What is the function of FTP?

File exchange

Which of the answers listed below refer to common applications that make use of TCP?

File transfer Email communication Web browsing

Which network protocol enables retrieving contents of an Internet page from a web server?

HTTP

What is the name of a network protocol that secures web traffic via SSL/TLS encryption?

HTTPS

Which of the following is in use when a WINS server tries to resolve a host name into an IP address on a Windows-based LAN?

NetBIOS

What describes a IMAP4?

Offers improved functionality in comparison to POP3 Serves the same function as POP3

What are the characteristics of SMB/CIFS?

Provides shared access to files, directories, and devices Used mainly by computers running Microsoft Windows operating systems

What features describe Telnet?

Provides username & password authentication Transmits data in an unencrypted form Enables remote login and command execution

Which of the following answers refers to a Microsoft-proprietary remote-access protocol providing a user with graphical interface for connecting to another computer over a network?

RDP

A type of protocol used in network management systems for monitoring network-attached devices is called:

SNMP

A type of cryptographic network protocol for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers is known as:

SSH

What refers to a secure replacement for Telnet?

SSH

Which of the following answers refer to connection-oriented protocols?

SSH HTTPS

What is the SMTP protocol used for?

Sending email messages between mail servers Sending email messages from a client device

Which port enables the FTP's Data Connection for sending file data?

TCP port 20

Which of the following answers refer(s) to common applications of UDP?

Video conferencing Live streaming Online gaming Voice over IP (VoIP)

Transmission Control Protocol (TCP) is:

a connection-oriented protocol using a three-way handshake, which is a set of initial steps required to establish network connection.

The function of the NetBT protocol is to:

allow NetBIOS services to be used over TCP/IP networks

User Datagram Protocol (UDP) is:

an example of a connectionless protocol.

Because UDP does not support a three-way handshake while establishing a network connection, it is referred to as:

an unreliable or best-effort protocol

Of the three existing versions of the Simple Network Management Protocol (SNMP), versions 1 and 2 (SNMPv1 and SNMPv2) offer:

authentication based on community strings sent in an unencrypted form (in cleartext)

SNMPv3 provides:

packet encryption, authentication, and hashing mechanisms that allow for checking whether data has changed in transit (i.e., data integrity)

TCP supports:

retransmission of lost packets, flow control (managing the amount of data that is being sent), and sequencing (rearranging packets that arrived out of order).
