Network Protocols Flashcards
What is the function of FTP?
File exchange
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 (Secure Shell)
Telnet does the following:
Transmits data in an unencrypted form.
Enables remote login and command execution.
Provides username & password authentication.
What refers to a secure replacement for Telnet?
SSH (Secure Shell)
The SMTP protocol is used for
Sending email messages from a client device.
Which of the following answers refers to a system containing mappings of domain names to various types of data, such as numerical IP addresses?
DNS (Domain name server)
A network protocol providing an alternative solution to the manual allocation of IP addresses is known as
DHCP (Dynamic Host Configuration Protocol)
Which network protocol enables retrieving contents of an Internet page from a web server?
HTTP (Hypertext Transfer Protocol)
POP3 protocol is used for
Email retrieval
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
The function of the NetBT protocol is to allow NetBIOS services to be used over TCP/IP networks - (T/F?)
True
Which of the following answers refer to IMAP4?
Offers improved functionality in comparison to POP3.
Serves the same function as POP3.
A type of protocol used in network management systems for monitoring network-attached devices is called
Simple Network Management Protocol (SNMP)
True or false - 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).
True
LDAP (Lightweight Directory Access Protocol) is an example of
Directory access protocol
What is the name of a network protocol that secures web traffic via SSL/TLS encryption?
HTTPS (Hypertext Transfer Protocol Secure)
What are the characteristics of SMB/CIFS? (Server Message Block/Common Internet File System)
Provides shared access to files, directories, and devices.
Used mainly by computers running Microsoft Windows operating systems.
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 (Remote Desktop Protocol)
True or False: 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. 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).
True
True or False: 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.
True
True or False: 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.
True
True or False: 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.
True
Examples of connectionless protocols
DHCP - Dynamic Host Configuration Protocol
TFTP - Trivial File Transfer Protocol
Which of the following answers refer to connection-oriented protocols? (Select 2 answers)
SSH - (Secure Shell)
HTTPS - (Hypertext Transfer Protocol Secure)
Which of the answers listed below refer to common applications that make use of TCP? (Select 3 answers)
File transfer
Email communication
Web browsing
Which of the following answers refer(s) to common applications of UDP? (All that applies, select)
Video conferencing
Live streaming
Online gaming
Voice over IP (VoIP)
PAN (Personal Area Network)
Small network used for communication between personal devices, typically within in a range of a few meters.
LAN (Local Area Network)
It is a network type that covers a small geographic area.
MAN (Metropolitan Area)
A network hope that spans a large geographic area, often a country, or even global connections.
Switches
A switch sends transmissions from one port only to the destination port.
Hub
A hub sends transmissions from one port to every other port.
SDN (Software-Defined Networking)
Modern approach to managing computer networks that separates the control plane from the data plane.
2.4 GHz Frequency
Primary radio frequency band used in SOHO wireless networks, used for data transmission, the band defines 14 channels.
5GHz Frequency
Wireless frequency that is used for WiFi and offers faster speeds than 2.4 GHz but with a shorter range.
40 different channels
802.11
A set of standards for wireless local area networks (WLANs), developed and maintained by a working group IEEE.
Long-range fixed wireless
Refers to long-range WiFi networks, Omni-directional antennas send and receive signals from a 360 degree angle.
Licensed
Requiring a specific permit to operate at higher power levels; governed by FCC
Unlicensed
Lower power limits
NFC (Near Field Communication)
Allows wireless devices to communicate with other wireless devices within a range of
RFID (Radio Frequency Identification)
A technology in which digital data, burned into labels or tags, is emitted as RF waves that can be received by nearby readers.
MAC (
