in discrete chunks called \_\_\_\_\_\_\_\_\_\_. A. segments B. sections C. frames D. layers”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“C. Data is sent in discrete chunks called frames. Networks use frames to keep any one NIC from hogging the wire.”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“Which MAC address begins a frame? A. Receiving system B. Sending system C. Network D. Router”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“A. 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.”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“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”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“C. 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.”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“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”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“B. A MAC address is a 48-bit value, and no two NICs ever share the same MAC address—ever. 00–50–56–A3–04–0C is a MAC address. Answer D (192.168.4.13) is an IP address.”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“Which layer of the TCP/IP model controls the assembly and disassembly of data? A. Application layer B. Presentation layer C. Session layer D. Transport layer”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“D. The Transport layer controls the assembly and disassembly of data.”
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“Which layer of the OSI seven-layer 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
Excerpt From: Michael Meyers. “CompTIA Network+ All-In-One Exam Guide (Exam N10-006).” iBooks.
“C. The Session layer keeps track of a system’s connections to ensure that it sends the right response to the right computer.”
