TESTOUT NETWORK PRO EXAM Q&A 2026
STUDY GUIDE COMPLETE QUESTIONS AND
SOLUTIONS
◍ Transport Layer Security (TLS) Answer:*** ensures that messages
being transmitted on the internet are private and tamper proof. *** is
implemented through two protocols:
*** Record can provide connection security with encryption (for
example, with DES).
*** Handshake provides mutual authentication and choice of encryption
method.
*** version 1.2 (***1.2) is an updated version that improves security
flaws found in *** 1.0 and 1.1.
◍ File Transfer Protocol (FTP) Answer:*** provides a generic method
for transferring files. It can protect access to files by requiring user
names and passwords, and it allows file transfer between dissimilar
computer systems. *** can transfer both binary and text files, including
HTML, to another host. FTP URLs are preceded by ftp:// followed by
the DNS name of the *** server. To log in to an *** server, use
ftp://username@servername.
The *** protocol does not use encryption. All data, including user
names, passwords, and files, are sent over the network as clear text.
,◍ Trivial File Transfer Protocol (TFTP) Answer:*** is similar to FTP.
It lets you transfer files between a host and an FTP server. However, it
does not provide user authentication or error detection. *** is often used
when files need to be transferred between systems quickly. Because it
does not perform error detection, *** is faster than FTP, but is
susceptible to transmission errors.
◍ Secure File Transfer Protocol (SFTP) Answer:*** uses Secure Shell
(SSH) to secure data transfers. SSH ensures that *** transmissions use
encrypted commands and data, which prevents clear text data
transmissions.
◍ Secure Copy (SCP) Answer:*** is used to securely transfer files
between systems. Like SFTP, *** relies on SSH to ensure that data and
passwords are not transmitted over the network in clear text.
◍ Simple Mail Transfer Protocol (SMTP) Answer:*** is used to route
electronic mail through the internetwork. *** is used:
Between mail servers for sending and relaying mail.
By all email clients to send mail.
By some email client programs, such as Microsoft Outlook, to receive
mail from an Exchange server.
◍ Post Office Protocol 3 (POP3) Answer:is used to retrieve email from
a remote server and download it to a local client over a TCP/IP
connection.
, An email client that uses *** for receiving mail uses SMTP for sending
mail.
◍ Internet Message Access Protocol version 4 (IMAP4) Answer:*** is
an email retrieval protocol designed to enable users to access their email
from various locations without the need to transfer messages or files
back and forth between computers. Messages remain on the remote mail
server and are not automatically downloaded to a client system.
An email client that uses *** for receiving mail uses SMTP for sending
mail.
◍ Dynamic Host Configuration Protocol (DHCP) Answer:*** is used
to automatically assign addresses and other configuration parameters to
network hosts. Using a *** server, hosts receive configuration
information at startup, reducing the amount of manual configuration
required on each host.
◍ Domain Name System (DNS) Answer:*** is a distributed system
throughout the internetwork that provides address and name resolution.
For example, the name www.mydomain.com would be mapped to a
specific IP address.
◍ Network Time Protocol (NTP) Answer:*** is used to communicate
time synchronization information between systems on a network.
