Simple Mail Transfer Protocol (SMTP) is the protocol used by....

...most email servers and clients to send email messages.

The Network Layer (Layer 3) prides switching and routing technologies. Examples include AppleTalk, DDP, IP, and IPX.

True

The Simple Network Management Protocol (SNMP) is used to manage devices such as ___________________ SNMP works with an SNMP agent and an SNMP management station. The agent is found on the _______________________________ and the SNMP management station serves as ________________________________.

-routers, hubs, and switches. -device that is being managed, -the communication point for the agent.

A DNS zone transfer is the process of....

....transferring a copy of the DNS zone file from the primary DNS server to a secondary DNS server.

The Transport Layer (Layer 4) provides transparent transfer of data between end systems or hosts. Examples include SPX, TCP, and UDP.

true

The Session Layer (Layer 5) establishes, manages, and terminates connections between applications. Examples include NFS, NetBIOS names, RPC, and SQL.

True

Which of the following enumeration tools provides information about users on a Linux machine? PsTools SuperScan Null session finger

finger Using the finger command on Linux machines provides information about a user. When executed, it returns information such as the user's home directory, login time, idle times, office location, and the last time they received or read mail.

VoIP uses SIP (Session Initiation Protocol) to enable...

....voice and video calls over an IP network. SIP service generally uses UDP/TCP ports 2000, 2001, 5050, and 5061.

The Simple Network Management Protocol (SNMP) is used to manage devices such as routers, hubs, and switches. SNMP works with an SNMP agent and an SNMP management station in which layer of the OSI model? Application Layer Network Layer Session Layer Transport Layer

Application Layer; The Application Layer (Layer 7) supports application and end-user processes. Examples include NFS, SNMP, Telnet, HTTP, and FTP.

Which enumeration process tries different combinations of usernames and passwords until it finds something that works? Brute force Zone transfers Exploiting SMTP Default passwords

Brute force; attacks are usually automated. A program tries different combinations of usernames and passwords until it finds something that works.

In which phase of the ethical hacking process do you gather information from a system to learn more about its configurations, software, and services? answer Sniffing Reconnaissance Scanning Enumeration

Enumeration which is the method of gathering information from a system to learn more about its configurations, software, and services. Scanning is the method of using various tools to gather in-depth information on a network. Reconnaissance is the method of gathering publicly available information about a target. Sniffing is the process of collecting information as it crosses a network.

Which of the following best describes IPsec enumeration? -Is used to manage devices such as routers, hubs, and switches. -Uses ESP, AH, and IKE to secure communication between VPN endpoints. -Uses SIP to enable voice and video calls over an IP network. -Is used by most email servers and clients to send email messages.

Uses ESP, AH, and IKE to secure communication between VPN endpoints; IPsec uses ESP (Encapsulation Security Payload), AH (Authentication Header), and IKE (Internet Key Exchange) to secure communication between virtual private network endpoints. Using enumeration tools, attackers can pull sensitive information such as the encryption and hashing algorithm, authentication type, and key distribution algorithm.
