Network upgrades have been completed and the WINS server was shutdown. It was decided that NetBIOS network traffic will no longer be permitted. Which of the following will accomplish this objective?
A. Content filtering
B. Port filtering
C. MAC filtering
D. IP filtering
Answer: B
Explanation: TCP/IP port filtering is the practice of selectively enabling or disabling Transmission Control Protocol (TCP) ports and User Datagram Protocol (UDP) ports on computers or network devices.

At which of the following layers do frames exist? (Select TWO).
A. OSI model Data link layer
B. TCP/IP model Network Interface layer
C. OSI model Physical layer
D. OSI model Network layer
E. TCP/IP model Internet layer
Answer: A,B Explanation:
The data link layer is concerned with local delivery of frames between devices on the same LAN. Data-link frames, as these protocol data units are called, do not cross the boundaries of a local network. Inter-network routing and global addressing are higher layer functions, allowing data-link protocols to focus on local delivery, addressing, and media arbitration. In this way, the data link layer is analogous to a neighborhood traffic cop; it endeavors to arbitrate between parties contending for access to a medium, without concern for their ultimate destination.

Which of the following TCP ports are used by FTP? (Select TWO).
A. 20
B. 21
C. 22
D. 23
E. 25
F. 80
Answer: A,B
Explanation:
FTP uses two ports by default: 21 for sending commands, and 20 for sending data. For instance if you said “FTP <ServerName>” it would make the attempt using port 21. If the session was established, port 20 would be using for the data. NotE. These are the default ports which is what I assume you were asking. A server administrator can however configure FTP to use whatever port he defines.
