A type of protocol used in network management systems for monitoring network-attached devices is called:
SNMP
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 / FALSE
TRUE
LDAP is an example of:
Directory access protocol
What is the name of a network protocol that secures web traffic via SSL/TLS encryption?
HTTPS
What are the characteristics of SMB/CIFS? (Select all that apply)

RDP
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 / FALSE
TRUE
Reliable
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 / FALSE
TRUE
Unreliable
Examples of connectionless protocols include:
(2 answers)
DHCP
TFTP
Which refer to connection-oriented protocols?
(2 answers)
SSH
HTTPS
Which refer to common applications that make use of TCP?
(3 answers)
File transfer
Email communication
Web browsing
Which of the following answers refer(s) to common applications of UDP?
