A. Fault tolerance
B. Caching engine

A technician notices a newly installed CAT5 cable is longer than the standard maximum length. Which of the following problems would this MOST likely cause?
A. Split cable
B. EMI

Answer: C
Explanation:
The maximum length for a cable segment is 100 m per TIA/EIA 568-5-A. If longer runs are required, the use of active hardware such as a repeater or switch is necessary. The specifications for 10BASE-T networking specify a 100metre length between active devices. This allows for 90metres of solid-core permanent wiring, two connectors and two stranded patch cables of 5metres, one at each end.

QUESTION 119
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: AB
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.
QUESTION 120

Explanation:
Trivial File Transfer Protocol(TFTP) is a file transfer protocol notable for its simplicity. It is generally used for automated transfer of configuration or boot files between machines in a local environment. Compared to FTP, TFTP is extremely limited, providing no authentication, and is rarely used interactively by a user.
