CompTIA A+ 220-1101 Practice Exam 3+4 By Mr.B

Front

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

Back

True

Answer explanation

The statement is True because the NetBT (NetBIOS over TCP/IP) protocol enables the use of NetBIOS services across TCP/IP networks, facilitating communication between devices.

Front

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

Back

SNMP

Answer explanation

The correct answer is SNMP (Simple Network Management Protocol), which is specifically designed for monitoring and managing network devices. SMB, NTP, and RDP serve different purposes in networking.

Front

LDAP is an example of: Authentication protocol, Address resolution protocol, Directory access protocol, File exchange protocol

Back

Directory access protocol

Answer explanation

LDAP (Lightweight Directory Access Protocol) is primarily used for accessing and maintaining distributed directory information services, making it a directory access protocol rather than an authentication or file exchange protocol.

Front

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

Back

HTTPS

Answer explanation

HTTPS (Hypertext Transfer Protocol Secure) is the protocol that secures web traffic using SSL/TLS encryption, ensuring safe communication over the internet. Other options like SFTP and FTPS are for file transfers, not web traffic.

Front

The FTP's Control Connection for administering a session is established through:

Back

TCP port 21

Answer explanation

The FTP Control Connection is established through TCP port 21, which is designated for command and control messages. TCP port 20 is used for data transfer, not for session administration.

Front

SSH protocol runs on: TCP port 21, UDP port 22, TCP port 20, TCP port 22

Back

TCP port 22

Answer explanation

SSH protocol operates over TCP, specifically using port 22. This distinguishes it from FTP, which uses ports 20 and 21. Therefore, the correct answer is TCP port 22.

Front

TCP port 25 is used by: SNMP, Telnet, FTP, SMTP

Back

SMTP

Answer explanation

TCP port 25 is primarily used by SMTP (Simple Mail Transfer Protocol) for sending emails. The other options, SNMP, Telnet, and FTP, use different ports.

Front

Which of the following TCP ports is used by the Internet Message Access Protocol (IMAP)? 143, 389, 443, 636

Back

143

Answer explanation

The Internet Message Access Protocol (IMAP) uses TCP port 143 for communication. This port allows clients to access and manage their email on a mail server, making it the correct choice among the options provided.

Front

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 to check whether data has changed in transit. True or False?

Back

True

Answer explanation

True. SNMPv1 and SNMPv2 use community strings in cleartext for authentication, while SNMPv3 enhances security with packet encryption, authentication, and hashing to ensure data integrity during transmission.

Front

TCP port 389 is the default network port for: RDP, LDAP, SMB, LDAPS

Back

LDAP

Answer explanation

TCP port 389 is the default port for LDAP (Lightweight Directory Access Protocol), which is used for accessing and maintaining distributed directory information services. RDP uses port 3389, SMB uses ports 445 and 139, and LDAPS uses port 636.
