CompTIA A+ Exam 220-1001 - Network Protocols Quiz

Which of the following describes a system that maps domain names to various types of data, such as numerical IP addresses?

)DNS (Domain Name Servers (DNS) are the Internet's equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.)

The SMTP Protocol is used for

)Sending email messages between mail servers Sending email messages from a client device (SMTP - Short for Simple Mail Transfer Protocol, a protocol for sending e-mail messages between servers. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an e-mail client using either POP or IMAP.

Which of the following is a file sharing network protocol?

AFP - AFP. (1) Short for AppleTalk Filing Protocol, the client/server file sharing protocol used in an AppleTalk network. A non-Apple network can only access data from an AppleShare file server by first translating into the AFP language. AFP over TCP/IP, a flavor of AFP, allows users to access AFP servers over TCP/IPnetworks

Transmission Control Protocol (TCP) is an example of a connectionless protocol. Because TCP doesn't support a three-way handshake while establishing a network connection, it is referred to as an unreliable or best-effort protocol.

False

A network protocol providing an alternative solution to the manual allocation of IP addresses is known as:

DHCP

LDAP is an example of

Directory access protocol LDAP - active directory is the directory service database to store the organizational based data,policy,authentication etc whereas ldap is the protocol used to talk to the directory service database that is ad or adam. LDAP sits on top of the TCP/IP stack and controls internet directory access

What is the function of POP3

Email retrieval

User Datagram Protocol (UDP) is a connection-oriented protocol using a three-way handshake, a set of initial steps required to establish a network connection. UDP 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).

False

What is the function of FTP?

File exchange

Which network protocol enables users to retrieve the 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 used when a WINS server tries to resolve a host name into an IP address on a Windows-based LAN?

NetBIOS (It uses a software protocol called NetBIOS Frames (NBF) that allows applications and computers on a local area network (LAN) to communicate with network hardware and to transmit data across the network. NetBIOS, an abbreviation for Network Basic Input/Output System, is a networking industry standard).

Which of the following are characteristic features of SMB/CIFS

Provides shared access to files, directories, and devices Used mainly by computers running Microsoft Windows operating systems SMB/CIFS - SMB "server message block" and CIFS "common internet file system" are protocols. ... However, CIFS is the extension of the SMB protocol so if someone is sharing out SMB via Samba to a legacy system still using NetBIOS it will typically connect to the Samba server via port 137, 138, 139 and CIFS is strictly port 445

Telnet

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

Which of the following is a Microsoft-proprietary remote-access protocol providing users with a graphical interface that allows them to connect to another computer on a network?

RDP (what is rdp used for. Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft, which provides a user with a graphical interface to connect to another computer over a network connection. The user employs RDP client software for this purpose, while the other computer must run RDP server software.)

IMAP is used for

Retrieving email messages from a mail server (IMAP - Essentially, the main difference of the two protocols is that POP downloads emails from the server for permanent local storage, while IMAP leaves them on the server and just caches (temporarily stores) emails locally. In other words, IMAP is a form of cloud storage)

Which of the following protocols permits automated discovery of networked services on Local Area Networks (LANs)?

SLP - The Service Location Protocol (SLP, srvloc) is a service discovery protocol that allows computers and other devices to find services in a local area network without prior configuration. SLP has been designed to scale from small, unmanaged networks to large enterprise networks.

A type of protocol used in network management systems to monitor network-attached devices is called:

SNMP - Simple Network Management Protocol (SNMP) is an application-layer protocol used to manage and monitor network devices and their functions

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, also known as Secure Shell or Secure Socket Shell, is a network protocol that gives users, particularly system administrators, a secure way to access a computer over an unsecured network. SSH also refers to the suite of utilities that implement the SSH protocol

The function of the NetBT protocol is to allow NetBIOS services to be used over TCP/IP networks.
