Question 31

It is important to distinguish public vs. private IP addresses as private IP
addresses are not routable. It is also important to know which IP addresses are
APIPA addresses and which IP addresses are loopback addresses.

Well-known protocols have port numbers they use to transmit data over that
specific protocol. For the exam, users will want to know the port numbers for
the most common protocols. Most of these protocols use well-known port
numbers.

Question 32

b. Private Class A:
c. Loopback:
d. Private Class B:
e. Private Class C:

Answer 32

a.
b.
c.
d.
e.

Question 33

For each protocol, identify the port number for the protocol:

Answer 33

IMAP:
HTTPS:
RDP:
DNS:
SSH:
SNMP:
POP3:
SMB:
L2TP:
HTTP:

Question 34

Linux offers users various software tools for troubleshooting network issues.
Many of these tools share similar syntax and functions to Windows tools. For
example, the ping command in Linux produces the same results when run in
