and Correct Detailed Answers (Verified Answers)
A client connects to an IMAP server over port TCP/143, but this port is unsecure.
Instead, the client wants a secure connection established using Transport Layer
Security (TLS). What is the default port for the secure POP3/IMAP?
Ans: TCP port 993 or 995
The default ports for a secure connection are either transport control protocol (TCP)
port 993 (IMAPS) or 995 (POP3S), depending on the mail access protocol in use
(IMAP or POP).
The network administrator is configuring a network attached storage (NAS)
appliance. What file sharing protocol should the administrator use to allow access to
Windows, Linux, and Apple macOS clients?
Ans: The Server Message Block (SMB)
protocol that implements Windows File/Printer Sharing is specifically for use on local
networks only. Therefore, allowing access from the internet would be a security risk.
A client wishes to upload and download a few files from the network server. The
client wants to upload some of the files to a website. Which ports would establish an
active connection? (Select all that apply.)
Ans: TCP/20
TCP/21

In addition to Remote Desktop, which of the following protocols can an
administrator use for remote access administration? (Select all that apply.)
Ans: Telnet opens a plain-text, unsecured, remote console connection. Telnet uses
TCP port 23.
Secure Shell (SSH) provides the same capabilities as Telnet but encrypts the data
while transferring to the port. SSH uses TCP port 22.
During a company meeting, a technician scribbled some notes about a firewall
configuration on a whiteboard. The technician has listed only the port numbers 25
and 587. What is the purpose of these protocols that use these ports?
Ans: The ports are for message relay between SMTP servers to submit secure and
unsecure messages for delivery.
When advising a company on configuring systems, the administrator wants to
provide better information about network device status and how to monitor them in
a client manual. Which of the following is the correct protocol that maintains a
database containing statistics related to the activity of devices for review?
Ans: The Simple Network Management Protocol (SNMP)
is a framework for the management and monitoring of network devices. SNMP
requires a Syslog agent that maintains a management information base (MIB)
database. MIB holds statistics relating to the activity of the device.

A client wishes to download some files from home to upload onto the company's
website. Which ports would establish a connection for the client to achieve this?
(Select all that apply.)
Ans: tcp 20 and 21
As an alternative to static configuration, wired and wireless hosts can receive their IP
address, subnet mask, default gateway, and DNS server addresses from which
protocol? (Select all that apply
Ans: DHCP AND APIPA
Host servers have a failover mechanism when an IP configuration specifies the use of
a Dynamic Host Configuration Protocol (DHCP) server, but the host cannot contact
one.
Windows machines will default to automatic private IP addressing (APIPA) if the
DHCP service fails or if there is some connectivity error.
The IT department is setting up for outsourced management of their client firms.
The IT department has asked a server administrator to configure a Linux server and
accept remote terminal connections from clients without using passwords, along with
encrypted terminal emulations. How does the administrator set up this access?
