Network Protocols Flashcards
What is the function of FTP?
Email service
Directory access
Serving of web pages
File exchange
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:
TFTP
SSH
Telnet
RDP
SSH
Secure Shell is a network communication protocol that enables two computers to communicate (c.f http or hypertext transfer protocol, which is the protocol used to transfer hypertext such as web pages) and share data.
Telnet: (Select 3 answers)
Encrypts network connection
Provides username & password authentication
Transmits data in an unencrypted form
Does not provide authentication
Enables remote login and command execution
Provides username & password authentication
Transmits data in an unencrypted form
Enables remote login and command execution
is commonly used by terminal emulation programs that allow you to log into a remote host. Now replaced by more secure SSH.
Which of the answers listed below refers to a secure replacement for Telnet?
CHAP
FTP
SNMP

The SMTP protocol is used for: (Select 2 answers)
Sending email messages between mail servers
Name resolution services
Serving of web pages
Retrieving email messages from mail servers
Sending email messages from a client device
Sending email messages between mail servers
Sending email messages from a client device
A simple mail transfer protocol (SMTP) server is a communication protocol that enables you to send and receive emails. Without an SMTP server, you can’t send your email to recipients. The server also examines if an active email account is transmitting the outbound message.
Which of the following answers refers to a system containing mappings of domain names to various types of data, such as numerical IP addresses?
TCP/IP
DNS
SQL
DHCP
DNS
A Domain Name System (DNS) turns domain names into IP addresses, which allow browsers to get to websites and other internet resources. Every device on the internet has an IP address, which other devices can use to locate the device.
A network protocol providing an alternative solution to the manual allocation of IP addresses is known as:
DNS
SNMP
NAT
DHCP
DHCP
Dynamic Host Configuration Protocol (DHCP) is a network protocol that is used to configure network devices to communicate on an IP network.
Which network protocol enables retrieving contents of an Internet page from a web server?
SNMP
HTTP
SMTP
IMAP
HTTP
Hypertext Transfer Protocol (HTTP) is a method for encoding and transporting information between a client (such as a web browser) and a web server. HTTP is the primary protocol for transmission of information across the Internet.
POP3 protocol is used for:
Name resolution
Sending email messages
File exchange
Email retrieval
Email retrieval
What is POP3?
Post Office Protocol 3, or POP3, is the most commonly used protocol for receiving email over the internet.
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?
DNS
TCP/IP
NetBIOS
DHCP
NetBios
Network Basic Input/Output System. The primary purpose of NetBIOS is to allow applications on separate computers to communicate and establish sessions to access shared resources, such as files and printers, and to find each other over a local area network (LAN).
WINS: Windows Internet Name Service (WINS) is a legacy computer name registration and resolution service that maps computer NetBIOS names to IP addresses
The function of the NetBT protocol is to allow NetBIOS services to be used over TCP/IP networks.
True
False
True
NetBios over TCP/IP
NetBT is an acronym that means “NetBios over TCP/IP”. NetBios stands for “Network Basic Input Output System”. TCP/IP stands for “Transport Control Protocol/Internet Protocol”.
Which of the following answers refer to IMAP4? (Select 2 answers)
Offers improved functionality in comparison to POP3
Serves the same function as POP3
Enables sending email messages from client devices
Offers less functions than POP3
Enables email exchange between mail servers
Offers improved functionality in comparison to POP3
Serves the same function as POP3
IMAP4 clients can create, rename, and delete mailboxes (usually presented to the user as folders) on the server, and copy messages between mailboxes. Multiple mailbox support also allows servers to provide access to shared and public folders.
A type of protocol used in network management systems for monitoring network-attached devices is called:
SMB
NTP
SNMP
RDP
SNMP
SNMP is used to collect data related to network changes or to determine the status of network-connected devices. Collecting this data can help IT professionals keep their finger on the pulse of all their managed devices and applications.
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).

What is the name of a network protocol that secures web traffic via SSL/TLS encryption?
SFTP
HTTPS
FTPS
SNMP
HTTPS
Hypertext Transfer Protocol Secure (https) is a combination of the Hypertext Transfer Protocol (HTTP) with the Secure Socket Layer (SSL)/Transport Layer Security (TLS) protocol.
